The pump must be mounted horizontally with outlets vertically upwards to ensure correct
operation of the flow switches.
If the pump is to be installed in the loft, there may not be sufficient head to feed the
pump and damage from freezing is possible. (See Note 3 of Section 2).
To reduce noise that may be caused by vibration we recommend the pump be
mounted on a small concrete paving slab approximately 225 x 225mm (9”x 9”) and
40–50mm (1
1
/
2
” to 2”) thick.
Connect pump and shower system as shown in Fig. 1.
There must be a minimum height between the water level in the cold water storage
cistern and the outlet of the shower handset of 250mm (10”). See Fig. 1.
Negative Head
If the water level of the cold water storage cistern is below the level of the shower outlet, this
is called a negative head system. To enable the pump to operate it must be either an
Automatic Negative Head pump from the Watermill ANH range or alternatively a Negative
Head Kit needs to be used.
There must also be a minimum height between the water level in the cold water storage
tank and the pump inlet of 2 metres. Suggested location for the pump, if space allows, is on
the floor of the airing cupboard. The area must be well ventilated – the pump must not be
covered by boxes, clothes etc, otherwise the motor will overheat.
