SAFETY CONSIDERATION

Recognize safety information. This is the safety-alert symbol ! . When you see this symbol on the unit or in instructions and man- uals, be alert to the potential for personal injury.

Understand the signal word DANGER, WARNING, or CAU- TION. These words are used with the safety-alert symbol. DAN- GER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards that could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor person- al injury or product and property damage.

!WARNING

Improper installation, adjustment, alteration, ser- vice, maintenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified installer, service agency, or your distributor or branch for information or as- sistance. The qualified installer or agency must use factory-authorized kits or accessories when modifying this product.

!WARNING

To prevent personal injury, death, or property damage, read and follow all instructions and warnings, including labels shipped with or at- tached to the unit before operating your new air conditioner.

YOUR COMFORT SYSTEM

Identifying Your System

Take the time to familiarize yourself with the type of system you have. This knowledge will be of use in understanding the basic operation of your new air conditioner.

The split-system type has an indoor and an outdoor unit, each of which contains a coil. These units are interconnected by refrig- erant tubes. (See Fig. 1.)

Each unit has a rating plate affixed to it which provides necessary information for specific identification of a unit. You should familiarize yourself with the product, model, and serial numbers listed on each rating plate. Record them for future ref- erence on the last page of this booklet.

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 air filter properly installed. Plan to inspect the filter peri- odically. 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 effi- ciency and life span.

•The outdoor unit must have unrestricted airflow. Do not cover the unit, lean anything against it, or stand on 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 potential- ly 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 pock- ets may be too cool or warm for your liking. Continuous fan oper- ation minimizes any temperature differences. Also, systems equipped with electronic or mechanical air cleaners and/or humidifiers offer the added benefits of having the air continuously cleaned year-round, and humidified during the winter season.

•A system equipped with a heat or energy recovery ventilator offers the advantage of exhausting stale air from the home and allowing fresh air in from the outdoors while minimizing heat loss.
