NOTICE
Risk of damage due to pressure surge!
Sudden fi lling of the station can cause dam-
age, for instance to the sensors or sealing
points.
f Always open and close ball valves slowly.
slowly (see position (7) in Illust. 21 and in Illust. 1 on
page 10).
slowly (see position (9) in Illust. 21 and in Illust. 1 on
page 10).
During draw off operation, any remaining air
in the potable water circuit is drained via the
draw-off point.
f If noises persist within the potable water cir-
cuit as a result of airlocks, open the fi ll and
drain ball valve for potable hot water slightly
until only water escapes (see position (17) in
Illust. 21 and in Illust. 1 on page 10) .
Electrical connection
Once the power supply has been established,
the controller goes through an initialisation
phase.
NOTICE
Malfunctions caused by electromagnetic
fi elds
Strong electromagnetic fi elds can affect the
controller function.
f Ensure that the product is not exposed
to any sources of strong electromagnetic
radiation.
Refer to the accessory operating instructions
when using a potable water circulation set.
It must be possible to disconnect the product
from the mains at any time.
f Ensure the power plug is connected in a
way that means it is accessible at all times.
f If this is not possible, install a switch that
can be accessed at any time. In this case,
the product must be capable of being
disconnected entirely from the mains via an
additional device with an isolating distance
of least 3 mm and/or with a disconnecting
