6.4 Evacuation

First evacuate the

system

and then include

the compressor in the evacuation process.

  Relieve the compressor pressure.
  Open the suction and pressure line shut-off valves.
  Turn on the oil sump heater.
  Evacuate the suction and discharge pressure sides using the vacuum pump.
  The vacuum has to be broken with nitrogen several times between the evacuation.
  At the end of the evacuation process, the vacuum should be < 1.5 mbar when the pump is switched off.
  Repeat this process as often as is required.

Make sure that the suction and pressure line shut-off valves are open.

6.5 Refrigerant charge

Filling the liquid refrigerant: It is recommended that the system first be filled at standstill
with gas on the high-pressure side up to a system pressure of at least 5.2 bar (if it is filled
below 5.2 bar with liquid, there is a risk of dry ice formation). Further filling according to

system.

To eliminate the possibility of dry ice formation when the system is operating (during and

after the filling process), the shut-off point of the low-pressure switch should be set to a

value of at least 5.2 bar.

A refrigerant supplement, which may become necessary after start-up, can be topped up

in vapour form on the suction side.

ATTENTION

Do not start the compressor if it is under vacuum. Do not apply
any voltage - even for test purposes (must only be operated with
refrigerant).

Under vacuum, the spark-over and creepage current distances of the

terminal board connection bolts shorten; this can result in winding and

terminal board damage.

ATTENTION

Avoid overfilling the machine with refrigerant

!

Do not charge liquid refrigerant into the suction-side on the

compressor.

Do not mix additives with the oil and refrigerant.

CAUTION

Wear personal protective clothing such as goggles and protective
gloves!

WARNING

Never exceed the max. permissible pressures while charging.
Precautions must be taken in time.
