If the caravan is not being used during the frost period, the Truma boiler must be drained as follows:
– Disconnect the power to the water pump (main switch or pump switch).
– Open hot water taps in the bathroom and kitchen.
– Open drain valve: lever vertical, position (f).
– The boiler will now be drained directly to the outside via the drain valve. Make sure that all the water is drained (10 litres).
Remember that we do not accept warranty claims for frost damage.
