OUTDOOR COIL

If grass clippings, leaves, shrubbery, and debris are kept away from the out- door unit, minimal care should be suf- ficient to keep the system functioning properly. For proper drainage, debris must be removed periodically from the base pan. However, if the outdoor coil becomes dirty, use a vacuum cleaner with soft brush attachment to clean the exterior surface. Vacuum coil surface using an up and down motion. Be care- ful not to bend or damage coil fins. 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.

OUTDOOR COIL—

SEA COAST

If your unit is located near the ocean, special maintenance is required. Ocean mist/breeze carries salt, which is corro- sive to most metals. Although your new unit is made out of galvanized metal and is protected by top-grade paint, you should take the precaution of addi- tional maintenance which consists of periodically washing the unit. By washing all exposed surfaces and coil, you will be adding additional life to your unit. Consult your installing con- tractor for proper intervals/procedures for your geographic area or service contact.

UNIT SUPPORT

Your split-system outdoor 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 that water drains 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.

Heat pumps installed in snowbelt areas should be elevated with support feet or a snow stand.

BEFORE YOU REQUEST A SERVICE CALL

CHECK FOR THESE EASILY SOLVED PROBLEMS:

•Check the indoor and outdoor disconnect switches. Verify that circuit breakers are ON or that fuses have not blown.

•Check for sufficient airflow. Check the air filter(s) for any accumulations of dirt. Check for blocked return-air or supply-air registers. Be sure registers are open and unobstructed.

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

•Check note concerning special fea- tures and time delays in “Operating Your Heat Pump” section.

If your comfort system still fails to operate, contact your servicing dealer for troubleshooting and repairs. Specify your apparent problem, and state the model and serial numbers of your equipment. (You should have them recorded on the last page of this booklet.) With this informa- tion, your dealer may be able to offer helpful suggestions over the phone or save valuable time through knowledgeable preparation for the service call.
