Cleaning and maintenance
The toilet should be cleaned and maintained
regularly, depending on the amount of use. To
clean Thetford toilets, we advise using water
and Thetford Plastic Cleaner.
Note: Never use household cleaners
(bleach, solvents or other powerful cleaning
agents). These may cause permanent
damage to the seals and other toilet
components.
Toilet
• Squirt Thetford Plastic Cleaner in the toilet.
• Flush the bowl with water and wipe down
the rest of the toilet with a damp cloth.
Tip! For a really shining toilet, dry it with a soft
dry cloth after cleaning.
• Clean seat and lid. The seat and lid can
easily be removed. Lift the lid and seat
together and pull upwards. After cleaning,
replace the seat and lid by positioning the
round pins above the holes and then pushing
the lid and seat downwards.

Waste tank
We advise a thorough cleaning of the waste
tank once each season.
• Remove the mechanism from the waste tank
by turning it anti-clockwise, as shown on the
waste tank. Rinse the complete mechanism
under a tap.
• Remove the cover plate from the automatic
pressure release vent by prising it up using
a screwdriver. Use one hand to push the
automatic pressure vent open, while holding
the float of the automatic pressure release
vent on the inside of the tank with the other
hand. Push the float upwards, turn the
float half a turn and remove it from below.
Remove the rubber seal that is under the
float. Rinse the float and the rubber seal
under a tap. Replace the rubber seal and
float for the automatic pressure release vent
in the same way.
The rubber seals in the toilet(the valve blade seal,
the mechanism, seal and the automatic pressure
release vent seal and the cap seal) should be
regularly treated with Thetford High Grade Seal
Lubricant. This will ensure that the seals remain
supple and in good condition. If the toilet is not
to be used for any length of time, it is important
to treat the seals with Thetford High Grade Seal
Lubricant after cleaning.
Note: Never use Vaseline or any
vegetable oil except olive oil. These may
cause leakage.
Note: The valve blade is part of the toilet
that is subject to wear. Depending on the
extent and manner of service, after a certain
period the seal will become less effective
and must be replaced.
Winter operation
You can use you Thetford cassette toilet as
usual in cold weather, as long as the toilet is
situated in a heated location. If this is not the
case there is a risk of freezing. In that case we
advise that the toilet is drained by following the
instructions under 'Storage'.
