Once the hydraulic and electrical connections have been made:
1
Open a hot water tap.
2
Open the cold water tap to vent any air in the installation, ensuring
that valve

on the drain opening is properly closed.
3
The water heater starts to fill up and any air exits via the hot water
taps.

When the water overflows through the hot water tap, the tank is full.
5
Close all of the taps and check the pipes to make sure there are no
leaks.
Caution
If the water inlet pressure is lower than 0.15 MPa (1.5 bar), a
pump must be fitted to the water inlet. To guarantee the safe
use of the tank at a water inlet pressure of more than 0.65 MPa
(6.5 bar), fit a pressure reducer to the water inlet pipe.
