IMPORTANT INFORMATION

A. 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/or packaging, and wooden skid should be visually inspected for shipping damage. If any damage whatsoever 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.

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

3. 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.

4. 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 (2) passes after the freight was delivered. It is your responsibility to file freight claims. Dryer/parts damaged in transit cannot be claimed under warranty.

5. Freight claims are the responsibility of the consignee, and ALL claims must be filed at the receiving end. ADC assumes no responsibility for freight claims or damages.

1) Remove the eight (8) sets of nuts and washers F holding the console (module) to the base.

IMPORTANT: The dryer must be transported and handled in an upright position at ALL times.

C. DRYER ENCLOSURE REQUIREMENTS

Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately two (2) feet (24-inches) - 0.61 meters (60.96 cm) - from the nearest obstruction (i.e., wall) for ease of installation, maintenance, and service. Bulkheads and partitions should be made from noncombustible materials. The clearance between the bulkhead header and the dryer must be a minimum of 4- inches (10.16 cm) and must not extend more than 4-inches (10.16 cm) to the rear of the front. The bulkhead facing must not be closed in ALL the way to the top of the dryer. A 2-inch (5.08 cm) clearance is required.

NOTE: Bulkhead facing should not be installed until after the dryer is in place. Ceiling area must be

located a minimum of 12-inches (30.48 cm) above the top of the dryer.

IMPORTANT: Even though a minimum of only 12-inches (30.48 cm) is required, 18-inches (45.72

cm) or more is suggested, for steam dryers and especially in cases where sprinkler heads are over the dryers.

NOTE: When fire sprinkler systems are located above the dryers, a minimum of 18-inches (45.72 cm)

above the dryer console (module) is suggested. Dryers may be positioned side wall to side wall, however, 1 or 2-inches (2.54 or 5.08 cm) is suggested for ease of installation and maintenance. Allowances must be made for the opening and closings of the control door and the lint door.

D. FRESH AIR SUPPLY REQUIREMENTS

When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler (basket), 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 switch fluttering problems may result, as well as premature motor failure from overheating.

Air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An unrestricted source of air is necessary for each dryer. An airflow of 1,750 cfm (cubic feet per minute) - 49.55 cmm - must be supplied to each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 300 square inches (1935.48 square centimeters) is required for each dryer.

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

is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are

It acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to ALL the dryers.

EXAMPLE: For a bank of six (6) dryers, two (2) unrestricted openings measuring 36-inches

by 25-inches (1800 square inches) - 91.44 cm by 63.5 cm (11612.88 square centimeters) is acceptable.

will be adversely affected. Ignition problems and sail

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

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.

NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.

E. EXHAUST REQUIREMENTS

1. General Exhaust Duct Work Information

Exhaust duct work should be designed and installed by a qualified professional. Improperly sized duct work will create excessive back pressure which results in slow drying, increased use of energy, overheating of the dryer, and shut down of the burner by the airflow (sail) switches, burner hi-limits, or tumbler (basket) hi-heat thermostats.

CAUTION: DRYER MUST BE EXHAUSTED TO THE OUTDOORS.

CAUTION: IMPROPERLY SIZED or INSTALLED EXHAUST DUCT WORK CAN

CREATE A POTENTIAL FIRE HAZARD.

NOTE: When a dryer is exhausted separately, it is recommended that a back draft damper be

installed.

NOTE: When dryers are exhausted into a multiple (common) exhaust line, each dryer must be

supplied with a back draft damper.

The duct work should be laid out in such a way that the duct work travels as directly as possible to the outdoors with as few turns as possible. Single or independent dryer venting is recommended. When single dryer venting is used, the duct work from the dryer to the outside exhaust outlet should not exceed 20 feet (6.09 meters). In the case of multiple (common) dryer venting, the distance from the last dryer to the outside exhaust outlet should not exceed 20 feet (6.09 meters). The shape of the duct work is not so critical so long as the minimum cross-sectional area is provided. It is suggested that the use of 90º turns be avoided; use 30º and/or 45º bends/angles instead. The radius of the elbows should preferably be 1-1/2 times the diameter of the duct. Excluding tumbler (basket)/dryer elbow connections or elbows used for outside protection from the weather, no more than three (3) elbows should be used in the exhaust duct run. If more than three (3) elbows are used, the cross-sectional area of the duct work must be increased in proportion to the number of elbows used.

