This Haier product has been engineered and manufactured to a world-class quality standard and it has passed vigorous factory inspections and tests to ensure years of satisfactory service. Please acquaint yourself with your new system by reading this booklet thoroughly. Learn about the system operation and the maintenance required to keep it operating at peak performance. HOW YOUR SYSTEM WORKS Your Heat Pump is designed to work with a matched indoor unit (Refer to Figure 1). The heat pump system heats, filters, dehumidifies and circulates the air inside your home. It uses a compressor, an indoor coil and an outdoor coil to Fig.1 : Heat pump System move heat from inside your house to outside. In summer fans move air across the coils and circulate air in the conditioned space. A thermostat turns the fans and compressor on and off as cooling is needed. Hotter weather means more cooling is required, so your unit will run longer. When the temperature is highest, the unit may run continuously for several hours. During the winter, the heat pump extracts the heat present in cold winter air and pumps the heat into your home, (Yes, there's heat in the air even in the Coldest weather.) 1 03P-0043/AC Manual_fnl 5/28/03 12:23 PM Page 3, English HOW TO OPERATE ! WARNING - To prevent injury, death, or property damage, A read and follow all instructions and warnings, including labels shipped with or attached to unit before operating your new heat pump system. The control center for your heat pump system is your thermostat.* Many different types are used, but they are similar to operate. A typical mechanical thermostat is illustrated in Figure 2. * Accessory, purchased separately. Carefully read the accompanying thermostat manual for complete operating instructions Z! CAUTION - Do not switch your thermostat rapidly “ON” and “OFF”. This could damage your equipment. Always allow at least 5 minutes between changes. ! CAUTION - The thermostat control switch should be used to turn the Z system off. In cold weather if the main power is disconnected for more than 3 hours, turn off the thermostat before restoring the main power to the outdoor unit. After power has been restored to the outdoor unit allow sufficient time (approximately 3 hours) for the crank case heater to warm the compressor before starting the system. Failure to follow this procedure could result in damage to your system. 2 03P-0043/AC Manual_fnl 5/28/03 12:23 PM Page 4, English Cooling Operation Set the thermostat system switch to “COOL” and the fan switch to AUTO”. Then set the temperature by using the temperature selector on the thermostat. Now the system will cool your house whenever the indoor temperature climbs above the thermostat setting. It will shut off when the desired room temperature Is reached. Heating Operation Set the thermostat system switch to “HEAT”, and the fan switch to AUTO". Then set the temperature by using the temperature selector on the thermostat. Now the system will heat your house whenever the indoor temperature climbs below the thermostat setting. It will shut off when the desired room temperature is reached. Fan Only Mode Set the system switch to “OFF” and the fan switch to “ON”. Now the system will run only the fan to circulate and filter the air in your house. Be sure to return the switches to their original positions for normal operation. Continuous Air Circulation Set the system switch to “COOI!! and the fan switch to “ON”, with the temperature selector at the desired level. This provides continuous air filtering and more even temperature distribution. System Off Set the system switch to “OFF” and the fan switch to “AUTO”. This puts the system on stand by mode with no cooling or fan. Let the thermostat do its job. Your system will perform most efficiently when you let the thermostat control it. Select a comfortable thermostat temperature setting, typically between 75° and 80° F. However, you can select the temperature that meets your comfort level. Once the temperature is set, you should leave your thermostat alone. Manually moving the thermostat up or down to extreme settings will not speed up temperature changes. Please remember that your system will not operate properly when the outdoor temperature is low (say below 65° F). A low-ambient kit is required in low ambient conditions. Check with your dealer If needed. SYSTEM MAINTENANCE A heat pump is not a household appliance. It’s a self-contained system that requires professional maintenance and repair. Other than performing the simple maintenance recommended in this booklet, you should not attempt to make any adjustments to your central ...
