Failure to install, maintain, and/or operate this machine according to the manufacturer’s instructions may result in conditions which can produce serious injury, death and/or property damage.

It must be understood that common sense, caution and carefulness are factors which cannot be built into this tumbler. These factors MUST BE supplied by the person(s) installing, maintaining or operating the tumbler.

Always contact your dealer, distributor, service agent or the manufacturer on any problems or conditions you do not understand.

To reduce the risk of fire, electrical shock, serious injury or death to persons do not operate the tumbler if it does not perform according to these instructions. Immediately disconnect electrical service, shut off gas supply and contact an authorized service representative. Service and repairs are to be performed by authorized service representatives only.

To reduce the risk of fire, electrical shock, serious injury or death to persons when using the tumbler unit, follow these basic precautions:

• Read all instructions before using tumbler.

• DO NOT tamper with controls.

• DO NOT bypass any safety devices.

• Always follow the fabric care instructions supplied by the garment manufacturer.

• Remove laundry immediately after the tumbler stops.

• DO NOT reach into tumbler if cylinder is revolving.

To avoid creating any flammable vapors which may explode, ignite or cause corrosive damage, DO NOT dry the following materials:

• Articles that have been cleaned in, soaked in, washed in or spotted with gasoline, dry cleaning solvents or other flammable/explosive substances.

• Plastics or articles containing foam rubber or similarly textured rubberlike materials.

• Articles that have traces of flammable substances like cooking oil, machine oil, flammable chemicals or thinner.

• Articles containing wax or cleaning chemicals.

• Fiberglass curtains or draperies (unless the label says it can be done).

Do not allow children to play on or in the tumbler. Close supervision of children is necessary when the tumbler is used near children. This is a safety rule for all appliances.

Before the tumbler is removed from service or discarded, remove the door to the drying compartment.

Always disconnect the electrical power to the tumbler before servicing. Disconnect power by shutting off the appropriate circuit breaker or fuse and by turning off the disconnect switch located on the rear of the tumbler.

All manually operated models are factory-equipped with an emergency stop button located on the front panel. If the emergency stop function is desired on coin-operated models, an external emergency stop switch may be installed as specified on the machine wiring diagram.

NOTE: Activation of the emergency stop switch stops all machine control circuit functions, but does not remove all electrical power from the machine.

Upon delivery, visually inspect the crate, carton, and parts for any visible shipping damage. If there are signs of possible damage, have the carrier note the condition on the shipping papers before signing, or advise the carrier of the condition as soon as it is discovered.

Remove the crate and protective cover as soon as possible and check items listed on the packing list.

Advise the carrier of any damaged or missing articles as soon as possible. A written claim should be filed with the carrier immediately if articles are damaged or missing.

IMPORTANT: Remove shipping tape from the two back draft dampers located in the exhaust thimble.

The following materials should be obtained locally:

For Gas, Electric, or Steam Drying Tumblers:

• One circuit breaker.

For Gas Drying Tumblers Only:

• One gas shut-off valve for the gas service line to each tumbler.

For Steam Drying Tumblers Only:

• One steam shut-off gate valve for the steam service line to be connected upstream of the solenoid steam valve.

• Two steam shut-off gate valves for each condensate return line.

• Flexible steam hoses with a 125 psig (8.79 kg/sq. cm) working pressure for connecting steam coils.

• Two steam traps for the steam coil outlet to the condensate return line.

• One steam pressure relief valve rated at 125 psig (8.79 kg/cm²).

Floor: The drying tumbler may be installed on any level floor capable of supporting 100 pounds per square foot (488 kg/m²). Floor covering materials such as carpeting or tile should be removed.

Layout: Whenever possible, the tumbler should be installed along an outside wall where duct length can be kept to a minimum, and make-up air can be easily accessed. Construction must not block airflow at the top rear of the tumbler, as this would prevent an adequate air supply to the tumbler’s combustion chamber.

For maximum efficiency and minimum lint accumulation, tumbler air must be exhausted to the outdoors by the shortest possible route. Proper sized exhaust ducts are essential for proper operation.

