The HRC
70
Heat Pump is CE-marked. It complies with the
French standard NF C15-100 and the European standards
EN 61000-3-3 et EN 61000-3-11, among others.
It is equipped with soft starters, which limit the start-up
current to 45A for single phase and 60A for three phase.
The power supply cable should be carefully sized according
to the following factors:
- maximum current
- the distance between the HRC
70
Heat Pump and
the power supply source
- overall protection
- the neutral operating system
Take care to strip the cable before pushing
it into the terminals, and make sure that the
copper is in good condition.
A means of disconnection must always be  tted in
compliance with the installation rules.
If the power supply cable is damaged
it must be replaced by a suitably
quali ed professional.
To access the terminals, remove the
panel on the bottom left hand side (2
screws) and open the electrical box (8
screws).
The electrical power supply cable
should  rst be inserted through an
exterior compression gland and then
through a cable grommet on the
electrical box.

The figures given here are indicative. They must be checked and modified if necessary according to conditions of installation and
current rules and standards. If the length of the cable exceeds 15m or if the network could be subject to drops in voltage over 10V, use a
thicker cable.
(*)
The ground cable width must be equal to the width of the largest power supply cable.
See tables:
"Connecting the Pilot to the power supply"
3.5.3 - Connecting the HRC
70
Heat Pump to the power supply
- It is the responsibility of the installer and the client to contact the electricity provider and ensure
that the appliance is compatible with the power grid before connecting the HRC
70
Heat Pump (see
the information form which is an appendix to this document).
- The power grid impedance value must be less than the Heat Pump impedance Z
max
(see § "Connecting the
HRC
70
Heat Pump to the power supply").
- If electrical installation standards are not respected, irreversible damage could be sustained to the HRC
70
Heat Pump, which will not be covered by the manufacturer’s warranty.
