Waste Pump-Out button to pump out
the waste from the holding tank Into the
vehicle’s waste tank. The button will flash
while the waste is being pumped and will
stop automatically (after approximately
5 minutes) when all waste has been
transferred.
If the vehicle’s waste tank is full, the Waste
Pump-Out light will flash rapidly and no
pump-out will be possible until the central
tank is emptied. (Check the level of the
vehicle’s waste tank on the vehicle’s central
console).AftertheWasteHoldingTankhas
been emptied, there will be approximately 1.5
litres of waste left in the tank. This is normal.

Important! It is vital that the correct
amount of toilet fluid is added to ensure
the proper breakdown of the waste in
the holding tank. Only use the system
when the tank is full. Using the system
too often on an empty tank can cause
damage to the pump, which could cause
the system to fail.

regularly, depending on the amount of use. To
clean Thetford toilets, we advise using water