ALL duct work 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 duct work joints must be taped to prevent moisture and lint from escaping into the building. Inspection door should be installed at strategic points in the exhaust duct work for periodic inspection and clean-out of lint from the duct work.

IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct should not

exceed 0.3 inches of water column (0.74 mb).

NOTE: Where the exhaust duct work passes through a wall, ceiling, or roof made of combustible

materials, the opening must be 2-inches (5.08 cm) larger (all the way around) than the duct. The duct must be centered within this opening.

a. Outside Duct Work Protection

1) To protect the outside end of horizontal duct work from the weather, a 90° elbow bent downward

should be installed where the exhaust exits the building. If the duct work 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.

IMPORTANT: DO NOT use screens or caps on the outside of opening of exhaust duct work.

2. Single Dryer Venting

Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust duct should be laid out in such a way that the duct work travels as directly as possible to the outdoors with as few turns as possible. It is suggested that the use of 90° turns in the ducting be avoided; use 30° and/or 45° angles instead. The shape of the exhaust duct work is not critical so long as the minimum cross section area is provided.

IMPORTANT: Minimum duct size for a dryer is 12-inches (30.48 cm) for a round duct 10-3/4 x

10-3/4 (27.31 cm x 27.31 cm) for a square duct. THE DUCT SIZE MUST NOT

BE REDUCED ANYWHERE DOWN STREAM OF THE DRYER.

IMPORTANT: Exhaust back pressure measured by a manometer at each tumbler (basket) exhaust

duct area should not exceed 0.3 inches of water column (0.74 mb).

It is suggested that the duct work from each dryer (minimum of 12-inches [30.48 cm] for a single dryer) not exceed 15 feet (4.57 meters) with no more than three (3) elbows (including dryer connection). If the duct

work exceeds 15 feet (4.57 meters) or has numerous elbows, the cross-sectional area of the duct work must be increased in proportion to the length and number of elbows in it. In calculating duct size, the crosssectional area of a square or rectangular duct must be increased twenty percent (20%) for each additional 20 feet (6.09 meters). The diameter of a round exhaust duct should be increased ten percent (10%) for each additional 15 feet (4.57 meters). Each 90º elbow is equivalent to an additional 30 feet (9.14 meters), and each 45º elbow is equivalent to an additional 15 feet (4.57 meters).

IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be

increased to an extent. When the duct work approaches the maximum limits as noted in this manual, a professional heating venting air conditioning (HVAC) firm should be consulted for proper venting information.

ALL duct work 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 duct work joints must be taped to prevent moisture and lint from escaping into the building. Inspection doors should be installed at strategic points in the exhaust duct work for periodic inspection and clean-out of lint from the duct work.

NOTE: Where the exhaust duct passes through a wall, ceiling, or roof made of combustible materials,

the opening must be 2-inches (5.08 cm) larger (all the way around) than the duct. The duct must be centered within this opening.

a. Outside Duct Work Protection

1) To protect the outside end of horizontal duct work from the weather, a 90° elbow bent downward

IMPORTANT: DO NOT use screens or caps on the outside of opening of exhaust duct work.

3. 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 flow and should be spaced at least 48-3/4 inches (123.83 centimeters) apart. The main duct should be tapered with the diameter increasing before each individual 12-inch (30.48 cm) - minimum for each dryer - duct is added.

IMPORTANT: The ML-130DR is not provided with a back draft damper. When exhausted into a

multiple (common) exhaust line, a back draft damper must be installed at each dryer duct.

IMPORTANT: No more than four (4) dryers should be connected to one (1) main common duct.

The main duct may be any shape or cross-sectional area, so long as the minimum cross section area is provided. The illustration on the bottom of page 19 shows the minimum cross section area for multiple dryer round or square venting. These figures must be increased 10 square inches (64.52 square centimeters) when rectangular main ducting is used, and the ratio of duct width to depth should not be greater than 31/2 to 1. These figures must be increased in proportion if the main duct run to the last dryer to where it exhausts to the outdoors is unusually long (over 20 feet [6.09 meters]) or has numerous elbows (more than two [2]) in it. In calculating duct work size, the cross-sectional area of a square or rectangular duct must be increased twenty percent (20%) for each additional 20 feet (6.09 meters). The diameter of a round exhaust must be increased ten (10) percent for each additional 20 feet (6.09 meters). Each 90° elbow is equivalent to an additional 30 feet (9.14 meters) and each 45° elbow is equivalent to an additional 15 feet (4.57 meters).

IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be

increased to an extent. Maximum proportional duct work runs cannot exceed 20 feet (6.09 meters) more than the original limitations of 20 feet (6.09 meters) with two (2) elbows. When the duct work approaches the maximum limits as noted in this manual, a professional heating venting air conditioning (HVAC) firm should be consulted for proper venting information.

IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct should not

exceed 0.3 inches of water column (0.74 mb).

The duct work 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. building.

9. Rotate the tumbler (basket/drum) by hand to be sure it moves freely.

10. Check bolts, nuts, screws, terminals, and fittings for security.

11. Check tumbler bearing set screws to insure they are ALL tight.

I. PREOPERATIONAL TESTS

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.

1. Turn on electric power to the dryer.

2. Make sure the main door is closed and the lint drawer is securely in place.

3. Refer to the Operating Instructions for starting your particular model dryer.

4. Check to insure that the tumbler (basket) starts in the clockwise (CW) direction. Additionally, check the direction of the blower motor impellor (fan) to insure that the impellor (fan) rotates in the clockwise (CW) direction as viewed from the front. If it is, the phasing is correct. If the phasing is incorrect, reverse two (2) of the leads at L1, L2, or L3 of the power supply connections made to the dryer.

IMPORTANT: Dryer blower motor impellor/fan as viewed from the front must turn in the clockwise

(CW) direction, otherwise the dryer efficiency will be drastically reduced and premature component failure can result.

5. Heat Circuit Operational Test

a. Gas Models

1) When the dryer is first started (during initial start-up), the burner has a tendency not to ignite on the first attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for this air to be purged from the lines.

2) The dryer is equipped with a Hot Surface Ignition (HSI) system which has internal diagnostics. If ignition is not established after three (3) attempts, the heat circuit HSI module will LOCKOUT until it is manually reset. To reset the HSI system, open and close the main door and restart the dryer (press the ENTER/START key).

NOTE: During the purging period, check to be sure that ALL gas shut-off valves are open.

3) 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 (W.C.) pressure is correct and consistent.

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

Natural Gas ---- 3.5 Inches W.C. (8.7 mb). L.P. Gas-------- 10.5 Inches W.C. (26.1 mb).

IMPORTANT: There is no regulator provided in an L.P. dryer. The water column (W.C.) pressure

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

6. Make a complete operational check of ALL safety-related circuits (i.e., lint drawer switch, and sail switch

on gas models).

NOTE: To check for proper sail switch operation, open the main door and while holding main door

switch plunger in, start the dryer. The dryer should start but the heat circuit should not be activated (on). If the heat (burner) does activate, shut the dryer off and make the necessary adjustments.

7. A reversing tumbler (basket) dryer should never be operated with less than a 60 lb. (2.72 kg) load (dry

weight). The size of the load will affect the coast-down and dwell (stop) times. The tumbler (basket) must come to a complete stop before starting in the opposite direction.

a. Microprocessor (computer) Dryer Models

1) Spin and stop are not adjustable in the Automatic Mode and have been preprogrammed into the microprocessor controller (computer) for 150-seconds spin time in the forward direction and 120-seconds in the reverse direction with a 5-second dwell (stop) time.

2) Spin and stop times are adjustable in the Manual (timed) Mode.

b. Dual Timer Dryer Models

1) Both spin time and stop (dwell) time are adjustable (refer to

page 36).

BASKET COATING The tumbler (basket) is treated with a protective coating. We suggest dampening old garments or cloth material with a solution of water and non-flammable mild detergent and tumbling them in the tumbler (basket) to remove this coating.

8. Each dryer should be operated through one (1) complete cycle to assure that no further adjustments are necessary and that ALL components are functioning properly.

9. Make a complete operational check of ALL operating controls.

a. Microprocessor controller (computer) programs/selections...

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

b. Dual Timer check...

1) Heating Timer

2) Cool Down Timer

SECTION VI

ROUTINE MAINTENANCE

A. 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 duct work 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, an ADC dryer will provide many years of efficient, trouble-free, and - most importantly - safe operation.

WARNING: LINT FROM MOST FABRICS IS HIGHLY COMBUSTIBLE. THE

ACCUMULATION OF LINT CAN CREATE A POTENTIAL FIRE HAZARD.

WARNING: KEEP DRYER AREA CLEAR and FREE FROM COMBUSTIBLE

MATERIALS, GASOLINE, and OTHER FLAMMABLE VAPORS and LIQUIDS.