• All elbows should be sweep type. Do not install elbows with a radius less than that shown in the equivalent length table.

• Exhaust ducts must be assembled so interior surfaces are smooth to reduce the accumulation of lint. Do not use sheet metal screws to join vent sections.

• Exhaust ducts shall be constructed of sheet metal or other noncombustible material, equivalent in strength and corrosion resistance to galvanized sheet steel not less than 0.0195 inches (0.495 mm) thick.

• Where the exhaust duct pierces a combustible wall or ceiling, an opening having a diameter of 4 inches (10.2 cm) larger than the duct diameter shall be provided, with the duct centered in the opening. The space around the duct shall be sealed with non-combustible material.

• For individual venting, the cross area of the installed venting must not be less than the cross area of the exhaust thimble of the tumbler at any point.

• The maximum allowable length of venting is 14 feet (4.3 m) and two 90° elbows or equivalent. If the length exceeds this, the duct diameter must be increased.

• With the tumbler in operation, airflow at any point in the duct must be at least 1200 feet (366 m) per minute to ensure that lint remains airborne.

The table below shows how to determine the equivalent length of straight duct for 90° elbows. The total equivalent length is the sum of the straight duct length plus the equivalent length of all elbows.

Example: A 6-inch (15.2 cm) diameter duct with 14 feet (4.3 m) of straight duct and two 90° elbows has an equivalent length of 28 feet (8.5 m).

14 feet + 7 feet (for first elbow) + 7 feet (for second elbow) = 28 feet.

Equivalent Length (feet) (m) = 1.17 x Duct Diameter (inches) (cm)

While it is preferable to exhaust tumblers individually, a main collector duct may be used if sized correctly. The diameters should be increased if the collector length exceeds 20 feet (6.1 m).

• The collector duct may be rectangular, as long as the area is not reduced. Provisions should be made for lint removal and cleaning.

• The collector duct must be tapered.

• Individual tumbler ducts must enter the collector duct at a 45° angle in the direction of air flow. Never connect a tumbler duct at a 90° angle to the collector duct.

• Never connect two tumbler exhaust ducts directly across from each other at the point of entry to the collector duct.

• The collector system must be designed so static back pressure measured 12 inches (30.5 cm) from the exhaust thimble does not exceed the maximum allowable pressure specified on the installation sticker on the rear of the tumbler (measured with all tumblers running).

A tumbler has forced air exhaust and requires provisions for make-up air to replace the exhausted air. The manufacturer’s recommended make-up air opening for each 30 lb tumbler is 144 square inches (928 sq. cm).

At a minimum, tumblers must have at least 1 sq. inch (2.54 sq. cm) of opening for every 1000 BTU/hr of input rating for proper combustion.

Protective louvers in the opening to the outdoors can reduce air movement by approximately 40%. The opening must compensate for the area taken up by louvers.

Make-up air openings for a room containing tumblers and/or other gas-fired appliances must be increased sufficiently to prevent downdrafts in any vents when all tumblers are in operation. If it is necessary to duct make-up air to the tumbler, increase the area of work by 25% to compensate for any restriction in air movement.

To reduce the risk of fire and accumulation of combustible gases, DO NOT exhaust tumbler air into a window well, gas vent, chimney or enclosed, unventilated area such as an attic, wall, ceiling, crawl space under a building, or concealed space of a building.

If dry cleaning machines are in the same area as the tumbler, the tumbler make-up air must come from a source free of solvent gases and vapors. Solvent gases and vapors from dry cleaning machines create corrosive acids when drawn through the heater of a drying tumbler.

For best performance, provide an individual exhaust duct for each tumbler. It is better to have hot water heaters in a separate room with a separate air inlet.

NOTE: Do not install wire mesh or screen in the exhaust opening as lint will build up and prevent proper discharge of air from tumblers.

The minimum clearances to the nearest combustible material are as follows:

• Top: 12 inches (30.5 cm) Minimum. 0 inches is permitted for the first 4 inches (10.2 cm) along the front of the machine.

