EVACUATION PROCEDURES

Connect the refrigerant pipes (both the liquid and gas pipes)

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 capon).

Connect the gage manifold valve and the vacuum pump to the service port

of the stop valve on the gas 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 -0.1Mpa (-76cmHg).

Check the vacuum with the gage manifold valve, then close the gage manifold valve,

Leave it asis for one or two minutes. Make sure the pointer of the

gage manifold valve remains in the same position.
