NOTE
(continued)
• Also ensure to replace the compressor lead after
replacing the compressor. (Compressor lead
replacement code: 43160658)
At this time please ensure to wind the compressor lead 4
times around the ferrite core.
(Ensure to position the ferrite core the same as when
before removed.)
• Install the sound insulation board (inner and outer)
through the space between the compressor and the
piping, and between the pipes and separate plate as
shown on the right.
• Fix in place with commercially available heat-resistant
code clamps through the pipe cover so that the TD
sensor lead does not come in direct contact with the
discharge pipe.
3. Vacuum
1) Connect the vacuum pump to the charge port of the
liquid and gas pipe valves and the check joint on the
high pressure side, and then operate the vacuum
pump.
2) Vacuum until the vacuum low pressure gauge reaches
1 (mmHg).
NOTE
Fully open the electronic control valve before the vacuum
process. If closed the vacuum pipe between the liquid pipe
valve and electronic control valve of the outdoor unit may
not be able to be drawn through.
Method for forcibly fully opening the electronic control valve
• Turn on the power supply breaker.
• Ensure that D805 of the LED indication of the outdoor
unit is lit up. If D805 is not lit up (off or flashing) then
push and hold down SW01 and SW02 at the same time
for at least 5 seconds and check that D805 lights up.
• Push and hold SW01 down for at least 5 seconds or to
confirm that D804 is slowly flashing (once/second).
• Push SW01 several times until the LED indications
(D800 to D804) become the following.
• Push SW02 and D805 will start rapidly flashing.
D800
: Go ON,
• Push and hold SW02 down for at least 5 seconds and
D804 will start slowly flashing. Once D805 lights up the
PMV will start to open.
After 30 seconds turn off the power breaker.
4. Refrigerant encapsulation
1) Add the amount of refrigerant determined by the pipe
length using the charge port of the valve.
