Bryant 664A manual Unit Support, Before YOU Request a Service Call, Regular Dealer Maintenance

Reusable, permanent ®lters should be washed in a solution of cold water and mild detergent, then rinsed and thoroughly dried. THE FILTER MUST BE COMPLETELY DRY BE- FORE BEING REINSTALLED. To avoid prolonged shut- down of your unit while a ®lter is drying, you should have an extra ®lter on hand. This would allow you to rotate between the two with minimal downtime for your comfort system. Ex- tra ®lters may be purchased from your dealer.

·The ®lter(s) and ®lter rack for a packaged system are sup- plied and installed by the contractor or dealer. Typically, the ®lter(s) and rack are located in the return-air duct in the unit or behind the return-air grille(s). Have your dealer show you the location of your ®lter(s) and the procedures for removal and replacement.

If you have any questions about the removal and/or cleaning of your ®lter(s), contact your dealer for assistance.

If grass clippings, leaves, shrubbery, and debris are kept away from the unit, minimal care should be sufficient to keep the system functioning properly. However, if the outdoor coil be- comes dirty, use a brush or vacuum cleaner and soft brush attachment to clean the exterior surface. If dirt is deep in the coil, contact your dealer for service. The outdoor-fan motor may have to be disconnected and the top panel removed to gain access to the coil for thorough cleaning. Do not attempt this yourself.

UNIT SUPPORT

Your packaged unit should be maintained at a level position. If its support should shift or settle so that the unit is no longer level, you should correct the condition. Relevel it promptly to assure condensate drainage out of the unit. If you notice that water or ice collects beneath the unit, arrange for it to be drained away from the unit.

BEFORE YOU REQUEST A SERVICE CALL

BEFORE YOU CALL FOR SERVICE, CHECK FOR THESE EASILY SOLVED PROBLEMS:

·Check the disconnect switches. Verify that circuit break- ers are ON or that fuses have not blown.

·Check for sufficient air¯ow. Check the air ®lter(s) for any accumulations of dirt. Check for blocked return-air or supply- air grilles. Be sure grilles are open and unobstructed.

·Check the settings on your indoor thermostat. If you de- sire cooling, see that the temperature control selector is set below room temperature and the SYSTEM switch is on the COOL or AUTO position. If you require warmth, be sure the temperature control selector is set above room temperature and the SYSTEM switch is at HEAT or AUTO. The FAN switch should be set at ON for continuous blower operation or AUTO if you wish the blower to function only while the unit is operating.

If your comfort system still fails to operate, contact your ser- vicing dealer for troubleshooting and repairs. Specify your ap- parent problem, and state the model and serial numbers of your equipment. (You should have them recorded at right.) With this information, your dealer may be able to offer help- ful suggestions over the phone, or save valuable time through knowledgeable preparation for the service call.

REGULAR DEALER MAINTENANCE

In addition to the routine maintenance that you perform, your home comfort system should be inspected regularly by a prop- erly trained service technician. The inspection (preferably each year, but at least every other year) should include the following:

·Routine inspection of air ®lter(s). Replacement or cleaning as required.

·Inspection and cleaning of the blower wheel, housing, and motor. Service should include proper lubrication of these components.

·Inspection and, if required, cleaning of indoor and outdoor coils.

·Inspection of the indoor coil drain pan, plus the drain line. Service should include cleaning if required.

·A check of all electrical wiring and connections.

·A check for secure physical connections of individual com- ponents within units.

·Operational check of the heat pump system to determine actual working condition. Necessary repair and/or adjust- ment should be performed at this time.

Your servicing dealer may offer an economical service con- tract that covers seasonal inspections. Ask for further details.
