Important Safety Instructions
Save These Instructions
WARNING
To reduce the risk of fire, electric shock, or injury to
persons when using your dryer, follow these basic
precautions:
W034
• Read all instructions before using the dryer.
• Install this dryer according to the INSTALLATION IN-
STRUCTIONS. Refer to the EARTH/GROUND INSTRUC-
TIONS in the INSTALLATION manual for the proper earth/
ground connection of the dryer. All connections for electrical
power, earth/ground and gas supply must comply with local
codes and be made by licensed personnel when required. Do
not do it yourself.
• Do not install or store the dryer where it will be exposed to
water and/or weather.
• Do not dry articles that have been previously cleaned in,
washed in, soaked in, or spotted with gasoline or machine
oils, vegetable or cooking oils, cleaning waxes or chemicals,
dry-cleaning solvents, thinner, anything containing chemicals
such as in mops and cleaning cloths, or other flammable or
explosive substances as they give off vapors that could ignite,
explode or cause fabric to catch on fire by itself.
• Items that have been soiled with substances such as cooking
oil, acetone, alcohol, petrol, kerosene, spot removers, turpen-
tine, waxes and wax removers, should be washed in hot water
with an extra amount of detergent before being dried in the
tumble dryer.
• To reduce the risk of fire, DO NOT DRY plastics or articles
containing foam or latex rubber or similarly textured rubber-
like materials, such as shower caps, water proof textiles, rub-
ber-backed articles, and clothes or pillows filled with foam
rubber pads.
• Do not tumble fiberglass curtains and draperies unless the la-
bel says it can be done. If they are dried, wipe out the cylinder
with a damp cloth to remove particles of fiberglass.
• Do not allow children to play on or in the dryer. Close super-
vision of children is necessary when the dryer is used near
children. This appliance is not intended for use by persons
(including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerning the use
of the appliance by a person responsible for their safety. This
is a safety rule for all appliances.
• Do not reach into the dryer if the cylinder is revolving.
• Use the dryer only for its intended purpose, drying clothes.
ALWAYS follow the fabric care instructions supplied by the
garment manufacturer and only use the dryer drum to dry tex-
tiles that have been washed in water.
Safety Information
Part No. 512680R10 © Copyright, Alliance Laundry Systems LLC - DO NOT COPY or TRANSMIT 7

• Always read and follow manufacturer’s instructions on pack-
ages of laundry and cleaning aids. Heed all warnings or pre-
cautions. To reduce the risk of poisoning or chemical burns,
keep them out of reach of children at all times (preferably in a
locked cabinet).
• Remove laundry immediately after the dryer stops.
• DO NOT operate the dryer if it is smoking, grinding or has
missing or broken parts or removed guards and/or panels. DO
NOT tamper with the controls or bypass any safety devices.
• Dryer will not operate with the loading door open. DO NOT
bypass the door safety switch by permitting the dryer to oper-
ate with the door open. The dryer will stop tumbling when the
door is opened. Do not use the dryer if it does not stop tum-
bling when the door is opened or starts tumbling without
pressing the START mechanism. Remove the dryer from use
and call the service person.
• ALWAYS clean the lint filter after every load. A layer of lint
in the filter reduces drying efficiency and prolongs drying
time. Keep area around the exhaust opening and adjacent sur-
rounding area free from the accumulation of lint, dust and
dirt. The interior of the dryer and the exhaust duct should be
cleaned periodically by qualified service personnel.
• Do not repair or replace any part of the dryer, or attempt any
servicing unless specifically recommended in the user-main-
tenance instructions or in published user-repair instructions
that you understand and have the skills to carry out. AL-
WAYS disconnect the electrical power to the dryer before at-
tempting service. Disconnect the power cord by grasping the
plug, not the cord.
• If supply cord is damaged, it must be replaced by a special
cord or assembly available from the manufacturer or its serv-
ice agent.
• Before the dryer is removed from service or discarded, re-
move the door to the drying compartment.
• Failure to install, maintain, and/or operate this machine ac-
cording to the manufacturer’s instructions may result in con-
ditions which can produce bodily injury and/or property dam-
age.
NOTE: The WARNING and IMPORTANT SAFETY IN-
STRUCTIONS appearing in this manual are not meant
to cover all possible conditions and situations that may
occur. Observe and be aware of other labels and pre-
cautions that are located on the machine. They are in-
tended to provide instruction for safe use of the ma-
chine. Common sense, caution and care must be exer-
cised when installing, maintaining, or operating the
dryer.
Always contact your dealer, distributor, service agent or the man-
ufacturer about any problems or conditions you do not under-
stand.

