Important Information ________________

Receiving and Handling

The dryer is shipped in a protective stretch wrap cover with protective cardboard corners and top cover (or optional box) as a means of preventing damage in transit. Upon delivery, the dryer and packaging, and wooden skid should be visually inspected for shipping damage. If any damage is noticed, inspect further before delivering carrier leaves.

Dryers damaged in shipment:

All dryers should be inspected upon receipt and before they are signed for.

If there is suspected damage or actual damage, the trucker’s receipt should be so noted.

If the dryer is damaged beyond repair, it should be refused.

Those dryers, which were not damaged in a damaged shipment, should be accepted, but the number received and the number refused must be noted on the receipt.

If you determine that the dryer was damaged after the trucker has left your location, you should call the delivering carrier’s freight terminal immediately and file a claim. The freight company considers this concealed damage. This type of freight claim is very difficult to get paid and becomes extremely difficult when more than a day or two passes after the freight was delivered. It is your responsibility to file freight claims.

Dryer or parts damaged in transit cannot be claimed under warranty.

Freight claims are the responsibility of the consignee, and all claims must be filed at the receiving end. The manufacturer assumes no responsibility for freight claims or damages.

IMPORTANT: The tumbler section of the dryer must be transported and handled in an upright position at all times.

Unpacking/Setting Up _________________

Remove protective shipping material (i.e., plastic wrap and optional shipping box) from dryer.

NOTE: The access keys for the service doors are included in the information packet shipped in the tumbler. These keys should be removed and put in a safe place yet made accessible because some will be needed throughout various phases in the installation of the dryer.

Dryers are shipped with a coin box and coin box faceplate only. The coin box lock is not included and must be purchased elsewhere or the lock can be ordered as a parts order from the manufacturer.

The dryer can be moved to its final location while still attached to the skid or with the skid removed. To unskid the dryer, locate and remove the four bolts securing the base of the dryer to the wooden skid. Two are at the rear of the base, and two are located in the front. Once the bolts are removed, slide the dryer off the skid.

With the skid removed, to make it easier to slide the dryer into its final position, slightly lower all four leveling legs, so that the dryer will slide on the legs instead of the base frame. The dryer is equipped with four leveling legs, one at each corner of the dryer base. The hex head adjustment bolts for the two front leveling legs are located directly behind the lower access door, and the rear two adjustments are directly behind the lower rear back (guard) panel.

Location of the Dryer _________________

Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such codes or ordinances the location must conform with the National

Fuel Gas Code ANSI.Z223.1 LATEST EDITION, or in Canada, the installation must conform to applicable Canadian

Standards: CAN/CGA-B149.1-M91 (Natural Gas) or CAN/

CGA-B149.2-M91 (L.P. Gas) or LATEST EDITION (for General

Installation and Gas Plumbing).

The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be removed from the floor area that the dryer is to rest on.

IMPORTANT: “The dryer must be installed on noncombustible floors only.”

The dryer must not be installed or stored in an area where it will be exposed to water or weather.

The dryer is for use in noncombustible locations.

8

Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply Requirements section).

Clearance provisions must be made from noncombustible construction as noted in this manual (refer to Dryer Enclosure

Requirements section).

Even though a 12-inch clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately 2 feet away from the nearest obstruction, i.e., wall, for ease of installation, maintenance, and service. (Refer to the illustration below.)

Provisions must be made for adequate clearances for servicing and for operation as noted in this manual (refer to

Dryer Enclosure Requirements section).

Dryer must be exhausted to the outdoors in an area where correct exhaust venting can be achieved as noted in this manual (refer to Exhaust Requirements section).

Dryer must be located in an area where correct exhaust venting can be achieved as noted in this manual (refer to Exhaust

Requirements section).

The dryer must be installed with a proper exhaust duct connection to the outside.

The dryer must be installed with provisions for adequate combustion and make-up air supply.

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every six months, inspect the exhaust ducting and remove any lint build up.

IMPORTANT: Dryer must be installed in a location/ environment, which the ambient temperature remains between 40° F (4.44° C) and 130° F (54.44° C).

IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary.

Maytag Co.

113062 - 17

Dryer Enclosure Requirements _______

Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of 12-inches

(18-inches or more is recommended for ease of installation, maintenance, and service) above the dryer outer top, except along the front of the dryer, which may be closed in if desired.

NOTE: Even though a minimum of 12-inches above the dryer outer top is acceptable, a clearance of 18-inches (or more) is suggested for ease of installation and service

(electrical power connections).

