Check the closed circuit fluid is circulating around the solar circuit.
11.
To check circulation:
 Listen for the trickling sound of the closed circuit fluid returning into the heat exchanger by placing
your ear against the side toward the top of the solar storage tank.
If the fluid is circulating around the solar circuit, a trickling sound will be heard as the fluid returns
back into the heat exchanger.
If no trickling sound is heard, check:
the hot sensor lead is disconnected at the solar storage tank.

If connected, disconnect the hot sensor lead at the solar storage tank
the isolation valve in the pipe work between the outlet of the heat exchanger and the solar

pump, located behind the lower front cover of the solar storage tank, is fully open.
Warning: Switch off the electrical supply at the power outlet to the solar storage tank
before entering the area inside the solar storage tank behind the front cover.
If closed, open the isolation valve on the outlet of the heat exchanger
there is no leakage from the solar circuit. It is important to check all of the solar circuit pipe

work, including in the roof space and on the roof.
If leaking, rectify any leaks in the solar circuit.
the height from the base of the storage tank to the top of the collectors has not exceeded the

maximum allowable height.
the length of solar cold and solar hot pipe has not exceeded the maximum recommended pipe

length.
If the maximum allowable height or the maximum recommended pipe length has been
exceeded, it may be necessary to relocate the solar collectors to either a lower level or closer
to the solar storage tank, or install a second solar pump, or relocate the solar storage tank
closer to the solar collectors. Refer to
12. Mark the dynamic level of the closed circuit fluid in the
hose on the side of the solar storage tank with a non
permanent marker when satisfied the solar circuit
circulation is operating satisfactorily.
