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 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.
Completing the Commissioning of the Solar Circuit
29. 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.
30. Replace the lower and upper front covers of the solar
storage tank and the pipe cover to the underneath of
the gas booster.
31. Clean off the marks made on the side of the solar storage tank.
32. Remove the covers from the solar collectors.
33. Switch on the electrical supply at the power outlet to the solar storage tank.
