Commissioning the solar system
Until system filling and commissioning is complete:
Keep solar panels covered
do not plug in the solar controller / pump or connect a power supply to boost the
element until step 6
•
•
WARNING
if a gas boost is fitted, open the inlet and outlet water valves at the rinnai infinity but do
not connect the power supply at this point.
Open a hot tap at the sink.
Open the cold water inlet to the storage cylinder.
Keep the hot tap open until non-aerated water appears at the sink.
Taking care to avoid potentially scalding water, open the air bleed valve on the temperature
sensor pocket on the top right hand corner of the solar panel(s).
Plug in the power lead from the solar controller / pump. if the hot temperature sensor is
9
o
C hotter than the cold temperature sensor the pump should start. if this is not the case,
cool down the cold temperature sensor in a cup of ice. if this is still not sufficient to create
the 9
o
C differential, a spare hot sensor lead can temporarily be connected to the pump
controller and warmed until the pump starts.
Leave the air bleed valve open with the pump running until non-aerated water appears at
the bleed valve. Close the air bleed valve.
The coverings can now be removed from the solar panel(s).
Tape the cold sensor to the T on the inlet of the cylinder. Fit suitable insulation material
over the sensor and fasten in place.
Fit the pump and controller cover.
For an electric boost system, program the timer as required, set the thermostat to between
60 and 70
o
C and replace the element cover.
For a gas boost system, connect the rinnai infinity to power and gas, and commission in
accordance with the instructions supplied with the water heater.
