5.5 Kitchen area
When the sink is not in use, close the drain with the drain plug to counteract moisture in the motorho-
me and deformation of the covers.
5.6 Holding tank with Thetford C-250 Pump-out toilet (= option)
Motorhomes with a holding tank offer you the opportunity to pump the contents
of the THETFORD cassette into the 80 l holding tank. This is emptied via a slide A
using a flexible hose.
Subsequently, each time the tank is emptied, a water hose should be connected to
the Gardena adapter B on the tank and the tank should be thoroughly rinsed out
from the inside using the built-in flushing line.
Emptying waste holding tank:
• Guide the waste hose (C) of the holding tank over the chute to the
disposal station.
• Opening the waste tank slider (A)
• Empty the waste holding tank completely
• Coupling the flushing hose (B) to the outside water network
• Turn on the tap and rinse for 2-4 minutes
• Turn off the tap
• Close the waste holding tank
• Disconnect the flushing hose from the external water network
• Place the drain hose back on the slide
The waste holding tank should be emptied and rinsed thoroughly after each trip. Especially when decommissioning over
the winter months, make sure that the tank has been completely emptied. The rubber seals of the entire system have
to be maintained regularly. We recommend treatment with THETFORD care spray

Please only empty at disposal stations. The use of sanitary additives is mandatory. We recommend
“Aqua-Chem blue/green” from THETFORD. Only use easily decomposable toilet paper. Ordinary house-
hold toilet paper is not suitable. We recommend “Aqua-Soft” from THETFORD.
