22. CONTROL AND FIRST START-UP
22.1. 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.
22.2. FIRST COMMISSIONING OF THE MACHINE
Before activating the unit:
- Close the electric panel lid.
- Position the door-block disconnecting switch of the machine on ON,
turning the handle down. (fig.3)
- Press the key ON to start the machine (fig.4);
when the access LED appears the unit is ready for the operation.
22.3. SEASON CHANGEOVER
- For each seasonal change check that the operation conditions return to the limit.
- Check that the absorption current 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%.
22.3.1. Season change of the panel on the machine
To activate season change, just press the key indicated
in (fig. 5). Switch off the unit in stand-by must be activated in remote and local
mode.
For further information refer to the USER MANUAL.
WARNING
The fi rst start-up has to be
carried out with the standard
settings, only at last test vary
the values of the operation
Set Point.
Before starting, power the
unit for at least 12-24 hours
by positioning the protection
thermomagnetic switch and
the door-block disconnecting
switch on ON fi g.1
Make sure that the control
panel is turned off until it al-
lows the oil heater system the
compressor casing.
