Before performing work on the device
that goes beyond pure operational use,
the device must be depressurised! If
this is ignored, the result may be uncon-
trolled escape of water resulting in water
damage to the building/home.
If the device is removed due to an inter-
ruption of operation:
•
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 rotary flange fitting . 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.
SPEEDYMAT-LF 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.
