Electric heater Aqua HL

Electrical installation

WARNING
• The electrical installation must only be performed by an authorised electrician and in
accordance with national statutes and regulations.
• The electrical installation shall be done via an all-pole circuit breaker, as well as a residual
current device indirectly via a contactor controlled from the pump's electrical connection.
This will prevent the heater from starting without the water circulating.
• The heater must be connected electrically according to the electrical diagram below.
Verify against the rating plate on the product.
The electrical installation work is done AFTER the plumbing has been installed. A permanently installed installation cable is
recommended.
If the circulation pump is fitted with a protective motor auxiliary relay, this must be connected to connection blocks P1 and P2;
refer to the schematic diagram for the respective voltage and number of phases. When the motor protector is engaged,
the circuit shall be closed with a floating-voltage change-over contact.
If no external motor protector is present, connection blocks P1 and P2 must be connected together (strapped).
Make sure that the connecting wire cannot come into contact with the hot parts of the element.
When the electrical installation is complete, the cover is place onto the connection box.
