    IMPORTANT FACTS - READ BEFORE COMMENCIN G PUMP INSTALLATION Water Storage Capacity The hot and cold water storage capacity must be sufficient to meet the flow rates required by the pumped equipment and any other water using fittings and appliances, which may be operated simultaneously. Ensure the pump is primed as described in the priming section before starting, damage to the shaft seal will result otherwise.

  • Page 12 Preferred Pump 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. The pump location is also dependent on limitations of the static inlet and outlet heads of the installation.
  • Page 13 Non-Preferred Pump Location If it is necessary to position the pump above the secondary tapping on the hot cylinder it is fed by, the risk of introducing air will be increased. To avoid this risk one of the two following solutions must be adopted: a.
  • Page 14 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 22 mm minimum. Do not connect to the mains.
