SITE REQUIREMENTS
Water
The installation must be in accordance with Local
Water Company Regulations/Byelaws and BS6700.
For correct operation of this shower unit, both hot
and cold water supplies to the appliance must be
gravity fed, at nominally equal pressures, from a
cold water storage cistern and a hot water storage
cylinder.
The water circuit should be installed so that the
flow is not significantly affected by other taps and
appliances being operated elsewhere on the
premises.
Fig.2
shows a recommended installation where
the hot water supply for the shower is made via a
tee connection on the underside of the rising
horizontal section of pipework from the cylinder.
Alternatively, the connection can be taken from
the hot supply pipe to other outlets as long as it is
the first draw-off below the ventilation pipe tee.
Fig.3
illustrates all the incorrect connections that
must be avoided.
All pipework to the shower unit must be routed
where it remains below the level of water in the
cistern. In the case of horizontal sections of
pipework in lofts, it may be necessary to fit
automatic air vents at high points on the supplies
to remove the possibility of air locks.
For the operation of the shower only, it is
recommended that the cold water storage cistern
is capable of holding at least 114 litres (25
gallons). Where other hot and cold outlets are
likely to be in use simultaneously, the storage
capacity should be increased to 228 litres (50
gallons) in accordance with BS6700.
Do ensure compliance with all the local Water
Company Regulations/Byelaws.
