Safety Precautions
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.
Be sure to establish an earth. Do not earth the unit to a utility
pipe, arrester, or telephone earth. Incomplete earth may cause
electrical shock, or fire. A high surge current from lightning or
other sources may cause damage to the air conditioner.
Be sure to install an earth leakage breaker. Failure to install an
earth leakage breaker may result in electric shocks, or fire.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in
order to avoid a hazard.
CAUTION!
Do not install the air conditioner in a place where there is
danger of exposure to inflammable gas leakage. If the gas leaks
and builds up around the unit, it may catch fire.
Establish drain piping according to the instructions of this
manual. Inadequate piping may cause flooding.
Tighten the flare nut according to the specified method such
as with a torque wrench. If the flare nut is tightened too hard,
the flare nut may crack after a long time and cause refrigerant
leakage.
