10 Check the marker arrows on the pump
to ensure correct direction of water flow.
Either end of the pump is suitable for hot
or cold water.
11 Check the static inlet and outlet heads
of water above the pump to ensure
maximum limits are not exceeded.
12 The hot supply pipework to the pump
should be a maximum of 5 metres in
22mm pipe (hot and cold supplies should
be no more than 2 metres in 15mm pipe).
Exclusive hot and cold supplies to the
pump with the hot from a Salamander
approved cylinder flange. Exceptions are:
• hot supply – from the vent angled at
45º, vertically down the hot connection
at the vent, at least 1.5 metres below
the base of the cold water storage tank
(Figure 5).
• alternatively, the hot and cold supplies to
the pump can be teed off other 22/28mm
supplies (Figure 6) provided that:
• the tee off to the pump is first call.
• the cold supply to the pump is
not shared with the cold feed to
the cylinder.
13 The best hot connection from the
cylinder (Figure 3) is either with:
• a ¾ inch no stop Essex flange, or
• a Salamander S flange or other
approved top entry flange.
14 Never fit to top entry flange if the pump
is fitted above the cylinder.
15 Check that water storage capacity
meets required flow rates, particularly
at peak demand (i.e. appliances in
simultaneous use).
16 All up and over pipework must be
vented at the highest point on the outlet
of the pump.
17 Ensure pipe runs minimise airlocks.
18 In positive head systems, allow for
increased resistance of long pipe runs
with multiple bends. The natural flow
from the shower head or other outlets
must be at least 1 litre in 30 seconds or
2 litres in 30 seconds mixed.
