Commissioning

6.1 Preparation for commissioning

The components of the screw compressor air end 

system are carefully checked and tested at the 

factory. These tests ensure that the required per-

formance and checking data are complied with. 

Nevertheless, the screw compressor air end sys-

tem should be observed during the initial operating 

hours.

Before commissioning, it must be checked 

whether the screw compressor air end system has 

been properly installed.

As it is probable that there is no oil in the feed 

chamber following transport and storage, 0.53 to 

2.1 quarts (0.5 to 2 liters) of clean oil of the speci-

fied oil quality must be added to the system before 

initial start-up in dependence on the screw com-

pressor air end size and the system. This prevents 

the rotors from running dry during starting.

Caution:

With regard to commissioning, the applicable reg-

ulations of the specific country must be observed. 

In Germany these include the Operating Safety 

Ordinance.

The following points must be observed prior to ini-

tial commissioning:

– Be sure to observe the direction of rotation (see 

chapter 6.2 "Checking direction of rotation").

– The final pressure specified on the nameplate 

may not be exceeded.

– Do not switch off screw compressor air end 

systems running under load at the Emergency-

Stop or main switch. 

– Check the oil level. 

– Before each initial commissioning and when 

recommissioning after a longer shut-down of 

the screw compressor air end system, always 

carry out the activities described in chapter 6.4 

"Recommissioning screw compressor air end 

system".

– With a belt drive: check the belt tension and belt 

routing (see chapter 7 "Maintenance").

– Check the position of the shut-off valve.

– Check all screw fitting and fastening screws for 

firm seating.

Caution:

– Commissioning is only allowed when the sys-

tem is complete (Danger from being pulled into 

the screw, hot oil and compressed air escap-

ing).

6.2 Checking direction of rotation 

Direction of rotation:

Standard model 

rotating to the left 

(counter-

clockwise) looking at the shaft.

The design with a transmission 

rotates to the 

right 

(clockwise)

Caution:

The direction of rotation of the screw compressor 

air end must be checked during initial commission-

ing and each time changes are made to the elec-

trical supply line of the electric motor drive. For this 

purpose, switch on the drive motor briefly and then 

switch off again immediately. 

An incorrect direction of rotation for more than 

2 seconds will result in destruction in the screw 

compressor air end. Reconnect the phases of the 

connection cable if necessary.

6.3 Test run

Caution:

The system is discharged extremely quickly down 

to the opening pressure "minimum pressure valve" 

in the Stop mode, "with shut-off valve opened"! 

This can result in the oil in the separating tank 

foaming up.

The possible consequences include:

– Oil escaping with the discharge air

– Oil flooding the fine separator cartridges

– Compressed air containing oil when 

restarting the system

Therefore, the following points must be observed 

during the test run: 

– Only switch off the system with the shut-off 

valve closed!

– If possible, connect the system to a com-

pressed-air reservoir!

Caution:

Maintain appropriate safety distance.

There is a risk of injury if the rotors are blocked.

For safety reasons, only drive for a few seconds 

during initial startup.

For safety reasons, operation in open state must 

not be carried out.

Wear ear protection.
