Connections:

• Inlet and outlet: ¾" flat faced male union.

• Note: 2 elbows and 1 straight union connectors are supplied, terminating in 22 mm compression connections.

• Standard connections are hot (left), right (cold).

Pressure/ Flow rates:

• Minimum dynamic supply pressure: 0.15 bar.

• Minimum flow rate: 3 litres/minute at mid blend.

• Maximum flow rate: 40 litres/minute at mid blend.

• Maximum pressure loss ratio: 10:1 (in favour of either supply).

• Maximum dynamic supply pressure: 5 bar.

• Maximum static pressure: 10 bar.

Note: Both hot and cold pressures should be nominally equal.

Temperature range:

• Factory pre-set maximum outlet temperature: 43°C.

• Minimum temperature differential blend to either supply: 12°C.

• Optimum temperature control range: 30–50°C.

• Minimum cold water temperature: 1°C.

• Maximum hot water temperature: 85°C.

Note: The mixing valve can accept temporary temperature excursions above 85°C without damage, however, operation at such elevated temperatures is not recommended. For safety reasons it is recommended that the hot water storage temperature is maintained at between 60°C and 65°C in ablutionary applications.
