The start of operation must be scheduled in advance
based on the timeframe for the completion of works
for the system. Prior to the work to be carried out
by the AERMEC service personnel, all other works
(electrical and hydraulic hook-ups, priming and
bleeding of air from the system) must have been
completed.
Before starting the unit make sure that:
All safety conditions have been
1.
respected
The unit is correctly fixed to the support
2.
surface
3.
The minimum technical spaces have
been respected;
The hydraulic connections have been
4.
made respecting the inlet and outlet
5.
The hydraulic plant has been loaded and
bled.
6.
The hydraulic circuit cocks are open
The electric connections have been

functioning limits lie within the limits.
- Check that the compressor input current is lower
than the maximum indicated in the technical data
table.
- Check, that in models with three-phase power
supply, that the compressor noise level is not
abnormal. If this is the case, invert a phase.
- Make sure that the voltage value lies within the
pre-fixed limits and that unbalance between the
three phases (three-phase power supply) is not
above 3%.
