WARNING: To avoid fire hazard, do not dry articles containing foam rubber or similar texture materials.
Do not put into this dryer flammable items such as baby bed mattresses, throw rugs,undergarments
(brassieres, etc.) and other items which use rubber as padding or backing. Rubber easily oxidizes causing
excessive heat and possible fire. These items should be air dried.
WARNING: Synthetic solvent fumes from drycleaning machines create acids when drawn through the
dryer. These fumes cause rusting of painted parts, pitting of bright or plated parts, and completely
removes the zinc from galvanized parts, such as the tumbler basket. If drycleaning machines are in the
same area as the tumbler, the tumbler's make-up air must come from a source free of solvent fumes.
WARNING: Do not operate without guards in place.
WARNING: Check the lint trap often and clean as needed but at least a minimum of once per day.
WARNING: Alterations to equipment may not be carried out without consulting with the factory and
only by a qualified engineer or technician. Only Manufacturer parts may be used.
WARNING: Remove clothes from dryer as soon as it stops. This keeps wrinkles from setting in and
reduces the possibility of spontaneous combustion.
WARNING: Be safe - shut main electrical power and gas supply off externally before attempting
service.
WARNING: Never use drycleaning solvents, gasoline, kerosene, or other flammable liquids in the dryer.
FIREANDEXPLOSIONWILLOCCUR. NEVERPUTFABRICSTREATEDWITHTHESELIQUIDS
INTO THE DRYER. NEVER USE THESE LIQUIDS NEAR THE DRYER..
WARNING:Do not place items exposed to cooking oils in your dryer. Items contaminated with cooking
oils may contribute to a chemical reaction that could cause a load to catch fire.
WARNING: Never let children play near or operate the dryer. Serious injury could occur if a child
should crawl inside and the dryer is turned on.
WARNING: Never tumble fiberglass materials in the dryer unless the labels say they are machine
dryable. Glass fibers break and can remain in the dryer. These fibers cause skin irritation if they
become mixed with other fabrics.
WARNING: Before operating gas ignition system - purge air from natural gas or propane gas lines
per manufacturer’s instructions.
WARNING: To reduce the risk of electric shock, disconnect this appliance from the power supply
before attempting any user maintenance other than cleaning the lint trap. Turning the controls to the
OFF position does not disconnect this appliance from the power supply.

Rules for Safe Operation of Your Dryer
RULES
1. Be sure your dryer is installed properly in accordance with
the recommended instructions.
2. CAUTION
Be safe - Shut main electrical power supply and gas supply
off externally before attempting service.
3. CAUTION
a. Never use dry cleaning solvents: gasoline,
kerosene, or other flammible liquids in the dryer.
FIREAND EXPLOSION WILLOCCUR!
b. Never put fabrics treated with these liquids into
the dryer.
c. Never use these liquids near the dryer.
d. Always keep the lint screen clean; a full lint screen
may be a fire hazard.
e. Never use heat to dry items that contain plastic,
foam, or sponge rubber, or rags coated with wax
or paint. The heat may damage the material or create
a fire hazard. Rubber easily oxidizes, causing excessive
heat and possible fire. Never dry the above items in
the dryer.
4. Never let children play near or operate the dryer.
Serious injury will occur if a child should crawl inside and
the dryer is turned on.
5. Never use the dryer door opening and top (or the lint
drawer) as a step stool.
6. Read and follow manufacturer's instructions on packages
of laundry and cleaning aids. Heed any warnings or
precautions.
7. Never tumble fiberglass materials in the dryer unless the
labels say they are machine dryable. Glass fibers break
and can remain in the dryer and could cause skin
irriatation if they become mixed into other fabrics.
8. Reference - Lighting and shutdown instructions and
wiring diagrams are located on the rear wall of the dryer
cabinet.
NOTE:
It is best to run a properly sized load of rags and/or old
towels through one or two cycles prior to drying in
service. This process will remove any films or residual
coatings left by the manufacturing processes.
RULES FOR SAFE
OPERATION OF YOUR
DRYER

