Safety instructions
NOTE: In the event of leaks in the water pipework close the
main cold water stop valve. This is often located under a
kitchen sink.
IMPORTANT: A thermostatic mixing valve must be fitted to
the outlet of the cylinder and can be adjusted to the desired
domestic hot water temperature by an installation or service
engineer. Otherwise there is a risk of scalding as the cylinder
outlet temperature at the taps could be up to 85°C.
IMPORTANT: Risk of damage! Do not remove or modify any
components of the solar cylinder.
In the unlikely event of a malfunction occurring of the Flurocyl,
such as hot water flowing out of the temperature and pressure
relief valve, switch off the boiler and the immersion heater and
contact Glow-worm or your installer.

Frost protection of the twin coil solar cylinder
You must drain the solar cylinder completely if it is to be shut
down in a room prone to frost. It is drained at the cold water
inlet with a T-piece with tap to be provided by the installer.
Also drain all heat exchangers which are not filled with solar
fluid.
