20. Waste Pump-Out System: When activating
the control panel this feature automatically
lights up. When the Waste Holding Tank
Level Indicator illuminates, press the
Waste Pump-Out button to pump out
the waste from the holding tank Into the
vehicle’s waste tank. The button will flash
while the waste is being pumped and will
stop automatically (after approximately
5 minutes) when all waste has been
transferred.
If the vehicle’s waste tank is full, the Waste
Pump-Out light will flash rapidly and no
pump-out will be possible until the central
tank is emptied. (Check the level of the
vehicle’s waste tank on the vehicle’s central
console). After the Waste Holding Tank has
been emptied, there will be approximately
1.5 litres of waste left in the tank. This is
normal. Add 2 litres of water and a correct
dosage of Thetford toilet fluids to the
Waste Holding Tank.
!
WARNING:
It is vital that the correct
amount of toilet fluid is added to ensure
the proper breakdown of the waste in the
holding tank. Only use the system when the
tank is full. Using the system too often on an
empty tank can cause damage to the pump,
which could cause the system to fail.
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 46 of the Thetford user manual for more
information (=matrix). We advise a thorough
cleaning of the Waste Holding Tank once each
season. Next to using Thetford’s Cassette
Tank Cleaner, the powerful cleaning agent for
the periodical cleaning of the Waste Holding
Tank of your toilet, we suggest the following:
• 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.
