, or Local Agent.

Disinfection

In applications where system chemical disinfection is practised, chlorine can be used 

(calculated chlorine concentration of 50 mg/l (ppm) maximum in water, per one hour dwell 

time, at service interval frequency).  Such procedures must be conducted strictly in accordance 

with the information supplied with the disinfectant and with all relevant Guidelines/Approved 

Codes of Practice.
If in any doubt as to the suitability of chemical solutions, refer to:

inlet dynamic pressures nominally balanced to within 10% of each other during flow.
a differential of 15-35°C between the blend setting and either supply.
daily usage of 1-6 hours.
installation and usage environment not subject to extremes of temperature, unauthorised 

tampering or wilful abuse.

Normal Operating Conditions 

are considered as:

Specification

Pressures

Minimum Dynamic Supply Pressure: 

0.1 bar

Maximum Dynamic Pressure: 

8 bar

Maximum Supply Static Pressure: 

10 bar

Maximum pressure loss ratio*: should not exceed 10:1 in favour of either supply during flow.
Maximum pressure loss: inlets to outlet is 5.6 bar, which equates to maximum 120 l/min flow 

rate at mid blend.

Note!

 Pressure loss is the pressure drop between the inlets and the outlet of the mixing valve 

when flow is taking place.

* Pressure Loss Ratio is determined by subtracting the resistance of the outlet pipework and 

outlet fittings from the dynamic pressures of the hot and cold water at the inlets of the mixing 

valve. This is at its extreme when the mixing valve is used at its lowest flow-rate and when 

the maximum inequality occurs in the pressure of the hot and cold water supplies.
