Preparations for starting
Check the following before starting the compressor for the first time after installation:
•
that the oil level is at the middle of the sight glass. If this is not the case, recharge with
oil. See section
4.12 Compressor prelubrication
.
•
that the safety equipment is set correctly. All safety functions are factory-set. This is the
case for both analogue control and UniSAB control.
•
that the heating element in the crankcase has been energised 6-8 hours before starting
up the compressor.
•
that the pilot voltage is switched on. Check that the emergency stop button is in ON-po-
sition (the button must be in its outermost position). If the plant does not start, check
that the fuses are intact.
•
that the valves are open according to Table 6.
•
that direction of rotation is correct. Check this by starting the motor and turning it off
again immediately.
At
fixed speed
, check the direction of rotation before mounting the coupling intermedi-
ate part.
At
VSD operation
, make the check with the entire coupling mounted, but run the motor
for maximum 1 second. It is a good idea to have someone else help observe the direc-
tion of rotation.
Note:
On delivery, the compressor is fitted with a fine-meshed filter bag in the suction filters.
The filter bag filters off any small rust particles, which may penetrate the suction filters, and
thus effectively ensures that no impurities are mixed with the oil. The filter bag must not be
used for more than 50 hours after the first compressor start-up. This also applies to situations
where modifications that may cause impurities in the suction gas are performed on the plant.
After 50 hours, the filter bag and the insert must be removed and discarded. Disposal of used
filter bags must be carried out according to the existing environmental legislation. Please read
the Final disposal chapter.
