Replacing batteries

• Open the battery compartment (D) by rotating

the cap (C) and electronic unit (E) away from

each other and removing the cover (see ﬁgures

3+4).

• Remove the empty batteries.

• Insert two new 1.5 V LR03/micro/AAA batteries

into the battery compartment, making sure that

you insert them the right way round (see ﬁgure 6).

• Please pay attention to the ﬂashing signals of the

device LED while inserting the batteries (s. „7.4

Error codes and ﬂashing sequences“ on page

34).

• Replace the cap on the electronic unit and tigh-

ten.

Once the batteries have been inserted, the water sensor

will perform a self-test/restart (approx. 2 seconds). Af-

terwards, initialisation is carried out. The LED test display

will indicate that initialisation is complete by lighting up

orange and green.

Caution! There is a risk of explosion if the battery

is not replaced correctly. Replace only with the

same or equivalent type. Never recharge standard

batteries. Do not throw the batteries into a ﬁre.

Do not expose batteries to excessive heat. Do not

short-circuit batteries. Doing so will present a risk

of explosion.
