Clean-as necessary. 4. Inspect electrical connections for tightness and controls for proper Operation each heating and cooling season. Service as neccssary. A WARNING: As with any mechanical equipment, personal injury can result from sharp metal edges. Be careful when removing parts. A. Air Filter To clean or replace air filter, grasp it at bottom and lift it out of unit. Clean filter using cold water. Rinse clean and let dry. Oiling or coating of filter is not required. To replace, stand filter in rack with binding facing coil. Press top edge under access panel. NOTE: Steel rods in filter prevent it from being pulled into coil. Retain these rods and reinstall after cleaning or before replacement if new filter is used. A CAUTION; Never operate unit without a filter. B, Cooling Coil, Drain Pan, and Condensate Drain The cooling coil is easily cleaned when it is dry. Inspect coil and clean (if necessary) before each cooling season. To check or clean cooling coil, remove blower/heater access panel to gain full access to cooling coil. If coil is coated with dirt or lint, vacuum with a soft brush attachment. Be careful not to bend coil fins. If coil is coated with oil or grease, clean it with a mild detergent-and-water solution. Rinse coil with clear water. Be careful not to splash water onto insulation. Inspect drain pan and condensate drain at same time cooling coil is checked. Clean drain pan and condensate drain by removing any foreign matter from pan. Flush pan and drain tube with clear water. If drain tube is restricted, it. can generally be cleared by high-pressure water. Cut plastic line and work outside condensate pan and away from coil to clear drain tube. NOTE: There MUST be a trap in condensate line. Trap must be at least 3-in. deep, not higher than the bottom of unit condensate drain opening, and pitched downward to an open drain or sump. A CAUTION; Do not use caustic household drain cleaners in condensate pan or near coil. Drain cleaners can quickly destroy coils. C. Blower Motor and Wheel Clean blower motor and'wheel when cooling coil is’cleaned. To clean or service wheel or motor, proceed as follows; 1. Pull unit disconnect (when used) and remove blower access panel. 2. Disconnect motor electrical leads from control box and capacitor. Mark location of v^ireS for reassembly. 3. Remove 3 bolts holding motor mount to blower housing while supporting motor shell with hand. 4. Pull motor inlet ring and blower wheel assembly out of blower housing. 5. With blower wheel, inlet ring, and motor mount still attached to motor, place motor on flat, horizontal surface, shaft up. Mark position of wheel on motor shaft for reassembly. 6. Loosen blOWtr wheel setscrew and remove blower wheel from motor shaft. NOTE: Further disassembly of motor and mount is not necessary ' as adequate clearance is available to clean motor. 7. Clean blower motor and wheel using a vacuum with a soft brush attachment. Remove grease with a mild solvent such as hot water and detergent. Be careful not to disturb balance weights (clips) on blower wheel vanes. Do not drop or bend wheel as balance will be affected. To reassemble unit, proceed as follows; 1. Place motor with mount attached on flat, horizontal surface with shaft up. 2. Set inlet ling bn lop of motor mount grommets/ Center inlet ring flush on all 3 grommets. 3. Slide blower wheel onto motor shaft with setscrew upward and aligned with shaft flat portion. Vertically position wheel along shaft to position marked during disassembly. NOTE: If previous shaft was not marked or if replacing previous motor, set blower wheel position by sliding blower wheel along motor shaft to 1-1/8 in. above rubber grommets. (See Fig, 17,) 4. Hold blower wheel in place and carefully tighten setscrew. 5. Position motor and blower wheel assembly to blower housing as originally oriented. 6. Secure motor mount to blower housing using bolts previously removed. 7. Attach green wire to blower housing with screw. 8. Connect electrical and capacitor leads to original terminals. 9. Replace blower access door and tighten all 4 screws, 10. Reinsert disconnect pullout only after blower access door is secured. Test blower for proper operation. -20- /14/2008/THU 03:50 PM UTC TECH PUB FAX No. 317 240 5662 BLOWER WHEEL INLET RING A8GÛ06 Fig. 17—FF1A/FF1B Motor, Infet Ring, and Blower Wheel Assembly FD3A SERVICE AND TROUBLESHOOTING A WARNING; Before installation or servicing system, always turn off main power to system.
