3 | Installation of accessories for draining the flushing water
Note:
For the installation examples shown below, the optional closing
plug and flushing fitting cases as well as the flushing water calming tank
are required (see chapter C, accessories)
Warning!
The flushing tube to the drain must be secured during
flushing as the water flows out in a pressurised and pulsating manner.
For hygiene reasons the ends of tubes must not be pushed into drain
pipes and drains or connected to these. To prevent back suction, proper
separation of the drinking water installation from the drain must be
ensured via a free outlet. As per DVGW work sheet W 557 when
flushing with a mixture of air and water, the withdrawal points must be
fitted with the relevant equipment in order to separate the air from the
flushing water. This serves to protect individuals at the withdrawal points
against aerosols.
These requirements are satisfied through use of the flushing water
calming tank (see fig. 10 and 11), order no. 151 020.
If Grünbeck closing caps have already been fitted on the withdrawal
points, e.g., for checking the pressure of new installations, the cap can
be screwed off and the flushing fitting can be directly connected.
If standard closing plugs, or in the case of existing installations other
fittings
(e.g., angle valves, …), are attached, these are to be replaced with the
Grünbeck closing plugs. The flushing fitting is fitted to the Grünbeck
closing plug and the flushing tube is guided to the drain.
