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. Close Check the condition of the scale and hold it for 1-2min. If the scale-moves back in spite of tightening, make

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.

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:

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

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.
