7. IMPORTANT INSTALLATION INFORMATION
Before proceeding with the installation check all the
components in the component list are present.
WARNING!
The shower must not be positioned where
it will be subject to freezing conditions.
The mixer valve should be fitted only after all the
pipework has been installed. Isolating valves should
be fitted to both hot and cold water supplies for
servicing purposes.
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 seals. Always
flush the system prior to installing the valve.
Before installing, make sure the mixer valve is kept
in a clean place to prevent any debris getting into the
openings while fitting the pipework.
n
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.
n
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.
n
The mixer valve hot water inlet has a red symbol
next to the inlet and must be on the left hand side. If
the mixer valve you are fitting is with a riser rail the
outlet should point down, if the mixer valve is for an
overhead the outlet should point upwards.
n
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.
n
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.
Before fitting the mixer valve flush out the pipework in
accordance with Water Regulations Advisory Service
(www.wras.co.uk).
The MX Options range of thermostatic mixer valves is
suitable for use with the following systems:
Gravity Fed, Gas Combination Boiler, Pumped Gravity,
Mains Pressure (Thermal Store), Unvented Systems.
NOTE: On gravity systems the minimum distance
from the underside of the cold water storage tank to
the shower head must be 1 metre.
