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 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.
D800
