WARNING: For your safety, the information in this manual must be followed
to minimize the risk of fire or explosion or to prevent property damage,
personal injury, or loss of life.
- Do not store or use gasoline or other flammable liquids or vapors in the
vicinity of this or any other appliance.
- WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliances.
• Do not touch any electrical switch; do not use any phone in your building.
• Clear the room, building, or area of all occupants.
• Immediately call your gas supplier from a neighbor's phone. Follow the
gas supplier's instructions.
• If you cannot reach the gas supplier, call the fire department.
Installation and service must be performed by a qualified installer, service
agency or the gas supplier.
WARNING: In the event the user smells gas odor, instructions on what to do must be
posted in a prominent location. This information can be obtained from the local gas
supplier.
WARNING: Wear Safety Shoes to prevent injuries.
WARNING: Purchaser must post the following notice in a prominent location:
FOR YOUR SAFETY
Do not store or use gasoline or other flammable vapors
and liquids in the vicinity of this or any other appliance.
WARNING: A clothes dryer produces combustible lint and should be exhausted outside the
building. The dryer and the area around the dryer should be kept free of lint.
WARNING: Be safe, before servicing machine, the main power should be shut off.
IMPORTANT NOTICES—PLEASE READ

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’s 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.
FIRE AND EXPLOSION WILL OCCUR. NEVER PUT FABRICS TREATED WITH THESE
LIQUIDS 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.

UNPACKING/GENERAL INSTALLATION (ALL DRYERS)
This dryer is packed in a large wooden crate.
Upon arrival of the equipment, any damage in shipment should
be reported to the carrier immediately.
Upon locating permanent location of a unit, care should be taken
in movement and placement of equipment.
See outline clearance diagrams for correct dimensions.
Remove all packing material such as: tape, manuals, skid, etc.
Leveling:Usespirit level on top ofdryer.The use of shimsareacceptable
forthis procedure.
Check voltage and amperes on rating plate before installing the
dryer.
The construction of the dryers permits installation side-by-side
to save space or to provide a wall arrangement. Position dryer
for the least amount of exhaust piping and elbows, and allow
free access to the rear of dryer for future servicing of belts,
pulleys and motors. Installation clearance from all combustable
material is 0” ceiling clearance, 0” rear clearance, and 0” side
clearance.
IMPORTANT
Opening the clothes loading door deactivates the
door switch to shut off the motors, fan, gas, steam, or
electric element. To restart the dryer, close the door
and press in the push to start button and hold briefly.
IMPORTANT
This dryer is designed for a capacity maximum load.
Overloading it will result in long drying times and
damp spots on some clothes.
IMPORTANT
Maximum operating efficiency is dependent upon
proper air curculation. The lint screen must be kept
cleaned daily to insure proper air circulation
throughout the dryer.
