3. Join with solar loop pipework and associated components

4. Install controller, sensors and electrical supply

5. Commission System

6. Fit tubes

7 Bleed air.

Commissioning the System

To fill the solar loop, premix the antifreeze/water to 40% concentration in a 'hanging basket watering device' available from any garden centre. Remove the nozzle/lance of the device - there should be a threaded connector. You will then need to obtain an adaptor from a plumbers merchant to adapt this to the filling loop supplied with the pressure system kit included within your solar kit. (on mine, it was something like a BSP 1/2 to BSP 3/8 male/make adaptor). You can now connect the watering device to the filling loop, and by pumping the handle to pressurise the reservoir, it will force the antifreeze solution into the system. Continue to fill until the pressure reaches 1bar, ensuring that all air is bled out of the highest point in the system (usually by loosening one of the compression fittings on the panel itself)
