REMOVING AND INSPECTING MIXER CARTRIDGE
1
. Remove handle assembly
−
Unscrew the tamper proof screw from handle.
Pull out handle assembly from the body
2. Remove flange and faceplate
−
Unscrew the three screws and pull out the flange
and faceplate from unit.
Do not remove the
outer faceplate.
3. Isolate the shower
−
It is recommended the shower is isolated at
supply.
−
To isolate the shower loosen the isolators in an
anti-clockwise direction until they are touching
the circlips. This closes the shut off valves.
−
Open the valve and check if there is a flow.
4. Remove cartridge nut and check cartridge
−
Unscrew cartridge and remove from body. Check
the cartridge for wear and damage. Replace if
required (replacement cartridge available through
your supplier).
−
Check and clean the body of all debris.
5. Re-assemble
−
Re-assemble, by reversing steps 4 to 1.
−
To re-open the shut off valves tighten the flow regulator/check valve/filter units until tightened (do not over
tighten) and refit the two clips.
−
Check for leaks and correct operation.
Note:
Before tightening the flange make sure the handle fits correctly. Fit screws into flange and finger tighten. The flange should still
be able to move. Slide the handle onto spline and move the flange until central to the handle. Remove handle and tighten the screws
(it is best to tighten the screws in sequence a little at a time to avoid the flange moving). Refit handle.
