Installation and operating instructions
2.2
Function description
Unfiltered water flows into the device
through the rotary flange. The water flows
from the outside to the inside through a
cylindrical sieve insert. Dirt particles remain
on the sieve fabric of the sieve insert. The
adhering residues are visible from outside
through the transparent filter bowl.
SPEEDY-LONGLIFE ¾" - 1¼": The filter
bowl is visible through the viewing slot of
the UV protection screen. The UV protection
screen can be moved downwards to check
the contamination.
Subsequently the filtered water exits the
device again via the rotary flange fitting.
