Installation, Use and Maintenance
CAUTION:
All of the installation operations must be carried out when the heat pump is
stopped, and after disconnecting the electrical power supply.
These operations must only be carried out by QUALIFIED PERSONNEL.
Remove the cover without removing the cable duct support plate.
When the work is complete, refit all of the covers removed with their screws and
seals (if present).

WARNING:
Electrical connections must only be carried out by QUALIFIED PERSONNEL, in
compliance with the legislation in force.
Ensure that an adequate earth connection is installed, as inadequate earthing
can cause electrical shocks. The manufacturer cannot be held responsible for
damage caused by ineffective or absence of earthing.
The ratings and dimensions of the power cables, electrical protections and line fuses must
comply with the indications of the unit’s wiring diagram and the electrical data of the technical
specifications table (
see paragraph 2.4.1)).
Use a dedicated power line, do not power the appliance via a line to which other users are
connected. Securely fasten the power cables and make sure they do not come into contact with
sharp metallic corners, which could damage them. Use double-insulated cables with copper
wires.
The earth connection should be made first during the connection phase and vice versa, it should
be removed last when the unit is disconnected. If the power cable comes loose, make sure that
the active conductors are powered before the earth wire.
A proximity switch with adequate breaking capacity must be installed on the supply line, with
contact separation for all poles.
A dedicated C-curve circuit breaker must be installed from the line start in the electrical panel.
This circuit breaker must be rated higher than the maximum current allowed by the outdoor unit,
and a breaking capacity greater than the maximum cut-out current from the upstream power
supply (main low voltage distribution panel or other).
An earth fault circuit breaker compatible with the inverters must be added. For this use, we
recommend fitting a type B differential circuit breaker added must be, as fitting a different circuit
breaker can lead to unwanted tripping.
The following table shows the recommended cable sections for a maximum length of 30 m. In all
cases, depending on the type of installation, the physical location and the length of the cables
(under or over 30 m), the electrical system installer must make the appropriate choice.

The units comply with electromagnetic compatibility specifications, but the electrical installation
designer must make the appropriate assessments to ensure there is no interference.
