Example for installation
If installing into a vertical line, the coarse
particles, deposited in the grit trap can’t be
flushed out as optimally as when installed
horizontally. Tension-free installation has to be
observed!
Example for installation
The installation of the Backwash Protective
Filter is effectuated up to a water pressure
of 150 psi (1000 kPa), and concerning 2½"
(DN 65) up to 232 psi (1600 kPa) behind the
water meter, and the backflow preventer
before a possibly mounted pressure reducer
(see fig. 3).
In the event of water pressure above
150 psi (1000 kPa), the pressure reduction
valve should be fitted in front of the Back-
wash Protective Filter (see fig. 3). If the
operating pressure is above 150 psi
(1000 kPa), this may result in defects during
operation.
For the backwashing water a wastewater
connection (for example a floor drainage) in
accordance with DIN 1986 must be in place.
If a wastewater connection directly under
the filter is not possible, the rinse water can
be led by means of a line to be mounted on

The installation of a pressure
reduction valve is recommended for
water pressures between 73 psi
(500 kPa) and 150 psi (1000 kPa).
