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 Manufacturers 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 Information

GENERAL
INFORMATION

DRYER
COOL-DOWN

The dryer is so designed that when an operator opens the dryer door,
the basket and exhaust fan stops. You can expect fast drying from a
laundry dryer. Hot, dry air is properly and effectively moved through
the basket and exhausted through a lint trap to the atmosphere. The
dryer comes equipped with an inclined, self-cleaning lint screen. In
this system, lint accumulates on the underside of the screen until a
blanket approximately 1/4" thick is formed. This blanket of lint will
fall from the screen to the bottom of the dryer cabinet and should be
removed daily, or as required, to prevent an over accumulation.

Permanent press, durable press and other modern day fabrics require
the care that your laundry dryers now provide.

At the end of the drying cycle, a timed cool-down control
automatically takes over and continues the rotation of the fan and
basket without heat until the garment load reaches a safe cool
temperature (single timer models only). This function is performed at
the end of each drying cycle and continues for two minutes.
Dryers must be electrically grounded by a separate #14 or larger

Page 16

ELECTRICAL
CONNECTIONS

Grounding Instructions (Illustration)

green wire from the grounding terminal within the service
connection box to a cold water pipe, or through the fourth green
wire properly grounded and connected to the grounding terminal. In
all cases, the grounding method must comply with local electrical
code requirements; or in the absence of local codes, with the National

Electrical Code, ANSI/NFPA 70 or the Canadian Electrical Code,
CA C22.1.

ELECTRICAL
CONTROLS

SERVICING

See wiring diagram furnished with dryer. Your dryer is completely
wired at the factory and it is only necessary for the electrician to
connect the power leads to the wire connectors within the service
connection box on the rear of the dryer. Do not change wiring
without consulting factory as you may void the factory warranty. Do
not connect the dryer to any voltage or current other than that
specified on the dryer rating plate. (Wiring diagram is located on
rear wall of dryer.)

Caution: Label all wire prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous operation.

Verify proper operation after servicing.

«Attention. Lors des opérations dentretien
des commandes, ètiqueter tous les fils avant
de les dèconnecter. Toute erreur de câblage
peut être une source de danger et de panne»

Piping Recommendations

PIPING
RECOMMENDATIONS

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.

STEAM HEATING
UNITS

1. Keep steam coils clean.

2. Check periodically and clean as often as required.

3. Remove lint and dirt accumulation from coil fins periodically
as dirty lint-laden coil fins decrease the efficiency of steam­heated dryers.

Page 18

Gas Piping Installation

GAS PIPING
INSTALLATION

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

4. Check with utilities company for proper gas pressure and gas
supply line.

5. Natural gas onlycheck the gas pressure inlet supply to
dryer, 11 inches water column maximum. Manifold
pressure3.5 inches water column pressure.

6. L.P. gas onlycheck the gas pressure inlet supply to dryer,
13 inches water column maximum. Manifold pressure11
inches water column pressure.

CAUTION: Low gas pressure and intermittent gas will cause
gas ignition problems and inadequate drying of laundry.

Page 19

Gas Piping Installation (Illustration)

The dryer and its 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 it's individual manual shutoff
valve during any pressure testing of the gas supply piping system at test pressures equal to or less
than 1/2 psi (3.5 kPa).

Page 20

Gas Service Installation Instructions

GAS SERVICE
INSTALLATION
INSTRUCTIONS

The size of the gas service pipe is dependant upon many variables,
such as tees, lengths, etc. Specific pipe size should be obtained from
the gas supplier. Refer to the Gas Pipe Size chart in this manual
for general gas pipe size information.

CAUTION: Gas loop piping must be installed as illustrated
to maintain equal gas pressure for all dryers connected to a
single gas service

Other gas-using appliances should be connected upstream
from the loop.

GAS PRESSURE
REGULATOR FOR
LIQUIFIED
PETROLEUM GASES

WARNING:
LIQUIFIED PETROLEUM GASES ONLY !

A gas pressure regulator for liquified petroleum gases is not
furnished on gas heated clothes dryers. This regulator is normally
furnished by the installer. In accordance with American Gas

Association (AGA) standards, a gas pressure regulator, when
installed indoors, must be equipped with a vent limiter or a vent line
must be installed from the gas pressure regulator vent to the outdoors.

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
imporperly 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 3/4" union and 3/4" globe valve. This will
enable you to disconnect the steam connections and service
the dryer while 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.

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