113284-1 Maytag Co. 7

Dryer Enclosure Requirements ______

Bulkheads and partitions should be made of non-combustible material.

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

A The requirement to allow the door to open completely is

35-inches (88.9 cm).

B A minimum overhead clearance of 6-inches (15.24 cm)

is required.

C Dryer should be positioned a minimum of 16-inches

(40.64 cm) away from the nearest obstruction. 30-inches (76.2 cm) is recommended for ease of installation,

maintenance, and service. D 1/16” (1.5875 mm) minimum is required. E Flooring should be level or below dryer cabinet for ease

of removing panels during maintenance. 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 control door, along

with the removal of panels during maintenance.

A = 22-inches (55.88 cm) B = 20-inches (50.8 cm)

EXAMPLE: For a bank of four 60 Hz dryers, 2 unrestricted openings measuring 22-inches by 20-inches (55.88 cm by

50.8 cm) are acceptable. 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.

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.

Fresh Air Supply Requirements ______

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. Fresh air ventilation openings shall not be blocked and/or sealed. As a general rule, an unrestricted air entrance from the outdoors of 220 inch (Based on 1 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 make-up air is distributed equally to all the dryers.

[6.5 cm2] per 1,000 Btu [252 kcal].)

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

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.

As per the National Fuel Gas Code, “Exhaust ducts for type 2 clothes dryers shall be constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 26 gauge (0.0195inches [0.50 mm]) thick.”

8 Maytag Co. 113284-1

!

WARNING

Fire Hazard Use a heavy metal vent. Do not use a plastic vent. Do not use a metal foil vent. Failure to follow these instructions can result in

death or fire.

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 dryer top 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 avoided; 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. Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

Single Dryer Venting

IMPORTANT: For extended ductwork runs, the crosssectional area of the ductwork can only be increased to an extent. When the ductwork approaches the maximum limits as noted in this manual, a professional HVAC firm should be consulted for proper venting information.

IMPORTANT: It is recommended that exhaust or booster fans not be used in the exhaust ductwork system.

Exhaust back pressure measured by a manometer/ magnehelic in the exhaust duct must be no less than 0 and must not exceed 0.6 in WC (1.48 mb).

NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be centered within this opening.

The ductwork for this appliance must be suitable for the appliance category in accordance with national installation regulations of the country of destination.

Outside Venting Protection

To shelter the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it should be protected from the weather by using a 180° turn to point the opening downward. In either case, allow at least twice the diameter of the duct between the duct opening and the nearest obstruction (refer to the diagram).

IMPORTANT: Do not use screens, louvers, or caps on the outside opening of the exhaust ductwork.

113284-1 Maytag Co. 9

The illustration below shows the minimum cross-sectional area for multiple dryer round or square venting. These figures must be increased if the main duct run from the last dryer to where it exhausts to the outdoors is longer than 12 feet (3.66 meters) or has more than 1 elbow in it.

Multiple Dryer (Common) Venting

IMPORTANT: For extended ductwork runs, the crosssectional area of the ductwork can only be increased to an extent. When the ductwork approaches the maximum limits as noted in this manual, a professional HVAC firm should be consulted for proper venting information.

If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be channeled into a “common main duct.” The individual ducts should enter the bottom or side of the main duct at an angle not more than 45º in the direction of airflow. The main duct should be tapered, with the diameter increasing before each individual duct is added. The minimum diameter of the individual ductwork must be at least 10-inches (25.4 cm).

NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm)

larger than the duct (all the way around). The duct must be centered within this opening.

NOTE 2 Distance should be 2 times the diameter of the duct to the nearest

Preparation for Operation / Start-Up _

The following items should be checked before attempting to operate the dryer:

• Read all “WARNING” and “DIRECTION” labels attached to the dryer.

• Check incoming supply voltage to ensure that it is the same as indicated on the data label.

• Ensure that all gas shutoff valves are in the open position.

• Ensure all back panels (guards) and electric box covers are in place.

• Ensure the service doors are closed and securely in place.

• Ensure the lint door/drawer is securely in place.

• Rotate the tumbler (drum) by hand to ensure it moves

freely.

• Check bolts, nuts, screws, terminals, and fittings for tightness and security.

