Fresh Air Supply Requirements ______  
Exhaust Requirements _______________  
When the dryer is operating, it draws in room air, heats it,  
passes this air through the tumbler, and exhausts it out of  
the building. Therefore, the room air must be continually  
replenished from the outdoors. If the make-up air is  
inadequate, drying time and drying efficiency will be adversely  
affected. Ignition problems and sail switch “fluttering”  
problems may result, as well as premature motor failure from  
overheating. The dryer must be installed with provisions for  
adequate combustion and make-up air supply.  
Exhaust ductwork should be designed and installed by a  
qualified professional. Improperly sized ductwork will create  
excessive back pressure, which results in slow drying,  
increased use of energy, and shutdown of the burner by the  
airflow (sail) switch, burner hi-limits, or lint chamber hi-limit  
protector thermostat. The dryer must be installed with a  
proper exhaust duct connection to the outside.  
The dryer shall not be exhausted into any gas vent, chimney,  
wall, ceiling or concealed space of a building.  
Air supply (make-up air) must be given careful consideration  
to ensure proper performance of each dryer. Fresh air  
ventilation openings shall not be blocked and/or sealed. As  
a general rule, an unrestricted air entrance from the outdoors  
of 135 inch2 (871 cm2) is required for each dryer. (Based on  
1 inch2 [6.5 cm2] per 1,000 Btu [252 kcal].)  
Caution  
This dryer produces combustible lint and must  
be exhausted to the outdoors.  
!
Improperly sized or installed exhaust ductwork can  
create a potential fire hazard.  
It is not necessary to have a separate make-up air opening  
for each dryer. Common make-up air openings are  
acceptable. However, they must be set up in such a manner  
that the make-up air is distributed equally to all the dryers.  
The ductwork should be laid out in such a way that the  
ductwork travels as directly as possible to the outdoors with  
as few turns as possible. There should be a minimum  
6-inch (15.24 cm) clearance between the back guard and  
the first bend in the ductwork for ease of servicing. Single or  
independent dryer venting is recommended. It is suggested  
that the use of 90° turns be avoided; use 30° and/or 45° bends  
instead. The radius of the elbows should preferably be  
1-1/2 times the diameter of the duct. All ductwork should be  
smooth inside with no projections from sheet metal screws  
or other obstructions, which will collect lint. When adding  
ducts, overlap the duct being connected. All ductwork joints  
must be taped to prevent moisture and lint from escaping  
into the building. Back draft dampers must be installed in all  
commonly ducted systems. Inspection doors should be  
installed at strategic points in the exhaust ductwork for  
periodic inspection and cleaning of lint from the ductwork.  
To compensate for the use of registers or louvers used over  
the openings, this area must be increased by approximately  
33%. Make-up air openings should not be located in an area  
directly near where exhaust vents exit the building.  
Allowances must be made for remote or constricting  
passageways or where dryers are located at high altitudes  
or predominantly low pressure areas.  
Note: Component failure due to dry cleaning solvent  
fumes will void the warranty.  
A = 16-inches (40.6 cm)  
B = 17-inches (43.2 cm)  
Important: It is recommended that exhaust or booster fans  
not be used in the exhaust ductwork system.  
Exhaust back pressure measured by a manometer/  
magnehelic in the exhaust duct must be no less than 0 and  
must not exceed 0.6 in WC (1.48 mb).  
Note: When the exhaust ductwork passes through a wall,  
ceiling, or roof made of combustible materials, the opening  
must be 2-inches (5.08 cm) larger than the duct (all the  
way around). The duct must be centered within this  
opening.  
As per the National Fuel Gas Code, “Exhaust ducts for  
type 2 clothes dryers shall be constructed of sheet metal or  
other noncombustible material. Such ducts shall be  
equivalent in strength and corrosion resistance to ducts  
made of galvanized sheet steel not less than 26 gauge  
(0.0195-inches [0.50 mm]) thick.”  
EXAMPLE: For a bank of four dryers, two unrestricted openings measuring  
16-inches by 17-inches (40.6 cm by 43.2 cm) are acceptable.  
