IMPORTANT FACTS
To better protect your investment and to eliminate unnec- essary service calls, familiarize yourself with the following facts:
Improper installation, adjustment, alteration, service, main- tenance or use can cause explosion, ®re, electrical shock or other conditions which may cause personal injury or property damage. Refer to this manual. For assistance or additional information consult a quali®ed installer, service agency, distributor, or branch. The quali®ed in- staller or agency must use only factory authorized kits or accessories when modifying this product.
·Your air conditioning system should never be operated with- out a clean air ®lter properly installed. Plan to inspect the ®lter periodically. A clogged air ®lter 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 air¯ow lessens the unit's efficiency and life span.
·Outdoor units must have unrestricted air¯ow. 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, et cetera.
·Your multipurpose indoor thermostat is the control center for your air conditioning system. You should familiarize your- self with its proper operation. Attempting to control the sys- tem by other means Ð for instance, switching the electrical supply power ON and OFF Ð may cause damage to the unit.
·Thermostat ``jiggling'' causes rapid-cycling, which is po- tentially damaging to the compressor. Do not move the tem- perature selector on the thermostat for any reason for at least 5 minutes after the compressor has shut off.
·You may ®nd that you can maintain greater personal com- fort by running the fan continuously. ``Air pockets'' can form due to the structure of the building, placement of registers, et cetera. These air pockets may be too cool or warm for your liking. Continuous fan operation minimizes any
temperature differences. Also, systems equipped with elec- tronic air cleaners and/or humidi®ers offer the added ben- e®ts of having the air continuously cleaned year-round, and humidi®ed 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.
OPERATING YOUR AIR CONDITIONER
The operation of your air conditioning system is controlled by the indoor thermostat. You simply adjust the thermostat and it maintains the indoor temperature at the level you se- lect. Most thermostats for air conditioning systems have three controls. These are the temperature control selector, FAN switch, and SYSTEM switch.
The temperature control selector is a dial or button(s) that allow
you to establish the degree of temperature that you wish to maintain for your personal comfort. Some thermostats pos- sess two temperature control selectors: one for setting the temperature desired during the cooling cycle, and one to set the heating operation temperature (if the accessory electric heater is used). Typical settings are 78 degrees Fahrenheit for cooling and 68 degrees for heating.
The FAN switch offers two options for controlling the blower: AUTO and ON. When set to AUTO, the blower will run dur- ing the time the air conditioner is operating. When the FAN switch is set at the ON position, the blower will run con- tinuously.
Typically, the SYSTEM switch on your thermostat offers the following selections: COOL, OFF, and HEAT. Your thermo- stat may also have a fourth selection, AUTO. The air con- ditioner will not operate when the SYSTEM switch is set at the OFF position. With the SYSTEM switch set at COOL, the cooling section of your comfort system will operate when the indoor temperature rises above the level that you wish to maintain. With the SYSTEM switch set at the HEAT posi- tion, the accessory electric heater will operate automatically whenever the indoor temperature falls below the level that you have selected.
The AUTO selection found on some thermostats provides for automatic changeover between cooling and heating cycles. With the SYSTEM switch set in the AUTO position, the cool- ing mode is activated when the indoor temperature rises above the thermostat cooling temperature setting, or the heating mode will be activated when the indoor temperature drops below the thermostat setting for the heating cycle.
COOLING CYCLE
When operating in the cooling cycle, your air conditioner will run until the indoor temperature is lowered to the level you have selected. On extremely hot days, your air condi- tioner will run for longer periods at a time and have shorter ``off'' periods than on moderate days.
The following are typical conditions that add extra heat and/or humidity to your home. Your air conditioner will work longer to keep your home comfortable under these conditions:
·Entrance doors are frequently opened and closed
·Laundry appliances are being operated
·A shower is running
