8.6 Working principle
8.6.1
Water inlet valve
The main water inlet valve is a 24vdc double check valve which
controls when water can enter the machine preventing leaks prevents
water syphoning and contaminated water in the machine returning to
the main water supply.
An additional double check valve is fitted to the water hose doubling
the safety of leaks and contamination.
8.6.1
Water pressure regulator
This is used to set the incoming water pressure so that
wherever the machine is sited it will use the same drink
configuration settings. It may between sites be required to
adjust the water pressure regulator especially where low
pressure / portable water supplies are used.
8.6.2
Water stop valve
An internal water stop valve allows you to manually turn off
and isolate the water supply. This will help to remove water
and pressure from the system before changing the water
filters and UV lamp.
Turn off the water stop valve by rotating 90 degrees and press
the water flush button to run the last of any water and
pressure in the system. After changing the filters open the
water stop valve and press the water flush button to prime the
water system.
8.6.1
Water filter
The water filter is used to remove sediment and/or
contaminants down to 5 microns within the water system
depending on the type of filter fitted. The water filters must be
installed in the correct position with the sediment filter on the
left.
