4. FILLING AND COMMISIONING THE SYSTEM
Do not turn on electric power until the whole system has been filled with water and a
satisfactory Megger reading is obtained by a qualified person.
SOLAR STORAGE TANK AND WATER HEATER
Follow instructions supplied with the heater. Note that it is necessary to provide a properly
drained safe-tray under heaters located where leakage may cause damage.
When locating the water heater, ensure the installation does not compromise the structural
integrity of the building.
Note: A Tempering Valve must be fitted in accordance with Australian Standards and
other State and Council regulations.
Turn on a hot water outlet tap, preferably the one furthest from the heater. DO NOT purge
through the PTR
valves. Open the mains cold water supply valve so that air is displaced from
the water heater and replaced with water. The hot water outlet tap should be left on until the
water flowing from it flows steadily without spurts. Turn off the hot water tap and allow the
system to pressurize. Check the system for leaks. Repair if required.
SOLAR PANELS
The solar panels must only be filled when they are cold, so it is important to ensure
that the panels are fully covered for a suitable time beforehand. Filling hot panels
may cause injury by scalding.
Turn on the mains water supply and ensure the water heater is full of water and all of the hot
taps are turned off. Turn on the circulating pump either by the manual override or by plugging
it directly into a power point. Allow the system to pressurise. Check for leaks and rectify if
required.
Note. Air in the system will prevent circulation so it is important that all air be removed from the
solar panel circuit. The air bleed valve installed at the top of the panels needs to be checked to
ensure the Air Relief valve top is opened and that when the pump operates the valve seals
properly when the pump is operating. This can be done by listening to the valve to ensure air
is not entering the pipe work. Let the pump run for 3-5minutes if the air is still bubbling into the
tank at this stage the valve may not be sealing or there is another fitting requiring tightening.
Remove covers from solar panels.
WARNING
– on a sunny day, if the solar panels are not covered during this operation,
the water flowing from the air bleed valve can be extremely hot causing steam and
possible scalding. Ensure sufficient precautions are taken to prevent injury to nearby
persons.
