Fixing the valve backplate to a wall
When locating and securing the valve backplate
(see exploded view) to a wall, it is important
to use No. 8 screws. Before marking mounting
hole locations, ensure that one of the set screws
mounted in the valve backplate is at the bottom.
Non-return valves
To protect your water system, non-return
valves are fitted inside the inlet elbows to the
sides of the valve body. These can be removed
and cleaned if required.
Testing
It is important to pressure check all
connections. During manufacture the internal
components and external joints of the valve are
pressure tested to 5 bar. However, installation
can affect the external joints. For this reason we
recommend that all connections to and from the
valve are pressure tested.
Access
It is important to leave suitable clearance and
access to the valve and connections for future
servicing.
Setting the ‘safe temperature’
To avoid damage, when setting the ‘safe
temperature’ the thermostatic cartridge spindle
must be turned by hand only. The spindle will
require only minor adjustment.
Turning the
spindle to the end of its travel and forcing it
beyond this point will cause internal damage to
the thermostatic cartridge.
Always fit the black plastic ‘temperature stop’
before fitting the ‘override’. One of the
functions of the temperature stop is to prevent
the thermostatic cartridge spindle being turned
beyond the end of its travel.
Not fitting the
temperature stop will result in damage to the
thermostatic cartridge.