Important: Make-up air must be free of dry cleaning  
solvent fumes. Make-up air that is contaminated by dry  
cleaning solvent fumes will result in irreparable damage to  
the motors and other dryer components.  
The ductwork for this appliance must be suitable for the  
appliance category in accordance with national installation  
regulations of the country of destination.  
113615-2

Outside Ductwork Protection  
To protect the outside end of the horizontal ductwork from  
the weather, a 90° elbow bent downward should be installed  
where the exhaust exits the building. If the ductwork travels  
vertically up through the roof, it should be protected from the  
weather by using a 180° turn to point the opening downward.  
In either case, allow at least twice the diameter of the duct  
between the duct opening and the nearest obstruction (refer  
to the diagram).  
Important: Do not use screens, louvers, or caps on the  
outside opening of the exhaust ductwork.

Important: For extended ductwork runs, the cross-  
sectional area of the ductwork can only be increased to an  
extent. When the ductwork approaches the maximum  
limits as noted in this manual, a professional HVAC firm  
should be consulted for proper venting information.  
Horizontal Venting  
When horizontal dryer venting is used, the length of the  
ductwork from the dryer to the outside exhaust outlet, must  
not exceed 20 feet (6.10 meters). The minimum diameter of  
this ductwork must be at least 8-inches (20.32 cm). Including  
tumbler/dryer elbow connections or elbows used for outside  
protection from the weather, no more than 1 elbow should be  
used in the exhaust duct run. If more than 1 elbow is used,  
the cross-sectional area of the ductwork must be increased.  
Vertical Venting  
When vertical dryer venting is used, the length of the ductwork  
from the dryer to the outside exhaust outlet, must not exceed  
20 feet (6.10 meters). The minimum diameter of this ductwork  
must be at least 8-inches (20.32 cm). Including tumbler/dryer  
elbow connections or elbows used for outside protection from  
the weather, no more than 3 elbows should be used in the  
exhaust duct run. If more than 3 elbows are used, the cross-  
sectional area of the ductwork must be increased.  
NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm)  
larger than the duct (all the way around). The duct must be centered  
within this opening.  
NOTE 2 Distance should be 2 times the diameter of the duct to the nearest  
obstruction.  
Multiple Dryer (Common) Venting  
Important: For extended ductwork runs, the cross-  
sectional area of the ductwork can only be increased to an  
extent. When the ductwork approaches the maximum  
limits as noted in this manual, a professional HVAC firm  
should be consulted for proper venting information.  
If it is not feasible to provide separate exhaust ducts for each  
dryer, ducts from individual dryers may be channeled into a  
“common main duct.” The individual ducts should enter the  
bottom or side of the main duct at an angle not more than  
45º in the direction of airflow. The main duct should be  
tapered, with the diameter increasing before each individual  
duct is added.  
Important: No more than 4 dryers should be connected to  
1 main common duct.  
The illustration on the next page shows the minimum cross-  
sectional area for multiple dryer round or square venting.  
These figures must be increased if the main duct run from  
the last dryer to where it exhausts to the outdoors is longer  
than 12 feet (3.656 meters) or has more than 1 elbow in it.

Grounding  
A ground (earth) connection must be provided and installed  
in accordance with local, state, and national regulations or  
codes of the country of origin. In the absence of these codes,  
grounding must conform to applicable requirements of the  
National Electrical Code ANSI/NFPA NO. 70-LATEST  
EDITION, or in Canada, the installation must conform to  
applicable Canada Standards: Canadian Electrical Codes  
Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION. The  
ground connection may be to a proven earth ground at the  
location service panel.  
For added personal safety, when possible, it is suggested  
that a separate ground wire (size per local codes) be  
connected from the ground connection of the dryer to a  
grounded cold water pipe. Do not ground to a gas pipe or  
hot water pipe. The grounded cold water pipe must have  
metal-to-metal connection all the way to the electrical ground.  
If there are any nonmetallic interruptions, such as, a meter,  
pump, plastic, rubber, or other insulating connectors, they  
must be jumped out with a wire (size per local codes) and  
securely clamped to bare metal at both ends.  
