Mains power

Note
The water heater is supplied without a power cable and isolator.
Use a power cable with wires of a suitable diameter based on the cable length and the
current.
Note
Select and install an overvoltage category III, all–pole isolator with a contact gap of at
least 3 mm. The all–pole isolator must be incorporated in the fixed wiring in accordance
with the wiring rules.
Note
This isolator must be installed in the same room as the appliance, suitably marked and
no more than 1 meter away from the water heater.
Note
The length of the mains earth core that is connected to the electrical connection must be
longer than the core of the mains live (L1, L2 and L3).
Connect the water heater to the mains power supply:
1. Pull the power cable through the cable gland.
2. Connect the live (L1, L2 and L3) and the earth (A) core of the power cable to the
terminals of the terminal block.
3. Connect the power cable to the isolator.
4. Secure the power cable in the cable gland.

Finalization

When all connections are made, close the door of the water heater.
