NOTE:
• The schrader valve is inside the
charging port.
2. Connect the other charge hose of
manifold valve to the vacuum pump.
3. Fully open the Low Side handle of the
manifold valve.
4. Operate the vacuum pump to evacuate.
After starting evacuation, slightly loose
the flare nut of the Low Side valve on
the gas pipe side and check if the air is
entering (Operation noise of the vacuum
pump changes and a compound meter
indicates 0 instead of minus), then
tighten the flare nut. The procedure
verifies if there are blocks inside the
tubes.
5. Make evacuation for 15 minutes or
more and check that the compound
meter indicates -7-3/5 x 10 Microns
Hg (-1x10 Pa). After the evacuation is
completed, fully close the Low Side
handle of the manifold valve and stop
the operation of the vacuum pump.
6. Turn the stem of the packed valve B
about 45 o counter clockwise for 6~7
seconds after the gas comes out, then
tighten the flare nut again. Make sure
the pressure display in the pressure
indicator is a little higher than the
atmospheric pressure. This procedure
verifies if the refrigerant goes through
the tubes correctly.
7. Close the schrader valve, then remove
the valve core tool. Replace the
charging port cap.
8. Fully open the packed valve stems B
and A.
9. Securely tighten the cap of the packed
valve.

4. TEST AND RUNNING
4.1 Gas Leakage Check
1. Soap water method
• Apply a soap water or a liquid neutral
detergent on the indoor unit connection
or outdoor unit connections (A: Low
side valve, B: High side valve, C and
D are ends of indoor unit connection)
by a soft brush to check for leakage
of the connecting points of the piping.
If bubbles come out, the pipes have
leakage point.
