Points
(R8103)
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 operating and
the stop valve open, air may
be sucked in to generate an
(R8104)
over-pressure in refrigeration
cycle, thus resulting in pipe
rupture or accidental injury.
Place a plastic sheet 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.
(R8101)
Carry out the removal works
with 2 wrenches.
When the pipings are
disconnected, protect the
both openings of pipe side
and unit side from entering
of moisture.
