Page 9: Installation
Installation Suitable Plumbing Systems Gravity Fed: The thermostatic mixer must be fed from a cold water cistern (usually fitted in the loft space) and a hot water cylinder (usually fitted in the airing cupboard) providing nominally equal pressures. Mains Pressurised Instantaneous Hot Water System (Combination Boiler): The thermostatic mixer can be installed with systems of this type with balanced pressures. (Recommended Minimum Maintained Pressure: 1.0 Bar). There is no flow adjustment with this product. A 12 l/min flow regulator is supplied and is recommended to be fitted in High Pressure systems(see Flow Regulator Installation) Unvented Mains Pressure System:... - Page 10 Decide on a suitable position for the Mixer. The position of the Mixer and the Shower Fittings must provide a minimum gap of 25 mm between the spill-over level of the shower tray/bath and the showerhead (refer to illustration). This is to prevent back-siphonage. For further information on the installation of your Shower Fittings, refer to the Fittings Installation and User Guide. Note! Only use Shower Fittings recommended by the manufacturer or supplier.

Page 20: Maximum Temperature Setting
Commissioning Maximum Temperature Setting Before using the shower, the maximum temperature must be checked to make sure that it is at a safe level. It has been preset to a safe showering temperature under ideal conditions at the factory, appropriate for most systems. However, site conditions and personal preference may make it necessary to reset this temperature. Note! Make sure that the hot water temperature is at least 55°C and that there is sufficient supply. 1. Turn on the shower to the maximum temperature (i.e. fully anticlockwise) and allow the temperature to stabilise. - Page 21 13. Refit the handle trim. 14. Fit the handle using washer and screw. Careful! Ensure that washer is assembled when refitting the handle as this could lead to corrosion. 15. Tighten the screw to secure the handle.
