Installation Manual
Water Regulations Requirements :
It is important to ensure that the water supplies to your taps and mixers are connected in
accordance with the water regulation (WRAS) requirements and good plumbing practice.
It is good plumbing practice that the supplies of hot and cold water to the Bathroom fitting should
be equal (balanced) pressure in order to provide a consistent flow. Supplies should be from a
common source, either mains or tank fed. If supplies are not equal pressures then a Non Return
Valve ( Check Valve ) should be fitted on the hot inlet.
It is our recommendation and good plumbing practice that a service valve should be installed in the
inlet supply lines to allow isolation of the Bathroom fitting.
1. Make sure both Hot and Cold supplies have been isolated and drained.
2. Rotate the spout and body so the tap is facing forwards. The spout screw on the tap indicates
the rear of the body. Typically the hot water should be on the left-hand side of the tap.
Before proceeding the assmbly and installation, prepare a smooth surface where you can lay all the
particulars being sure not to damage them.
SYSTEM REQUIREMENTS
To ensure the optimum performance and customer satisfaction please adhere to the following:
• Flush out all pipe work prior to installation.
• Minimum flow pressure for satisfactory operation: (Hot and Cold) 0.2 Bar 20kPa
• Maximum static water pressure 10 Bar 1,000kPa
• If the water pressure exceeds or is likely to exceed 10 Bar 1,000kPa, an approved pressure
limiting valve must be fitted.
• Maximum hot water temperature 80ºC
• If the water temperature exceeds 80ºC an approved tempering valve must be fitted.
• Installation should comply with relevant local authority requirements.
Failure to comply with the above will void all warranties.
Tools required.

Installation Instructions
Please note these instructions are for the hot and cold inlet pipes to enter the mixer from below the
mixer and the outlet to the shower at the top.
If the inlet pipes are located above the mixer rotate the mixer 180 degrees and fasten as indicated
below.
To ensure correct operation of the valve the installer will need to remove the chrome cover sleeve from
the mixer by unscrewing the two grub screws holding the sleeve in place and undoing the large brass
nut holding the thermo cartridge in place, remove the cartridge and rotate the cartridge 180 degrees and
re-install, ensuring a water tight seal is maintained. Re-position the cover sleeve with the temperature
indication mark facing upwards and then retighten the grub screws to fasten the cover sleeve to the
thermomixer body.
1) Fit plug (not supplied) to shut off bottom outlet
2) Position the thermostatic mixer against a mounting board within a maximum (100mm) and a
minimum (70mm) depth allowed from the back of the mixer and the face of the wall lining and fix.
3) Connect the hot and cold water supplies to the mixer, matching the ot and cold inlet pipes to the
correct hot and cold inlets on the thermo mixer.
4) Connect the pipe work and the volume control valve to the top outlet of the thermostatic mixer, and
the shower rose-slide shower set pipe work to the outlet of the volume control valve.
5) Pressure test by plugging outlet pipes: turn on the water supply and the volume control valve. Once
all joints are proved pressure tight turn off the volume control valve and break the seal on the temporary
outlet plug.
6) Cut an access hole 140mm x 70mm in the wall lining for the mixer; fit wall lining.
7) Apply a thin bead of silicone sealant to the back of the faceplate ensuring a continuous seal is
maintained around the edge of the faceplate.
8) Slide the faceplate over the mixer ensuring the faceplate is correctly positioned on the wall and
covering the access hole.
To fit the handle:
Please note the thermostatic valve has been factory set at approximately 38° C when the handle is
positioned on the mixer at the safety button position. (This will be dependant on the hot and cold water
inlet temperatures).
1) Fit the handle to the valve with the blade of the handle facing in a downward (6 o clock) position and
ensuring the lug on the underside of the handle is just touching the safety button stop on the mixer.
2) Turn on the water supply and test the temperature being delivered from the thermostatic mixer.
To increase the temperature being delivered at the safety button position, remove the handle and turn
the spindle of the thermostatic mixer anticlockwise a few degrees and retest the temperature.
Likewise to decrease the temperature turn the spindle clockwise a few degrees and retest te
temperature.
When the appropriate temperature has been achieved align the handle with the handle facing in a
downward (6 o clock) position and ensuring the lug on the underside of the handle is just touching the
safety button stop on the mixer, tighten the grub screw under the handle.