Caution  
The dryer must be grounded. A ground lug  
has been provided for this purpose.  
!
Input connection wiring must be sized properly to handle the  
dryer’s current draw. This information is printed on the dryer’s  
data label.  
Important: A strain relief must be used where the input  
wiring enters the oven assembly.  
Important: For personal safety and proper operation, the  
dryer must be grounded.  
Electrically Heated Models Only  
Provisions are made for ground connection in each dryer at  
the electrical service connection area.  
The electrical input connections are made at the rear service  
box located at the right upper section of the dryer. The ground  
connection is made to a copper lug also provided in this area.  
To gain access, remove rear service cover.  
Electrical Connections  
A wiring diagram is located behind the control panel for  
connection data.  
The only electrical input connections to the dryer are the  
3-phase (3ø) power leads (L1, L2, L3, and sometimes neutral)  
and ground. Single-phase (1ø) power for the control circuit  
and for any single-phase (1ø) motors (if present) is done  
internally to the dryer by the factory at the oven contactor.  
No single-phase (1ø) input connection is required on a  
3-phase (3ø) dryer.  
If local codes permit, power to the dryer can be made by the  
use of a flexible UL listed power cord/pigtail (wire size must  
conform to rating of dryer), or the dryer can be hard wired  
directly to the service breaker panel. In both cases, a strain  
relief must be installed where the wiring enters the dryer.  
The neutral will only be used on 4-wire service. This is typical  
for 380-416V, 50 Hz.  
For CE Models Only  
Caution  
The means for disconnection from the supply must be  
incorporated into wiring having a minimum contact separation  
of 3.0 mm in all poles.

Input connection wiring must be sized properly to handle the  
dryer’s current draw. This information is printed on the dryer’s  
data label.  
It is important that gas pressure regulators meet applicable  
pressure requirements, and that gas meters be rated for the  
total amount of all the appliance Btu being supplied.  
Important: Failure to comply with these codes or  
ordinances, and/or the requirements stipulated in this  
manual, can result in personal injury and improper  
operation of the dryer.  
Electric Models Only  
Single-Phase (1ø) Wiring Connections / Hookup  
For ease of service, the individual gas supply line of each  
dryer must have its own manual shutoff valve.  
The dryer and its individual shutoff valve must be  
disconnected from the gas supply piping system during  
any pressure testing of that system at test pressures in  
excess of 1/2 psig (3.5 kPa) for non-CE dryers or 50 mb for  
CE dryers.  
Failure to isolate or disconnect the dryer from supply as  
noted can cause irreparable damage to the gas valve,  
voiding the warranty.  
Note: The dryer must be isolated from the gas supply  
piping system by closing its individual manual shutoff valve  
during any pressure test of the gas supply system at test  
pressures equal to or less than 1/2 psig (3.5 kPa) for non-  
CE dryers or 50 mb for CE dryers.  
Warning  
Fire or explosion could result due to failure of  
isolating or disconnecting the gas supply as  
noted.  
!
Note: Undersized gas piping will result in ignition  
problems, slow drying, increased use of energy, and can  
create a safety hazard.  
The dryer must be connected to the type of heat/gas indicated  
on the data label and pressure must be confirmed. If this  
information does not agree with the type of gas available, do  
not operate the dryer. Contact the reseller who sold the dryer  
or contact the manufacturer.  
3-Phase (3ø) Wiring Connections / Hookup  
The input ratings shown on the data label are for elevations  
up to 2,000 feet (610 meters), unless elevation requirements  
of over 2,000 feet (610 meters) were specified at the time  
the dryer order was placed with the factory. The adjustment  
or conversion of dryers in the field for elevations over 2,000  
feet (610 meters) is made by changing each burner orifice.  
If this conversion is necessary, contact the reseller who sold  
the dryer or contact the manufacturer.  
Important: If connection to this appliance is made with a  
flexible hose, it must be suitable for the appliance category  
in accordance with national installation regulations of the  
country of destination, and if in doubt the installer must  
contact the supplier. The manufacturer of this appliance  
does not recommend the use of flexible gas supply line/  
hose. An external gas supply shutoff must be provided.  
