Warning: A non-return valve MUST BE installed on the cold water line to the solar storage tank AFTER
the cold water branch to a temperature limiting device prior to an open circuit system.
If a combination isolation valve and non-return valve (duo or trio valve) is installed on the cold water line to an
open circuit solar water heater and the cold water line to the temperature limiting device branches off after this
valve, then a second non-return valve must be installed between the cold water branch and the solar storage
tank.
If a pressure limiting valve is installed on the cold water line to the solar water heater and the cold water line
to a temperature limiting device branches off before this valve or from another cold water line in the premises,
then a pressure limiting valve of an equal pressure setting may be required prior to the temperature limiting
device.
Refer to the installation instructions supplied with the solar storage tank for further information on the
installation of the cold water valves in the cold supply pipework prior to the solar storage tank.
