manual abstract
gas models there is no regulator on valve 17 NOTE: If correct w.c. pressure cannot be achieved, problems may be due to an undersized gas supply line, a faulty or underrated gas meter, etc. TO CONVERT FROM NATURAL TO L.P. GAS 1. Disconnect electrical power to dryer. 2. Close all shut-off valves in dryer gas supply line. 3. Disconnect gas valve wiring. NOTE: Identify location of each wire for correct re-installation. 4. Break union connection (nut) between union shut off and gas valve. 5. Loosen and remove screws (4) from pipe brackets holding the gas valve/manifold assembly to the gas valve plate. 6. Remove gas valve/manifold assembly form dryer. 7. Unscrew main burner orifice and replace with L.P. orifices supplied. NOTE: Use extreme care when removing and replacing orifices. These orifices are made of brass which are easily damaged. 8. To convert gas valve for use with L.P. gas, refer to instructions included in kit envelope (#f92-0737) supplied. 9. Reverse procedure for installing valve manifold assembly to dryer. IMPORTANT: External regulation of a consistent gas pressure of between 10.5 and 11.0 inches water column must be provided. 10. Open all shut off valves and test for leaks. IMPORTANT: Do not test for leaks with an open flame. Use soapy water solution or product _intended for that purpose. 11. Operate dryer through one complete cycle to insure proper operation. IMPORTANT: Conversion should be performed by competent technicians in accordance with local and state codes. Improper assembly or adjustment can cause hazardous condition. 18 NOTE: There is no regulator provided in an L.P. dryer. The water column pressure must be regulated at the source (L.P. tank), or an external regulator must be added to each dryer. 12. Call American Dryer Corp. for L.P. conversion kits or the proper orifices for natural or L.P. gas. TO REPLACE DSI MODULE 1. Discontinue power to the dryer 2. Remove the wires connected to the terminal strip at the bottom of the module. 3. Remove the soft orange high voltage wire from the module. 4. Remove the four (4) pal nuts securing the module to the modular mounting bracket. 5. Replace module by reversing process. C. THERMOSTATS AND TEMPERATURE SENSOR TO REPLACE HI-LIM1T THERMOSTAT 1225°) This thermostat is an important safety device serving as an added protection against failure of the air sail switch to open in the event of motor failure or reduced air flow condition. IMPORTANT: Under no circumstances should heat circuit safety devices ever be disabled. 1. Discontinue power to dryer. 2. Disconnect wires from hi-limit thermostat. 3. Loosen the two screws securing hi-limit bracket to the dryer. Slide bracket and remove the bracket and hi-limit from dryer. 4. Remove the two pal nuts securing the hi-limit to the bracket, remove hi-limit. 5. Reverse procedure for installing new thermostat. FLAME SENSOR HAS VAIVC cnon TAM. pea t collar - 19 IQ REMOVE THE TEMPERATURE SENSOR OR HIGH HEAT PROTECTOR A. HIGH HEAT PROTECTOR 1. Discontinue power to dryer 2. Open control door on AD-235 remove lint drawer. On AD-230 open lint access panel and remove lint screen. 3. Locate temperature sensor bracket assembly on the side of the basket. Loosen the two phillips head screws. Disconnect the connector. 4. Slide bracket toward the rear of the machine and remove the basket assembly from the dryer. 5. At this point you have access to remove either the high heat protector or the temperature sensor. 6. To remove the high heat protection remove the two (2) screws, washers and nuts holding the high heat protector in place. 7. Remove the high heat protector. 8. Reverse the procedure for installation of new high heat protector. B. TEMPERATURE SENSOR 1. Discontinue power to dryer. 2. Open control door on AD-235 remove lint drawer. On AD-230 open lint access panel and remove lint screen. 3. Disconnect sensor bracket harness connector. 4. Loosen the two (2) phillips head screws securing the bracket assembly to the dryer and remove by sliding bracket towards the rear of the dryer. 5. Disassemble sensor probe from the bracket assembly by removing the top push-on fastener securing the probe to the basket. 6. Disconnect the two (2) orange wires from the high heat temperature thermostat remove the four (4) position connector, wires, and probe from the bracket assembly. 7. Install new probe assembly (ADC P/N: 880251) by reversing procedure. 20 D. SAIL SWITCH ASSEMBLY The sail switch is a heat circuit safety device which controls the heat circuit only. When the dryer is operating and there is proper air flow the sail switch damper pulls in and closes the sail switch, providing all the other heat-related circuits are functioning properly. If an improper air flow occurs, the sail switch damper will release, and the circuit will open. IMPORTANT: Under no circumstances should heat circuit safety devices ever be disabled. TO REPLACE SAIL SWITCH 1. Discontinue p...
