• Make the electrical connection and leave the system into “stand
by mode”. Do not turn on the system! This is necessary for better
vacuum operation (full OPEN position of Electronic Expansion
Valve - EEV-).

• When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first
before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works
with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle
abnormally high. It may cause explosion and injury.
