Dryer Enclosure Requirements _______

Commercial Type II

Bulkheads and partitions should be made of noncombustible material.

NOTE: Allowances must be made for opening the control door.

A The requirement to allow the load door to open completely

is 38-inches (96.5 cm).

B A minimum overhead clearance of 12-inches (30.48 cm) is

required. 18-inches (45.72 cm) is recommended.

C Dryer should be positioned a minimum of 12-inches (30.48

cm) away from the nearest obstruction. 24-inches (60.96 cm) is recommended for ease of installation, maintenance,

and service. D 2-inches (5.08 cm) minimum is required. E Flooring in front of the dryer must be lower than the dryer

cabinet to allow the lint door to open. F Dryers may be positioned sidewall to sidewall, however a

1/16” (1.5875 mm) minimum allowance must be made for

the opening and closing of the lint door, along with the

removal of panels during maintenance. G Dryer must protrude 1-inch (2.54 cm) from the surface of

any bulkhead or partition around the dryer to allow the

control door to open. H The minimum clearance from the top of the dryer to the

10 American Dryer Corp. WFR 113546-11

Fresh Air Supply Requirements _______

This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in the national installation regulations.

When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler, and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and sail switch “fluttering” problems may result, as well as premature motor failure from overheating. The dryer must be installed with provisions for adequate combustion and make-up air supply.

Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. As a general rule, an unrestricted air entrance from the outdoors of 250

(1,612.9 cm2) is required.

inch It is not necessary to have a separate make-up air opening

for each dryer. Common make-up air openings are acceptable. However, they must be set up in such a manner that the makeup air is distributed equally to all the dryers.

To compensate for the use of registers or louvers used over the openings, this area must be increased by approximately 33%. Make-up air openings should not be located in an area directly near where exhaust vents exit the building.

Allowances must be made for remote or constricting passageways or where dryers are located at high altitudes or predominantly low pressure areas.

NOTE: Component failure due to dry cleaning solvent fumes will void the warranty.

A = 22-3/8” (56.8 cm) B = 22-3/8” (56.8 cm)

Exhaust Requirements ________________

Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will create excessive back pressure, which results in slow drying, increased use of energy, and shutdown of the burner by the airflow (sail) switch, burner hi-limits, or lint chamber hi-limit protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.

The dryer shall not be exhausted into any gas vent, chimney, wall, ceiling or concealed space of a building.

The design of the flue system shall be such that any condensate formed when operating the appliance from cold shall either be retained and subsequently re-evaporated or discharged.

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.

Improperly sized or installed exhaust ductwork can create a potential fire hazard.

The ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns as possible. There should be a minimum 6-inch (15.24 cm) clearance between the back guard and the first bend in the ductwork for ease of servicing. Single or independent dryer venting is recommended. It is suggested that the use of 90° turns be minimized; use 30° and/or 45° bends instead. The radius of the elbows should preferably be 1-1/2 times the diameter of the duct. All ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, overlap the duct being connected. All ductwork joints must be taped to prevent moisture and lint from escaping into the building. Back draft dampers must be installed in all commonly ducted systems. (This dryer comes equipped with a back draft damper installed.) Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

IMPORTANT: Exhaust back pressure measured by a manometer/magnehelic in the exhaust duct must be no less than 0 and must not exceed 0.7 in WC (1.7 mb).

NOTE: It is recommended that exhaust or booster fans not be used in the exhaust ductwork system except where necessary to maintain exhaust back pressure (in the exhaust duct) between zero and 0.7 inch water column. Where employed, booster fans must not activate the dryer airflow proving switch (sail switch) when the dryer is not in operation.

EXAMPLE: For a bank of four dryers, two unrestricted openings measuring 22-3/8” by 22-3/8” (56.8 cm by 56.8 cm) are acceptable. With louvers, two openings measuring 25.8” x 25.8” (65.5 cm x 65.5 cm) are acceptable.

IMPORTANT: Make-up air must be free of dry cleaning solvent fumes. Make-up air that is contaminated by dry cleaning solvent fumes will result in irreparable damage to the motors and other dryer components.
