UK
This product has been designed and tested to comply with BS EN1287:1999 (LP-S)
and BS EN 1111:1999 (HP-S) Thermostatic Mixing Valves Standards.
Valves operating outside of the below conditions of use cannot be guaranteed as
type 2 valves.
Hot Water Maximum: 65˚C
Recommended 60-65˚C
Always maintain a 10˚C difference between hot system temperature and maximum
hot setting of valve.
Operating Pressure Range: Min. 1.0 bar, Max. 5 bar
When water pressure is higher than 5 bar a pressure reducing valve (not supplied)
must be fitted before the mixer. A setting of 3 bar is recommended.
This valve is suitable for gravity boosted, balanced high pressure and combination
boiler systems.
For gravity pumped systems use 22mm supply pipes and reduce to 15mm to
protrude through the finished wall.
Pump Installation:
PUMPS MUST NOT BE FITTED DIRECTLY TO A WATER MAIN.
REFER TO PUMP MANUFACTURERS INSTALLATION GUIDELINES.
Ensure there is adequate flow through the pump to activate the flow switches.
Combination boiler:
MUST have a minimum rating of 24kW (80,000 Btu) and be of the type fitted with
a fully modulating gas valve.
Boiler performance may affect outlet temperature.
Operating pressures:
Hot and cold supplies should be kept as even as possible in order to ensure the
maximum efficiency of the mixer.
