This knowledge will be of use in understanding the basicoperation of your new air conditioner.The type of air conditioner you have purchased is a split system.The split-system type has an indoor and an outdoor unit, each ofwhich contains a coil. These units are interconnected by refrig-erant tubes, as shown in Fig. 1.Each unit has a rating plate affixed to it which provides necessaryinformation for specific identification of a unit. You shouldfamiliarize yourself with the product, model, and serial numberslisted on each rating plate. Record them for future reference onthe last page of this booklet.IMPORTANT FACTSTo better protect your investment and to eliminate unnecessaryservice calls, familiarize yourself with the following facts:• Your air conditioning system should never be operated withouta clean air filter properly installed. Plan to inspect the filter peri-odically. A clogged air filter will increase operating costs andshorten the life of the unit.• Supply-air and return-air registers should not be blocked.Drapes, furniture, and toys are some of the items commonlyfound obstructing registers. Restricted airflow lessens the unit’sefficiency and life span.• The outdoor unit must have unrestricted airflow. Do not coverthe unit, lean anything against it, or stand on it. Do not allow grassclippings, leaves, or other debris to accumulate around or on topof the unit. Maintain a 12-in. minimum clearance between theoutdoor unit and tall grass, vines, shrubs, etc.• Your multipurpose indoor thermostat is the control center foryour air conditioning system. You should familiarize yourselfwith its proper operation. Attempting to control the system byother means—for instance, switching the electrical supply powerON and OFF—may cause damage to the unit.• Thermostat “jiggling” causes rapid-cycling, which is poten-tially damaging to the compressor. Do not move the temperatureselector on the thermostat for any reason for at least 5 minutesafter the compressor has shut off.• You may find that you can maintain greater personal comfortby running the fan continuously. Air pockets can form due to thestructure of the house, placement of registers, etc. Thesepockets may be too cool or warm for your liking. Continuous fanoperation minimizes any temperature differences. Also, systemsequipped with electronic or mechanical air cleaners and/orhumidifiers offer the added benefits of having the air continuouslycleaned year-round and humidified during the winter season.• A system equipped with a heat or energy recovery ventilatoroffers the advantage of exhausting stale air from the home andallowing fresh air in from the outdoors while minimizing heatloss.WARNINGTo prevent personal injury, death, or propertydamage, read and follow all instructions andwarnings, including labels shipped with or at-tached to the unit before operating your new airconditioner.!Fig.1—Typical Split-SystemInstallation
