1.Instructions for correct operation
◎ 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.
① This unit is designed exclusively for use with R410A. Do not use
any refrigerant other than R410A.
② To protect the compressor,turn on power for the air conditioner
6 hours before operation so as warm up sufficiently the dome
temperature of compressor.
③ Open the service valves of liquid pipe at first. Secondarily open
the one of gas pipe. Before you operate the unit,make sure again
that the service valves are in open position.
④ Please note that the pressure valves detected at the charge port
in the unit and the gas service valves 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.
