before disassembling work.
Step
Procedure
Points
Conduct pump-down
operation.
Warning
If refrigerant leaks, repair the
leak location, then collect all
refrigerant from the unit.
Conduct vacuum drying, and
charge proper amount of
refrigerant.
Warning
Do not mix any gas (including
air) other than the specified
refrigerant (R-22) into
refrigerating cycle.
(Mixing of air or other gas
causes abnormal
temperature rise in
refrigerating cycle, and this
results in pipe rupture or
personal injuries.)
Pay attention so that the
residual drain does not
make the floor wet.
In case that a drain hose is
buried inside a wall, remove
it after the drain hose in the
wall is pulled out.
1
Remove the 1 screw.
2
Remove the drain hose.
Make curing so that the
residual drain water
does not leak out.
3
Disengage the
insulation tube and
disconnect the flare
nuts for the gas piping
and the liquid piping.
Use two wrenches to
disconnect the pipings.
After pipes are
disconnected, close all pipe
openings with caps to
prevent dust and moisture
from entering pipes.

unit from the installation
plate.
