6.2. Connection of ushing water
For the machines ordered for connecon to ushing 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 dra ushing water is delivered according to these requirements to prevent con-
taminaon by sucon in drinking water pipes.
This standard EN 1717 denes ve liquid categories that are or could come into contact with drinking
water. Category 5 is the category with the highest protecve 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 protecon against contaminaon
of drinking water pipes.
Connecon of ushing water to the delivered machine may only be carried out by a qualied VA in-
staller and in accordance with current local VA regulaons. DISPERATOR takes no responsibility for,
according to standard EN 1717, a machine that is incorrectly connected to the drinking water line.
The machine’s automac 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 ushing water to the machine, the incoming water pipe (incl.
accessories and protecon devices against sucon, cut-o valves, etc.) must have the same
dimension as the connecon to the machine assembly, ie. DN15. No throling may exist up to
the ushing water connecon on the machine.
6.2.2. Line Strainer DN15 and Solenoid Valve DN15
The delivered line strainer, DN15 must be mounted in the ow direcon 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 ow direcon (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 mounng that is welded into other manufacturers’ table tops / workbenches, and for
freestanding cabinet and table mounng, these components are pre-assembled from the factory
on the assembly for connecon to cold water supply. Connecon 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 connecon for
ushing water on the machine assembly, a hose with protecve steel-covered stocking (with
minimum inner-Ø 9 mm) must be ed. This hose absorbs the compressive push in the pipe
when the ushing water is turned on and absorbs any small vibraons which may occur during
the grinding process of the disposer. This hose is not included in standard delivery but is available
as an opon from Disperator.
