Caution
In pump-down work, be sure
to stop the compressor
before disconnecting the
refrigerant pipe. If the
refrigerant pipe is
disconnected with the
compressor being operated
and the stop valve being
open, air may be sucked in to
(R10323)
generate an over-pressure in
refrigeration cycle, thus
resulting in pipe rupture or
accidental injury.
Place a plastic bag under
the drain pan to prevent
from wetting the floor with
remaining drain.
If the drain hose is
embedded in the wall,
disconnect the drain hose
beforehand.
(R10324)
Carry out the removal works
with 2 pair of spanners.
When the pipes are

both openings of pipe side
and unit side from entering
of moisture.