When fire sprinkler systems are located above the dryers, a minimum of 12-inches above the dryer outer top is required.

Allowances must be made for opening the control door.

Dryers may be positioned sidewall to sidewall. However, allowances must be made for opening and closing of the control door and the lint door. It is suggested that the dryer be positioned about 2 feet away from the nearest obstruction for ease of installation, maintenance, and service (to be measured from the back guard.) Refer to the illustration on the previous page for details.

NOTE: Air considerations are important for proper and efficient operation.

Fresh Air Supply Requirements _______

Air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An unrestricted source of 840 cfm is necessary for each dryer. An unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet is required for each dryer. This area must be enlarged if louvers or registers cover the opening. 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 the dryers. For example, for a bank of eight dryers, a total make-up air opening of 12 square feet is required. Two openings measuring 2 feet by 3 feet (6 square feet) are acceptable. (Refer to the illustration on the this page.)

Allowances must be made for remote or constricting passageways or where dryers are located at excessive altitudes or predominantly low-pressure areas. The dryer must be installed with provisions for adequate combustion and make-up air supply.

IMPORTANT: Make-up air must be provided from a source 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.

IMPORTANT: Make-up air openings should not be located near ductwork exhaust outlets. If make-up air openings are too close to the exhaust outlet, lint and fumes may be drawn back into the dryer area through these openings.

NOTE: Component failure due to dry cleaning 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, overheating of the dryer, and shutdown of the burner by the airflow (sail) switches, burner hi-limits, or tumbler hi-heat thermostats. The dryer must be installed with a proper exhaust duct connection to the outside.

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 exhaust 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. When single dryer venting is used, the ductwork from the dryer to the outside exhaust outlet must not exceed 10 feet. In the case of multiple (common) dryer venting, the distance from the last dryer to the outside exhaust outlet must not exceed 20 feet. The shape of the exhaust ductwork is not critical so long as the minimum cross-sectional area is provided.

Single Dryer Venting

When possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust 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. It is suggested that the use of 90° turns in ducting be avoided; use 30° or 45° angles instead. The shape of the exhaust ductwork is not critical so long as the minimum cross-sectional area is provided.

IMPORTANT: Exhaust back pressure measured by a manometer at the dryer’s exhaust duct area must be no less than 0 and must not exceed 0.3 in wc when both tumblers are operating.

113062 - 17 Maytag Co.

9

It is suggested that the ductwork from each dryer not exceed

10 feet with no more than two elbows. If the ductwork exceeds

10 feet or has numerous elbows, the cross-sectional area of the ductwork must be increased in proportion to length or number of elbows in it.

IMPORTANT: For extended ductwork runs, the crosssectional area of the ductwork can only be increased to an extent. Maximum proportional ductwork runs cannot exceed 10 feet more than the original limitations of 10 feet with two elbows. When the ductwork approaches the maximum limits as noted in this manual, a professional

HVAC firm should be consulted for proper venting information.

The ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be connected. All ductwork joints must be taped to prevent moisture and lint from escaping into the building. Also, inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning.

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

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

The duct must be centered within this opening.

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 (0.0195-inches [0.50 mm]) thick.”

To protect 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 exhaust 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 nearest obstruction.

NOTE: In situations where a 10-inch exhaust duct is required or acceptable, to ease installation an 8-inch dryer exhaust outlet size to 10-inch exhaust duct increaser

(transition piece) is available from the factory by ordering

Part No. 882099.

Multiple Dryer (Common) Venting

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 45° in the direction of the airflow.

IMPORTANT: No more than eight dryers should be connected to one main common duct.

NOTE: Refer to the illustration on the next page for examples of multiple dryer (common) venting.

The main duct may be any shape so long as the minimum cross-sectional area is provided. The illustration on the next page shows the minimum cross-sectional area for multiple dryer venting. These figures must be increased in proportion if the main duct run from the last dryer to where it exhausts to the outdoors is unusually long (over 20 feet) or has numerous elbows (more than one) in it.

IMPORTANT: For extended ductwork runs, the crosssectional area of the ductwork can only be increased to an extent. Maximum proportional ductwork runs cannot exceed 20 feet more than the original limitations of 20 feet with one elbow. When the ductwork approaches the maximum limits as noted in this manual, a professional

HVAC firm should be consulted for proper venting information.

Exhaust back pressure measured by a manometer at the dryer’s exhaust duct area must be no less than 0 and must not exceed 0.3 in wc when both tumblers are operating.

The ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be connected. All ductwork joints must be taped to prevent moisture and lint from escaping into the building. Also, inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning.

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

The duct must be centered within this opening.

To protect 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 exhaust 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 nearest obstruction.

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

L.P. Gas

Dryers made for use with L.P. gas have the gas valve’s internal pressure regulator blocked open so that the gas pressure must be regulated upstream of the dryer. The pressure measured at each gas valve pressure tap must be a consistent 10.5 in wc. There is no regulator or regulation provided in an L.P. dryer. The water column pressure must be regulated at the source (L.P. tank) or an external regulator must be added to each dryer.

Piping Connections

All components/materials must conform to National Fuel Gas

Code Specifications ANSI Z223.1-LATEST EDITION, or in

Canada, CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-

B149.2-M91 (L.P. Gas) or LATEST EDITION (for General

Installation and Gas Plumbing), as well as local codes and ordinances and must be done by a qualified professional. It is important that gas pressure regulators meet applicable pressure requirements, and that gas meters be rated for the total amount of all the appliance Btu being supplied.

The dryer is provided with a 3/4” N.P.T. inlet pipe connection at the upper right hand corner (when viewed from the rear) of each dryer. It is recommended that a gas shutoff valve be provided to the gas supply line of each dryer for ease of servicing.

The size of the main gas supply line (header) will vary depending on the distance this line travels from the gas meter

(or in the case of L.P. gas, the supply tank), the number of tees, other gas-operated appliances on the supply line, etc.

Specific information regarding supply line size should be determined by the gas supplier.

NOTE: Undersized gas supply piping can create a low or inconsistent pressure, which will result in erratic operation of the burner ignition system.

Consistent gas pressure is essential at all gas connections.

It is recommended that a 3/4” pipe loop be installed in the supply line servicing the bank of dryers. An in-line pressure regulator must be installed in the gas supply line (header) if

(natural) gas line pressure exceeds 12.0 in wc pressure.

(Refer to the illustration below for details.)

IMPORTANT: Water column pressure of 3.5 inches for natural gas dryers and 10.5 inches for L.P. gas is required at the gas valve pressure tap of each dryer for proper and safe operation.

A 1/8” N.P.T. plugged tap, accessible for a test gauge connection, must be installed in the main gas supply line immediately upstream of each dryer.

IMPORTANT: Pipe joint compounds that resist the action of natural gas and L.P. gas must be used.

▲ WARNING

Fire Hazard

Test all connections for leaks by brushing on a soapy water solution (liquid detergent works well).

Never test for leaks with a flame!!!

It is important that gas pressure regulators meet applicable pressure requirements and that gas meters be rated for the total amount of appliance Btu being supplied.

Preparation for Operation _____________

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

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

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

• GAS MODELS – check to assure that the dryer is connected to the type of heat or gas indicated on the dryer data label.

• The sail switch damper assembly was installed and adjusted at the factory prior to shipping. However, each sail switch adjustment must be checked to assure that this important safety control is functioning.

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

• GAS MODELS – be sure that all gas shutoff valves are in the open position.

• Be sure all back guard panels and service box covers have been replaced.

• Check the lint door to assure that it is closed and secured in place.

• Rotate the tumbler by hand to be sure it moves freely.

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.

Coin Models Only

The display will read “0 minutes” for both tumblers and the price required to start a cycle.

Insert the proper number of coins into coin acceptor. Once the correct amount needed to start the dryer has been inserted, the L.E.D. display will read “SELECT CYCLE.”

14

Start the dryer by pressing the desired fabric setting. After the cycle is started, drying time will count down whether the door is closed or open.

NOTE: The dryer can be stopped at any time by opening the main door. To restart dryer, shut the main door and press desired fabric setting.

Open main door to stop the dryer, and change to a different fabric setting. Repeat this procedure, until all fabric selections have been tested. This will also confirm that setting key circuits and door switch circuits are functioning properly.

Repeat above procedure for the other tumbler.

Heat Circuit Operational Test

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.

Gas dryers are equipped with a DSI system, which has internal diagnostics. If ignition is not established after the first attempt, the heat circuit in the DSI module will lockout until it is manually reset. To reset the DSI system, open and close the main door and restart the dryer.

Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the water column pressure is correct and consistent.

