FITTED EQUIPMENT

THETFORD CASSETTE C-402
TOILET

Preparing for use

Open the access door on the outside of your
motorhome.

Turn the water filling funnel outwards, remove
the cap and add the stated amount of
Thetford toilet fluid for the water tank. This
ensures a better and cleaner flush and keeps
the water in the flush tank fresh. After this, fill
the water tank with clean water.

Screw the cap back onto the water filling
funnel and turn it back inwards towards the
side of the flush water tank.

Note:

150 ml water remains in the water

filling funnel when the water tank is empty.

1. Remove the waste tank by pulling the

safety catch upwards.

2. Pull the waste tank outward to the stop.

Tip it slightly and take the tank fully out.

3. Place the tank upright and turn the

emptying spout upwards.

4. Remove the cap, with the measuring cup

inside, from the emptying spout and pour
the stated quantity of toilet fluid into the
waste tank. This avoids unpleasant
smells in the waste tank and keeps the
inside of the waste tank clean. Next add
approximately 2 litres of water - enough
to ensure that the bottom of the waste
tank is covered. Screw the cap back onto
the emptying spout. Turn the emptying
spout back to its original position.

WARNING:

Never add toilet fluid via the

valve blade or via the toilet bowl.

5. Slide the waste tank back into its original

position via the access door.

Note:

Never use force if you cannot get the

tank back into place easily. This may cause
serious damage.

6. Make sure that the waste tank is secured

with the safety catch. Shut the access
door and lock it.

7. Run water into the bowl by pressing the

flush knob briefly or open the valve blade
by turning the handle anti-clockwise. Your
Thetford toilet is now ready for use.

After use, open the valve blade (if still
closed) by turning the handle anti-
clockwise. Flush the toilet by pressing the
flush knob for several seconds. Close the
valve blade after use.

Note:

Do not leave water in the bowl if the

toilet is not being used. This does not help to
reduce unpleasant smells and only leads to
flooding.

Comment: To avoid blockages we advise the
use of Thetford’s fast dissolving toilet paper,
Aqua Soft.

Emptying

The waste tank has a capacity of 17 litres
and must be emptied at the latest when the
red light in the level display lights up. The
indicator lamp will light up when the waste
tank can still take about 2 litres, which is
about three uses. It is advisable to empty the
waste tank earlier.

Note:

Do not allow the waste tank to become

too full.

Make sure that the valve blade is closed.
Open the access door located outside the
vehicle. Pull the safety catch upwards
and remove the waste tank.

10. Stand the waste tank upright (Pull-out

handle at the top, wheels at the bottom).
Press the handle down and move it away
from the waste tank until it snaps out of
its locked position.

11. Pull the handle up and wheel the waste

tank to an authorised waste dump.

12. Push the handle back. Turn the emptying

spout upwards and remove the cap from
the spout. Hold the waste tank by the
upper handle with one hand, while
placing your other hand by the rear
handle so that during emptying you can
operate the vent plunger with your thumb.
To empty the tank without splashing,
depress the vent plunger while emptying
the tank. After emptying, flush the tank
thoroughly with water. Also clean the
valve blade with water.

Note:

The vent plunger should only be

pressed once the emptying spout is pointing
downwards!