Figure 5
• DO NOT use plastic, thin foil or type B ducting. Rigid metal
duct is recommended.
• Locate dryer so exhaust duct is as short as possible.
• Be certain old exhaust ducts are cleaned before installing your
new dryer.
• Use 4 inch [102 mm] diameter rigid or flexible metal duct.
• The male end of each section of duct must point away from
the dryer.
• Use as few elbows as possible.
• Use of duct tape or pop-rivets on all seams and joints is rec-
ommended, if allowed by local codes. DO NOT use sheet
metal screws or fasteners on exhaust pipe joints which extend
into the duct and catch lint.
• Ductwork that runs through unheated areas must be insulated
to help reduce condensation and lint build-up on pipe walls.
• Install backdraft dampers in multi-dryer installations.
• In mobile home installations, dryer exhaust duct must be se-
cured to mobile home structure.
• Dryer exhaust duct MUST NOT terminate under mobile
home.
• Dryer exhausts 220 cfm per unit (measured at back of dryer).
• DO NOT install flexible duct in concealed spaces, such as a
wall or ceiling.
• Static pressure in exhaust duct should not be greater than 0.6
inches water column [1.5 cm water column], measured with
manometer placed on exhaust duct 2 feet [610 mm] from dry-
er (check with dryer running and no load). In multi-dryer in-
stallations, all dryers connected to the main collector duct
should be operating when pressure is checked.
• Exhausting dryer in hard-to-reach locations can be done by
installing 521P3 Flexible Metal Vent Kit (available as option-
al equipment at extra cost).
• Sufficient make-up air must be supplied to replace the air ex-
hausted by the dryer. The free area of any opening for outside
air must be at least 40 in.2 [260 cm2] per unit.
• Energy efficient buildings with low air infiltration rates
should be equipped with an air exchanger that can accommo-
Installation

date on demand make-up air needs in the laundry room. These
devices can be obtained through your building contractor or
building material suppliers.
• Do not draw make-up air from a room containing a gas fired
water heater, a dry cleaner or a hair salon.
• Failure to exhaust dryer properly will void warranty.
NOTE: Venting materials are not supplied with the dry-
er (obtain locally).
IMPORTANT: DO NOT block the airflow at the bottom
of the dryer’s front panel with laundry, rugs, etc. Block-
age will decrease airflow through the dryer, thus reduc-
ing the efficiency of the dryer.
Exhaust Direction
The dryer can be exhausted to the outdoors through the back, left,
right or bottom of the dryer. EXCEPTION: Gas dryers cannot be
vented out the left side because of the burner housing.
Dryer is shipped from factory ready for rear exhaust.
Exhausting the dryer through sides or bottom can be accomplish-
ed by installing a Directional Exhaust Kit, 528P3, available as
optional equipment at extra cost.
IMPORTANT: DO NOT block the airflow at the bottom
of the dryer’s front panel with laundry, rugs, etc. Block-
age will decrease airflow through the dryer, thus reduc-
ing the efficiency of the dryer.
Exhaust System
For best drying results, recommended maximum length of ex-
haust system is shown in Table 2 .
To prevent backdraft when dryer is not in operation, outer end of
