5.Purging Method:To use vacuum pump

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.

Tube(for R410A)

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.

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.

2.Please do not let other cooling medium, except specified one (R410A),

  or air enter into the cooling circulation system. Otherwise, there will be

 abnormal high pressure in the system to make it crack and lead to

  personal injuries.

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
