COMMISSIONING
58
Co
To commission and check the solar circuit:
1. Switch off the electrical supply at the isolating switch 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.
