Unvented mains pressure system The Thermostatic Mixer can be installed with a unvented, stored hot water cylinder. Mains pressurised instantaneous hot water system (thermal store) The Thermostatic Mixer can be installed with systems of this type with balanced pressures. Pumped system The Thermostatic Mixer can be installed with an inlet pump (twin impeller).
INSTALLATION General The Mixer must not be installed in an area where it may freeze. For stud partitions alternative fixings may be required. Isolating valves must be installed close to the Mixer for ease of maintenance. Pipework must be rigidly supported and avoid any strain on the connections. Pipework dead-legs should be kept to a minimum.

COMMISSIONING Maximum temperature setting This thermostatic shower control has been fully performance tested and the maximum temperature has been pre-set to approximately 42°C under ideal installation conditions at the factory. Site conditions and personal preference may dictate that the maximum temperature has to be reset. To reset the maximum temperature ensure that an adequate supply of hot water is available at a temperature at least 10°C in excess of that required from the shower control.
OPERATION This thermostatic shower control has a single sequential lever. The shower control is turned on by turning the control lever anti-clockwise. The shower control is turned off by turning the control lever clockwise. When the control lever is turned on (anti-clockwise) the sequence is: Cold water Warm water...
