according to "Removal of
Drain Hose".
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 running and the
stop valve being open, air
may be sucked in and cause
an over-pressure in
refrigeration cycle, thus
resulting in pipe rupture or
accidental injury.
Be careful that remaining
drain will not wet the floor.
If the drain hose is
embedded in the wall,
disconnect the drain hose
beforehand.
Carry out the removal works
with 2 pair of spanners.
