(Continued) 2. Mounting of compressor
1) Mount the compressor in the reverse procedure
for removal.
NOTE
• After replacement of the compressor, be sure to
replace the compressor lead. (Repair part code of
compressor lead: 43160612)
In this time, wrap the ferrite core with the
compressor lead wire by 1 time.
• As shown in the right figure, mount the sound-
insulation plate (rolling in, rolling out) by passing
through it between the compressor and the piping,
and between the piping and the partition board.
• Fix TD sensor by the bundling band for heatproof
on the market via the pipe cover so that TD sensor
does not directly come to contact with the
discharge pipe.
3. Vacuuming
1) Connect the vacuum pump to the charge port and
the check joint of the gas pipe valve and then drive
the vacuum pump.
2) Carry out vacuuming until the vacuum low
pressure gauge indicates 1 (mmHg).
NOTE
Before vacuuming, open PMV fully.
If PMV is closed, vacuum may be impossible between
liquid pipe valve and PMV of the outdoor unit.
Forced full-opening method of PMV
• Turn on the leakage breaker.
• Turn on 1 and 3 of Dip switch SW804 on the control
P.C. board of the outdoor unit.
• Keep pushing SW801 on the control P.C. board of
the outdoor unit for 1 second or more.
• After pushing SW801 for 1 second or more, turn off
the leakage breaker within 2 minutes.
4. Refrigerant charge
1) Add the refrigerant amount determined by the pipe
length from the charge port of the valve.

Wrap the ferrite core with the compressor
lead wire for 1 time.
There should be no clearance between
sound-insulation plate (upper) and sound-
insulation plate (rolling out).