NOTE: REMOVE POWER FROM THE MACHINE BEFORE PERFORMING ANY

MAINTENANCE IN THE MACHINE (cleaning the lint drawers and lint screens are the only exceptions).

NOTE: Suggested time intervals shown are for average usage which is considered six (6) to eight (8)

operational (running) hours per day.

CLEAN LINT FROM LINT DRAWER/SCREEN EVERY THIRD or FOURTH LOAD.

NOTE: The frequency of cleaning the lint screens can best be determined from experience at each

location.

WEEKLY

Clean lint accumulation from the lint chamber, thermostat, and microprocessor temperature sensor (sensor bracket) area.

WARNING: TO AVOID HAZARD OF ELECTRICAL SHOCK, DISCONTINUE

ELECTRICAL POWER SUPPLY TO THE DRYER.

90 DAYS

Remove lint from around tumbler (basket), drive motors, and surrounding areas. Remove lint from the gas valve burner area with a dusting brush or vacuum cleaner attachment.

NOTE: To prevent damage, avoid cleaning and/or touching the Hot Surface Ignitor.

Remove lint accumulation from inside the control box and at rear area behind the control box.

Impellor (fan/blower) shaft bearings should be lubricated using Shell Alvania grease NLGI 2 or its equivalent. Generically, this grease would be described as an NLGI grade 2 multipurpose industrial grease with a lithium thickener and mineral base oil.

6 MONTHS

Inspect and remove lint accumulation in customer furnished exhaust duct work system and from dryers internal exhaust ducting.

NOTE: THE ACCUMULATION OF LINT IN THE EXHAUST DUCT WORK CAN

CREATE A POTENTIAL FIRE HAZARD.

NOTE: DO NOT OBSTRUCT THE FLOW OF COMBUSTION and VENTILATION AIR.

CHECK CUSTOMER FURNISHED BACK DRAFT DAMPERS IN THE EXHAUST DUCT WORK. INSPECT and REMOVE ANY LINT ACCUMULATION WHICH CAN CAUSE THE DAMPER TO BIND or STICK.

NOTE: A back draft damper that is sticking partially closed can result in slow drying and shut down of

the heat circuit safety switches or thermostats.

NOTE: When cleaning the dryer cabinet(s), avoid using harsh abrasives. A product intended for the

cleaning of appliances is recommended.

B. ADJUSTMENTS

7 DAYS AFTER INSTALLATION and EVERY 6 MONTHS THEREAFTER

Inspect bolts, nuts, screws, (bearing set screws), nonpermanent gas connections (i.e., unions, shut-off valves, orifices), and grounding connections. Fan (impellor) V-belts, along with the motor and drive chains should be examined and replaced if necessary. Tighten loose V-belts when necessary. Complete operational check of controls and valves. Complete operational check of ALL safety devices (i.e., door switches, lint drawer switch, sail switch, burner and hi-limit thermostats).

C. LUBRICATION

The fan shaft bearings should be lubricated every three (3) months. Use Shell Alvania grease NLGI grade 2 or its equivalent. Generically, this grease would be described as an NLGI grade 2 multipurpose industrial grease with a lithium thickener and mineral base oil. Lubrication is necessary. The motor bearings...and under normal/ most conditions the tumbler bearings are permanently lubricated. It is physically possible to re-lubricate the tumbler bearings if you choose to do so even though this practice may not be necessary. Use Shell Alvania grease NLGI grade 2 or its equivalent. Generically, this grease would be described as an NLGI grade 2 multipurpose industrial grease with a lithium thickener and mineral base oil. The tumbler bearings used in the dryer DO NOT have a grease fitting. Provisions are made in the bearings housing for the addition of a grease fitting which can be obtained elsewhere, or from ADC by ordering kit P/N 882159 (includes 2 fittings).

PROCEDURE FOR FUNCTIONAL CHECK

OF REPLACEMENT COMPONENTS

1. Microprocessor (computer) Board

a. Upon completing installation of the replacement microprocessor (computer) board, reestablish power to

the dryer.

b. Start the drying cycle by pressing any of the preset cycles in letters A-F.

c. Verify that the motor(s) and the heat indicator dots, in the microprocessor (computer) L.E.D. (light

emitting diode) display are on. (Refer to the illustration below.)

