4.6 Safety kit: Hose burst protection device with reflux protection device for
the chamber’s freshwater connection (available via BINDER INDIVIDUAL
customized solutions)
A safety kit with a reflux protection device is available for protection of the drinking water system and
against flooding caused by burst water hoses.
Protection principles:
Whenever a strong water flow of approx. 18 l / min. occurs, e.g. caused by a burst water hose, a valve
automatically cuts off the water supply, which can be heard as a clicking noise. The water supply now
remains 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. The safety kit with a reflux protection device provides secu-
rity in case of short-term utilization of substances with low risk potential. When using substances bearing
a higher risk potential, install a pipe disconnector to assure absolute protection. It is the user’s responsi-
bility to prevent (according to national standards) any reflux of contaminated 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.

Release of the reflux protection device:
In case the hose burst protection device interrupts the water supply, first find the reason and remove it as
necessary. Close the water tap. Release the valve by a half left-turn of the upper knurled part. You can
hear the release of the valve as a clicking noise. Tighten the burst protection device against the water tap
by a right turn. Open the water tap slowly afterwards.
Maintenance of the assembly of hose burst protection and reflux protection devices:
Calcification can impair the function of both valves. We recommend an annual inspection by a skilled
plumber. The plumber should remove the safety kit with the reflux protection device to check both valves
by hand for proper function and calcification or blockage.
