SECTION II Installation Instructions RECEIVING INSPECTION Upon delivery, visually inspect crate carton and parts for any visible shipping damage. If crate, carton or cover are damaged or signs of possible damage are evident, have carrier note condition on shipping papers before shipping receipt is signed, or advise carrier of condition as soon as it is discovered. Advise carrier of any damaged or missing articles as soon as possible.
Proper sized exhaust ducts are essential for proper operation. All elbows should be sweep type. Do not install elbows with a radius less than shown in table below. Exhaust ducts must be assembled so interior surfaces are smooth to reduce accumulation of lint. Do not use sheet metal screws to join vent sections. Improperly sized or assembled ductwork causes excess back pressure which results in slow drying, lint collecting in duct, lint blowing back into room, and increased fire hazard.
維WARNING 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. 維WARNING Solvent gases and vapors from dry cleaning machines create acids when drawn through the heater of a drying tumbler. These acids are corrosive to the drying tumbler as well as to the laundry load being dried.

GAS CONNECTIONS (Gas Drying Tumblers) Before connecting gas piping to tumbler, make certain gas service is same as that specified on nameplate (near gas connection), Page 5. Purge air and sediment from gas service line before connecting it loosely to tumbler. Purge remaining air until odor of gas is detected, then tighten connection. Use pipe compound, resistant to actions of L.P. gas, on all pipe threads. NATURAL GAS service must be supplied at 6¹⁄₂ ± 1¹⁄₂ inch water column pressure (1.62 ± .37 kPa).
DRYING TUMBLER ENCLOSURE CONSTRUCTION 維 WARNING IMPORTANT: DO NOT block airflow at top rear of tumbler with laundry, etc. Doing so would prevent adequate air supply to tumbler’s heat chamber. To reduce the risk of serious injury, install lockable doors to prevent public access to rear of tumblers. A typical tumbler enclosure is shown in Figure 23. Note that enclosure does touch tumbler top and side panels. Note, too, minimum and maximum dimensions.
STEAM REQUIREMENTS (Steam Drying Tumblers) information should be obtained from the steam system supplier or a qualified steam fitter. Size of steam service pipe is dependent upon many variables (length, tees, high pressure system, low pressure system, etc.
STEAM CONNECTIONS (Steam Drying Tumblers) NOTE: See Figure 25 for sizing of steam lines. Piping must also be sized accordingly for length of runs, and number of elbows. 30.
LIGHTING AND SHUTTING DOWN GAS IGNITION SYSTEM during first three seconds ignition control will “lockout” causing gas valve to close and a red button on ignition control to illuminate. 1. Turn machine disconnect switch, located on rear of tumbler, to the “on” position. To reset ignition system , open access door and press red button on ignition control. Close and lock access door, verify that gas shut-off valve is in the “on” position and return to step three. 2.

Rotate cam by hand until "V" notch lines up beneath the ratchet tooth see Figure 28. 2. Insert narrow screwdriver under nylon cam, close to the clock shaft. Lift gently off shaft. Make sure that pressure is directed upward and that the "V" notch clears the ratchet tooth. Figure 27 Cams that allow other timer increments are available through your distributor.
PRELIMINARY OPERATING CHECKS 1. Remove or open all panels and inspect accessible bolts, nuts, screws, terminals and fittings for security. 6. Load tumbler with clothes or clean rags. 7. Start tumbler and check burner flame, adjust gas inlet shutter if necessary (refer to Adjustment Section). 2. Check belt tension, adjust if necessary (refer to Adjustment Section). 8. Check air flow switch operation by opening lint panel. Heating system should shut off when lint panel is opened approximately 1-1/2" (3.
NOTES 52 M412616
SECTION III Adjustments MAIN GAS BURNER AIR SHUTTER (All Gas Models) 5. After air shutter is adjusted for proper flame, tighten air shutter adjusting screw securely. Control panel may have to be removed temporarily to loosen air shutter screws to turn shutter. NOTICE: Both air inlet shutters on burner must be adjusted so sufficient air is metered into system for proper combustion and maximum efficiency. Before adjusting inlet shutters be sure that all lint is removed from lint compartment and lint screen.
Electric Models: If switch remains open, or pops open and closed during cycle, heating system will shut off. Cylinder and fan will continue to operate even though air flow switch is malfunctioning. Counterweight should be adjusted so air flow will force disc away from cabinet when lint panel is opened 6 inches (15.24 cm) with a full load. Adjust air flow switch as follows: 1. Load tumbler. Gas Models: If switch remains open, entire unit will shut down when Push-to-start button is released.
LOADING DOOR SWITCH CYLINDER DOOR STRIKE Loading door switch turns off tumbler any time loading door is opened. To adjust loading door switch, follow these steps: The door strike must be adjusted to have sufficient tension to hold loading door closed against force of load tumbling against it. Proper adjustment is when 8 to 15 pounds (35.6 N - 66.7 N) pull is required to open door. 1. Start tumbler following operating instructions which accompanied it.
DRIVE V-BELT 維 WARNING To reduce the risk of serious injury or death, disconnect power to the tumbler before performing this operation. Proper tension is when 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. 1. Remove guard from rear of tumbler. 2. To adjust belt tension, loosen adjusting bolt holding idler housing assembly to housing support. 3. To a. b. c. tighten V-belt: Loosen lower nut on adjusting bolt.
SECTION IV Preventive Maintenance Instructions DAILY 6. Ensure lint screen covers entire opening in lint screen hood. Gaps between lint screen and lint screen hood allows lint to flow into ductwork system restricting air circulation. 1. Make certain drying cycle has ended. 2. Open loading door. 3. Unlock and remove lint panel. 7. Wipe any accumulated lint off thermostat sensing probe. Lint buildup on sensing probe will cause overheating of tumbler. 4. Remove accumulated lint in lint compartment.
Quarterly 1. Deactivate electrical circuit by turning off disconnect switch on rear of tumbler. 6. Remove screws holding rear drive guard to back of tumbler. 2. Perform daily cleaning of accumulated lint. 7. Inspect belts for wear and proper tension (refer to Adjustments section). 3. Perform monthly inspection and cleaning of accumulated lint. 8.
