Purging Method:(For R407C)

Detach the service port's cap of 3-way valve, the valve rod's cap for 2-way valve and 3-way's, 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, operate

vacuum pump. If the scale-moves of gause (low)

 

reach vacuum condition in a moment, check

again.

Vacuumize for over 15min. And check the level gauge which should read -0.1 MPa (-76 cm Hg) at low pressure side. After the completion of vacuumizing, close the handle 'Lo' in gaugemanifold and stop the operation of 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, the return to the beginning of

Open the valve rod for the 2-way valve to an angle of anticlockwise 90 degrees.

After 6 seconds, close the 2-way valve and make the inspection of gas leakage.

No gas leakage?

In case of gas leakage, tighten parts of pipe connection. If leakage stops, then proceed steps.

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

2-way valve and 3-way. Turn the valve rod anticlockwise until hitting lightly.

To prevent the gas leakage, turn the service port's cap, the valve rod's cap for 2-way valve and 3-way's a little more than the point where the torque increases suddenly.

After attaching the each caps, check the gas leakage around the caps.

CAUTION:

1.If the refrigerant of the air conditioner leaks, it is necessary to discharge all the refrigerant. Vacuumize first, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate.
