■ 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.
