This is at its extreme when the mixing valve is beingused at its lowest flow rate and when the maximum inequality occursin the pressure of the hot and cold water supplies.WeightProduct Gross Weight (Kgs) Total PackagedWeight (Kgs)Meynell V8/3 B 3.500 3.730Meynell V8/3 BL 3.500 3.890Meynell V8/3 B - biv 5.500 5.993MaterialsBody: DZR brass chrome plated.Temperature RangeFactory preset maximum outlet temperature: 42°C.Minimum temperature differential between hot inlet and preset outlettemperature: 10°C.Optimum temperature control range: 35°C - 45°C.Maximum hot water temperature: 85°C (for safety reasons it isrecommended that hot water storage temperature is maintained atbetween 60°C to 65°C in ablutionary applications).The performance specification outlined below is achieved with outletblend temperature set between 35°C - 45°C and supplies of 15°Ccold and 65°C hot with nominally equal pressures:Outlet blend temperature is maintained within 2°C with a 10°C changeKohler Mira LimitedCromwell Road, CheltenhamGloucestershire, GL52 5EPSpecification EnquiriesTel: 01242 282527, Fax: 01242 282404Email: rada_technical@mirashowers.comwww.radacontrols.comRada is a registered trademark of Kohler Mira Limited.The company reserves the right to alter product specification without notice.© July 2006 Kohler Mira Limited.