NOTE: Water column pressure requirements (measured at the pressure tap of the gas valve body):

Natural Gas .... 3.5 in wc

L.P. Gas .......... 10.5 in wc

IMPORTANT: There is no regulator provided in an L.P.

dryer. The water column pressure must be regulated at the source (L.P. tank) or an external regulator must be added to each dryer.

Make a complete operational check of all the operating controls to ensure that the timing is correct and that the temperatures are set properly.

Make a complete operational check of all safety related circuits

(i.e., door switches, hi-limit thermostats, sail switches, tumbler safety thermostats, etc.).

NOTE: The sail switch can be checked for proper operation by leaving the control door open and inserting the lint screen then starting the dryer. The heating unit(s) should not activate. If the heating unit does activate, make the necessary adjustments.

Each tumbler should be operated through one complete cycle to assure that no further adjustments are necessary and that all components are functioning properly.

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.

Computer Programs and Selections

Each microprocessor controller (computer) has been preprogrammed by the factory with the most commonly used program (parameter) selections. If microprocessor controller

(computer) program changes are required, refer to the computer programming manual, which was shipped with the dryer.

Shutdown Instructions ________________

In the case where 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 gas supply (for gas models only):

Shut off external gas supply shutoff valve.

Shut off internal gas supply shutoff valve located in the gas valve burner area (for both the top tumbler and the bottom tumbler).

Operating Instructions ________________

Starting the Dryer

The dryer is available for use when the appropriate side of the microprocessor display reads “0 minutes” and the amount needed to start the dryer (i.e., “25”). Once the load has been put into the dryer and the main door is closed, start the dryer as follows:

Insert the proper number of coins into the coin acceptor. Once the correct “Amount To Start” has been inserted, the display will read “SELECT CYCLE.”

Determine fabric setting (selection).

Once the fabric temperature setting (selection) has been determined, start the dryer by pressing the fabric setting key.

The dryer will now start, and the display will read the setting and the time vended.

The cycle time will count down until the drying and cooling cycles are completed.

Upon completion of the drying and cooling cycles, the dryer will shut off.

Notes

The dryer tumbler can be stopped at any time by opening the main door. To restart dryer, shut the main door and press desired setting.

NOTE: When a cycle is interrupted by opening the main door, cycle time will continue to count downward, regardless if the door is open or closed.

Selection (setting) changes can be made at any time during the drying cycle.

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 air circulation. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, a Maytag dryer will provide many years of efficient, trouble free and most importantly safe operation.

▲ WARNING

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

▲ WARNING

Fire Hazard

The accumulation of lint in the exhaust ductwork can create a potential fire hazard.

Do not obstruct the flow of combustion air and ventilation air.

Fire Hazard

Lint from most fabrics is highly combustible. The accumulation of lint can create a potential fire hazard.

Keep dryer area clear and free from combustible materials, gasoline, and other flammable vapors and liquids.

Inspect and remove lint accumulation from the dryer’s exhaust ductwork back draft dampers.

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

NOTE: Suggested time intervals shown are for average usage, which is considered six to eight operational

(running) hours per day.

IMPORTANT: Dryer produces combustible lint and must be exhausted to the outdoors. Every six months, inspect the exhaust ducting and remove any lint build up.

Suggested Cleaning Schedule

Daily (beginning of each work shift)

Clean lint from lint drawer and screen assembly.

Inspect lint screens or drawers for damage and replace if torn.

Every 6 Months

In the cleaning of the dryer cabinet, avoid using harsh abrasives. A product for the cleaning of appliances is recommended.

All bearings and setscrews should be checked to ensure they are tight.

Adjustments

7 Days After Installation and Every 12 Months Thereafter

Inspect bolts, nuts, screws (bearing setscrews), grounding connections, nonpermanent gas connections (unions, shutoff valves, and orifices), and electrical terminations. Motor and drive belts should be examined. A cracked or seriously frayed belt should be replaced. Tighten loose belts when necessary and check the alignment. Complete operational check of controls and valves. Complete operational check of all safety devices (door switches, lint compartment switches, sail switches, burner and hi-limit thermostats).

Weekly

Clean lint accumulation from around microprocessor temperature sensor probes and sensor bracket assemblies.

90 Days

Remove lint from the motor air vents and surrounding area.

IMPORTANT: Lint accumulation will restrict the airflow over the motors, causing overheating and irreparable motor damage. Motor failure due to lint accumulation will void the warranty.

Remove lint accumulation from around the openings in the dryer’s back panels.

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

Remove any lint accumulation from the coin acceptor area, including the optical switch.
