7 Installation requirements

7.1 Siting

Locate the VANTAGE in the building in the most conveni-
ent position ensuring that:
– The discharge pipe from the tundish can be installed
with a minimum fall of 1:200 and can be terminated in
a safe and visible position (see section 7.5 Discharge
pipework).
– The base chosen for the unit is level and capable of
supporting the weight of the cylinder when full
(see section 2: Technical Data).
– The installation site is frost-free. If necessary provide
a frost protection thermostat.
– Access is available for user operation of the DHW tem-
perature control on the cylinder.
– Suitable clearances exist to allow installation, checking
and repressurising of the expansion vessel.
– The installation site chosen does not result in excessi-
ve "dead leg" distances, particularly to the point of
most frequent use.
Note:
For larger systems incorporating long pipe runs
a secondary return connection is provided on
the top of the cylinder. A recirculation system
incorporating a suitable non ferrous pump may
be connected into this point.
– A suitable cold mains water supply pipe can be provi-
ded to the VANTAGE direct from the main water stop
valve of the building.
