1. Remove the valve caps on
the liquid valve and gas
valve and the nut of refri-
gerant charging vent.
2. Connect the charging ho-
se of piezometer to the
refrigerant charging vent
of gas valve and then co-
nnect the other charging
hose to the vacuum pump.
3. Open the piezometer com-
pletely and operate for
10-15min to check if the
pressure of piezometer re-
mains in -0.1MPa.
4. Close the vacuum pump
and maintain this status for
1-2min to check if the pres-
sure 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