Gas Information ______________________  
It is your responsibility to have all plumbing connections,  
materials, and workmanship conform to local and state  
regulations or codes of the country of destination. In the

There should be a minimum 6-inch (15.24 cm) clearance  
between the back guard and the first bend in the gas piping  
for ease of servicing. It is recommended that a gas shutoff  
valve be provided to the gas supply line of each dryer for  
ease in servicing.  
A plugged tap, accessible for a pressure gauge connection,  
must be installed in the main gas supply line immediately  
upstream of the dryers.  
Important: Pipe joint compounds that resist the action of  
natural, L.P., and butane gases must be used.  
The size of the main gas supply line (header) will vary  
depending on the distance this line travels from the gas meter  
or, in the case of L.P. gas, the supply tank, other gas-operated  
appliances on the same line, etc. Specific information  
regarding supply line size should be determined by the gas  
supplier.  
Test all connections for leaks by brushing on a soapy  
water solution (liquid detergent works well).  
Warning  
!
Never test for leaks with a flame!!!  
Note: Undersized gas supply piping can create a low or  
inconsistent pressure, which will result in erratic operation  
of the burner ignition system.

Gas Pressure Testing _________________  
For proper operation, the gas pressure must be correct,  
consistent and maintained at the gas pressure rates shown  
on page 14. Provisions are made at the gas valve for taking  
gas pressure readings.  
Steam Information ____________________  
It is your responsibility to have all plumbing connections made  
by a qualified professional to ensure that the steam plumbing  
installation is adequate and conforms with local, state, and  
country regulations or codes.  
There are 2 types of devices used to measure gas pressure.  
They are the spring/mechanical type gauge and the  
manometer. The use of the spring/mechanical type gauge is  
not recommended because they are very easily damaged  
and are not always accurate. The preferred type of gauge is  
the manometer because it is a simple device to use and is  
highly accurate. Amanometer is simply a glass or transparent  
plastic tube with a scale graduated in inches or millibar. When  
it is filled with water and pressure is applied, the water in the  
tube rises, showing the exact gas pressure.  
Care must be exercised when leveling steam dryers into final  
position. After leveling the dryer, check the downward pitch  
of the heat exchanger from front to rear with a level. Likewise,  
check the downward pitch of the return condensate manifold  
toward its outlet part. Absence of these downward pitches  
will result in probable water hammer and premature heat  
exchanger fracture and leakage.  
The presence of condensate in the steam will cause water  
hammer and subsequent heat exchanger failure. The steam  
supply connection must be taken from the top of a  
well-dripped steam main. If the supply run-out to the dryer  
exceeds 25 feet (7.6 meters), it should be dripped just before  
the control valve with a proper trap and dirt pocket.  
Gas Pressure Test Procedure  
Turn gas cock in gas supply line to “OFF” position.  
Important: Failure to comply with the requirements  
stipulated in this manual can result in component failure,  
which will void the warranty.  
50 Hz dryers: Back out miniature screw inside pressure tap  
and attach manometer.  
60 Hz dryers: Install pressure tap and attach manometer.  
Turn gas cock to “ON” position.  
Steam Coil pH Level  
Start the dryer in Heat Mode and wait for ignition. Gas  
manifold pressure should be as shown on page 14.  
The normal pH level for copper type steam coils must be  
maintained between a value of 8.5 to 9.5. For steel type  
steam coils the pH level must be maintained between a value  
of 9.5 to 10.5. These limits are set to limit the acid attack of  
the steam coils.  
Once test is complete, turn gas cock to “OFF” position.  
Remove manometer. Tighten screw inside the pressure tap  
or install plug.  
Turn gas cock to “ON” position and check for leaks with soap  
solution with main burner “ON.”  
Important: Coil failure due to improper pH level will void  
the warranty.

The minimum operating pressure for optimum results is 100 psig (689.47  
kPa).  
