24. CONTROL AND FIRST
START-UP
24.1. PREPARATION FOR COMMISSIONING
Bear in mind that a free start-up service is
offered by the Aermec Technical Service
for the unit of this series, at the request of
Aermec customers or legitimate owners
and in ITALY only.
The start-up must be previously agreed on
the basis of the system implementation
times. Before the intervention of the AERMEC
After Sales Service, all the operations
(electrical and hydraulic hook ups, loading
and breather from the system) must be
completed.
Before starting the unit make sure that:
− All the safety conditions have been
respected
− The unity has been properly fixed to the
support base
− The minimum technical spaces have
been observed;
− Water connections have been
performed respecting the input and
output
− The hydraulic system has been loaded
and vented.
− The hydraulic circuit taps are open
− The electrical connections have been
properly carried out;
− The voltage is within a tolerance of 10%
of the unit nominal voltage
− The earthing has been carried out
correctly
− Tightening of all electrical and hydraulic
connections have been well carried
out.

of the compressor is less than the
maximum indicated in the technical
data table.
− Check in the models with
three-phase supply power that the
noise level of the compressor is not
abnormal, in this case invert a phase.
− Make sure that the voltage value
are within the prefixed limits and
that the displacements between
the three phases (three-phase
supply power) do not get above 3%.
