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.
