VACUUM & CHARGE THE REFRIGERANT

Take out the filter, remove the rear plate.

Connect the copper tube of compressor, quick

coupler, fixing value, vacuum pump and refrigerant

bottle. (Please refer to the drawing shown at right.)

Weigh the refrigerant amount by an electronic scale,

write down the amount.

Open the valve A & B of the fixing valve. Close the

valve of the refrigerant bottle, then open the vacuum

pump.

After 20 – 30 minutes, when the vacuum density is

higher than 133Pa, close the valve A of the fixing

valve, then close the vacuum pump.

Open the valve of refrigerant bottle first, then open

valve B of fixing valve slowly, the refrigerant will enter

the cooling system then.

When the charging amount is equal to the amount

mentioned in the rating label, close valve B of fixing

valve and valve of refrigerant bottle immediately.

Tong the charging tube between the compressor and

quick coupler completely. Notice! The charging tube

must be closed completely, otherwise, the refrigerant

will leak out.

Take off the quick coupler. Clamp the end of charging

tube flat

10. Soldering the end of the charging tube (which you

clamped it flat previously) to prevent it from leakage.

HOW TO DETECT THE LEAKAGE OF REFRIGERANT?

Wipe the soap water of high density on the soldering

parts of the cooling system and the other parts which

are easy to have leakage.

The soap water will bubble when there is a leakage.

Notice! When the leakage is found, do not solder it

directly.

If no leakage is found by the soap water, it only

means there is no major leakage on the cooling

system. You may use a professional detector to

detect it again.
