For F and variable-speed models only, clean the AC drive box filter(s) weekly or more frequently as needed: 1. Wash the filter with warm water and allow filter to air dry. As an alternative, the filter may be vacuumed clean. IMPORTANT: The control module cover and fan filter must be in place for the fan to properly cool the AC inverter drive. Failure to observe this warning will void the warranty and could lead to expensive AC inverter drive repair. Monthly NOTE: Disconnect power to the machine at its source before performing the monthly maintenance procedures. 1. Use the following procedures to determine if V-belt(s) require replacement or adjustment. Call a qualified service technician in either case. a. Check V-belt(s) for uneven wear and frayed edges. b. For groove-pulley drive systems, verify alignment by placing a straightedge across both pulley faces. The straightedge should make contact with the pulleys in four places. Refer to Figure 7.

For flat-pulley drive systems, verify allowable distance of belt from edge of pulley. Refer to Table 1 below. Flat-Pulley Alignment Model Allowable Distance from Edge 20 .09 in. (2 mm) 30 .09 in. (2 mm) 40 .09 in. (2 mm) 60 .38 in. (10 mm) 1 2 Table 1 d. For F and variable-speed models only, verify that V-belts are properly tensioned by applying a set force to the belts and measuring the deflection to determine the belt tension. Refer to Table 2 for the acceptable belt’s tension ranges. Belt tension measurements should be taken as close to the center of the belt span as possible. Refer to Figure 8. 1 2 Deflection Span Length H039I Figure 8 Belt Tension Testing for Variable-Speed Models Model Belt Belt Span Deflection Range Force Min – Max 40 Motor-Basket 16.9 in.

For 80 and 125 pound capacity models only, 3. lubricate bearings and seals each month OR after every 200 hours of operation. 4. a. Use a premium-grade lithium-based #2 grease. Never mix two types of grease, such 5. as petroleum and silicone. b. Pump the grease gun slowly, permitting only the following number of strokes: • Bearing grease fitting, 2 strokes • Seal grease fitting, 2 stroke NOTE: Do not pump the grease gun until grease 6. comes out of the bearing housing. This can result in overlubrication, causing damage to bearings and seals. Remove back panel and check overflow hose and drain hose for leaks. Unlock and remove the top cover and check the supply dispenser hoses and hose connections. Clean inlet hose filter screens: a. Turn water off and allow valve to cool, if necessary. b. Unscrew inlet hose and remove filter screen. c. Clean with soapy water and reinstall. Replace if worn or damaged. Tighten motor mounting bolt locknuts and bearing bolt locknuts. Check to see that the pin is in place. F8208401 © Copyright, Alliance Laundry Systems LLC – DO NOT COPY or TRANSMIT Maintenance 7. Use compressed air to clean lint from motor. 8. Clean interior of machine, both basket and shell, by wiping with a water-soaked sponge or cloth. 9. Use compressed air to clean all electrical components of moisture and dust. 10. Verify the insulation is intact on all external wires and that all connections are secure. If bare wire is evident, call a service technician. 11. For F and variable-speed models only, clean AC drive cooling fan blades monthly (more often if required by the condition of the air). Quarterly NOTE: Disconnect power to the machine at its source before performing the quarterly maintenance procedures. 1. Tighten door hinges and fasteners, if necessary. 2. Tighten anchor bolts, if necessary. 3. Verify that the drain motor shield is in place and secure, if so equipped. 4. Check all painted surfaces for exposed metal. (Matching paint is available from the manufacturer.) • If bare metal is showing, paint with primer or solvent-based paint. • If rust appears, remove it with sandpaper or by chemical means and then paint with primer or solvent-based paint. 5. Clean customer-supplied steam filter, where applicable. Refer to Figure 9. a. Turn off steam supply and allow time for the valve to cool. b. Unscrew cap. c. Remove element and clean. d. Replace element and cap. Figure 9 H042I 1 Cap 2 Filter Element 6. Check the bearing mounting bolts to make sure they are torqued properly. Refer to Table 3 for specifications.
