JUDO PROFIMAT-PLUS
Intended use
2.1
Water pressure
The water pressure should be between
1.5 bar and 10 bar.
The water pressure must not drop below
1.5 bar as otherwise the backwashing can
be impaired! If the filter is not backwashed
regularly a pressure loss can result and this
can impair the filter function.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
In the event of
water pressure above
10 bar
, the pressure reduction valve should
be fitted
in front
of the automatic backwash
protective filter (see fig. 2). If the operating
pressure is above 10 bar, this may result in
defects during operation.
2.2
Notes on special dangers
2.2.1 Electrical equipment /
installations
Electrical devices / equipment that are not
splash-water proof and are situated in the
direct vicinity of the filter may be damaged
by water leaking from the filter caused as a
result of the device not being operated in
accordance with the manufacturer’s specifi-
cations. In addition this may also result short
circuits if these electrical devices / equip-
ment being connected to the electrical
power supply. In the event of such cases
persons are at risk and may sustain elec-
trical shocks. Therefore any electrical
devices / equipment situated in the direct
vicinity should be splash-water proof,
respectively comply with the statutory
requirements for wet areas (IP44).
2.2.2 Potential-free input
2.2.3 Potential-free output
Switched voltage...........maximum 24 V
Current ............................ maximum 1 A
(see chapter “Potential-free message”)

Pressure reducer upstream of the unit
The installation of a pressure
reduction valve is recommended
for
water pressures between
5 bar and 10 bar
.

There must not be any electrical
cables and devices underneath or
in the immediate vicinity of the filter!
Only isolated switching contacts may
be connected to the potential-free
input.
No external voltage may be
impressed on the potential-free input!
Applicable safety requirements and
electrical regulations must be
observed without exception!
Only extra-low voltage may be
used for the remote transmission
of the fault message by means of
the isolated output!
