Connect the cold water supply to the inlet connection below the solenoid valve

This unit is intended to be permanently connected to the water mains and
should not be connected by a detachable hose-set.
•
It is recommended a service valve is fitted close to the unit to aide future
maintenance.
Connect the vent pipe to the vent connection
(marked VENT). The vent pipe should be as short
as practical (max 400mm), fall continuously and
discharge to a safe and visible place.
A tundish (an inexpensive air break device readily
available from plumber’s merchants) is required
if the vent pipe would be more than 400mm in
length or contain bends.
WARNING
The unit will malfunction if steam cannot easily escape via the vent pipe.
Do not confuse the vent and the inlet pipes – serious damage may result.
Any plastic pipework or fittings connected to the vent pipe must be rated
to 100°C minimum.
The unit should only be used with the tap provided, do not attempt to
change or modify it in any way.
