WARNING
Electrical Information
The complete electical rating of your new room air conditioner is stated on the serial plate. Refer to the rating when checking the electrical requirements.
Be sure the air conditioner is properly grounded. To minimize shock and fire hazards, proper grounding is important. The power cord is equipped with a three-prong grounding plug for protection against shock hazards. Your air conditioner must be used in a properly grounded wall receptacle. If the wall receptacle you intend to use is not adequately grounded or protected by a time delay fuse or circuit breaker, have a qualified electrician install the proper receptacle. Ensure the receptacle is accessible after the unit installation. Do not run air conditioner without side protective cover in place.This could result in mechanical damage within the air conditioner. Avoid fire hazard or electric shock. Do not use an extension cord or an adapter plug. Do not remove any prongs from the power cord.
Electronic Work
WARNING: BEFORE PERFORMING ANY ELECTRICAL OR WIRING WORK, TURN OFF THE MAIN POWER TO THE SYSTEM.

NOTE:
Use terminal 4-way for heat pump connection only. Suggest set the compressor protection time morn than 3 minutes in . If set less than 3 minutes, the compressor will restart delay 3 minutes still. Wall thermostat must be heating changeover 4-way valve. For thermostats that have only one fan speed output (on or auto),the fan speed is determined by how the terminal connector is wired. If Low fan is desired, wire the G output from the thermostat to (LOW- FAN) on the units terminal block. If High fan is desired, wire the G output from the themostat to (HI-FAN) on the units terminal block. The range of set tempreture of Wall thermostat must be in consonance with the range of DIP switch setting. Wall thermostat must be set the type properly in consonance with the unit type : heat pump or no heat pump.
If the has only one electrical heater output, connect the two terminals of HEAT 1 and HEAT 2, the unit can operate two electrical heaters (only for the unit has two electrical heaters). Otherwise operate one electrical heater. Please do not remove the control panel.

FRONT DESK CONTROL
The controller can handle a switch signal from FC(L) and FC(N) input, called front desk control. Input must be 24VAC. If system doesn’t receive a 24VAC signal, it will turn unit off; otherwise, the unit runs in normal control. The DIP switch can control the FRONT DESK CONTROL feature. The DIP switch is on the DOWN position, the unit will be turn off; otherwise,the unit runs in normal control. See FigB.

Description
· HEAT:For heat pump models,the unit can alternate to run between in reverse cycle heat mode and electric heater mode according to the difference between the setting temperature andthe room temperature. · The fan motor cycles with the compressor stop. DRY : In this mode, the air conditioner will generally operate in the form of a dehumidifier. Since the conditioned space is a closed or sealed area, some degree of cooling will continue. NOTE: The reverse cycle and electric heater cannot be run at the same time. In following cases, it is normal that the reverse cycle does not operate. 1.When the outdoor temperatrue is lower than 4°C/40°F or the room temperature falls to 4.5°C/8°F below the set point temperature. 2.There is a 3-minute minimum compressor run time at any setting to prevent short cycling. The indoor fan motors starts before the compressor and stops after the compressor cycles off. 3.Push the S1 on the DIP SWITCHES to UP (ON) position. 4.When frost builds up to the evaporator coils,the unit will defrost automatically and the compressor will cycle off. NOTE: When you select AUTO mode, the FAN speed will be automatically adjusted at the setting temperature and room temperature. · FAN: Fan operation only without heating and cooling. NOTEIf the unit has DIP SWITCHES feature,the temperature range can be setted is controlled by DIP SWITCHES.See DIP SWITCHES CONFIGURATIONS on page 8 for details.
· Push the UP (or DOWN) button to increase (or decrease) the set temperature of the unit in cooling or heating mode.The temperature can be set by increments of 1°C (1°F).The setting temperature appears in the display.
