(12). When installing or relocating the system, be sure to keep the refrigerant circuit free from
substances other than the specified refrigerant (R410A), such as air. (Any presence of air or
other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture,
resulting in injury.)
(13).
During pump-down, stop the compressor before removing the refrigerant piping. If the
compressor is still running and the stop valve is open during pump-down, air will be sucked in
when the refrigerant piping is removed, causing abnormal pressure i n the freezer cycle which
will lead to breakage and even injury.
(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.
(15).
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.
(16).
Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may
result in electric shocks, or fire.
