Intended use
2.1
Water pressure
The water pressure has to be between 1 bar
(14.5 psi) and 3,45 bar (50 psi).
The water pressure must not fall below 1 bar
(14.5 psi) as otherwise the operation can be
impaired! If the filter is not maintained regu-
larly an elevated pressure loss can come
about and this can impair the filter function.
ATTENTION
(see chapter “Safety indications and
dangers due to non-compliance”)
At a
water pressure higher than 3,45 bar
(50 psi)
, a pressure reducer has to be fitted
before
the under-sink water filter (see fig. 2).
In modern sanitary installations (in particular
where single lever mixers are used), despite
normal system pressure conditions, peak
pressures of up to over 30 bar (435 psi) fre-
quently occur. This can cause damages.
The optimum operating pressure for the un-
der-sink water filter is between 2 bar (29 psi)
and 3,45 bar (50 psi). In this case the under-
sink water filter works most economically.

Notes on special dangers
2.2.1 Electrical equipment /
installations
Electrical devices / equipment that are not
splash-water proof and are situated in the di-
rect vicinity of the under-sink water filter may
be damaged by water escaping from the un-
der-sink water filter caused as a result of the
device being operated improperly. In addi-
tion short circuits may come about if these
electrical devices / equipment are / is con-
nected to the electrical power supply. In the
event of such cases, there is the danger of
electric shock for persons. Therefore all the
electrical devices / equipment situated in the
direct vicinity should be splash-water proof,
respectively comply with the statutory re-
quirements for wet areas (NEMA type 12 /
IP44).

There must not be any electrical
cables and devices underneath or
in the immediate vicinity of the un-
