Commissioning the Solar Circuit
To commission and check the solar circuit:
1. Switch off the electrical supply at the power outlet to the solar storage tank.
If the pump has been operating, wait five minutes to allow the drain back of the closed circuit fluid
in the solar circuit.
2. Cover the solar collectors with an opaque material to prevent solar gain during the commissioning
process.
3. Remove the lower and upper front covers from the solar storage tank.
The solar monitor located on the lower front cover is
connected to the solar control module by a ribbon
cable. The ribbon cable has sufficient length to enable
the removal of the lower front cover and for it to be
set to one side of the opening without disconnecting
the ribbon cable from the solar control module.
The ribbon cable can be disconnected from the solar
control module if it is necessary to remove the lower
front cover completely from the work area in front of
the solar storage tank.

4. Ensure the isolation valve in the pipe work between
the outlet of the heat exchanger and the solar pump,
located behind the lower front cover of the solar
storage tank, is fully open.

5. Attach the clear hose to the solar circuit.
To attach the hose:
Ensure the heat exchanger drain valve is closed.
The heat exchanger drain valve is located
adjacent to the solar pump, behind the lower front
cover of the solar storage tank.

Attach one end of the hose to the hose tail
connection.
It may be necessary to secure the hose with a
hose clamp.
Plug the free end of the hose.
Affix the hose securely in a vertical orientation to
the front of the solar storage tank using tape,
adjacent to the text, “MINIMUM FLUID LEVEL
WITH PUMP OPERATING”.