It is the installer’s or owner’s responsibility to see that the  
required water pressure, pipe size, or connections are  
provided. The manufacturer assumes no responsibility if  
the fire suppression system is not connected, installed, or  
maintained properly.  
Installation Instructions  
To ensure an adequate supply of steam is provided, be sure  
that the steam supply lines and steam return lines are sized  
and laid out as stipulated in this manual. Inadequate steam  
supply lines and steam return lines or improper steam  
plumbing will result in poor performance and can cause  
component failure. Clean, dry steam must be provided to  
the dryer.  
Installation  
Water Supply  
The fire suppression system must be supplied with a minimum  
water pipe size of 1/2-inch (12.7 mm) and be provided with 40  
psi +/- 20 psi (2.75 bar +/- 1.37 bar) of pressure.  
Important: Steam coil failure due to water hammer by wet  
steam will void the warranty.  
If the rear area of the dryer or the water supply is located in  
an area where it will be exposed to cold/freezing  
temperatures, provisions must be made to protect these water  
lines from freezing.  
The presence of condensate in the steam supply line will  
cause water hammer and subsequent heat exchanger (steam  
coil) failure. The steam supply connection into the main  
supply line must be made with a minimum 10-inch (25.4 cm)  
riser. This will prevent any condensate from draining towards  
the dryer.  
Warning  
If the water in the supply line or water solenoid  
valve freezes, the fire suppression system will  
be inoperative!!  
!
The steam supply line to the dryer must include a 12-inch  
(30.48 cm) riser along with a drip trap and check valve. This  
will prevent any condensate from entering the steam coil.  
Water Connections  
Flexible hoses or couplings must be used. The dryer vibrates  
slightly when it runs and this will cause the steam coil  
connections to crack if they are hard piped to the supply and  
return mains.  
The water connection is made to the 3/4”-11.5 NH hose  
adaptor, which is shipped in the tumbler and must be installed  
to the 1/2” N.P.T. water connection, located at the upper rear  
of the dryer. A flexible supply line/coupling must be used in  
an effort to avoid damaging the electric water solenoid valve.  
Shutoff valves for each dryer should be installed in the supply  
line, return line, and drip trap return line. This will allow the  
dryer to be isolated from the supply main and the return main  
if the dryer needs maintenance work.  
Note: The 3/4”-11.5 NH is a standard hose coupling screw  
thread. It is not to be confused with 3/4” N.P.T. The  
sealing of an NH connection is made with a washer  
opposed to the mating threads of an N.P.T. assembly. The  
2 thread designs are not compatible.  
Install an inverted bucket steam trap and check valve at least  
12-inches (30.48 cm) below the steam coil as close to the  
coil as possible. A trap with a minimum capacity of 272 lb  
(123.37 kg) of condensate per hour at 125 psi (8.62 bar) is  
needed for each unit. (Based on 2 times the steam  
consumption per hour.)  
It is recommended that a filter or strainer be installed in the  
water supply line.  
The supply line and the return line should be insulated. This  
will save energy and provide for the safety of the operator  
and maintenance personnel.  
Important: Flexible supply line/coupling must be used.  
Solenoid valve failure due to hard plumbing connections  
will void warranty.  
Water pockets in the supply line, caused by low points, will  
provide wet steam to the coil possibly causing steam coil  
damage. All horizontal runs of steam supply piping should  
be pitched 1/4-inch (6.35 mm) for every 1 foot (0.31 meters)  
back towards the steam supply header causing the  
condensate in the line to drain to the header. Install a bypass  
trap in any low point to eliminate wet steam.  
The dryer is to be connected to the water mains using a  
new hose set and the old hose set should not be reused.  
Electrical Requirements  
No independent external power source or supply connection  
is necessary. The 24-volt power to operate the fire  
suppression system is accomplished internally in the dryer  
(from the dryer controls).  
Important: Flexible hoses/couplings must be used. Coil  
failure due to hard plumbing connections will void the  
warranty.

Note: Water column pressure requirements (measured at  
the pressure tap of the gas valve body) must be verified.  
Electrical power must be provided to the dryer  
at all times. If the main electrical power supply  
to the dryer is disconnected, the fire suppression  
system is inoperative!!  
