Remove Closed Circuit Fluid Level Hose
29.
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 remaining 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 the 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
30.
Reconnect the hot sensor lead to the connecting plug
located on the tab in the upper front cover opening.
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.
31.
Replace the lower and upper front covers of the solar
storage tank.
If the ribbon cable from the solar monitor has been disconnected, reconnect it to the solar control
module prior to replacing the lower front cover.
32.
Clean off the marks made on the side of the solar storage tank.
33.
Remove the covers from the solar collectors.
34.
Switch on the electrical supply at the isolating switch to the solar storage tank.
