– Fit the cap (Fig. 25/2), and fix by screw (Fig. 25/1).
6. Adjusting the motor running time.
WARNING
The motor running time must be adjusted by an Authorized
Specialist.
The motor running time shall be checked and, where applicable,
corrected on initial commissioning.
– The motor min. running time (switch cycles/h) has been factory–set,
and must not be changed.
WARNING
The min. off–load time of the motor has been set at 60 s in the
factory. If required, this time can be increased by re–adjusting the
potentiometer .
– The star–delta transfer time can be adjusted between 2 and 10 s.
Transfer time to be adjusted such that motor has reached rated speed
on transfer from star phase to delta phase.
Adjustment of min. off–load time and star–delta transfer time:

7. Commissioning after transport of compressor.
WARNING
Coolant may have entered the coolant separator cartridge in
transit.
Operate the compressor for approx. 10 min under idling control
during initial commissioning.
– Mount stop valve at the compressed–air discharge, and close the
valve.
– Start the compressor and operate in continuous operation.
STARTING
WARNING
The compressor is to be operated with closed enclosure.
The enclosure may only be opened short time for minor setting
work with running machine.
Full noise damping effect will only be achieved with closed
enclosure.
Check coolant levels before every start–up.
Ensure prior to start–up that nobody is inside the compressor
danger area.
