NOTICE
Risk of damage to due pressure surge!
The abrupt fi lling of the station can lead to damage,
e.g. to the sensors or sealing points.
!
Always open and close ball valves slowly.

2
Slowly open the shutoff ball valve for potable water
(cold) (position
on page 11).

Perform a tapping process.
During the tapping process, air remaining in the
potable water circuit is discharged via the draw-
off point.

Electrical connection

After the power supply has been established, the
controller goes through an initialisation phase.
NOTICE
Malfunctions due to electromagnetic fi elds!
Strong electromagnetic fi elds can impair the
function of the controller.
!
Ensure that the product is not exposed to
strong sources of electromagnetic radiation.
If you use a potable water circulation set, observe
the operating instructions for the accessory.
Make sure that the product can be disconnected
from the power supply at any time.

If noises due to trapped air continue to occur in the
potable water circuit, slightly open the fi ll and drain
ball valve for potable water (hot) (position
21 on page 29 and in Fig. 1 on page 11) until
only water escapes.
Position the mains plug so that it is accessible at all
times.
If this is not possible, install a switch that is acces-
sible at all times. In this case, it must be possible to
disconnect the product from the mains at all poles
via an additional device with an isolating distance
of at least 3 mm or with a disconnecting device
(fuse) in accordance with applicable installation
regulations.
