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.
FIREANDEXPLOSIONWILLOCCUR. NEVERPUTFABRICSTREATED WITHTHESELIQUIDS
INTOTHEDRYER.NEVERUSETHESELIQUIDSNEAR 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)
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: Use spirit level on top of dryer. The use of shims are acceptable for
this procedure.
Check voltage and amperes on rating plate before installing the dryer.
On gear reducer models, remove screw and insert red vent attached to reducer.
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 12” (305 mm) ceiling clearance, 24” (610 mm) rear
clearance, and 0” side clearance.
Before operating dryer, open basket door and remove blocking between front
panel and basket. Read the instruction tags, owner's manual, warnings, etc.
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 for approximately 2
seconds.
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 circulation.
The lint screen must be kept clean daily to insure proper air circulation
throughout the dryer.
IMPORTANT

STEAM PIPING INSTALLATION
1. Set and anchor dryer in position. Machine should be level to
assure proper steam circulation.
2. Topreventcondensatedrainingfromheadersto dryer,piping
shouldhaveaminimum12”(305mm)above respective
header.Donotmakesteamconnectiontoheaderwitha
horizontal or downwardly facing tee or elbow.
3. Wheneverpossible,horizontalrunsofsteamlinesmustdrain,
bygravity,to respective steamheader. Water pockets,oran
improperly drained steam header will provide wet steam,
causingimproperoperation of dryer.Ifpockets or improper
drainage cannot be eliminated, install a bypass trap to drain
condensatefromthelowpoint inthesteamsupplyheaderto
thereturn.
4. Inbothsteamsupplyandsteamreturnline,itisrecommended
thateach have a3/4” (20mm) unionand3/4” (20mm) globe
valve. This will enable you to disconnect the steam
connections and service the dryer while your plant is in
operation.
5. Beforeconnecting trapandcheckvalveto dryer,open globe
valveinsteam supplyline and allowsteam to flowthrough
dryer to flush out any dirt and scale from dryer. This will
assure proper operation of trap when connected.
6. Afterflushingsystem,installbuckettrap(withbuilt-in
strainer) and check valve. For successful operation of dryer,
install trap 18" (458 mm) below coil and as near to the dryer
as possible. Inspect trap carefully for inlet and outlet
markingsandinstallaccordingtotrapmanufacturer’s
instructions.If steamisgravity returnedto boiler,omittrap
but install check valve in return line near dryer.
7. Installunionand globevalveinreturnlineandmake final

1. Trap each dryer individually. Always keep the trap clean and
ingoodworkingcondition.
2. Whendryerisontheendof aline ofequipment,extend
