Other Applications
For information on other specific applications or suitability, refer to:
rada_technical@mirashowers.com , 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.
