Consult a qualified installer, service agency, or your distributor or dealer for information or assistance. The qualified installer or agency must use factory-authorized kits or accessories when modifying this product. YOUR COMFORT SYSTEM A. Identifying Your System Take the time to familiarize yourself with your packaged air conditioning system. This knowledge will be of use in understanding the basic operation of your new air conditioner. The 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 reference in the space provided at the end of this booklet. IMPORTANT FACTS To better protect your investment and to eliminate unnecessary calls, familiarize yourself with the following facts: 1. Your air conditioning system should never be operated without a clean air filter properly installed. Plan to inspect the filter periodically. A clogged air filter will increase operating costs and shorten the life of the unit. —1— 2. Supply-air and return-air registers should not be blocked. Drapes, furniture, and toys are some of the items commonly found obstructing registers. Restricted airflow lessens the unit’s efficiency and life span. 3. 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 on top of the unit. Maintain a 30-in. minimum clearance between the outdoor unit and tall grass, vines, shrubs, etc. 4. Your multipurpose indoor thermostat is the control center for your heat pump 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 (See Fig. 3). 5. 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. air pockets may be too cool or warm for your liking. Continuous fan operation 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. 6. 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. 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. WARNING: FIRE AND ELECTRICAL HAZARD Failure to follow this warning could result in personal injury, death and/or property damage. To prevent serious injury, death, or property damage, read and follow all instructions and warnings, including labels shipped with or attached to unit before operating your new heat pump. 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 select. Most thermostats for air conditioning systems have 3 controls: a temperature control selector, a FAN control, and a SYSTEM or MODE control. A. Cooling Mode When operating in cooling mode, your air conditioner will run in cooling mode until the indoor temperature is lowered to the level you have selected. On extremely hot days, your air conditioner 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: 1. Entrance doors are frequently opened and closed 2. Laundry appliances are being operated 3. A shower is running 4. More than the usual number of people are present in the home 5. More than the normal number of electric lights are in use 6. Drapes are open on the sunny side of the home Fig. 2—Bryant Non-Programmable Thermostat B. Heating Cycle If you own a packaged air conditioner that includes electric heat as an accessory, you need to set your thermostat for heating when it is desired. With the SYSTEM switch of your indoor thermostat set to the HEAT position, the heating section of your home comfort system will operate until room temperature is raised to the level you have selected. Of course, the heating unit will have to operate for longer periods to maintain a comfortable environment on colder days and nights than on moderate ones.
