Balanced Cold Outlet
The Balanced Cold outlet connection is
incorporated into the inlet control group. The
connection is designed to supply all cold
outlets within the dwelling, and it ensures
that all cold and hot water pressures and
flows are balanced. This is critical for mixing
showers and taps to provide accurate mixing
of the supplies, otherwise mixing can be
difficult to achieve. The connection is a 22mm
compression connection.
Potable Expansion Vessel
The expansion vessel receives the increased
water volume when expansion takes place as
the system heats up and it maintains a positive
pressure in the system. The expansion vessel
contains a flexible diaphragm, which is initially
charged on one side with nitrogen, but can
be topped up with air when required. Select
a suitable position for the expansion vessel.
Mount it to the wall using the bracket provided
(0-24L only) and hard fix into pipework and
insulate. Ensure that the top of the vessel is
accessible for service and/or maintenance. The
pipe connecting the expansion vessel to the
system should have a diameter of not less than
15mm and must not contain any restrictions.
Hot Water Outlet
Run the first part of the hot water distribution pipework in 22mm. This can be reduced to 15mm
and 10mm as appropriate for the type of tap etc. Your aim should be to reduce the volume of the
hot draw-off pipework to a practical minimum so that the time taken for the hot water is as quick
as possible. Do not use monobloc mixer tap or showers if the balanced cold connection is not
provided. Outlets of this type can back pressurise the unit and result in discharge.
