1) Completely tighten the flare nuts of the indoor
and outdoor units, confirm that both the 2-way
and 3-way valves are set to the closed
position.
2) Connect the charge hose with the push pin of
handle lo to the 3-way valves gas service port.
3) Connect the charge hose of handle hi
connection to the vacuum pump.
4) Fully open the handle Lo of the manifold
valve.
5) Operate the vacuum pump to evacuate.
6) Make evacuation for 30 minutes and check
whether the compound meter indicates -
0.1Mpa. If the meter does not indicate -
0.1Mpa after pumping 30 minutes, it should
be pumped 20 minutes more. If the pressure
can’t achieve -0.1Mpa after pumping 50
minutes, please check if there are some
leakage points.
Fully close the handle Lo valve of the manifold
valve and stop the operation of the vacuum pump.
Confirm that the gauge needle does not move
(approximately 5 minutes after turning off the
vacuum pump).
7) Turn the flare nut of the 3-way valves about
45° counterclockwise for 6 or 7seconds after
the gas
coming out, then tighten the flare nut again. Make
sure the pressure display in the pressure
indicator is a little higher than the atmosphere
pressure. Then remove the charge hose from the
3 way valve.
8) Fully open the 2 way valve and 3 way valve
and securely tighten the cap of the 3 way
valve.
4.7 Evacuation after servicing the outdoor
unit refrigeration circuit
1. Evacuation of the complete refrigeration
circuit, Indoor and outdoor unit.
Procedure:
1). Confirm that both the 2-way and 3-way valves
are set to the opened position.
2). Connect the vacuum pump to 3-
way valve’s
service port.
3). Evacuation for approximately one hour.
Confirm that the compound meter indicates -
0.1Mpa (500 Microns / 29.9 in,hg).
4). Close the valve (Low side) on the charge set,
turn off the vacuum pump, and confirm that the
gauge needle does not move (approximately 5
minutes after turning off the vacuum pump).
5). Disconnect the charge hose from the vacuum
pump.
2. Refrigerant charging
Procedure:
1). Connect the charge hose to the charging
cylinder, open the 2-way valve and the 3-way
valve.
Connect the charge hose which you disconnected
