COMMISSIONING

Remove Closed Circuit Fluid Level Hose
28. Remove the clear hose from the solar storage tank when satisfied the commissioning procedure is
complete.
To remove the hose:
 Ensure the heat exchanger drain valve is closed.
 Remove the hose from the side of the storage tank
and place the end into a container to collect the
closed circuit fluid in the hose.
 Replace the plug into the free end of the hose and
lay the hose flat on the ground.
 Loosen the hose clamp, if fitted, and carefully
remove the hose and hose clamp from the heat
exchanger drain valve fitting, ensuring there is no
spillage of any remaining closed circuit fluid.
Clean up any spillage of closed circuit fluid.
 Place the open end of the hose into the container and recover the remainder of the closed circuit
fluid from the hose.
Note: The closed circuit fluid contains food grade additives (rust inhibitor, anti-freeze agent, colour)
and is harmless to the environment. However, it is good practice to recover any excess closed
circuit fluid and remove from site for appropriate disposal.
Completing the Commissioning of the Solar Circuit
29. Reconnect the hot sensor plug into the hot sensor
connection socket on the control board located behind
the lower front cover.
It is important 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, will not operate
and no solar gain will be achieved.
30. Replace the lower front cover of the solar storage tank and secure by refitting the screw into the lower
front jacket.
31. Clean off the marks made on the side of the solar storage tank.
32. Remove the covers from the solar collector.
33. Switch on the electrical supply at the power outlet to the solar storage tank.
