Make sure during assembly that the hose and pipe are routed so that no siphon
forms, otherwise condensation would collect here and block the pipe over
time.
The hose is disconnected from the cassette at a 90° angle
during emptying!
If stiffness occurs after some time when disconnecting the house coupling,
please spray these plastic parts with silicone spray – likewise the plugs.
This results in reduced wear, while retaining the smooth sliding property at the

Functional test of the ventilation system - Mandatory
Open the blade valve and hold a burning incense (joss) stick or cigarette above
it. If the smoke is drawn down into the holding tank the ventilation system is
working correctly.

Functional test - checking the connections
Open the blade valve and the ventilator should run. If it does not run check that
the 12 V caravan supply is switched on.
On a number of vehicles the toilet is connected to the water pressure pump
then switch on the water pressure pump.
If the ventilator still does not work, check the polarity as the ventilator has
reverse polarity protection and only runs with correct plus and minus
connections.
