1.1
the elite St is designed to operate with water supply pressures from 0.8 kPa
(0.008 bar / 80 millimetres head) to 100 kPa (1 bar / 10 metres head) (i.e. the
vertical distance from the base of the cold cistern to the top of the elite St).
however, the minimum head required will increase with pipe length and the
guide given in paragraph 1.17 should be used to make sure that adequate head
is available for any given installation.

1.2 The Elite ST is suitable for installation within the shower area and is fitted with
a pressure relief valve. It must be positioned over a water catchment area with
the controls at a convenient height. The shower fitting should be positioned so
that it discharges down the centre line of the bath, or across the opening of a
shower cubicle, and must be directed away from the shower unit.
1.3 Use a minimum of 15 mm diameter supply pipework. It should be noted, however,
that on long pipe runs this should be increased to 22 mm (refer to para 1.17 for
guidance). When using flexible plastic pipe it is essential that the pipe is kept
flat and not looped up at any point as this may lead to air build up which may
impair performance of the shower.
