Installation guide

(1) Connect a refrigerant box to the manifold gauge.

(2) Since oxygen exists in the hose between the gauge manifold and the refrigerant box, open the

refrigerant box valve to purge oxygen from the hose.

(3) Place the refrigerant box on top of the electronic scale.

(4) If it is a commercial product (sales with 11kg), then turn the refrigerant box upside down to

place it on top of the electronic scale. If the refrigerant box type is chargeable (multiple use),

then you don’t need to turn it upside down as long as the gauge manifold is connected to the

liquid valve of the refrigerant box. If not connected, then turn it upside down before placing it on

the electronic scale.

The reason is because you want to inject liquid refrigerants.

3) Inject the amount of refrigerant calculated above.

(1) Open the gauge manifold and check the amount of refrigerant injection.

(2) If entire refrigerant flows in smoothly, then turn off the valve and separate the gauge manifold

from the system.

(3) If the pipe is too long and entire refrigerant can’t be injected, then perform cooling operation to

gradually inject the refrigerant.
