Page 4: General Information
General Information This product has been tested to comply with the BS EN 1287:1999 (LP) and BS EN 1111:1999 (HP) thermostatic mixing valve standards. BS6700 recommends the temperature of stored water should never exceed 65ºC. A stored water temperature of 60ºC is considered sufficient to meet all normal requirements and will minimise the build up of lime scale in hard water areas (see Map of Hard Water Regions in the UK on page 27). -
