John Guest Truma Combi 4/6 & C6D Frost Control Water Fitting Kit - 36100-02

The drain/safety valve, which can operate without power. Drains the boiler automatically via a drain nozzle when the temperature drops to approx. 3 °C (risk of frost)

• Drain valve opens even in the event of overvoltages
• Emptying takes place intermittently to prevent the drain from freezing
• If necessary, the drain valve can also be opened manually
• The valve can only be closed again when the temperature of the FrostControl rises again to a level far from freezing point (approx. 7 °C)
• Operation without power does not burden the on-board battery
