sensor may be mounted

either side of the fitting

In healthcare applications the height of the fixation holes above the

“waste appliance” should be selected to create the recommended

“activity space” as defined in HBN 00-10 Part C, typically

150mm – 200mm for a basin and 250mm – 300mm for a surgeon’s

scrub up trough

IMPORTANT: Prior to installing mixer, ensure that any

existing

thermostatic

mixing valves (TMVs) that may be fitted are removed
