(14). During installation, attach the refrigerant piping securely before running the compressor. If the
compressor is not attached and the stop valve is open during pump-down, air will be sucked in
when the compressor is run, causing abnormal pressure in the freezer cycle which will lead to
breakage and even injury.

Incomplete earth may cause electrical shock, or fire. A high surge current from lightning or other
sources may cause damage to the air conditioner.

electric shocks, or fire.
