How a Tumbler Works 1 2 Introduction A tumbler uses heated air to dry loads of laundry. 1 When the motor is started, the exhaust fan pulls room temperature air in through the air intake at the rear of the tumbler and over the heat source (burner flame for gas, heating element for electric, and coil for steam). 3 2 3 The heated air moves into the cylinder, where it is circulated through the wet load by the tumbling action of the cylinder. The air then passes through the lint filter, exhaust fan, and is vented to the outdoors. TMB2347S 70399901 Copyright, Alliance Laundry Systems LLC DO T COPY or TRANSMIT 9

Section 4 Adjustments WARNING To reduce the risk of electric shock, fire, explosion, serious injury or death: Disconnect electric power to the tumbler before servicing. Close gas shut-off valve to gas tumbler before servicing. Close steam valve to steam tumbler before servicing. Never start the tumbler with any guards/panels removed. Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the tumbler is properly grounded. W002 19. Main Gas Burner Air Inlet Shutters (All Gas Models) Refer to Figure 1. CAUTION The air inlet shutters on the burner must be adjusted so sufficient primary air is metered into the system for proper combustion and maximum efficiency. Before adjusting the inlet shutter be sure that all lint is removed from lint compartment and lint screen. W281 Air inlet shutter adjustments will vary from location to location and will depend on the vent system, number of units installed, make-up air and line gas pressure. Opening the shutter increases the amount of primary air supplied to the burner while closing the shutter decreases the air supply. Adjust the air shutter as follows: a. Remove access panel. b. Start tumbler and check the flame pattern. Correct air and gas mixture is indicated if the flame pattern is primarily blue, with small yellow tips, and bends to the left of the heater section. Too little air is indicated if the flame is yellow, lazy and smokey. c. To adjust the air inlet shutter, loosen locking screw. d. Slide shutter in or out as necessary to obtain desired flame intensity. e. After shutter is adjusted, tighten locking screw securely. f. If the flame pattern is straight up, insufficient air is flowing through the tumbler. A flame pattern that flares to the right and left indicates that no air is flowing through the tumbler.

Airflow Switch The airflow switch is set at the factory for proper operation. adjustment necessary. IMPORTANT: Airflow switch vane must remain closed during operation. If it opens and closes during the drying cycle, this indicates insufficient airflow through the tumbler. If switch remains open, or pops open and closed during the cycle, the heating system will shut off. The cylinder and fan will continue to operate even though the airflow switch is indicating insufficient airflow. 21. Loading Door Strike Refer to Figure 2. The door strike must be adjusted so it has sufficient tension to hold loading door closed against the force of a tumbling load. The door strike is properly adjusted when 8-15 lbs. (17.6-33 kg) of pull is required to open door. To adjust, open door, loosen nut and turn door strike screw in for less tension or out for more tension. Tighten nut. Refer to Figure 2. 22. Cylinder Belt Tension 120 Pound Models: TE: Belt tension from step pulley to cylinder shaft pulley can be measured to ensure proper installation in one of the following ways: Burroughs Belt Tension Gauge initial reading 70-80 pounds. Force to deflect belt.38 inch at midspan with initial tensioning 6.5 pounds. Burroughs Belt Tension Gauge reading after run 55-65 pounds. 170 Pound Models: TE: Belt tension from cylinder drive motor pulley to step pulley can be measured to ensure proper installation in one of the following ways: Burroughs Belt Tension Gauge initial reading 60-70 pounds. Force to deflect belt.38 inch at midspan with initial tensioning 6.0 pounds Burroughs Belt Tension Gauge reading after run 45-55 pounds.

Adjustments WARNING To reduce the risk of electric shock, fire, explosion, serious injury or death: Disconnect electric power to the tumbler before servicing. Close gas shut-off valve to gas tumbler before servicing. Close steam valve to steam tumbler before servicing. Never start the tumbler with any guards/panels removed. Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the tumbler is properly grounded. W002 IMPORTANT: Adjusting the cylinder belt tension WILL AFFECT the drive belt tension. You MUST check and readjust the drive belt tension after adjusting the cylinder belt tension. Figure 4 Jackshaft Assembly Attaching Screws Jackshaft Assembly T317PE1B_ 23. Cylinder Clearance The clearance between the cylinder rim and front panel must be adjusted so the cylinder is centered within the front panel opening when the cylinder is fully loaded and is turning. However, the adjustment should be made when the cylinder is empty. TE: If the cylinder is not properly adjusted, the cylinder rim will rub against the front panel. a. Open loading door. b. Check the gap between the center of the front panel top flange and the cylinder rim. Proper adjustment is when the gap is 8/32 inch ± 3/32 inch. Refer to Figure 5. Perform steps d through i to adjust the cylinder rim/front panel flange clearance. c. Check the cylinder fore/aft clearance between the inside front of the cylinder and the edge of the front panel flange. Proper adjustment is when the gap is 9/32 inch ± 1/32 inch. Refer to Figure 5. Perform steps j through n to adjust the cylinder fore/aft clearance. Cylinder Rim/Front Panel Flange Clearance Adjustment a. Support corner drive guard and remove screws holding corner guard to rear of tumbler. b. Support drive guard cover and remove screws holding guard to rear of tumbler. c. Loosen rear bearing mounting screws. Refer to Figure 6. d. Loosen the locknuts on rear adjustment screws. Refer to Figure 6. e. Turn the adjusting screws in or out as necessary to obtain proper clearance between cylinder rim and front panel. TE: Turning the adjusting screws clockwise will raise the cylinder and turning them counterclockwise will lower the cylinder. Turn both screws evenly to adjust top and bottom clearance. Turn one or the other adjusting screw in or out to adjust side clearance. f. After the cylinder is properly adjusted, tighten the adjusting screw locknuts and the rear bearing mounting screws. g. Install drive guard cover. TE: If adjusting the trunnion housing fails to correct the clearance, the problem is probably due to a worn trunnion shaft or defective bearings. 70399901 Copyright, Alliance Laundry Systems LLC DO T COPY or TRANSMIT 35
