7. Preparations for commissioning
30
The control-power transformer is factory-preset to the
rated voltage. However, practice has shown that the
actual supply voltage often differs from this value.
Before first commissioning, set the measured supply
voltage on the control transformer. Fig. 14 illustrates an
example.
Following first commissioning, the setting of the control
transformer must be inspected while operating under
load and corrected where necessary. (see Section 10.9).

Checking the Oil Level
DANGER
Air/oil under pressure will cause severe
personal injury or death.
•
Shut down the compressor, relieve the
system of all pressure, disconnect,
lockout and tagout the power supply to
the compressor package before
removing valves, caps, plugs, fittings,
bolts and filters.
CAUTION
Fire hazard and slip hazard!
•
Do not spill any oil!
•
Look for leaks! Immediately take care of
any spilled oil!
NOTICE
Do not mix oils with different specifications.
If the compressor system is delivered without
oil, oil must first be filled into the pressure
reservoir up to the “maximum oil level” mark.
(For oil filling also see Sections 10.4 and 10.14)

2 Oil-level indicator
3 Maximum oil level
4 Minimum oil level
Check the oil level as follows:
•
Shut off the compressor with the STOP button.
•
Wait at least 5 minutes until the oil has settled, i.e.
until the air has bubbled out.
•
The oil level should be checked at each pause in
operation and at regular intervals using the
transparent plastic tube on the pressure reservoir
(- 2 - Fig. 15).
•
The oil level must lie between the “maximum oil
level” (- 3 - Fig. 15) and “minimum oil level”
(- 4 - Fig. 15) marks on the oil container.
•
If required, top up oil. Use Gardner Denver oil only.
•
Close the oil filler cap (-1- Fig. 15) firmly.
Also see Section 10.14 “Service and Maintenance.”

Sound pressure level
Sound pressure levels are measured according to
ISO 2151 at full load at an 11-yard distance dB(A)
(tol/- 3 dB(A))
