To protect the compressor, turn on the
power to the outdoor unit at least 6
hours prior to test operation.

Confirm that stop valves of both liquid
side and gas side are opened.
<Make sure that outer panel and
piping cover are closed before
operation (danger of electric
shock). >

After air purge by vacuum pump,
refrigerant pressure may not rise
even though the stop valve is

or the like. Operation is no problem.
