Installation
General
1.
Installation of the product 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.mirashowers.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.
Note:
These should still be fitted even for products with integrated isolators.
DO NOT
use integral isolating elbows for flow regulation. The product should
be installed with nominally equal inlet supply pressures.
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.
Suitable Plumbing Installations
The Thermostatic Mixer can be installed with all systems with balanced pressures.
Mixed gravity and mains supplies are not recommended.