!
Important: In most cases there is no regulator provided in  
an L.P. dryer. The water column pressure must be  
regulated at the source (L.P. tank), or an external regulator  
must be added to each dryer.  
Preparation for Operation/Start-Up __  
The following items should be checked before attempting to  
operate the dryer:  
Electrical Dryers  
Check to ensure that electric oven/contactor assembly is  
activating.  
• Read all “CAUTION,” “WARNING,” and “DIRECTION”  
labels attached to the dryer.  
Safety Related Circuits  
Make a complete operational check of all safety related  
circuits:  
• Check incoming supply voltage to be sure that it is the  
same as indicated on the data label. In the case of 208  
VAC or 240 VAC, the supply voltage must match the  
electric service exactly.  
• Door Switch(es)  
• GAS MODELS – Check to ensure that the dryer is  
connected to the type of heat/gas indicated on the dryer  
data label.  
• Hi-Limit Thermostats  
• Sail Switch  
• GAS MODELS – Be sure that all gas shutoff valves are  
in the open position.  
Make a complete operational check of all operating controls.  
• Be sure all back panels (guards) and electric box covers  
are in place.  
Tumbler Coating  
The tumbler is treated with a protective coating. We suggest  
dampening old garments or cloth material with a solution of  
water and nonflammable mild detergent and tumbling them  
in the tumbler to remove this coating.  
• Be sure the service doors are closed and securely in  
place.  
• Be sure the lint door/drawer is securely in place.  
• Rotate the tumbler (drum) by hand to be sure it moves  
freely.  
Microprocessor Programs/Selections  
• Check bolts, nuts, screws, terminals, and fittings for  
tightness and security.  
Each microprocessor controller (computer) has been  
preprogrammed by the factory with the most commonly used  
parameter (program) selections. If computer program  
changes are required, refer to the computer programming  
manual, which was shipped with the dryer.  
• Check that the vent is connected to the dryer and is  
exhausted to the outdoors.  
• STEAM MODELS – Check to ensure all steam shutoff  
valves are open.  
Preoperational Instructions __________  
Preoperational Test __________________  
Important: For more detailed information regarding the  
microprocessor controller (computer), refer to the  
microprocessor user’s manual included with the dryer.  
All dryers are thoroughly tested and inspected before leaving  
the factory. However, a preoperational test should be  
performed before the dryer is publicly used. It is possible  
that adjustments have changed in transit or due to marginal  
location (installation) conditions.  
Coin Models  
Microprocessor Controller (Computer)  
Turn on electric power to the dryer.  
When the microprocessor controller (computer) is in the ready  
state, the L.C.D. screen will display “Ready, Insert $XX.XX  
(amount) to Start”.  
Refer to the Operating Instructions for starting your particular  
model dryer.  
Insert coin(s). Once the correct “Amount to Start” has been  
inserted, the L.C.D. will display “Select Temperature”.  
Gas Dryers  
Open all shutoff valves.  
Select temperature by pressing “HI,” “MED,” or “LO.” The  
cycle will start and the L.C.D. will display the Dry Cycle  
selected and the remaining time.  
When a gas dryer is first started (during initial start-up), it  
has a tendency not to ignite on the first ignition attempt. This  
is because the gas supply piping is filled with air, so it may  
take a few minutes for the air to be purged from the lines.  
The dryer will continue through the drying and cooling cycles,  
until the vended time has expired.  
Note: During the purging period, check to be sure that all  
gas shutoff valves are open.  
Note: To stop the dryer, open main door. Continuation of  
the cycle will resume only after the door has been closed  
and any one of the 3 temperature selections is pressed.  
Agas pressure test should be taken at the gas valve pressure  
tap of each dryer to ensure that the water column pressure is  
correct and consistent.

or the manufacturer, be sure to give them the correct  
model number and serial number so that your parts order  
can be processed in an expeditious manner.  
Non-Coin Models  
Microprocessor Controller (Computer)  
The L.E.D. display reads “READY” (no cycle in progress).  
