valid regulations!
4.6
Maintenance, repair,
spare parts
WARNING
The device may only be repaired
by qualified technical personnel.
Only use original spare parts for
repairs.
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 egress of water result-
ing in water damage to the build-
ing/home.
4.6.1 Checking the backflow pre-
venter
(only JUKOMAT-LF-AT 1½" - 2")
WARNING
A defective backflow preventer
must be replaced immediately.
The backflow preventer may only
be replaced by trained technical
personnel.
The testing screw at the inlet connection
of the built-in rotary flange is used to
check the function of the backflow pre-
venter.
1.
Close the stopcock or shut-off valve
upstream of the device.
2.
Unscrew the testing screw (see chapter
2.2).
After a few seconds, no water
may escape from the bore hole.
3.
Screw the testing screw back in.
4.
Open the stopcock or shut-off valve
upstream of the domestic water station
again.
4.7
Integration in building control
systems
The device can be integrated into a build-
ing control system (e.g. EIB / KNX, LCN or
LON) via the floating signal relay.
The potential-free relay is connected to a
binary bus coupler.
In this way, fault messages can be for-
warded to the building control system.
