This Essentials shower complies with all the relevant directives for CE marking.
Plumbing
1.
The appliance is designed to operate with a minimum maintained inlet pressure
of 0.8 bar up to a maximum static inlet pressure of 10 bar.
2.
The appliance is normally connected to the cold water mains-fed supply. However,
the water supply can be taken from a cold water storage cistern, provided there is a
minimum maintained inlet head of water of 8 metres (the vertical distance from the
base of the cold water storage cistern to the shower fitting handset). To reduce
pressure losses and fluctuations, the cistern-fed water supply must be independent
from other supply draw-offs, and should avoid long horizontal pipe runs and use
swept bends rather than 90° elbows. The appliance may be installed with a shower
pump to increase the cistern-fed inlet supply pressure. For further advice please
refer to the back cover of this guide for Caradon Plumbing Solutions contact telephone
and fax numbers.
3.
The appliance is suitable for installation within the shower area. It is fitted with a
pressure relief device and must be positioned over a water catchment area with the
controls at a convenient height for the user. 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 appliance.