Press the letter on the keypad corresponding to the cycle  
desired (e.g. key “D”).  
Warranty Information _________________  
Returning Warranty Cards  
Before any dryer leaves the factory test area, a warranty card  
is placed on the inside of the main door glass. These warranty  
cards are intended to serve the customer where we record  
the individual installation date and warranty information to  
better serve you should you file a warranty claim.  
The dryer will then start (i.e. blower, tumbler, and heat).  
The L.E.D. display will read MANUAL DRYING CYCLE D,  
___MIN REMAIN.  
Note: The dryer can be stopped at any time by pressing  
the “STOP/CLEAR” key, at this time the dryer will go into a  
cycle pause. If the “STOP/CLEAR” key is pressed again at  
this point, the cycle that was in progress will be cancelled  
and returned to the “READY” state.  
If a warranty card did not come with your dryer, contact the  
Warranty Department or the Service Department at +1 (508)  
678-9000.  
When the programmed drying time has expired, the non-  
coin microprocessor controller (computer) will proceed into  
the Cool Down Cycle.  
Important: A separate warranty card must be completed  
and returned for each individual dryer.  
Once the Cool Down Cycle begins at the end of the heat  
cycle, the L.E.D. display will read COOL DOWN TEMP  
__/__ MINUTES remaining. At the end of the heat cycle, the  
dryer will shut off the heat and continue the fan and tumbler  
until the Cool Down Time or temperature is reached.

Routine Maintenance _________________  
Cleaning  
Clean any lint accumulation in and around the motor(s) casing  
opening.  
Aprogram and/or schedule should be established for periodic  
inspection, cleaning, and removal of lint from various areas  
of the dryer, as well as throughout the ductwork system. The  
frequency of cleaning can best be determined from  
experience at each location. Maximum operating efficiency  
is dependent upon proper airflow. The accumulation of lint  
can restrict this airflow. If the guidelines in this section are  
met, the dryer will provide many years of efficient, trouble  
free, and most importantly, safe operation.  
Note: To prevent damage, avoid cleaning and/or touching  
ignitor/flame-probe assembly.  
Every 6 Months  
Inspect and remove lint accumulation in customer furnished  
exhaust ductwork system and from dryer’s internal exhaust  
ducting.  
Note: The accumulation of lint in the exhaust ductwork can  
create a potential fire hazard.  
Warning  
Lint from most fabrics is highly combustible.  
!
Do not obstruct the flow of combustion and ventilation air.  
Check back draft dampers in the exhaust ductwork.  
Inspect and remove any lint accumulation, which can  
cause the damper to bind or stick.  
The accumulation of lint can create a potential  
fire hazard. Keep dryer area clear and free from  
combustible materials, gasoline, and other flammable  
vapors and liquids.  
A back draft damper that is sticking partially closed can  
result in slow drying and shutdown of heat circuit safety  
switches or thermostats.  
Note: Suggested time intervals shown are for average  
usage, which is considered 6 to 8 operational (running)  
hours per day.  
When cleaning the dryer cabinet(s), avoid using harsh  
abrasives. A product intended for the cleaning of  
appliances is recommended.  
Important: Dryer produces combustible lint and must be  
exhausted to the outdoors. Every 6 months, inspect the  
exhaust ducting and remove any lint buildup.  
7 Days After Installation  
and Every 12 Months Thereafter  
Suggested Cleaning Schedule  
Every Third or Fourth Load  
Clean the lint screen every third or fourth load. A clogged lint  
screen will cause poor dryer performance. The lint door/  
drawer is located just below the loading door of the dryer.  
Open the lint door/drawer, brush the lint off the lint screen,  
and remove the lint. Inspect lint screen and replace if torn.  
A competent professional should inspect bolts, nuts, screws,  
setscrews, grounding connections and nonpermanent gas  
connections (unions, shutoff valves, and orifices). Belts  
should be examined. Cracked or seriously frayed belts should  
be replaced. Complete an operational check of controls and  
valves. Complete an operational check of all safety devices  
(lint door/drawer switch, door switches, sail switch, and  
hi-limit thermostats).
