• Add the stated dosage to the flush-water tank through the waterfill door (OS).
• Fill the flush-water tank with clean water through the waterfill door, using a jury can or hose (05).
  

 Not using Thetford products to care for your Thetford toilet could cause damage.
 Never add toilet additives directly via the valve blade or via the toilet bowl as this could damage the lip seal of the waste-holding tank Only fill the waste holding tank via the pour out spout.
 Never use force if you cannot get the waste-holding tank back into place easily. If blockage occurs. always check if the blade handle is in the closed position.

Check after storage:

• After storage. check the water installation on damages before filling the system with water again.
• After filling the system. check if flush is present and make sure there are no leakages.

Use of the toilet

 The toilet can withstand a maximum load of 120kg. Make sure you do not overload the toilet.

See the images in the fold-out cover for a visual reference.

Turning the toilet bowl:

• Close the cover and use both hands to rotate the bowl to the desired position (max. 90° clockwise and 170P counterclockwise) (06).
  
  Opening the blade:
• Open the blade by moving the blade handle from left to right (07).
  
  
• Always close the blade completely after use.
   The toilet can be used with the blade open or closed.
  Flushing the toilet:
• Make sure the blade is open.

Maintenance and cleaning

See the images in the fold-out cover for a visual reference. Also see the inside cover for an overview of the additives which need to be used.

Thetford recommends cleaning your toilet regularly to prevent limescale and ensure optimal hygiene.

• Clean the inside of the bowl with Thetford Toilet Bowl Cleaner and a soft brush.
• Clean the outside of the bowl with Thetford Bathroom Cleaner.
• Remove the seat and cover to clean your toilet thoroughly. To do this, push the seat and cover together to the right, then lift them up.
• Remove the float from the waste-holding tank and rinse it with tap water (04).
   Never use household cleaners to clean your toilet. These may cause permanent damage to the seals and other toilet components. For example, the use of liquid bleach could lead to discoloration.
  Thetford recommends maintaining your toilet regularly to prolong the lifespan of your toilet:
• Use Thetford Cassette Tank Cleaner 2 to 3 times a year on the waste-holding tank to remove stubborn limescale on the inside of the tank.
• Use Thetford Seal Lubricant to keep the seals soft and pliable. It has been specially developed for mobile toilets and is absolutely safe to use.
   Never use Vaseline or vegetable oil to lubricate the seals. This may cause leakage to your waste-holding tank.
   The blade seal is a part of the toilet that is subject to wear. Depending on the extent and manner of servicing, after a certain period the seal will lose quality and must be replaced.

Installing vents

The refrigerator performance depends on good ventilation through two vents in the wall of the vehicle. Cold air comes in through the lower vent, passes the cooling unit and leaves hot through the upper vent.
Use the proper vents for your refrigerator model. The correct measurements are shown in Table.
Table 7: Vent size.

You can buy vents at an authorized local Service Centre. For further instructions, see the installation instructions of the vents.
The recommended installation is when the vents are not covered.

• Make sure that combustion gases can not enter the living area.
• When the installation is next to the caravan door, make sure that there will be at least a 25mm distance between the vents and the door.

1.  Min. 25mm

Make sure vents cannot be blocked by the door or other objects. An insufficient air supply can result in incomplete combustion, the forming of carbon monoxide, and a reduction of cooling performance.

• Install the upper vent in the wall of the vehicle at the top of the refrigerator.

1. Vent size 186 x 483mm: Min. 110mm
   Vent size 257 x 432mm: Min. 135mm
   Vent size 281 x 523mm: Min. 175mm

• Install the lower vent in the wall of the vehicle on the floor level behind the power board.

If the lower vent is not on floor level, make sure all unburned gas will go to the outside (for example via a hole in the floor).
This vent is also used for periodical maintenance or repairs of the refrigerator.
