7.1.1 Water Supply
With regard to the water supply, the provisions of the DVGW
in accordance with DIN 1988, part 4, (Technical Regulations
for Drink-Water Installations), are to be followed.
a) Cooling Water Inflow (3/2)
The cooling water delivery pipe (hose with a connector on
both sides G3/4) is connected to the cooling water inflow
(3/2) and the on-site G ¾ water valve. The cooling water
inflow is provided with a hinged cover which is to be
removed from the cooling water delivery pipe before it is
connected. The hinged cover should be stored at a secure
place.
In the case of equipment failure, the back-flow of processed
water, (used drinking water), into the drink-water system is to
be prevented by a back-flow prevention device, either as
single safety system at the apparatus supply or via a
collective safety device system for the work area,
(department, practice, etc.).
As single safety system, a back-flow prevention device with
pipe ventilation, which screws directly onto the water valve
G 3/4, may be supplied, (article no. 5 1630 0120), (to be
installed at the wall). Please note, that the water valve must
be situated at least 150 mm above the apparatus supply, (see
chapter 10).
IMPORTANT:
When deinstalling the Water Cooling the cooling water inflow
has to be tightened with the lock again. Otherwise water
leakage is possible.
