Connection of the fuel supply
Refer to the instructions supplied with the burner.
In order for the burner to operate correctly, a filter
(60 μm) must be installed on the fuel supply pipe.
"
Recommendation: The use of a deaerator air
filter is recommended.
Pass the fuel hoses in the passage (either on the right
or left) at the rear of the appliance.
2 .11 Electrical connections
Before carrying out any work, ensure that the general
electrical power supply is switched off.
2 .11 .1 Characteristics of the electrical power supply

Warning!
The contract taken out with the energy supplier must
be sufficient to cover the power of the heat pump as
well as the sum of the power requirements of all of the
appliances likely to be operated at the same time. If
the power supply is insufficient, check with your energy
supplier the value of the power supply defined in your
contract
Never use electrical sockets for the power supply.
The PAC must be powered by special lines protected
from the electrical panel by bipolar circuit breakers
dedicated to the PAC, surve D for the outdoor unit
The electrical installation must be equipped with a
differential protection of 30 mA
This appliance is designed to operate at a nominal
voltage of 230V, +/- 10%, 50 Hz for the single phase
model and at a nominal voltage of 400V, +/- 10%, 50 Hz
for the 3 phase model.
2 .11 .2 General remarks on the electrical connec-
tions
It is essential that the phase-neutral polarity is respected
for the electrical connection
Clamp the cables with stuffing glands to avoid any
accidental disconnection of the conductive wires.
