Vacuum Tube Installation
The vacuum tubes supplied with the tank are highly efficient. Left in the sun
and left dry, they will easily attain an internal temperature of over 250°
Celsius – a temperature that can cause both damage and injury.
Fig 11
Each tube should be removed from its packaging ONLY
when one is ready to install it. Tubes should ALWAYS be
installed filled with water - to avoid the possibility of
heat damage to the tank.
CAUTION
Ensure cold water is filled early in the morning when the
temperature within the tubes is low to avoid damage to
the glass tubes.
CAUTION
13. After the installation, allow the solar water heater to heat the water for a day
of sunlight before using the hot water.
14. The solar water heater has a provision for back-up electrical heater. It should
be installed by a trained electrician providing a proper earth and protecting
the cable connections from water and moisture.
6. SYSTEM COMISSIONING
On installation or after service it is important that the system is primed. This is
carried out by first opening the incoming feed followed by the bleed cock
and then observing when all air is expended from the bleed outlet. Proper
priming is important or else the unit will not operate at full efficiency.
