Victorum PrePlumb
Piping
Connecting To The Cylinder
It is recommended to use copper pipes where possible.
If plastic pipes are used, they must be approved for a
temperature of 95°C at a pressure of 10 bar.
If Alupex pipes are used, it is recommended to increase
the pipe size by one diameter as crimp connections
incorporate an insert which dramatically reduces the
inner diameter.
It is also recommended to install a thermostatic mixer on
the hot outlet of the tank to prevent the risk of scalding.
Heat Pump Primary Connections
Connect the primary connections from the Heat Pump
to the unit as shown below.
The primary flow connection is on the bottom of the inline
heater and is a 3/4” internal thread. The primary return
connection is on the return block of the pre-plumbed
manifold and is a 22mm compression connection.
Heating System Pipe Conenctions
Connect the heating zone connections as shown below.
In the Victorum PrePlumb unit the heating zone valves
are pre-installed. The hot water zone valve is also pre-
installed.
All heating zone return pipes should be joined at the
cylinder and return via the common heating return as
shown below.
Heating Expansion Vessel
The PrePlumb unit does not have an expansion vessel
incorporated. The installer must ensure the system is
protected from the effects of expansion by installing a
suitably sized expansion vessel.
Refer to section ‘Sizing, positioning and pre-charge
pressure of the heating system expansion vessel’ for
vessel sizing.
