Electrical installation
In every case the established national regulations should
be applied.
Each heat pump is delivered with a control box, to which the
power supply will be connected across a fused main discon-
nect switch or automatic circuit breaker.
The electric heater, if available, should be installed with
power supply line and switches independent from those of
the heat pump.
Start-up procedure
a) Connect the power supply cable and earth to the
corresponding boards on the controls box.
b) Give power to the auxiliary control line at 220/240.1.50.
c) Connect the room thermostat line to 24 V on the boards
provided in the heat pump.
d) Before start-up connect the main switch or automatic
circuit breaker to supply power to the electric oil heater in
the compressor crankcase.
Compressor should not be started before a minimum
of 8 hours have passed.
This is necessary to evaporate any liquid refrigerant that
could have mixed with the compressor oil.
Loose cables can cause overheating of the connectors or an
inadequate operation of the unit. Fire risk could also exist.
Fot this reason, make sure that all cables are properly connected.
Do not supply power to the unit and do not start up operations until the
tubing and electrical connections with the outdoor unit have been
completed.
Make sure that the electrical supply is correctly connected to the units,
as shown in the electrical diagrams.

Important: The size of the circuit breaker and the cross-section of the supply and control lines are only as a guide and should be corrected in
accordance with the conditons at the jobsite, distance between units, and current legislation.
