vent plunger while emptying the tank.
After emptying, rinse the tank and blade
thoroughly with water.
!
WARNING: Do not seriously shake the
tank or use high pressure water cleaners.
This may cause damage to the tank's
interior.
Note: The vent plunger should only be
depressed once the emptying spout is
pointing downwards. Prepare the toilet
for re-use if required. Slide the Waste
Holding Tank into the toilet and close
the access door.
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 Bathroom Cleaner.
Note: Never use bleach, vinegar or other
powerful household cleaners that contain
these substances. These may cause
permanent damage to the seals and other
toilet components.
Toilet bowl
• Squirt Thetford Bathroom Cleaner into the
toilet bowl.
• Flush the toilet bowl with water and wipe
down the rest of the toilet with a damp cloth.
• Clean seat and lid The seat and lid can easily
be removed: Lift the seat and lid assembly
and pull the round pins (inside the assembly)
outwards from the pin holes. After cleaning,
replace the seat and lid by positioning the
round pins in front of the pin holes and push
the lid and seat downwards.
• To keep your flush water fresh and to prevent
deposits from forming in your toilet bowl, add
a correct dosage of Aqua Rinse in your flush
water tank, if present, on your toilet.
Tip! For a really shining toilet, dry with a soft
dry cloth after cleaning.

Waste holding tank
To keep your Waste Holding Tank fresh and
clean, Thetford has developed a number
of different toilet fluids. Thetford toilet fluids
suppress smells, reduce formation of gas,
promote breakdown of toilet waste and
increase the life span of a mobile toilet. See
page 50 of the Thetford user manual for more
information. We advise a thorough cleaning of
the Waste Holding Tank once each season,
using Thetford's Cassette Tank Cleaner.
• Remove the removable mechanism from
the Waste Holding Tank by turning it anti-
clockwise and rinse it under a tap.
• Remove the cover plate from the Automatic
Pressure Release Vent by prising it up
using a small screwdriver. Use one hand
to push the Automatic Pressure Release
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 it 180 degrees and
remove it from below. Remove the rubber
seal underneath the float. Rinse the float
and rubber seal under a tap. Replace the
Pressure Release Vent using the same
method in reverse.
The rubber seals in the toilet (the lip seal,
the mechanism seal, the automatic pressure
release vent seal and the cap seal) should
be regularly cleaned with water and treated
with Thetford High Grade Seal Lubricant.
This will ensure that the seals remain flexible
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
or malfunction. The lip seal is a part of the
toilet that is subject to wear. Depending
upon the extent and manner of use, the
seals will become less effective and will need
replacing periodically.
