6.2. Connection of flushing water
For the machines ordered for connection to flushing water according to the requirements of standard
EN 1717 (in the UK also WRAS), or to be installed in countries where this standard must be complied
with, the machine’s draft flushing water is delivered according to these requirements to prevent con-
tamination by suction in drinking water pipes.
This standard EN 1717 defines five liquid categories that are or could come into contact with drinking
water. Category 5 is the category with the highest protective requirements and which applies in all
kitchens where food is handled, regardless of whether food waste management equipment is there
or not. If stated when ordering, all Disperator’s machine models can be delivered in accordance with
the requirements for category 5, ie. the category with the highest protection against contamination
of drinking water pipes.
Connection of flushing water to the delivered machine may only be carried out by a qualified VA in-
staller and in accordance with current local VA regulations. DISPERATOR takes no responsibility for,
according to standard EN 1717, a machine that is incorrectly connected to the drinking water line.
The machine’s automatic rinsing water control is to be connected to cold rinsing water (hot water is
not needed).
6.2.1. Water pipe DN15
To provide the correct amount of flushing water to the machine, the incoming water pipe (incl.
accessories and protection devices against suction, cut-off valves, etc.) must have the same
dimension as the connection to the machine assembly, ie. DN15. No throttling may exist up to
the flushing water connection on the machine.
6.2.2. Line Strainer DN15 and Solenoid Valve DN15
The delivered line strainer, DN15 must be mounted in the flow direction before the solenoid
valve, DN15 in the incoming cold water pipe to the machine. Also make sure that the line
strainer and solenoid valve are mounted in the correct flow direction (see the arrow on these
components), and that the nut on the line strainer (which is to be opened when cleaning the
line strainer) is directed downwards. Line strainer and solenoid valve have G½” (BSPP), internal
thread.
For funnel mounting that is welded into other manufacturers’ table tops / workbenches, and for
freestanding cabinet and table mounting, these components are pre-assembled from the factory
on the assembly for connection to cold water supply. Connection to these assemblies is R½”
(BSPT), external thread.
6.2.3. Hose with Protective Steel-Covered Stocking for Flushing Water, minimum
inner-Ø 9 mm
Between the incoming water pipe mounted on the wall/bulkhead, and the connection for
flushing water on the machine assembly, a hose with protective steel-covered stocking (with
minimum inner-Ø 9 mm) must be fitted. This hose absorbs the compressive push in the pipe
when the flushing water is turned on and absorbs any small vibrations which may occur during
the grinding process of the disposer. This hose is not included in standard delivery but is available
as an option from Disperator.
