WARNING: Installation must be carried out by a qualified engineer.

3.7 Electrical installation
To function safely and maintain the integrity of your electrical system, the unit must be connected to a general
electricity supply in accordance with the following regulations:
Upstream, the general electricity supply must be protected by a 30 mA differential switch.
The heat pump must be connected to a suitable D-curve circuit breaker (see table below) in accordance with
current standards and regulations in the country where the system is installed.
The electricity supply cable must be adapted to match the unit’s rated power and the length of wiring required by
the installation (see table below). The cable must be suitable for outdoor use.
For a three-phase system, it is essential to connect the phases in the correct sequence. If the phases are
inverted, the heat pump’s compressor will not work.
In places open to the public, it is mandatory to install an emergency stop button close to the heat pump.
