INSTALLATION
General
Installation must be carried out in accordance with these instructions, and must be
conducted by designated, qualied and competent personnel.
The installation must comply with the “Water Supply Regulations 1999 (Water Fittings)”
or any particular regulations and practices, specied by the local water company or
water undertakers.
Note! Make sure that all site requirements correspond to the information given in
section: ‘Specications’. For Type 2 Valves see also supply conditions in section:
‘Type 2 Valves’.
1. The Thermostatic Mixer must not be installed in an area where it may freeze.
2. For stud partitions alternative xings may be required.
3. Isolating valves must be installed close to the Thermostatic Mixer for ease of
maintenance.
4. Pipework must be rigidly supported and avoid any strain on the connections.
5. Pipework dead-legs should be kept to a minimum.
6. Supply pipework layout should be arranged to minimise the effect of other outlet
usage upon the dynamic pressures at the Thermostatic Mixer inlets.
7. Inlet and outlet threaded joint connections should be made with PTFE tape or
liquid sealant. Do not use oil-based, non-setting joint compounds.
8. To eliminate pipe debris it is essential that supply pipes are thoroughly ushed
through before nal connection.
9. Decide on a suitable position for the
Thermostatic Mixer. The position
of the Thermostatic Mixer and the
Sh ower Fitti ngs mus t provi de a
minimum gap of 25 mm between
the spill-over level of the shower
tray/bath and the handset. This is to
prevent back-siphonage. For further
information on the installation of your
shower ttings, refer to the Fittings
Installation and User Guide.
Not e ! On ly use shower fit t ings
