Before you turn on power, please carefully read the installation manual and the operation manual supplied with the unit.

Please check the following points before operation.

This unit is designed exclusively for use with R410A. Do not use any refrigerant other than R410A.

To protect the compressor, turn on power for the air conditioner 6 hours before operation so as to warm up sufficiently the dome temperature of compressor.

Open the service valve of liquid pipe at first. Secondarily open the one of gas pipe. Before you operate the unit, make sure again that the service valve are in open position.

Please note that the pressure values detected at the charge port in the unit and the gas service valve are different during the cooling operation and the heating operation. High pressure is replaced with the low pressure depending on whether it is in the cooling or heating operation.

You should test run the unit before starting normal operation to see if the addresses are set correctly and if the indoor electronic expansion valve operates properly. For more information, please refer to the technical manual.
