5.1

Electrical panel side

The line supplying the heat pump must be configured and fitted with one or more devices for:
• proper earthing of the machine
• protection of people by means of a 30 mA residual current device (interrupter or circuit breaker) dedicated
to the pool electric panel or specific to the heat pump line (unless the house is already equipped with one)
• protection of the machine against "overloads" and short-circuits by means of a thermal magnetic circuit-
breaker
To avoid the untimely tripping of the circuit breakers on starting up the machine, use D curve circuit breakers.

Heat pump side

The machine is wired in by means of the white connection box beside the information plate.
• Remove the protective casing from the heat exchanger.
• Withdraw the 4 plastic screws from the lid of the connection box to release and remove the lid.
• Feed the power cable into the box, pushing them up through the cable glands located in the bottom.
• Strip the 1 cm of each wire, and connect these to the domino, taking care to respect the live, neutral and
earth phases.
• Tighten the cable gland nuts to immobilise the cable and ensure that the seal around the cable is leak tight.
• Replace the lid and screws, then replace the heat exchanger casing.
