CAUTION
Danger of calcification.
Impairment of valve function.
¾
Have a plumber inspect the valve annually.
¾
Remove calcifications by citric acid or acetic acid solutions.
¾
Afterwards test the function and the tightness of the mounted unit
Check: Quickly open the water tap while there is no chamber connected – the valve has to cut off the
water flux without any delay.
4.3.4 Safety kit: Hose burst protection device with reflux protection device (available via
BINDER Individual)
For protection of the drinking water system, acc. to DIN 1988 part 4, and against flooding caused by burst
water hoses, a safety kit with reflux protection device is available.
Protection principles:
Whenever a strong water flow of about 18 l / min. occurs, e.g. caused by a burst water hose, a valve
automatically cuts off the water supply, what can be heard as a clicking noise. The water supply now
remains interrupted until its manual release.
An eventual endangering of the drinking water system depends on the risk potential of the charging mate-
rial. Under unfavorable conditions (e.g. decreasing pressure inside the tap water system), drained off
charging material could be sucked out of the chamber via the steam generator into the tap water system
and therefore contaminate the drinking water. According to standard DIN 1988, part 4, the safety kit with
reflux protection device provides protection in case of short-term utilization of substances with low risk
potential. When using substances bearing a higher risk potential, install a pipe disconnector in order to
guarantee absolute protection. It is the user’s responsibility to prevent, according to national standards,
any reflux of contaminated water into the drinking water system.
Assembly:
The regularly delivered original parts – hose burst protection device, hose nozzle with screwing – are not
needed.
Screw the pre-mounted assembly of hose burst protection device and reflux protection device onto a
water tap with a G¾ inch right turning thread connection. The connection is self-sealing. Establish the
connection between the safety kit and the chamber with a part of the supplied hose. Protect both ends of
the hose by the supplied hose clamps.
We recommend connecting the hose as the last step in order to avoid twisting it while screwing on the
safety kit.
Open the water tap slowly in order to avoid
actuating the hose burst protection device.
