Water Supply Requirements
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. 0.15 bar, Max. 5.0 bar
Operating pressures: Hot and cold supplies must be equal pressures in
order to ensure the maximum efficiency of the mixer.
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 stored, gravity boosted (pumped),
balanced high pressure and combination boiler systems.
For gravity and gravity pumped systems use 22mm supply pipes and
reduce to 15mm for connection to the shower valve.
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.
N.B. Boiler performance may affect outlet temperature.
Not suitable for mixed water supplies, i.e. gravity hot and
mains cold.

Cold Water Minimum: 5˚C