• Back: 0 inches. A minimum of 24 inches (61 cm) is recommended for service access.

• Sides: 0 inches Permitted.

All electrical connections should be made by a qualified electrician. To reduce the risk of electrical shock, de-energize the electrical circuit before making any connections.

1. Install a circuit breaker as close to the tumbler as possible. A separate circuit breaker should be provided for each tumbler.

2. Follow these steps:

a. Connect conduit-encased leads to the circuit breaker.

b. Turn “off” the disconnect switch on the tumbler and open the junction box.

c. Insert conduit-encased leads through one of the knockout holes in the junction box.

d. Connect wire leads to the disconnect switch.

• 1 Phase Units: Connect one lead to the top left connection point. Connect the other lead to the top right connection point.

• 3 Phase Units: Connect one lead to each connection point.

e. Connect a ground wire to the PE Busbar in the junction box.

3. Check the electrical service phase sequence (three-phase only).

4. Close the junction box cover and turn “on” the disconnect switch.

a. Energize the electrical service and momentarily start the tumbler. Check the direction of the cylinder rotation (viewed from the front).

b. If the cylinder rotates clockwise, the phase sequence is correct.

c. If the cylinder rotates counterclockwise, disconnect power and reverse any two leads at the connections.

Positioning:

The tumbler can be removed from its shipping skid before or after moving to the installation location. Unscrew the four shipping capscrews (one at each corner) to remove the tumbler from the skid. The lint panel door may need to be removed to access the two front capscrews. NOTE: Do not throw these four capscrews away – they are the leveling legs.

Screw the four leveling legs back into the level adjusting fittings from the top. Slide the tumbler to its permanent location. Keep the tumbler as close to the floor as possible. All four legs must rest firmly on the floor so the weight is evenly distributed and the tumbler does not rock.

Leveling:

Each tumbler should be leveled within 1/8 inch (3.2 mm) from front to rear, and 1/8 inch (3.2 mm) from side to side. Check the front-to-rear level by rotating the clothes cylinder until one rib is at the bottom, then place a level on that bottom rib. The side-to-side level should be checked by placing a level on the front and rear of the top panel.

The size of the gas service pipe depends on many variables (length, tees, etc.). Specific pipe size information should be obtained from a gas supplier.

It is important that equal gas pressure be maintained at all tumbler gas connections. This can best be done by installing a one-inch pipe gas loop as shown in the manual.

WARNING: To reduce the risk of fire or explosion, if the tumbler is to be connected to Liquefied Petroleum (L.P.) gas, a vent to the outdoors must be provided in the room where the tumbler is installed.

A gas loop piping must be installed as illustrated in the manual to equalize gas pressure for all tumblers connected to a single gas service. Other gas-using appliances should be connected upstream from the loop.

IMPORTANT: Line pressure must be maintained at 6-1/2″ ± 1-1/2″ water column inches (1.62 ± .37 kPa) for Natural Gas or 11″ ± .3″ water column inches (2.74 ± .07 kPa) for L.P. Gas with all gas appliances running (tumblers, water heaters, etc.). An in-line pressure regulator may be required on Natural Gas models if the line pressure exceeds eight water column inches (2.00 kPa) with all gas appliances firing.

The following table shows the required gas pipe size for 1,000 BTU Natural Gas (.64 Specific Gravity) at 6.5 ± 1.5 inch water column pressure, based on a 0.3″ water column pressure drop for the given length.

Before connecting, make certain the gas service is the same as specified on the nameplate. Natural Gas service must be supplied at 6.5 ± 1.5 inch water column pressure. L.P. Gas service must be supplied at 11 ± .3 inch water column pressure. If the service is not the same, DO NOT CONNECT the gas line; a conversion will be necessary.

