HOW TO USE YOUR CARAVAN’S EQUIPMENT
4. Activating Water Heater Timers
Operating Instructions - Drain Valve
The Water Heater must be drained before travelling or if it is not being used for a period of more
than 3 days, or if there is a danger of freezing (unless Frost Protection setting is active). Check
the heater has fully drained if there is a risk of freezing. The drain valve is located at the top of
the water heater beside the cold and hot water inlet. To operate the drain valve, turn the yellow
lever clockwise 90 degrees.
If the plumbing system in the vehicle causes air locking preventing the water heater from
draining, consideration should be given to fitting a vacuum relief valve, Whale Part # AK1228.
