Commissioning
The pressure equipment was tested in the factory as a
single unit. After installation, the tightness of the con-
nections and of the piping system must be tested
again.
5.1
Charging with oil
OA1854(A) .. OA25012(A), OA1954(A) .. OA25112(A)
Fill the entire oil charge of the system at the oil fill con-
nection of the oil separator.
Oil quantity:
• operating charge of the oil separator
• plus the entire oil quantity circulating in the system
(e.g. oil cooler, oil line)
OAS322 .. OAS3088, OAF6288 .. OAF15211
Prefill oil operating charge in secondary oil separator
(OAHC: in tertiary oil separator).

5.2
Checking tightness
Check the refrigerant circuit (assembly) for tightness,
as a whole or in parts, according to EN 378-2 (or other
applicable equivalent safety standards). For this, create
an overpressure, preferably using dried nitrogen.
DANGER
Risk of bursting due to excessive pressure!
The pressure applied during the test must never
exceed the maximum permitted values!
Test pressure: 1.1-fold of the maximum allow-
able pressure (see name plate). Make a distinc-
tion between the high-pressure and low-pres-
sure sides!
5.3
Evacuation
• Switch on the oil heater.
• Open all shut-off valves and solenoid valves.
• Use a vacuum pump to evacuate the entire system,
including the compressor, on the suction side and
the high pressure side.
With the vacuum pump shut off, a "standing vacuum"
lower than 1.5 mbar must be achieved.
• Repeat the operation several times if necessary.
