7.1 First commissioning
Danger
Make sure before commissioning that nobody is in
the danger zone of the screw compressor.
Only operate the screw compressor with closed
access panels.
Important
Although every Gardner Denver screw compressor
has been subjected to a test run at the factory and
has again been thoroughly inspected before
shipment, damage during shipment cannot be
excluded. For this reason, every screw compressor
should be checked once again for damage before
being commissioned. In addition, it should be
observed during the first operating hours.
If the screw compressor is newly connected to a
power supply, check the direction of rotation of the
drive motor!
First commissioning is carried out as follows:

Remove transport guards (see chapter 6.4, Fig. 12)

Fill oil in the pressure vessel up to “maximum oil
level” mark. (This applies to compressor systems
which are delivered without having been filled with
oil). (Refer to Chapter 9.4 and 9.15 for information
on filling oil).

Check the oil level in the pressure reservoir (see
also chapter 6.5). (Fig. 14)

Check the setting of the control-power transformer
(see also chapter 6.3). (Fig. 14)

Check and re-tighten all connecting terminals of the
electrical control.

Open isolator valves between the screw compres-
sor, reservoir and pipe.

Operate main power supply switch.

Once the power supply has been switched on, the
POWER LOSS
fault appears. This fault must be
acknowledged using the key (Fig. 16). You will
find more information about the control in chapter 8.

The factory setting of the setpoint value for the
network pressure (upper and lower switching point)
is saved in the compressor control GD PILOT and
depends on the relevant pressure variant of the
compressor (see nameplate fig.1, stage pressures =
maximum operating pressure). Chapter 8.5.2
describes how you check these settings or change
the values.

Temporarily open the hood to check the direction of
rotation, for specified direction, see (- 1 - Fig. 15)
Important
If the direction of rotation is incorrect, immediately
shut down the unit using the large emergency
STOP button on the control panel (-24- Fig. 2) and
not using the


key (Fig. 16), as otherwise you may
cause serious damage to the compressor, even if
only operated briefly.
The access panels may temporarily be opened for
checking the direction of rotation (wear ear
protectors).
Danger
Beware of rotating parts!
Rotating parts can lead to injuries. Stay at a safe
distance away from rotating machine parts!
Press the START button

I
(- 2 - Fig. 16) and
check the direction of rotation. With a wrong direction
of rotation, press the red emergency STOP button
(-24- Fig. 2) immediately and correct the direction of
rotation.

Note
For switching the compressor off “normally”, use only
the stop push-button

(Fig. 16), but not the
EMERGENCY STOP push-button (-24- Fig. 2). After
having been switched off, the compressor is aftercooled
for 30 seconds (soft stop).
