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 Manufacture’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
TREATEDWITHTHESELIQUIDS INTO THE DRYER.NEVERUSETHESE
LIQUIDSNEARTHEDRYER..
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.

Electric connection
Theconnection needstobe madeinthe wiringboxattheback. Open thecoverplate
(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.
115 and 208-240 V - 1 ph
The mains wires (Ll) and (L2) should be connected to the 2 left blocks and the
yellow/green grounding wire (PE) should be connected to the grounding block.
208-240 and 480 V - 3 ph
The 3 mains wires (L1), (L2) and (L3) should be connected to the 3 left blocks and
the yellow/green grounding wire (PE) should be connected to the grounding
block.
380-415V - 3 ph
The 3 mains wires (L1), (L2) and (L3) should be connected to the 3 left blocks,
the blue neutral (N) should be connected to the right block and the yellow/green
grounding wire (PE) should be connected to the grounding block.
G
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
voidthe factorywarranty. DONOT CONNECTTHEDRYERTOANYVOLTAGEORCURRENTOTHER

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.
Thedryer shouldbeconnected tothetype ofgas, whichisindicated ontheserial 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.
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.
I
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).
Test all connections for possible leaks by means of a soap solution, but
never with a flame.

Gas Piping Installation
1. The installation must conform with local codes, or in the
absence of local codes with the National Fuel Gas Code as,
ANSI Z223.1 or the CAN/CGA-B149, Installation Codes.
2. Check identification nameplate for type of gas for dryer.
3. Checkthe altitude of dryer.
4. Check with utilities company for proper gas pressure and gas
supplyline.
5. Natural gas only—check the gas pressure inlet supply to
dryer,11”watercolumn(27.4mbar)maximum.Manifold
pressure—3.5” water column (8.8 mbar) pressure .
6. L.P. gas only—manifold pressure—13” water column (32.4

Gas Piping Installation (Illustrations)
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 (.04 bar).
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 (.04 bar).

Page 16
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.

WARNING:
LIQUIFIEDPETROLEUMGASESONLY!
A gas pressure regulator for liquified petroleum gases is not
furnished on the 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
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
thereturn.
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. Afterflushingsystem,install bucket trap(withbuilt-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
andinstallaccordingto 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.