• Check that the vent is connected to the dryer and is exhausted to the outdoors.

Preoperational Test __________________

All dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions.

Turn on electric power to the dryer. Refer to the operating instructions below for starting your

particular model dryer. Open all shutoff valves. When a gas dryer is first started (during initial start-up), it

has a tendency not to ignite on the first ignition attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for the air to be purged from the lines.

NOTE: During the purging period, check to be sure that all gas shutoff valves are open.

Tumbler Coating

The tumbler is treated with a protective coating. We suggest dampening old garments or cloth material with a solution of water and nonflammable mild detergent and tumbling them in the tumbler to remove this coating.

Microprocessor Programs / Selections

Each microprocessor controller (computer) has been preprogrammed by the factory with the most commonly used parameter (program) selections. If computer program changes are required, refer to the computer programming manual which was shipped with the dryer.

Operating Instructions _______________

IMPORTANT: For more detailed information regarding the microprocessor controller (computer), refer to the microprocessor user’s manual included with the dryer.

Microprocessor Controller (Computer)

When the microprocessor controller (computer) is in the ready state, the L.C.D. screen will display “To Start Insert $XX.XX”.

Insert coin(s). Once the correct “Amount to Start” has been inserted, the L.C.D. will display “Select Cycle”.

Select temperature by pressing HEAVY DUTY, NORMAL, or DELICATE. The cycle will start and the L.C.D. will display the Dry Cycle selected and the remaining time.

The dryer will continue through the drying and cooling cycles, until the vended time has expired.

NOTE: To stop the dryer, open main door. Continuation of the cycle will resume only after the door has been closed and any one of the three temperature selections is pressed.

Shutdown Instructions _______________

If the dryer is to be shutdown (taken out of service) for a period of time, the following must be performed:

Discontinue power to the dryer either at the external disconnect switch or the circuit breaker.

Discontinue the fuel supply: close external gas shutoff valve. Also close internal gas shutoff valves.

Routine Maintenance _________________

Cleaning

A program and/or schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer, as well as throughout the ductwork system. The frequency of cleaning can best be determined from experience at each location. Maximum operating efficiency is dependent upon proper airflow. The accumulation of lint can restrict this airflow.

NOTE: Suggested time intervals shown are for average usage, which is considered 6 to 8 operational (running) hours per day.

Suggested Cleaning Schedule

Every Third or Fourth Load

Clean the lint screen every third or fourth load. A clogged lint screen will cause poor dryer performance. The lint door/ drawer is located just below the loading door of the dryer. Open the lint door/drawer, brush the lint off the lint screen, and remove the lint. Inspect lint screen and replace if torn.

NOTE: To remove the lint drawer from the dryer, pull the drawer out loosen the TORX rails. This allows the metal clips to rotate and allow the drawer to be fully removed. Reverse the above process for installation.

®

screws on the sides of the

Every 6 Months

Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from dryer’s internal exhaust ducting.

NOTE: Do not obstruct the flow of combustion and ventilation air. Check back draft dampers in the exhaust ductwork. Inspect and remove any lint accumulation, which can cause the damper to bind or stick.

A back draft damper that is sticking partially closed can result in slow drying and shutdown of heat circuit safety switches or thermostats.

When cleaning the dryer cabinet(s), avoid using harsh abrasives. A product intended for the cleaning of appliances is recommended.

Adjustments

7 Days After Installation and Every 12 Months Thereafter

Inspect bolts, nuts, screws, setscrews, grounding connections and nonpermanent gas connections (unions, shutoff valves, and orifices). Belts should be examined. Cracked or seriously frayed belts should be replaced. Complete an operational check of controls and valves. Complete an operational check of all safety devices (lint door/drawer switch, door switches, sail switch, and hi-limit thermostats).

IMPORTANT: The frequency of cleaning the lint screen can best be determined from experience at each location.

Weekly

Clean lint accumulation from lint chamber, thermostat, and microprocessor temperature sensor area.

90 Days

WARNING

Electrical Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical

shock.

NOTE: To prevent damage, avoid cleaning and/or touching ignitor/flame-probe assembly.

Remove lint from gas valve burner area with a dusting brush or vacuum cleaner attachment.

Clean any lint accumulation in and around the motor(s) casing opening.