1. Purge air and sediment from the gas service line before connecting it loosely to the tumbler.

2. Purge the remaining air until the odor of gas is detected, then tighten the connection.

3. Use pipe compound resistant to the actions of L.P. gas on all pipe threads.

WARNING: Check all pipe connections, internal and external, for gas leaks using a soapy solution. To reduce the risk of explosion or fire, DO NOT USE AN OPEN FLAME TO CHECK FOR GAS LEAKS! Gas connections should be checked annually for leakage.

The tumbler and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPa). The tumbler must be isolated by closing its individual manual shut-off valve during any pressure testing at a pressure equal to or less than 1/2 psig (3.45 kPa).

IMPORTANT: DO NOT block airflow at the top rear of the tumbler with laundry, etc. Doing so would prevent adequate air supply to the tumbler’s heat chamber.

A typical tumbler enclosure can touch the tumbler’s top and side panels. Be aware that local codes and ordinances must be complied with.

• NOTICE: Clearance of the tumbler cabinet from combustible construction must be a minimum of 12 inches (30.5 cm) at the top.

• 0 inches clearance is permitted for the first 4 inches (10.16 cm) of the cabinet from the front.

• A minimum of 24 inches (61 cm) is required at the rear for clearance, with 36 inches (91.4 cm) recommended for maintenance purposes.

WARNING: To reduce the risk of serious injury, install lockable doors to prevent public access to the rear of the tumblers.

Lighting the System:

1. Turn the machine disconnect switch, located on the rear of the tumbler, to the “on” position.

2. Turn the gas shut-off valve, located on the rear of the tumbler, to the “on” position (gas valve handle should be parallel with the gas line).

3. Start the tumbler, following the operating instructions that accompanied it.

NOTE: The ignition control circuitry will verify the airflow switch is open before starting the cylinder motor. Once the motor starts, the airflow switch will close. The tumbler will purge air for 18 seconds. Ignition will then start with a three-second release of gas and sparking of the ignitor.

Shutting Down the System:

To shut down, turn the machine disconnect switch to the “off” position and turn the gas shut-off valve to the “off” position (handle should be at a right angle to the gas line).

If ignition does not occur during the first three seconds, the ignition control will “lockout,” causing the gas valve to close and a red button on the ignition control to illuminate.

To reset the ignition system, open the access door and press the red button on the ignition control. Close and lock the access door, verify that the gas shut-off valve is in the “on” position, and return to step three of the lighting procedure to restart the tumbler.

Cams that allow other timer increments are available. To figure time increments, use this formula: Timer Motor Speed (60) divided by the number of pins on the cam = Cycle Length (minutes).

Removal of Existing Timing Cam:

1. Rotate the cam by hand until the “V” notch lines up beneath the ratchet tooth.

2. Insert a narrow screwdriver under the nylon cam, close to the clock shaft. Lift gently off the shaft, ensuring the “V” notch clears the ratchet tooth.

Installation of New Timing Cam:

1. Insert the drive into the timing cam with the wide prong in the wide hole of the cam.

2. Position the timing cam and drive fork over the timer shaft, aligning the timer flat with the drive fork and the “V” notch with one of the ratchet teeth.

3. Press the timing cam down firmly to seat it onto the motor shaft.

4. Remove all accumulated time by turning the cam counterclockwise until the switch shuts off. Apply moderate clockwise pressure to the fully seated timing cam and drive against the timing motor shaft. The meter must be advanced electrically for one cycle before an accurate measure of time can be made.

1. Remove or open all panels and inspect accessible bolts, nuts, screws, terminals, and fittings for security.

2. Check belt tension; adjust if necessary.

3. Energize the electrical circuit to the tumbler circuit breaker and turn on the tumbler disconnect switch.

4. Turn on the gas supply at the manual gas shut-off valve (gas models only). The handle should be parallel with the gas supply line when in the “ON” position.

5. Press and hold in the Push-to-Start Button for approximately three (3) seconds. Release the button and open the cylinder door. The cylinder should stop rotating within seven (7) seconds after the door is opened 3″ (7.5 cm) plus or minus 1/4″ (0.635 cm). If not, adjust the cylinder door interlock.

