•
Protect the flange surfaces against
damage to ensure proper sealing.
•
Protect the device from dirt so as not
to impair drinking water hygiene.
•
Store the device in a frost-free place
to prevent damage caused by freez-
ing water and leakage.
Unauthorised conversions and changes
are forbidden for safety reasons. These
can impair the functioning of the device,
leading to leaks and, in the worse case
scenario, to bursting of the device.

Installation and operating instructions
2.2
Function description
Unfiltered water flows into the device
through the built-in rotary flange and the
backflow preventer (only for JUKO-LF
1½" - 2"). A coarse filter prevents large dirt
particles from reaching the fine filter (only
JUKO-LF 1½" - 2"). The water flows from
the outside to the inside through a cylin-
drical 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.
JUKO-LF ¾" - 1¼": The filter bowl is visible
through the viewing slot of the UV protec-
tion screen. The UV protection screen can
be moved downwards to check the contam-
ination.
The filtered water continues to flow into
the pressure reducer. The set downstream
pressure can be read at the downstream
pressure gauge.
Subsequently the filtered water exits the
device again via the rotary flange fitting.
