13 - COMMISSIONING

13.1 - Checks prior to commissioning

■ It is advisable to make a complete sketch of the installation
including the location of the unit and all the components used.
This will be very helpful for maintenance and repairs to the
installation.
■ The following must be verifi ed:
- That the electrical power supply remains constant and that it
corresponds to that featured on the unit data plate.
- That the electric installation has been carried out according
to the electric wiring diagram provided with the unit (consult
the chapter on "Electrical connection").
- The correct connection of the sensors supplied with the unit
(consult the chapter on "Electrical connection").
- That they are no cables close to heat sources.
■ Once the above verifi cations have been carried out, the control
circuit is supplied with voltage by the automatic control switch.
Attention: the compressor crankcase heater must be put under
voltage for 24 hours before starting the compressor.

Important: As a safety feature to ensure heating of the
crankcase heater, if there is a power cut lasting over 2 hours,
the compressors will be locked. The unit must be powered for
8 hours to unlock them. The graphic terminal will displays the
time remaining until they can be unlocked.
■ All the units are equipped with
scroll type compressors and a
phase control relay. Verify that they
rotate in the correct sense and, if
not, reverse the power wires.
Optionally, these compressors can be fi tted with a semiconductor
compressor softstarter which limits the starting current using
an auto adaptive algorithm.
■ Check the unit operation and verify the safety devices.
