6. The shower is suitable for installation within the shower area. The shower is fitted with
an internal pressure relief valve and must be installed over a water catchment area.
7. Position the shower where the controls area at a convenient height for the user.
Position the showerhead so that the water sprays in line with the bath or across the
opening of a shower cubicle. The showerhead must not spray directly onto the shower
unit during normal use. The installation must not cause the shower hose to be kinked
during normal use.
8. The shower must be fitted to a waterproof, flat and even wall surface. The 3 screws
(No. 8 x 1¼") and wall plugs supplied are suitable for most solid wall installations. Alternative
fixing screws for panel structures are not supplied. Use all 3 fixing points to secure the
shower unit, be sure to use fixings appropriate for the chosen wall structure.
DO NOT fit the shower to the wall and tile up to the case or seal the gap between the
shower and the wall surface with sealant.
9. The shower is intended to be permanently connected to a gravity fed water supply
using the inlet connection supplied as part of the shower unit.
DO NOT use any other type of fitting.
10. Use a minimum of 15 mm diameter supply pipework. For long pipe runs, this should
be increased to 22 mm (see "Pipework" for guidance and calculation table). When
using flexible plastic pipe it is essential that the pipe is kept flat to minimise air build
up in the system.
11. A full bore/non restrictive servicing valve must be fitted in a readily accessible position
adjacent to the shower to facilitate maintenance of the shower.
