!WARNING
To prevent personal injury or death disconnect all electrical power to the air conditioner be- fore removing access panels or performing any maintenance. Disconnect power to both the indoor and outdoor units. Note: there may be more than 1 elec- trical disconnect switch.
!CAUTION
Although special care has been taken to minimize sharp edges in the construction of your unit, be extremely careful when handling parts or reach- ing into the unit.
CHECK THE AIR FILTER
A dirty air filter will cause excessive strain on the compressor and blower motor. This can cause the components to overheat and automatically shut down. In the extreme, the components will fail and need to be replaced. To avoid inefficient operation or failure of your unit, CHECK THE FILTER(S) EVERY 3 TO 4 WEEKS. Replace filter(s) when neces- sary, or clean the filter(s) if you have the reusable type.
Disposable filters should be replaced by similar, new filters of the same dimensions.
Reusable, permanent filters should
be washed in a solution of cold water and mild detergent, then rinsed and thoroughly dried. THE FILTER MUST BE COMPLETELY DRY BEFORE BEING REINSTALLED. To avoid pro- longed shutdown of your unit while a filter is drying, you should have an extra filter on hand. This would allow you to switch between the two with minimal downtime for your comfort system. Extra filters may be purchased from your dealer.
There are no filters in the outdoor unit of a split system. If your indoor unit is a gas or oil furnace, refer to your furnace Owner's Manual for filter location and procedures for replacement or cleaning.
tensioner, slide the tray into the unit, then secure the thumbscrews.
INDOOR COIL
If the indoor coil has only been operated with a clean filter in place, it should require minimal cleaning.
If coil cleaning is required, call your dealer for service. It may be necessary to clean the coil with a detergent solution and rinse it with water, which could require removing the coil. Do not attempt this yourself.
OUTDOOR COIL
If grass clippings, leaves, shrubbery, and debris are kept away from the outdoor unit, minimal care should keep the sys- tem functioning properly. For proper drainage, debris must be removed period- ically 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 careful 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, spe- cial maintenance is required. Ocean mist/ breeze carries salt, which is corrosive to most metals. Although your new unit is made out of galvanized metal and is pro- tected by
approximately every 3 months, you will be adding life to your unit. Consult your installing contractor for proper intervals/ procedures for your geographic area or service contact.
