Compressor Application Manual

totally empty, switch on the

resistance of the charge cylinder to

increase the pressure and release

the refrigerant to the refrigeration

system. If it is not possible to

increase the pressure in the charge

cylinder through the resistance,

you may lock the register of the

charge cylinder, switch the

compressor on and then slowly

open it until the correct refrigerant

charge is transferred.

This operation requires that the

refrigeration professional takes

great care. In the case of

excessive refrigerant fluid, the

compressor may draw in the liquid

refrigerant fluid and break the

cylinder joints or other components.

Any fault will detract from the

system's good performance.
