Before Operation

• The units that have been left unused for a long period of time shall be electrified for more than 4 hours before startup. Do not start the machine immediately after poweron since this may cause damage to compressor due to inadequate warm-up of lubricating oil.

• Please check if the outdoor unit is covered with ice or snow. If yes, please remove the ice or snow with warm water. However, the water temperature shall not exceed
  122°F since this may cause damage to plastic parts.

• Turn off the main power supply if the machine is expected to be left unused for more than 3 months, because the oil heater band consumes power even if the compressor is not in service. You are recommended to entrust maintenance personnel to check the unit before startup.

• Set the temperature properly. Set the temperature 2°F lower than expected for heating, and set it 2°F higher than expected for refrigeration so as to save resources.

• Do not open doors and windows frequently during the operation of air conditioner.

Automatic Control

This system is designed with the following features.

Note
Please keep the main power supply ON unless the system is left unused for long. By doing so, the automatic drainage device starts to function when the level of accumulated water in machine exceeds the predefined level.

• Three-Minute Stop Protection
  To protect the compressor, it is prevented for at least 3 minutes from functioning after its stop. The compressor automatically gets started in 3 minutes.

• Three-Minute Operation Protection
  Ensure the compressor runs at least for 3 minutes (if the compressor runs for less than 3 minutes, it can’t stop unless 3 minutes elapse even if all indoor temperatures reach the set values). However, the compressor that runs for less than 3 minutes can be brought out of service with the remote control.

• Oil Return Operation
  When an indoor unit is out of service for more than 2 hours during refrigeration, it will run for a few minutes automatically to prevent the detention of refrigeration oil
  in the indoor unit in stopped state.

• Freeze Protection during Refrigeration
  When the outlet air temperature of indoor unit is excessively low, refrigeration may be automatically switched to air supply mode, in which the unit runs for a period of time to avoid frosting on indoor heat exchanger.

• Cold Air Prevention
  To prevent the output of cold air from indoor unit in heating mode, the fan runs at low speed. The fan speed is set based on outlet air temperature of indoor unit.

• Control of Indoor Fan during Defrosting
  The indoor fan is out of service during automatic defrosting of outdoor unit.

• Surplus Heat Output from Indoor Unit
  Upon completion of heating, the indoor fan will keep on running at low speed for approx. 2 minutes to reduce the temperature of machine body.

• Automatic Defrosting
  Press “Run/Stop” key to stop heating. The outdoor unit can automatically detect frost and automatically perform defrosting for up to 10 minutes.

• Overload Protection
  Heating stops when outdoor temperature is excessively high during heating. The heating resumes when the outdoor temperature drops to a certain level.

Note
If the unit stops due to power breakdown, the system will not automatically get into service even if power supply is restored.
Please restart the unit from Step 1. The settings will not get lost in the case of extremely short power-off time (within 2 seconds). The system will come into operation
automatically in approx. 3 minutes.
