4.4.1.
Water supply
The machine should be connected to a suitable cold water supply as follows:-
The connection to the machine water tank is made at the rear of the machine on the top
right hand side corner of the machine. It is a standard connection to a
¾” BSP male
fitting. Flow rate should be 4 litres per minute minimum.
Note:
The inlet flow valve is supplied already fitted with a flow restrictor in place. The
restrictor should be left in place on tank fed installations with heads above 50ft or mains
fed installations with pressures above 1.5 bar (25psi). In all other circumstances the flow
restrictor is not required.
4.4.2.
Drain connection
The drain is connected by inserting a
2” pipe into the blue flexible outlet and fitting &
tightening the clip provided. Please note there is a P trap integrated into the machine so
an external one is not required.
Points to Watch
Ensure that the supply line to the unit is at no point less than 15mm - larger
if available head is low.
Ensure that the water supply cannot be starved by any other fittings.
Fit an easily accessible, full way isolating valve close to the unit.
For installations with dirty water supplies it is recommended that an in-line
filter is fitted.
Ensure that the route taken to soil drain is the shortest, with minimum
number of bends.
If necessary
, use long radius or ‘swept’ bends - never short or 90’ elbows.
The waste must be run separately to the soil stack or drain.
Ensure that there is a fall of a minimum of 1 in 25 or a sufficient fall to
maintain a self-cleansing velocity.
Provide easy access for roding.
Ensure a clean run inside the pipework - leave no burrs or reducing
shoulders.
With plastic pipework, ensure that there is no reduction in the bore size and
that there is adequate support for horizontal runs to prevent sagging.
Remember, ceiling voids can get very warm.
Avoid running the drain line near or across hot water pipes.
Anti-syphon precautions should be in line with general practice.
