Cold Water Installations
Before deciding where to locate the unit, check to ensure the static inlet head (Fig. 8)
meets the minimum requirement of 1 metre and does not exceed the maximum
requirement of 8 metres for U1.4 and 10 metres for other models.
The static outlet head (Fig. 8) must also be within the maximum requirement of 8 metres
for U1.4 and 13 metres for other models.
Hot Water Installations
The preferred pump location is at floor level next to the hot water cylinder or a level that
is below the secondary tapping that feeds the pump. This will ensure the pump has access
to an air free water supply which is important for trouble free operation (Fig. 9).
Preferred Pump Location
(shaded area). Pump at
a level below the cylinder
draw off tapping.
