10. Slide the waste tank back into its original position via the access door. It should easily
slide back into place. Do not use excessive force as this may cause considerable
damage.
11. Make sure that the waste tank is secured with the safety catch. Shut the access door
and lock it.
12. 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.
13. 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. TIP: The flush of your
toilet will be more effective if you pulsate the flush by pressing the flush button several
times in a row. 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.
NOTE: To prevent clogging, Thetford recommends using Aqua Soft, Thetford’s quickly
dissolving toilet paper.
WARNING: Please do not travel with a flush water tank that is too full (we advise empty, but
definitely not filled more than half full). Do not travel with water in the toilet bowl. Failure to
adhere to this notice may result in water damage to your caravan. Please avoid travelling with
a waste holding tank that is more than ¾ full. This may cause leakage through the venting
system.
The waste tank has a capacity of 19 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 3 uses. It is advisable to empty the waste tank earlier. Do not
allow the waste tank to become too full.
