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
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.
Replace the lower front cover of the solar storage tank and secure by refitting the screw into the lower

front jacket.
Clean off the marks made on the side of the solar storage tank.
