Caravan Equipment
Cassette toilet: Use Thetford Bathroom cleaner or diluted washing-up liquid to clean the bowl, seat
and cover and the outside of the toilet. When the toilet is not going to be used for a long time, leave the
cap off the pour-out spout and leave the blade open so the cassette can dry.
▲ Never use washing-up liquids which contain chlorine, solvents or other aggressive
substances to clean the toilet.
4.14.5 Winterising / Storage
The Thetford Cassette is easily winterised for storage.
Empty as much flush water as possible by using the flush handle to empty the water into the waste
tank.
Once the pump has been cleared of water place appropriate size container under the drain plug. Empty
any remaining water from the fresh water tank by taking out the drain plug (fig. 15). Empty the holding
tank and clean the unit as described above. Clean the seals and lubricate them where appropriate after
drying. (See cleaning and maintenance).
4.14.6 Cold weather use
The toilet can be used in cold weather conditions provided that the toilet is in heated surroundings.
When the vehicle is not heated for more than a day or night, winterise the cassette.
4.14.7 High altitude and hot weather use
Pressure may build up in the holding tank if the tank is not inserted while driving at high altitudes or in
warm weather conditions. The automatic holding tank vent will vent the tank when there is over or
under pressure.
4.15 OMNIVENT ROOFLIGHT MOUNTED EXTRACTION FAN
4.15.1 Use Ventilator (only for OMNIVENT 12V)
The ventilator is started by the red switch; or “blowing” or “suction”.
The airflow is adjusted by the black switch:
position 1 = 7m3/min. (245 cft/min.) (15W - 1.2 A)
position 2 = 12m3/min. (420 cft/min.) (30W - 2.5 A)
position 3 = 20m3/min. (700 cft/min.) (50W - 4 A)
▲ Allow motor to stop completely before reversing the fan direction as this may overload the
12V supply.
