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)

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. Adjust leveling
bolts on dryer (see adjustable leveling bolts in maintenance
section).

Check voltage and amperes on rating plate before
installing the dryer.

The construction of the dryers permits installation side-by­side 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.

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.

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.

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

Unpacking/General Installation (All Dryers)

GENERAL
INFORMATION

DRYER
COOL-DOWN
CYCLE

The dryer is so designed that when an operator opens the
dryer door, the basket and exhaust fan stop. 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 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 over­accumulation.

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

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 Cool­Down control automatically takes over and continues the
rotation of the fan and basket without heat until the
garment load reaches a safe cool temperature. This
function is performed at the end of each drying cycle and
continues for two minutes.

REPLACEMENT
PARTS

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

Electric connection

Dryers must be electrically grounded by a separate #14 or larger green wire from the grounding terminal
within the Service Connection Box, to a cold water pipe. 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.

See wiring diagram furnished with dryer. Do not change wiring without consulting the 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.)

All panels must be in position before operation of dryer.

The connection needs to be made in the wiring box at the back. Open the coverplate
(G) in order to reach the connection clamps.

The connection cable needs to be brought in through the opening on the side of the

wiring box.

It is necessary to ground the dryer for your personal safety and to ensure a good
operation.

Page 12

Gas connection

The gas supply pipe should be connected to the union (I), which is on the right next
to the wiring box on the back.

It is very important to have the connections done by a qualified technician, in order
to make sure that the installation is effected in accordance with the prevailing
standards and instructions.

The dryer should be connected to the type of gas, which is indicated on the serial plate.
The use of too small gas pipes can result in unsufficient gas supply, which can lead

to a bad heating-up and a poor drying quality.

I

When the dryer is used in combination with a weighing platform, the gas supply
pipe has to be made of flexible material to allow the weighing system to keep
moving freely.

Test all connections for possible leaks by means of a soap solution, but

never with a flame.

It is important to work with the right gas pressure (see technical remarks) in order to
obtain a good ignition, heating and consequently a good operation in general.

After the gas supply has been connected, the gas tap in the dryer should beturned on

(clockwise).

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.
