IMPORTANT NOTICESPLEASE READ

For optimum efficiency and safety, we recommend that you read the manual before operating the equipment. Store this manual in a
file or binder and keep for future reference.

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 vapors or liquids in the vicinity of this or
any other appliance.

- WHAT TO DO IF YOU SMELL GAS

 Do not try to light any appliance.
 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 your 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.

Page 2

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.

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.

GENERAL
INSTALLATION
(ALL DRYERS)

GENERAL

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 for gas dryers is 24 ceiling clearance, 24
rear clearance, and 0 side clearance. Installation clearance from
all combustable material for steam dryers is 24 ceiling clearance,
24 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.

The dryer is so designed that when an operator opens the dryer
door, the basket and exhaust fan stop. Hot, dry air is properly and
effectively moved through the basket and exhausted through a lint
trap to the venting and eventually to the atmosphere. The lint
accumulates in the collector and should be removed as needed,
minimum once daily.

IMPORTANT

REPLACEMENT PARTS

IMPORTANT
Provide adequate clearance for air openings into the combustion
chamber.

Replacement parts for this dryer are available from your distributor
or by contacting the factory at the address or phone number printed
on the cover of this manual.

Gas Piping Installation

GAS PIPING
INSTALLATION

1. Gas service installation must conform with local codes, or in
the absence of local codes with the National Fuel Gas Code,

ANSI Z223.1 or the CAN/CGA-B149, Installation Codes.

2. Check rating plate located on rear wall of dryer, for type of
gas to equip the dryer and the altitude (elevation).

3. Check with the gas supplier for the gas pressure and the
proper gas supply line installation.

NOTE: 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 psi (3.5 kPa).

The dryer must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure testing
of the gas supply piping system at test pressures equal to or greater
than 1/2 psi (3.5 kPa).

CAUTION: Low gas pressure and intermittent gas will cause gas
ignition problems. This will cause inadequate drying of the clothes
load.

NATURAL GAS ONLY

NATURAL GAS ONLY: Check the gas pressure inlet supply to the
dryer, 11 inches WC pressure maximum. Check the manifold pressure,

3.5 inches WC pressure inside the dryer.

CAUTION: Gas loop piping must be installed as shown on the previ­ous page, to maintain equal pressure for all dryers connected to a
single gas service. Install other gas appliances upstream from the
loop.

Specific gas pipe size should be obtained from your supplier or refer to the
Gas Pipe Size Chart in this manual.

Steam Piping - Installation Instructions

STEAM PIPING
INSTALLATION
INSTRUCTIONS

1. Set and anchor dryer in position. Machine should be level to assure
proper steam circulation.

2. To prevent condensate draining from headers to dryer, piping should have
a minimum 12 above respective header. Do not make steam connection
to header with a horizontal or downwardly facing tee or elbow.

3. Whenever possible, horizontal runs of steam lines must drain, by gravity,
to respective steam header. Water pockets, or an improperly drained
steam header will provide wet steam, causing improper operation of dryer.
If pockets or improper drainage cannot be eliminated, install a by-pass
trap to drain condensate from the low point in the steam supply header to
the return.

4. In both steam supply and steam return line, it is recommended that each
have a union and a globe valve. This will enable you to disconnect the
steam connections and service the dryer whole your plant is in operation.

5. Before connecting trap and check valve to dryer, open globe valve in
steam supply line and allow steam to flow through dryer to flush out any
dirt and scale from dryer. This will assure proper operation of trap when
connected.

6. After flushing system, install bucket trap (with built-in strainer) and check
valve. For successful operation of dryer, install trap 18 below coil and as
near to the dryer as possible. Inspect trap carefully for inlet and outlet
markings and install according to trap manufacturer's instructions. If
steam is gravity returned to boiler, omit trap but install check valve in
return line near dryer.

PIPING
RECOMMENDATIONS

7. Install union and globe valve in return line and make final pipe connec­tions to return header.

1. Trap each dryer individually. Always keep the trap clean and in good
working condition.

2. When dryer is on the end of a line of equipment, extend header at least 4
feet beyond dryer. Install globe valve, union, check valve and by-pass trap
at end of line. If gravity return to boiler, omit trap.

3. Insulate steam supply and return line for safety of operator and safety
while servicing dryer.

4. Keep dryer in good working condition. Repair or replace any worn or
defective parts.
