Cold water connection:
2.27
The cold water supply: The supply must be air free and have a dedicated
connection to the tank which should be via a tank connector, positioned at a
slightly lower level (25 mm minimum) than the feed pipe to the hot water cylinder.
Do not connect to the mains.
2.28 Location: The pump must, for optimum performance, be sited as close as
possible to and never more than 4 metres from the HOT WATER cylinder. The
pump should always be sited BELOW the HOT WATER take-off from the cylinder.
Hot water connection:
(Applicable to U1.5, U2.0, U3.0 and U4.0 bar Twins)
2.29
Hot water cylinder or storage tank: When a hot water cylinder or storage tank
is used, ensure the pipework size from the cold water storage to the hot water
storage is of adequate size and a minimum of 22 mm. The U4.5 bar Twin should
have pipework of a minimum of 28 mm.
2.30 Hot water supply: The pump must be supplied with a dedicated feed direct from
the hot water cylinder or storage tank. We recommend the use of the Stuart top
flange Part No 27800 (for all models except the U4.5 bar Twin).
2.31 The supply must be air free and connection to the cylinder can be made by one of
the methods shown in Fig. 5 (S4.5 bar Twin should only use ‘a’ or ‘d’).
2.32 Expansion pipe: When the method of connection is to be made via the
expansion pipe, the cold water storage cistern should be at least 1 metre above
the top of the hot water cylinder.
