6.  Open the heat exchanger drain valve and remove the 

plug from the end of the hose. 

The closed circuit fluid will flood the hose to the static 
level of the closed circuit fluid inside of the heat 
exchanger. 

7.  Mark the static level of the closed circuit fluid on the 

side of the solar storage tank with a non permanent 
marker.

8.  Disconnect the hot sensor lead from the connecting 

plug located on the tab in the upper front cover 
opening. 

It is important, at the end of this procedure when the 
commissioning and checking of the solar circuit is 
complete, to reconnect the hot sensor lead, otherwise 
when the electrical supply is switched on, the solar 
pump will deactivate after one hour and the solar 
control unit will then enter a fault mode and no solar 
gain will be achieved. 

9.  Switch on the electrical supply at the power outlet to the solar storage tank. 

 Warning: Take care not to enter the area inside the solar storage tank behind the front cover 

whilst the power is on as the electrical circuit will be live. 

The pump will activate and commence pumping closed circuit fluid around the solar circuit. 

The level of the closed circuit fluid in the clear hose will slowly drop to the dynamic operating level. 

Allow the pump to operate for three (3) minutes (one and two collector systems) or for five (5) 
minutes (3 collector system) to allow the solar circuit to fill with closed circuit fluid and stabilise. 

Note: The solar pump will operate for one hour with the hot sensor lead disconnected, before 
automatically turning itself off