6. Load the tumbler with clothes or clean rags.

7. Start the tumbler and check the burner flame; adjust the gas inlet shutter if necessary.

8. Check air flow switch operation by opening the lint panel. The heating system should shut off when the lint panel is opened approximately 1-1/2″ (3.81 cm). Adjust if necessary.

9. Turn off the tumbler.

10. Check air flow switch operation by opening the lint panel with a full load. Heating systems should shut off when the lint panel is opened approximately 6″ (15.24 cm).

1. Set the temperature selector to HIGH and set the drying and cool down selectors to their maximum settings.

2. Press and hold in the Push-to-Start Button for approximately three (3) seconds. The motor will start, the heat system will turn on, the drying indicator will light, and the drying selector will rotate counterclockwise.

3. When the drying selector reaches zero (0), the heat system will shut off, the drying indicator will turn off, the cooling indicator will light, and the cooling selector will rotate counterclockwise.

4. When the cooling selector reaches zero (0), the motor will stop and the cooling indicator will turn off, indicating the drying cycle is finished.

NOTICE: Both air inlet shutters on the burner must be adjusted for proper combustion and maximum efficiency. Before adjusting, ensure all lint is removed from the lint compartment and screen.

1. Unlock and open the access door.

2. Start the tumbler and check the flame pattern. A correct flame is primarily blue with small yellow tips and bends to the right of the heater section. Too little air is indicated by a yellow, lazy, and smokey flame.

3. To adjust the air shutter, loosen the air inlet shutter adjusting screw.

4. Open or close the air shutter as necessary to obtain the proper flame intensity.

5. After adjustment, tighten the air shutter adjusting screw securely.

6. If the shutter is correctly adjusted but the flame pattern is straight up, it indicates insufficient primary air is flowing through the tumbler. A flame pattern that flares to the right and left indicates no air is flowing through the tumbler.

NOTICE: The control panel must be in place and the access door closed before attempting to adjust the air flow switch. Air flow switch operation may be affected by a clogged lint screen, lack of make-up air, or obstructions in ductwork. These conditions must be checked and corrected before adjusting the switch.

1. Load the tumbler.

2. Start the tumbler. Open the lint panel 6 inches (15.24 cm). The airflow disc should move away from the cabinet, opening switch contacts and shutting off the heat system. This indicates proper adjustment.

3. If the switch does not open as described, it needs to be MORE sensitive. Depress the spring clip and move the counterweight toward the disc. Retest and continue moving the counterweight toward the disc until it operates correctly.

4. If the switch opens BEFORE the lint panel is opened 6 inches, it needs to be LESS sensitive. Depress the spring clip and move the counterweight away from the disc. Retest and continue moving the counterweight away from the disc until it operates correctly.

1. Start the tumbler following operating instructions.

2. Slowly open the loading door. The cylinder and heating system should stop when the door is open 3 inches (7.5 cm) plus or minus 1/4 inch (0.635 cm).

3. Slowly close the loading door. The loading door switch should close with an audible “click” when the door is closed 3 inches (7.5 cm) plus or minus 1/4 inch (0.635 cm).

4. If the switch does not close at the correct point:

a. Close the loading door completely.

b. Loosen the lower screw on the switch coupler and rotate the switch coupler COUNTERCLOCKWISE until it stops.

c. Tighten the lower screw on the switch coupler.

d. Return to step 1 to verify the operation.

The door strike must be adjusted to have sufficient tension to hold the loading door closed against the force of the tumbling load. Proper adjustment is when 8 to 15 pounds (35.6 N – 66.7 N) of pull is required to open the door.

To adjust, open the door, loosen the jamnut on the door strike, and turn the door strike screw in or out as required. Retighten the jamnut when finished.

WARNING: To reduce the risk of serious injury or death, disconnect power to the tumbler before performing this operation.

Proper tension is when the belt can be depressed approximately 1/2 inch (1.27 cm) by applying light thumb pressure at a point midway between the sheave and motor pulley.
