6 Compressor
Compressor lead 2. Attach the compressor
1) Attach the compressor in the reverse order of the
removal.
Note)
• Be sure to replace the compressor lead after the
compressor replacement. (Compressor lead
spare parts code: 43160591)
At this time, wind the ferrite core with the
compressor lead for 4 times.
• Attach the soundproofing board (Inward
winding, Outward winding), as shown in the right
figure, through between the compressor and
between the piping and parting board.
• Fix the TD sensor with a commercially available
heat resistant binding tie through the piping
cover so that the sensor do not contact the
discharge pipe.
3) Vacuuming
1) Connect the vacuum pump to the charge port and
check joint of the gas piping valve to operate the
vacuum pump.
2) Perform vacuuming until the vacuum low pressure
gauge shows 1(mmHg).
Note)
Open fully the pulse motor valve before
vacuuming. With the valve closed, vacuuming
between the outdoor unit liquid valve and the pulse
motor valve may fail.
How to make pulse motor valve forcible full open
• Turn on the electric leakage breaker.
• Set the SW804 dip switch 1 and 3 on the outdoor
unit control board to ON.
• Press SW801 on the outdoor unit control board
for 1 second or longer.
• After pressing SW801 for 1 second or longer,
turn off the electric leakage breaker within 2
minutes.
4. Charge refrigerant
1) Add refrigerant whose amount is defined
according to the piping length from the valve
charge port. (HWS-1102H, 1402H : 2.7kg)
No.
