Installation
Warning! This product does not allow for reversed inlets and will deliver
unstable temperatures if fitted incorrectly.
General
1.
Installation of the shower must be carried out in accordance with these
instructions by qualified, competent personnel.
2.
The plumbing installation must comply with all national or local water regulations
and all relevant building regulations, or any particular regulation or practice
specified by the local water supply company.
3.
Make sure all pressures and temperatures comply with the requirements of the
shower. See 'Specifications'. For Type 2 Valves, refer to supply conditions
given in the TMV2 Requirements Manual (this is available to view or
download from our website www.radacontrols.com).
4.
Full bore/non restrictive servicing valves must be fitted in a readily accessible
position adjacent to the shower to facilitate maintenance of the shower.
DO NOT use a valve with a loose washer plate (jumper) as this can lead to a
build up of static pressure.
5.
DO NOT apply excessive force to plumbing connections; always provide
mechanical support when making plumbing connections. Any soldered joints
should be made before connecting the shower.
6.
Pipework dead-legs should be kept to a minimum.
7.
DO NOT install the shower unit in a position where access for maintenance is
restricted.
8.
The shower must be fitted to a waterproof, flat and even wall surface. The
two screws and wall plugs supplied are suitable for most solid wall installations.
Alternative fixing screws for panel structures are not supplied. Use both fixing
points to secure the shower, be sure to use fixings appropriate for the chosen
wall structure.
9.
When pipework enters the product from the rear through a hole in the wall,
provision must be made to prevent water ingress back into the wall structure.
10. Position the shower unit where the controls are 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 installation must not cause the
shower hose to be kinked during normal use.
