unless there is a guaranteed 114 litre cold supply
to the cylinder as the shower can deliver up to
14 litres per minute. It is advisable to check that
the infill rate from the float operated valve meets
the output requirements..
It is recommended that there is a minimum of
approximately 114 litres (25 gallons) of hot
water storage per appliance.
The shower MUST NOT be connected to
the mains cold water supply.
DO NOT use jointing compounds.

Shower control MUST be fed from a cold
water storage cistern and hot water cylinder
that provides nominally equal pressures.
5
The unit must be mounted onto the finished
wall surface (on top of tiles).
DO NOT tile up to the unit after fixing to
the wall.
6
If installing with rear inlet supplies, it is
recommended the supply pipework is sealed
to the wall so as to prevent water from
leaking back into the wall.
7
In solid wall installations, the supply
pipework should be housed within ducting
in order to allow some free lateral
movement when making connections and
to ensure compliance with requirements of
accessibility of pipes and pipe fittings.
