4.2.1 Fast Fit Fixing Kit (See Fig.1a)
4.2.1.1 Identify all components and check for completeness, particularly before
arranging fitting.
NOTE: - THE fixing centres are a NOMINAL DISTANCE of 150mm, therefore before drilling
holes for the supply pipes check the centre dimension of the actual product to be used.
4.2.1.2 Inlet pipes need to terminate with at least 30mm of 15mm diameter pipe (not
supplied) protruding through the finished wall surface.
Important:- Water supplies to the mixer must be with the Hot on the left, & Cold on the
right when viewed from the front .
4.2.1.3 Place the wall plate (2) over the pipe and mark the hole centres, drill two holes
to suit the wall plugs (1) and insert the wall plugs into the freshly drilled holes in the
wall.
4.2.1.4 Place the wall plate (2) with onto the wall and tighten up the screws until
secure. Place the olive (3) onto the protruding 15mm pipe. The pipe needs to protrude
past the olive by 5mm maximum.
4.2.1.5 Screw the fixing bridge (4) onto the wall plate (2) using a 22mm a/f spanner,
holding the wall plate (2) with the flats provided with a 47mm spanner – DO NOT

4.2.2 Bar Shower Body (See Fig. 1b)
To fit mixer body to the wall. Place the filter washers (6) into the connecting nuts (7)
and tighten to the fixing bridge (4 on page 3. Fig. 1a) using the connecting nuts (7)
which are secured to the mixer body.
5. Setting
5.1 The maximum temperature (beyond the 38°C click) can be adjusted to suit site
conditions or user preference. To adjust this, follow this procedure:
5.2 Position the temperature control handle to click stop point and turn on the flow
handle control handle letting the water run long enough to ensure that the hot water
supply is at its maximum temperature.
5.3 The shower has been factory set to 38oC at the click position with balanced supply
pressures of 0.5 Bar.
5.4 Whilst the water is flowing remove the temperature control handle (10) and shroud
(12), by pulling the handle off the spline adaptor (11).
5.5 Turn the spline adaptor (11) until the required maximum temperature is achieved
(the spline adaptor many need to be reposition to allow the head to line backup with
the body of the shower), anti-clockwise to increase the temperature and clockwise to
reduce it.
5.6 Important: Refit the shroud and handle and shroud so that the stop pin in the handle
(10) fits inside the rim of the white nylon stop ring (15).
5.7 Push the shroud (12) and handle back on and turn clockwise. The handle should
click. This is quite normal.
5.8 Turn off the flow at the flow control handle.
6. Operation
6.1 On / Off - Flow Control
There are two control handles on the shower. Turn the flow control handle (left)
anti-clockwise to turn on and increase the flow, and clockwise to decrease and turn off.
The temperature control handle (right) is turned anti-clockwise for hot, clockwise for
cold and features a ‘temperature click notch’. The ‘click’ is factory set to 38oC, but can be
over ridden by turning the handle anticlockwise past the click stop position.

7. General Fault Diagnosis
7.1 If your valve fails to function correctly, the following should be checked:
7.1.1 Check that the hot and cold connections are the correct way around. Hot on the
left, cold on the right when viewed from the front.
7.1.2 Ensure that the hot water temperature is adequate. The recommended minimum
temperature is 60°C.
7.2 If your shower will not turn off:
7.2.1 Check ceramic disc valve is free of debris.
7.3 If your shower has a low flow rate.
7.3.1 Check that the filters (6) are not blocked.
8. Cleaning & Maintenance
8.1 Cleaning
Your fitting has a high quality finish and should be treated with care to preserve the
visible surfaces.
All surface finishes will wear if not cleaned correctly, the only safe way to clean your
mixer is to wipe with a soft damp cloth. Stains can be removed using washing up liquid.
All bath cleaning powders and liquids will damage the surface of your fitting, even the
non-scratch cleaners.
8.2 Regular Maintenance
We advise that the valve is regularly serviced, particularly in hard water areas. It is also
important to clean the handset regularly in hard water areas to maintain an even
spray/flow of water.
NOTE: ISOLATE THE WATER SUPPLY TO THE SHOWER VALVE.
8.3 Cartridge Removal (See Fig. 1b)
8.3.1 Remove the temperature control handle (10) and shroud (12), by pulling the
handle off the spline adaptor (11).
8.3.2 Unscrew the cartridge (13) anticlockwise.
8.4 Cartridge Maintenance
8.4.1 Place the cartridge in a bowl and carefully add some hot water (just off the boil)
and vinegar to de-scale the cartridge. Leave until the water has cooled.
8.4.2 Then remove the cartridge and rinse with clean water.
