6.3 Cold Water Connection
The cold water supply: Must be a DEDICATED AIR FREE supply via a tank
connector, and must be positioned at a slightly lower level (25 mm minimum) than
the feed pipe to the hot water cylinder.
Ensure that the pipework size from the cold water tank is 22mm minimum.
Do not connect to the mains.
6.4 Hot Water Connection
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.
Hot water supply: The pump must be supplied with a dedicated feed direct from
the hot water cylinder or storage tank, ensuring an air free connection to the
pump. We recommend the use of either the side entry flange (SE) Part No 27900
or a top entry flange (TE) Part No 27800 see Figure 7.
Expansion pipe: When the method of connection is to be made via the expansion
pipe, the BASE of the cold water storage tank MUST be at least 1 metre above the
connection/take off of the hot water storage cylinder feeding the pump.
