Installation of the 'water stop valve' kit
• Insert the filter (1) into the water stop valve
with the curvature of the sieve facing up-
ward. (Fig. 1)
Improper filter installation will have a

tap.
• Insert the sealing ring (2) into the supply
hose (3). (Fig. 1)
• Connect the supply hose (3) of the dispenser
to the bottom part of the water stop valve.

still be on the screw connection. Screw
on the water stop valve by hand only.
