Compressor Application Manual

To complete the cleaning operation, proceed as

follows:

• Place a fast coupling on the return line

and connect it on the cleaning machine's

outlet side;

• Connect the capillary to the

cleaning machine’s suction

side, leaving it operating

for around 15 minutes;

• Blast some nitrogen

into this circuit to

remove any cleaning

fluid residue.

Lastly, the condenser

must be cleaned. To do so,

you must repeat the previous

operation, connecting one end of the condenser to

the outlet side and the other to the cleaning

machine's suction tube.

5 - Installation of filter drier

• Make a small bend in the capillary to

prevent it from going too far into the filter,

approximately 15 mm (0.59”);

• Using a clamp, open up the two sides

of the filter drier when brazing;

the filter drier

If it is not possible to use a blowtorch with

proper capacity to braze the oil cooler tubes

(TRO) in the system's tubes, proceed as follows:

before placing the compressor in the refrigeration

system, tip it to the opposite side from the TRO,

braze approximately 50 mm (1.97”) copper

tube at each end of the TRO. With the TRO

extended, it will certainly not be

difficult to braze it onto the

system's tubes.

Only use filters that

contain molecular sieve

desiccants inside.