Page 9
Rules for Safe Operation of Your Dryer
CAUTION
Synthetic solvent fumes from dry cleaning machines create acids
when drawn through the dryer. These acid fumes cause rusting of
painted parts, pitting of bright plated parts and completely
removes the zinc from galvanized metal parts, such as the tumbler
basket.
If the dry cleaning machines are in the same area as the
tumbler, then the tumbler make-up air must come from
a source free of solvent fumes.
ENERGYSAVINGTIPS
1. Install dryer so that you can use short, straight venting.
Turns, elbows and long vent tubing tend to increase drying
time. Longer dry time means the use of more energy and
higher operating costs.
2. Operate dryer using full-size loads. Very large loads use
extra energy. Very small loads waste energy.
3. Dry lightweight fabrics separately from heavy fabrics.
You'll use less energy and get more even drying results by
drying fabrics of similar weight together.
4. Clean the lint screen after each load. A clean lint screen
helps give faster, more economical drying.
5. Don't open the dryer door while drying. You let warm air
escape from the dryer into the room.
6. Unload your dryer as soon as it stops. This saves having to
re-start your dryer to remove wrinkles.
ELEVATIONSABOVE 2,000 FEET
Input ratings shown on the rating plate (serial tag) are for elevations up to
2,000 feet. For elevations above 2,000 feet, rating should be reduced at a
rate of 4% for each 1,000 feet above sea level.

1. After loading the dryer tumbler with water washed clothes load, proceed to
close the loading door. For better drying, do not load dryer with combina-
tion of garments that twist.
2. Turn the 60-minute drying timer to the desired drying time. The drying
cycle light will be on and indicate the drying. The light shuts off when
drying time is complete. (See figure 1)
3. Turn the 15-minute cooling cycle timer to the desired cool down time. (Note:
Dryer will not start unless some cooling time is selected!). After the
drying cycle is completed, then the cooling cycle time will automatically
operate. The cooling light will be on and indicate the cooling of the clothes
load. The light shuts off when cooling time is completed. (See figure 1 )
4. TemperatureSelector- Select temperature per type of load being dried in
the dryer. (See figure 2 )

a. The fan motor will operate.
b. The basket will rotate.
c. The heat source will be energized.
d. The heated air mix with the water washed clothes to evaporate the
moisture from the garments.
e. The thermostats will function to maintain a safe temperature through
out the drying cycle.
f. The heat will be shut off and the motor will continue to run to cool the
dry load to a desired handling temperature.
8. When the drying timer completes its time, then the cooling timer will be
energized and the cooling light will be “On”. When the cooling light will
stay “On” and the “End-of-Cycle” light will be “On”. The “End-of-Cycle”
light will go off when the “Start/Stop” switch is turned to “Off” or “O”. At
the end of the cool-down cycle, the clothes load is dry.

Service Savers
To help you troubleshoot the dryer, we list below the most
common reasons for service calls and some answers to the
problems. Before you call service, please review the following
items:
DRYERWON'TSTART
1. Is the door completely closed?
2. Are the controls set to the “on” position?
3. Is there time on both timers?
4. Did you push the “pushtostart” button?
5. Has a fuse blown or a circuit breaker tripped?
6. Are the fuses tight?
7. Check for low voltage.
DRYERWON'THEAT
1. Is the dryer set for “cooling time” rather than
“drying time”?
2. Are the gas valve in the dryer and the gas shut off
valve on the main gas line turned on?
3. Check for low or intermittant gas pressure.
CLOTHESARENOTSATISFACTORILYDRY
1. Timed cycle - Did you allow enough heating time
before the cool-down part of the cycle?
2. Is the lint screen blocked?
3. Is the exhaust duct to the outside clean and not
blocked? (A blocked exhaust will cause slow
drying and other problems.)
4. (For Moisture Control models) Was the moisture
level setting incorrect? (Too high?)
