INSTALLATION
WARNING!
The mixer valve should be fitted only after all the pipework has been installed and ensure no
pipes or wires are behind where the screws will be required.
Do not modify or use jointing compounds on any of the pipe fittings. Do not solder fittings near
the mixer valve as heat can damage the valves or seals. Always flush the system prior to install-
ing the valve.
Before installing, make sure the mixer valve is kept in a clean place to prevent any rubbish etc,
getting into the openings while fitting the pipework.
•
The mixer valve is suitable for installation on a solid wall, a stud partition wall, dry lined wall
or fixing to a cubicle or panel.
•
The water pipes should be securely attached within the wall or panel to support the mixer
valve and prevent movement or water noise after installation.
•
The mixer valve hot water inlet has a red symbol next to the inlet and must be on the left
hand side with the outlet pointing upwards.
•
The mixer valve is designed to work at the same hot and cold water pressures. If this is not
the case a flow controller (disc with small holes) can be fitted to the higher pressure supply
to the valve. This is best done by testing each one to find out which gives the best results.
•
The mixer valve will be installed in such a position that the maintenance of the TMV
and its valves and the commissioning and testing of the TMV can be undertaken.
SITING OF THE MIXER VALVE
Position the mixer valve so that all controls can be comfortably reached while using the shower.
NOTE: Easily accessible suitable service valves (complying with Water Regulations
Advisory Service www.wras.co.uk). MUST be fitted as close as practical to the valve,
on the hot and cold water supplies to the shower as an independent means of
isolating the water supplies should maintenance or servicing be necessary. These
valves should not restrict the flow.
The supply pipework can be plumbed from above or below but must finish at the suitable
connections, which should be 155mm centers. If installing into a stud partition etc, the pipework
will need support.
Before fitting the mixer valve flush out the pipework in accordance with Water Regulations
Advisory Service (www.wras.co.uk).