1) Tumbler (Basket) in Forward Mode (clockwise [CW]) indicator

2) Tumbler (Basket) in Reverse Mode (counterclockwise [CCW]) indicator

3) Heat on indicator

4) On indicator (dryer is in Operation Mode)

5) Air Jet indicator

d. Verify that the motor(s) heat, and door indicator lights on the back side of the microprocessor (computer)

board are lit. (Refer to the illustration below.)

1) FAN (Blower) L.E.D. indicator

2) FOR (Forward) output L.E.D. indicator

3) Rev (Reverse) output L.E.D. indicator

4) Air (Air Jet) output L.E.D. indicator

5) HT 1 (Heat) output L.E.D. indicator

6) Fuse (Main Fuse) input L.E.D. indicator

7) Lint (Lint Door) input L.E.D. indicator

8) Main (Main Door) input L.E.D. indicator

9) Drum (Tumbler [Basket] Hi-Limit) input L.E.D. indicator

10) Sail (Sail Switch) input L.E.D. indicator

11) Burn (Burner Hi-Limit) input L.E.D. indicator

12) Flame (Burner Control Failure) input L.E.D. indicator

13) Power Supply

e. Open main door. The dryer must stop and

(light emitting diode) display must go out. (Refer to illustration on page 37.)

f. Try to restart the dryer with the main door open.

g. The microprocessor (computer) boards L.E.D. display must read MAIN dOOR.

h. Close the main door and restart the dryer.

i. Functional check of microprocessor (computer) board is complete.

2. Hot Surface Ignition (HSI) System

a. Upon completing installation of the

replacement Hot Surface Ignition (HSI) module, reestablish power to the dryer.

b. The HSI modules red indicator

light will light for up to approximately 5-seconds (self check routine).

ALL indicator dots of the microprocessor (computer) L.E.D.

If the HSI modules red indicator light stays on or flashes continuously, then the HSI module is wired incorrectly or has failed.

c. Start the drying cycle.

d. The hot surface ignitor will turn on, and a few seconds later the gas valve

approximately 4-seconds the hot surface ignitor will shut off. Ignition (flame) should now be established.

e. With the burner flame on, remove the flame sensor wire from the S2 terminal of the HSI module. The

burner flame must shut off immediately.

f. Stop the drying cycle, with the flame sensor wire still removed, restart the drying cycle.

g. The hot surface ignitor will turn on, and after a few seconds later the gas valve will be energized and the

hot surface ignitor will shut off. Ignition (flame) should be evident for approximately 7-seconds and then shut off.

h. The HSI module will attempt two (2) additional ignition trials after which the HSI module will lockout and

the red indicator light will flash continuously.

will be energized. After

i. Functional check of the Hot Surface Ignition (HSI) Module is complete.

1) Replace the flame sensor wire from the S2 terminal to the HSI module.

SECTION IX

BURNER and LINT (TUMBLER) CHAMBER MANUAL RESET HI-LIMIT INSTRUCTIONS

(FOR PHASE 6 MODELS)

This dryer was manufactured with a manual reset burner hi-limit (gas models only) and tumbler/lint chamber hi-limit thermostat which is monitored by the Phase 6 computer. If either manual reset thermostat is open prior to start of the drying cycle, the dryer will start momentarily and then shut down, the Phase 6 computer will display an error code with an audio indication. If the tumbler/lint chamber hi-limit thermostat is open, the display will read dRUM SAFETY FAIL. If the burner hi-limit thermostat is open, the display will read bURNER SAFETY FAIL.

If either manual reset hi-limit thermostat opens during a drying cycle, the display will show the applicable error code described above along with an audio indication. If the drum temperature is above 100º F (38º C), the dryer will continue to run with no heat for three (3) minutes or until the drum temperature has flattened below 100º F (38º C). The clear/stop button on the Phase 6 keyboard (touchpad) must be pressed to clear the error condition. The open manual reset hi-limit thermostat must be reset manually prior to the start of the next cycle.

This hi-temperature condition may be caused due to a restricted exhaust, poor airflow or improper burner operation.

The location of the burner hi-limit is on the right side of the burner box and the tumbler hi-limit is located in the lint chamber area.

WARNING: Discontinue power to dryer before attempting to reset hi-limit.

IMPORTANT

This dryer is equipped with a burner hilimit and tumbler/lint chamber hi-limit thermostat which must be reset manually.

WARNING: Discontinue power to dryer before attempting to reset hi-limit.
