Installation Procedure
Detach the service port's cap of gas stop valve, the valve rod's cap for liquid
stop valve and gas stop valve, and connect the service port into the projection
of charge hose (low) for gaugemanifold. Then connect the projection of
charge hose (center) for gaugemanifold into vacuum pump.
Open the handle at low in gaugemanifold, and operate vacuum pump. If the
scale-moves of gause (low) reach vacuum condition in a moment, check
the step 1 again.
Vacuumize for over 15min. And check the level gauge which should read -
0.1MPa (-76 cm Hg) at low pressure side. After the completion of vacuumizing,
close the handle 'Lo' in the vacuum pump. Check the condition of the scale
and hold it for 1-2min. If the scale-moves back in spite of tightening, make
flaring work again, then return to the beginning of the step 3.
Open the valve rod for the liquid stop valve to an angle of anticlockwise 90
degree. After 6 seconds, close the liquid stop valve and make the inspection
of gas leakge.
No gas leakage? In case of gas leakage, tighten parts of pipe connection. If leakage stops, then proceed the step 6. If it
does not stop gas leakage, discharge whole refrigerants from the service port. After flaring work again and vacuumize,
fill up prescribed refrigerant from the gas cylinder.
Detach the charge hose from the service port, open liquid stop valve and
gas stop valve. Turn the valve rod anticlockwise until hitting lightly.
To prevent the gas leakage, turn the service ports cap, the valve rodis cap
for liquid stop valve and gas stop valve a little more than the point where
the torque increases suddenly.
If the refrigerant of the air conditioner leaks, it is necessary to make all the refrigerant out. Vacuumize first, then charge
the liquid refrigerant into air conditioner according to the amount marked on the nameplate.
