System commissioning
Ensure that all vacuum tubes have been filled with water before they were inserted into the main
water tank. If this was not the case, make sure that all vacuum tubes are completely covered to
avoid heat build-up. When confident that the vacuum tube temperature is below 40 degrees, the
main water supply to the solar water heater can be opened.
Keep electrical power to the backup element switched off at all times.
Flush all plumbing pipes before connecting the solar water heater.
The cold water will fill the tank and all excess air will exit through the safety overflow port. The
cistern tank valve will close when the main tank is full.
Check all piping and joints for water leaks.
Turn on the backup element and check if water is heating up after 10 or more minutes. Make sure
the main tank is filled before turning on the backup element.
