Installation of Outdoor unit
Step 7: Vacuum pumping
Use vacuum pump
1 . Remove the valve caps on the liquid valve and
gas valve and the nut of refrigerant charging
vent.
2 . Connect the charging hose of piezometer to
the refrigerant charging vent of gas valve and
then connect the other charging hose to the
vacuum pump.
3 . Open the pizeometer completely and operate
for 10~15min to check if the pressure of
piezometer remains in -0.1MPa.
4 . Close the vacuum pump and maintain this
status for 1~2min to check if the pressure of
piezometer remains in -0.1MPa. If the pressure
decreases, there may be leakage.
5 . Remove the piezometer, open the valve core
of liquid valve and gas valve completely within
inner hexagon spanner.
6 . Tighten the screw caps of valve and refrigerant
charging vent.
7 . Reinstall the handle.
Step 8: Leakage detection
1. With leakage detector:
Check if there is leakage with leakage detector.
2. With soap water:
If leakage detector is not available, please use soap water for leakage detection.
Apply soap water at the suspected position and keep the soap water for more than
3min. If there are air bubbles coming out of this position, there,’s a leakage.
