Commissioning
Before commissioning the solar hot water system, please
confirm the following:
• Collector(s) have been installed correctly
• Collector(s) have been covered
• Collector array has been adequately fixed to the roof
• Storage tank has been installed correctly
• Storage tank and collector array connections have
been completed
• The solar controller has been installed correctly
• Inlet piping and valves have been installed correctly
• Relief valve(s) have been installed and piped correctly
• Tempering valve has been installed correctly
• Piping between the storage tank and the collectors
has been installed correctly
• Gas continuous flow water heater has been installed
correctly (gas boosted only)
• Sufficient insulation has been installed on all hot
water piping
• The electrical supply is isolated to the hot
water system
• Electrical wiring has been completed and installed
correctly
• Electrical testing has been completed and
satisfactory results obtained
• Temperature sensors have been installed and
connected to the solar controller
The following steps are to be followed after the installation
of the solar hot water system to ensure its safety and
performance. If the hot water system cannot be setup to
perform correctly as specified in this manual, please call the
service centre for further instructions (number located in the
warranty section of this manual).
Filling the hot water system with water and checking
for leaks
At this stage, the power to the tank element and pump
station should be isolated (off). Fully open the cold water
isolation valve located on the inlet to the storage tank to
allow the system to begin filling with water.
Activate the temperature and pressure relief valve on the
storage tank in order to allow air to bleed out of the tank.

Once water begins flowing from the relief valve piping de-
activate the lever on the temperature and pressure relief
valve. The automatic air vent valve installed on the collector
array will allow air to bleed out of the solar hot water system.
Loosen the cap on the air vent valve to enable the air venting
function, then leave the cap loose after installation to allow
continued automatic air and steam venting as required. It
should not be necessary to manually bleed air from the top
of the collector (although it may take up to a few hours to
release all the air, depending on the installation). Check for
any water leaks on the storage tank, collector array and pipe
work connections, tightening or sealing as appropriate to
confirm the system is water tight.
In order to bleed air out of the hot water pipes into the
premises, open the nearest hot water tap or fixture to the
hot water system.
Once water has begun flowing freely from the hot water tap
or fixture, indicating that all air has been expelled from the
hot water pipes, close the hot water tap or fixture.
