The Thetford Cassette Toilet is a high quality product. The
toilet forms an integral part of your caravan or camper
bathroom, thanks to its functional design which combines
modern styling and ease of use. The C-250 Cassette Toilet
is manufactured from high quality synthetic materials which
makes it a durable, user and maintenance friendly toilet.
The toilet is made up of two parts: a permanently xed part
and a waste-holding tank that is accessible from the outside.
The removable waste-holding tank is located under the
toilet bowl and can be removed via a door on the outside of
the caravan or camper. The Thetford Cassette Toilet is the
solution to the sanitary problem in your caravan or camper!

catch (which holds the tank in place) upwards.
3. Pull the waste-holding tank outward. Tip it slightly and
take the tank fully out.
4. Place the tank upright and turn the rotating emptying
spout upwards.
5. Remove the cap, with the measuring cup inside, from
the emptying spout and pour the correct dosage of
Thetford toilet uid (see product label) into the waste-
holding tank. This avoids unpleasant smells and keeps
the inside of the tank clean. Next add approximately 2
litres of water - enough to ensure that the bottom of the
waste-holding tank is covered. For more information on
Thetford toilet uids, see last page of this manual. Screw
the cap back onto the emptying spout and turn back to
its original position.
The emptying spout measuring cap is supplied in
the same packaging as this manual.
Never add toilet uid directly via the blade
or the toilet bowl as this could damage the lip seal of
the waste-holding tank. Always pour the uids via the
emptying spout.
6. Slide the waste-holding tank back into its original
position via the access door.
Make sure that it is secured with the safety catch. Close
the access door and lock it. Your Thetford toilet is now
ready to use.
Never use force if you cannot get the tank
back into place easily. This may cause serious damage.
If blockage occurs, always check if the blade handle is in
the correct (closed) position.
7. For toilets with own ush-water tank: Open the water
lling door and ll the ush-water tank with the correct

litres) using a jerry can or hose. Close the door and lock
it. Your toilet is now ready to use.
Use fresh (tap) water for the water tank.

of your caravan and remove the waste-holding tank (as
described above).
