4.1.1
Safety kit for connection CONDITIONER™ – water main
A safety kit against flooding caused by burst water hoses is enclosed to the sample conditioning cabinet.
It consists of:
•
Hose burst protection device
•
Hose nozzle with screwing
•
4 hose clamps
•
6m water hose, divisible for feed hose and the drain
4.1.2
Protection principle of hose burst protection
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.
4.1.3 Assembly
Screw the hose burst 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 the hose while screwing on the safety kit.
Open the water tap slowly in order to avoid actuating the hose burst
protection device.
4.1.4
Release of the reflux protection device
In case the burst protection device interrupted the water supply, find
first the reason and remove it as far 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.
4.1.5
Maintenance of the assembly of the hose burst protection device
Calcification can impair valve function. We recommend an annual inspection by a skilled plumper. The
plumper should demount the safety kit to check the valve by hand for function and calcification or
blockage.
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.
