1. Detachment
WARNING
When removing the brazing part of the suction /
discharge pipe of the compressor, remove the brazing
part in a wellventilated place after recovering the
refrigerant.
If recovery is insufficient, the refrigerant and refrigerating
machine oil may blow, causing injury.
1) Recover refrigerant gas.
2) Following to work of Detachment of (1) and (4).
3) Remove the piping panel (front).
Remove the screws from piping panel (front) and
base plate. (2 pcs, M4 × 10 hexagon screws)
Remove the screw from the piping panel (front) and
piping panel (rear).
(1 pc, M4 × 10 hexagon screw)
4) Remove the piping panel (rear). Remove the screws
on the piping panel (rear) and the bottom plate.
(2 pcs, M4 × 10 hexagon screws)
5) Remove the valve fixing plate.
Remove the screw for the valve fixing plate and
partition plate. (1 pc, M4 × 8 truss screw)
Remove two bolts at liquid valve side and valve
fixing plate. (2 pcs, M6 × 15 deltite screws)
Remove two bolts at gas valve side and valve fixing
plate. (2 pcs, M6 × 15 deltite screws)
6) Remove the pipe cover and TD sensor fixed with the
discharge pipe
7) Remove the sound insulation board (upper, inner,
and outer).
8) Remove the compressor’ terminal cover (two claws)
and compressor lead wires and compressor case
thermostat (one claw).
9) Cut the cable-tie fixing the inverter box (two
positions) and the other cable-tie rolled around the
compressor lead wires.
10)Remove the connector for the compressor lead
wires to remove the compressor lead wires. (Keep
the ferrite core attached to the electric parts box.)
11)Remove the discharge and suction pipes connected
to the compressor using a burner.
WARNING
Ensure extreme caution when removing piping by
melting the weld with a burner as fire may result if there
is any oil within the piping.
NOTE
Carefully avoid contact with the 4-way valve and PMV
with the flame (could result in a malfunction).
12)Remove the refrigeration cycle discharge and
suction pipes by pulling them upwards.
13)Remove the compressor nuts securing the
compressor to the base plate. (H13 × 3 nuts)
14)Pull the compressor forwards.
NOTE
The compressor weighs at least 15 kg. Ensure two
