*Maximum cable length between heat pump and head of line protection (C curve current protection)
It is recommended to use wire terminal for better electrical contact between wire and power supply terminal.
These data are only indicative, you must ask an electrician to determine the exact data for your pool installation.
Power supply must be equipped with grounding and 30 mA differential protection.
• Use the cable-gland and the pass-throught provided inside the HP for the passage of the cable.
• As this heat pump is installed outdoors, it is mandatory to pass the cable through a protective sheath for this purpose. The power supply of the HP must be
fitted with a protection device in accordance with the legislation in force.
• The electric cables must be buried at a depth of 50 cm (85 cm under a road or a path) in an electrical sheath (red corrugated). When a cable buried in a
sheath crosses another cable or a pipe (gas, water, etc.) the distance between them must be greater than 20 cm.
Automation
You have a very low voltage terminal block to which you can connect your home automation. This
is an ON / OFF dry contact. Remove the existing bridge. When your home automation opens this
contact, the machine stops and displays the message: No flow.
