CAUTION
Danger of calcification.
Impairment of valve function.
Have a plumber inspect the valve annually.
Remove calcifications by citric acid or acetic acid solutions.
Continue by testing the function and tightness of the mounted unit
Check: Quickly open the water tap while there is no chamber connected – the valve should 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 customized solutions)
A safety kit with a reflux protection device is available for protection of the drinking water system, acc. to
DIN 1988 part 4, and against flooding caused by burst water hoses.
Protection principles:
Whenever a strong water flow of about 18 l / min. occurs, e.g. caused by a burst water hose, a valve au-
tomatically cuts off the water supply, which can be heard as a clicking noise. The water supply now re-
mains shut until it is manually released.
A possible endangering of the drinking water system depends on the risk potential of the charging materi-
al. 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 a
reflux protection device provides security in case of short-term utilization of substances with low risk po-
tential. When using substances bearing a higher risk potential, install a pipe disconnector to assure abso-
lute protection. It is the user’s responsibility to prevent (according to national standards) any reflux of con-
taminated water from getting into the drinking water system.
Assembly:
The standard supplied parts – hose burst protection device, hose nozzle with screwing – are not needed.
Screw the pre-mounted assembly of the hose burst protection and reflux protection devices onto a water
tap with a G¾ inch right turning thread connection. The connection is self-sealing. Establish the connec-
tion between the safety kit and the chamber with a part of the supplied hose. Protect both ends of the
hose with 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.
