Refilling system
DO NOT switch on the immersion heater(s) or boiler until the system has been completely refilled.
Close the drain tap. With the hot tap open, turn on mains water supply. When water flows from the hot tap allow to flow for a
short while to purge air and to flush through any disturbed particles. Close hot tap and then open successive hot taps in system to
purge any air. The electrical supply can now be switched on.
Check solar heat transfer fluid
The heat transfer fluid must be checked every year with regard to its antifreeze and pH value. (7.0 - 9.5)
• Check antifreeze using antifreeze tester. Target value is approximately -21 deg C (40% concentration).
• Replace fluid if necessary.
Maintenance of the collector
The collector or the collector array must be checked/serviced annually to check for any damage, leaks or contamination.
In areas where there may be a build up of dirt on the collector, only non-abrasive cleaning materials and methods should be used
to clean the collectors and mounting system components.
Benchmark™
On completion of any maintenance or service of the Megaflo Eco SolaReady, the Benchmark™ “Installation, Commissioning and
Service Record” should be filled in to record the actions taken and the date the work was undertaken (page 50).
Fault finding
The Fault finding flow diagrams (Fig 27) will enable operational faults to be identified and their possible causes rectified. Any work
carried out on the Megaflo Eco SolaReady unvented water heater and its associated controls MUST be carried out by a competent
installer for unvented water heating systems. In case of doubt contact the Megaflo Eco SolaReady Service Department.
