Perform the test operation according to following procedure.
-1
Make sure to turn on the power supply
more than 6 hours before operation
start with front panel closed to protect
compressor.

<Make sure that outer panel and
piping cover are closed before

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

like. Operation is no problem.
