ELECTRIC AIR CONDITIONER Owner’s Manual OWNER’S INFORMATION User’s information for the operation and maintenance of your new residential air conditioner. IMPORTANT FACTS To better protect your investment and to eliminate unnecessary service calls, familiarize yourself with the following facts: · Your air conditioning system should never be operated without a clean, properly installed air filter. Plan to inspect the filter periodically.
A clogged air filter will increase operating costs and shorten the life of the unit. · Supply-air and return-air registers should not be blocked. Drapes, furniture, and toys are some of the items commonly found obstructing grilles. Restricted airflow lessens the unit’s efficiency and life span. The outdoor unit must have unrestricted airflow. Do not cover the unit, lean anything against it, or stand upon it. Do not allow grass clippings, leaves, or other debris to accumulate around or on top of the unit. Maintain a 12-in. minimum clearance between the outdoor unit and tall grass, vines, shrubs, etc. · Your multipurpose indoor thermostat is the control center for your air conditioning system.You should familiarize yourself with its proper operation. Attempting to control the system by other means–for instance, switching the electrical supply power ON and OFF–may cause damage to the unit. · Thermostat “jiggling ” causes rapid-cycling, which is potentially damaging to the compressor. Do not move the temperature selector on the thermostat for any reason for at least 5 minutes after the compressor has shut off. · You may find that you can maintain greater personal comfort by running the fan continuously. “Air pockets ” can form due to the structure of the house, placement of registers, etc. These air pockets may be too cool or warm for your liking. Continuous fan operation minimizes any temperature differences. Also, systems equipped with electronic air cleaners and/or humidifiers offer the added benefits of having the air continuously cleaned year-round, and humidified during the winter season. · Your air conditioner will remove humidity from your home during the cooling season. After a few minutes of operation, you should be able to see water trickle from the condensate drain of the cooling coil. Check this occasionally to be sure the drain system is not clogged. Of course, don’t expect to see much drainage if you live in a very dry environment. REGULAR DEALER MAINTENANCE In addition to the routine maintenance that you perform, your home comfort system should be inspected regularly by a properly trained service technician. The inspection (preferably each year, but at least every other year) should include the following: · Routine inspection of air filter(s). Replacement or cleaning as required. · Inspection and cleaning of the blower wheel, housing, and motor. · Inspection and, if required, cleaning of indoor and outdoor coils. · Inspection of the indoor coil drain pan, plus the primary and secondary drain lines. If supplied, the auxiliary drain pan and line should be inspected at this time. Service should include cleaning if required.
