Preparation
Be sure to stop the
compressor before
disconnecting the refrigerant
pipe. If the refrigerant pipe is
disconnected with the
(R17298)
compressor running and the
stop valve opened, air may be
sucked in to generate an
over-pressure in the
refrigeration cycle, thus
resulting in pipe rupture or
accidental injury.

Drain hose
(R17300)
From the viewpoint of global
environmental protection,
make sure to use a vacuum
pump for air purging.

Points
Remove the electrical box
according to the "Removal
of Electrical Box / Vertical
Blades".
Caution
If the drain hose is
embedded in the wall,
disconnect the drain hose
beforehand.
Place a plastic sheet under
the drain hose as remaining
drain may leak.
Carry out the removal work
with 2 wrenches.
Caution
When the pipings are
disconnected, protect the
both openings from entering
moisture.
