Installation
See Fig. 2 + 3
Install the crew connection in flow direction into the
horizontal or vertical cold water pipe. (Take note of
the flow direction arrow).
Connect the filter to the connection using the 4 bolts
and the seal.
Operation
HWS only, see Fig. 1
The pressure reducer is set to 4 bar back pressure
ex works. To change the back pressure, loosen the
locking screw (6) and turn rotary button (7).
The back pressure can be changed by turning the
adjusting button (range 1.5 - 6 bar).
Turn the button clockwise to increase the back
pressure.
A
Turn the button anticlockwise to reduce the back
pressure.
The back pressure setting displayed (5) is an ap-
proximate value. The manometer (3) displays the
exact pressure. A draw-off faucet downstream of the
pressure reducer must be opened and closed briefly
several times while setting the value. The back
pressure drops temporarily when water is drained.
The back pressure may not exceed 80% of the pick-
up pressure of the hot water safety valve.
