8.6 Flow settings:

The ow regulator should be set to 0.5 to 1.0 litre per minute per panel. A three-panel

installation is set to a ow rate of 1.5 to 3 litres per minute.

How to read the ow setter:

8.7 Pressure settings:

The maximum pressure is 6 bar. Once the system is pressurised keep the pressure

between 3 – 4 bar. With higher pressure inside the system, the glycol/mix will not

evaporate until temperatures of around 120°Celsius are reached. Pressurisation

therefore helps to prevent glycol degradation and enables more useful heat energy

to be applied.

8.8 Maintenance:

The double pump station does not require maintenance. It is fully controlled by the

digital controller. The customer should do a visual check every month for leaks,

signicant different readings on the temperature gauges and readings on

digital controller, pressure drop below red line on the pressure gauge can indicate a

leak on the system. The customer should be informed that uctuations in pressure

readings while the system is operating are perfectly normal. In case of any

unexpected changes, the customer must contact the installer immediately.

Note: A competent solar engineer should service the system 3 years after install, and

then every 2 years there after.
