between the indoor and the outdoor units.
Remove the service port cap of the stop valve on the side of the outdoor unit gas pipe.(The stop valve will not
work in its initial state fresh out of the factory (totally closed with cap on))
When vacuuming
Connect the gage manifold valve and the vacuum pump to
the service port of the stop valve on the liquid pipe side of the
outdoor unit.
Run the vacuum pump for more than 15 minutes and at this
time confirm that the pressure gage indicates – 0.1 Mpa.
Check the vacuum with the gage manifold valve, then close
the gage manifold valve, and stop the vacuum pump.
