6.2. Connection of ushing water
For the machines ordered for connecon 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-
taminaon by sucon in drinking water pipes.
This standard EN 1717 denes ve liquid categories that are or could come into contact with drinking
water. Category 5 is the category with the highest protecve 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 protecon against contaminaon
of drinking water pipes.
Connecon of ushing water to the delivered machine may only be carried out by a qualied VA in-
staller and in accordance with current local VA regulaons. DISPERATOR takes no responsibility for,
according to standard EN 1717, a machine that is incorrectly connected to the drinking water line.
The machine’s automac 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 protecon devices against sucon, cut-o valves, etc.) must have the same
dimension as the connecon to the machine assembly, ie. DN15. No throling may exist up to
the ushing water connecon on the machine.
6.2.2. Line Strainer DN15 and Solenoid Valve DN15
The delivered line strainer, DN15 must be mounted in the ow direcon 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 direcon (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 mounng that is welded into other manufacturers’ table tops / workbenches, and for
freestanding cabinet and table mounng, these components are pre-assembled from the factory
on the assembly for connecon to cold water supply. Connecon 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 connecon for
ushing water on the machine assembly, a hose with protecve 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 vibraons which may occur during
the grinding process of the disposer. This hose is not included in standard delivery but is available
as an opon from Disperator.
