Specification - Mira Montpellier Installation, Operation, Maintenance Manual

Normal Operating Conditions
- inlet dynamic pressures nominally balanced to within 10% of each other during
flow.
- a differential of approximately 50
and with differentials of 15-35
- daily usage of 1-6 hours.
- installation and usage environment not subject to extremes of temperature,
unauthorised tampering or wilful abuse.
Disinfectants
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 Ltd, or
Local Agent.
Operating Parameters
For type 3 valves the supply conditions specified in Type 3 Valves-Applications
take precedence over the operating parameters which follow.
Pressures And Flow Rates
For optimum performance, maintained supply pressures should be nominally
equal.
Maximum Pressure Loss Ratio: 10:1
Maximum Static Pressure: 10 bar.
