Victorum Compact
Hot and Cold Pipework
The Inlet control group is pre-installed in the bottom section. The mains/boosted cold supply, balanced
cold outlet and the cylinder feed are pre-piped so the installer only has to pipe up-to the unit. The Inlet
control group pressure relief valve is also pre-installed and pre-piped alongside the T&P valve outlet
to the tundish.
The connection for the potable expansion vessel is also pre-installed. The potable vessel is not
included in the unit and it is the installers responsibility to mount and connect the potable vessel to
the pipe provided.
Connect the mains/boosted cold supply inlet and the balanced cold supply outlet from the unit to the
connections shown below.
Water Supply
The performance of any unvented system is only
as good as the mains water supply available. To
this effect the maximum possible water demand
should be assessed, with the knowledge that
the mains supplies both hot and cold services
simultaneously. The hot water storage tank/
water heater itself operates at a pressure of 3bar,
controlled by the inlet control set, and is capable of
delivering over 50 litres per minute. The high quality
inlet control set has been designed to make the most
of the low rates available.
The water supply should be checked to ensure it
can meet these requirements. If necessary, consult
the local water authority regarding the likely
pressure and flow rate availability.
Consideration should be given to upgrading
existing 1⁄2” (15mm) cold mains pipework to
a larger size if the recommended minimum
pressure / flow rate is not being achieved. Joule™
recommend that primary pipework used has a
minimum diameter of 22mm to ensure low pressure
loss.
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. The aim should be to reduce the volume of the hot draw-
off pipework to a practical minumum so that the time taken for the hot water is as quick as possible.
Do not use monobloc mixer taps or showers if the balanced cold connection is not provided. Outlets of
this type can back pressurise the until and result in discharge from the T&P valve.
