SPECIFICATION
Normal Operating Conditions
are considered as:
-
inlet dynamic pressures nominally balanced to within 10% of each other during
flow
-
a differential of approximately 50°C between the hot and cold inlet
temperatures, and with differentials 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.
Other Applications
For information on other specific applications or suitability, refer to Kohler Mira Ltd,
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 Kohler Mira Limited,
or Local Agent.
Operating Parameters
For Type 3 valves the supply conditions specified in
Type 3 Valves - Application
take precedence over the operating parameters which follow.
Pressures/Flow Rates
For
optimum
performance, dynamic supply pressures should be nominally equal.
Recommended Minimum Flow Rate: 3 litres/minute
at mid-blend with equal
dynamic supply pressures
.
Recommended Maximum Flow Rate: 35 litres/min
at mid-blend (which equates
to a maximum pressure loss of 1.9 bar).
Maximum Pressure Loss Ratio*:
should not exceed
10:1,
in favour of either supply,
during flow.
Recommended Minimum Dynamic Supply Pressure: 0.15 bar (0.2 bar
healthcare).
