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 pump access and upper electrical 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 pump access cover.
Note: Care should be taken when reconnecting the ribbon cable to the solar
control module to ensure the side of the connecting plug with the yellow label is
facing toward the pump access opening. The connecting plug is non polarised
and if it is connected with the side of the connecting plug with the yellow label
facing away from the pump access opening, the functions of the green and red
LEDs will be reversed. This will result in the red LED flashing instead of the green
LED at solar pump start up.
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.
