NOTE
7-1 Make sure to turn on the power at
least 6 hours before starting test
operation to protect the compressor.
Make sure that the outer panel
and piping cover are closed
before operation (danger of
electric shock).
7-2 Conrm that both the liquid and gas
stop valves are opened.
After the air purge of the vacuum pump, the refrigerant pressure may not rise even
though the stop valve is opened. The reason is that the refrigerant system of the outdoor
unit is blocked by the electrical expansion valve or the like. Operation is no problem.
