Follow the operating instructions on the label attached to the furnace. Failure to follow this warning could result in personal injury. The minimum maintenance that should be performed on this equipment is as follows: 1. Check and clean or replace air filter each month or as required. 2. Check blower motor and wheel for cleanliness and lubrication each heating and cooling season. Clean and lubricate as necessary. (See Step 2.) 3. Check electrical connections for tightness, and controls for proper operation each heating season. Service as necessary. 4. Check for proper condensate drainage; clean as necessary. 5. Check for blockages of combustion-air and vent pipes. A CAUTION As with any mechanical equipment, personal injury could result from sharp metal edges, etc. Be careful when removing parts. Step 1—Air Filter Cleaning and Replacement The air filter arrangement may vary depending on the application. A CAUTION Never operate unit without a filter or with filter access door removed. Failure to follow this warning could result in a fire or personal injury. DOWNFLOW FURNACES ONLY - Each furnace accommodates 2 filters which are installed in the return-air duct. (See Fig. 3.) To clean or replace the filters, proceed as follows: 1. Turn OFF electrical supply to unit. 2. Remove blower access door. 3. Reaching up behind top plate, tilt filters toward center of return-air plenum, remove filters, and replace or clean as needed. 4. Furnaces are equipped with permanent, washable filters. Clean these filters by spraying cold tap water through filter in opposite direction of airflow. 5. Rinse filters and let dry. Oiling or coating of filters is not recommended. 6. Reinstall filters with cross-mesh binding facing blower. 7. Replace access door. 8. Turn ON electrical supply to furnace. UPFLOW FURNACES ONLY — To clean or replace the air filter, proceed as follows: 1. Turn OFF electrical supply to unit. A92117 Fig. 3—Position of Filters in Downflow Furnace CONTROL BOX Fig. 4—Filter Installed for Bottom Inlet AUX J-BOX & BLOWER DOOR SWITCH Fig. 5—Filter Installed for Side Inlet 2. Remove access doors. 3. Release filter retainer spring from behind flange of furnace casing. (See Fig. 4 and 5.) 4. Slide filter out. WA 2 5. Furnaces are equipped with permanent, washable filters. Clean filter by spraying cold tap water through filter in opposite direction of airflow. 6. Rinse filter and let dry. Oiling or coating of filter is not recommended. 7. Place filter in furnace with cross-mesh binding either up or facing blower. 8. Replace access doors. 9. Turn ON electrical supply to furnace. Step 2—Blower Motor and Wheel Maintenance For long life, economy, and high efficiency, clean accumulated dirt and grease from blower wheel and motor annually. The following items should be performed by a qualified service technician: Some motors have prelubricated, sealed bearings and require no lubrication. These motors can be identified by the absence of oil ports on each end of the motor. For motors with oil ports, lubricate as follows: Lubricate motor every 5 years if motor is used for intermittent operation (thermostat FAN switch in AUTO position), or every 2 years if motor is in continuous operation (thermostat FAN switch in ON position). Clean and lubricate as follows: 1. Turn OFF electrical supply to unit. 2. Remove access doors. 3. Upflow furnaces only —remove drain trap and control box: a. Remove control box from bottom side of blower shelf and position to 1 side. b. Disconnect 9-circuit connector PL-13 from blower housing. c. Using backup wrench, disconnect drain pipe at coupling in blower compartment. d. Loosen hose clamp and remove 7/8-in. diameter drain hose from drain trap. e. Loosen hose clamp and disconnect 5/8-in. diameter drain hose at bottom of inducer housing located under blower shelf. f. Remove screw securing drain trap assembly. 4. Downflow furnaces only — disconnect vent pipe, elbow, and auxiliary limit switch. (See Fig. 6.) a. Remove control box from top plate and position to 1 side. AUXILIARY UMIT .SWITCH A92118 Fig. 6—Downflow Furnace Blower Compartment b. Disconnect 9-circuit connector PL-13 from blower housing. c. Disconnect wires from auxiliary limit on blower housing. d. Remove vent pipe enclosure from top side of blower shelf and position to 1 side. e. Loosen hose clamps on outlet elbow and remove elbow. f. Loosen hose clamp on extension pipe outside of furnace and remove pipe. 5. Remove screws securing blower assembly to blower shelf and slide blower assembly out of furnace. 6. Squeeze side tabs of connector PL-13 and pull from blower housing bracket. 7. Mark blower wheel location on shaft before disassembly to insure proper reassembly. 8. Loosen setscrew holding blower wheel on motor shaft. NOTE: Mark blower mounting arms and blower housing so each arm is positioned at the same hole location during reassembly. This will insure that oilers po...
