INSTALLATION INSTRUCTIONS
The toilet should be fixed to a vertical back wall. When a back wall is unavailable,
one will have to be installed (see point 6, 8, 14).
1. Take the toilet out of the box.
2. Remove plastic bag with parts out of the bowl. Included should be the
“instructions for use” and a holding tank cap.
3. Read “instructions for use” to get familiar with part names. Remove cassette
waste tank by lifting the tank locking clip at the pour-out spout (see diagram
2).
4. Remove all loose parts from toilet fluid storage compartment.
5. Remove shower tray if it will not allow fitting of toilet and modify to suit if
possible.
6. Position the toilet unit at the chosen place against outside wall and lift the
cover to check for vertical clearance. If new vertical wall needs to be erected,
put some scribe lines for the position of the back wall. Erect the rear wall
temporarily into position. Check if the wall is vertical and square with the
outside vehicle wall. Remove the toilet.
7. Position template 1 into the corner of the rear wall/outer vehicle wall and the
surface where the to ilet will stand on. In case of carpet, take compressing into
consideration (see diagram 7).
8. Drill two holes 3 mm through the vehicle wall from the inside. Positions are
indicated on template 1. Remove the template.
9. Position template 2 on the outside, using two screws in drilled holes. Outer
dimensions template 2 is for checking 20 mm (distance from trimming, body
extrusions and, or wheel arch to aperture) (see diagram 8).
10. Replace template 2 with
3
and draw a line with a felt pen around template 3
to mark the cutting line for the door frame aperture (see diagram 9).
11. Remove template 3 and put tape for protection against scratching at the end
and outside of the cutting line. Insert the jig saw blade according to diagram
10.
12. Make the cut out with a jig saw. Be sure to cut perpendicular to the outer wall
(see diagram 10).
13. Prepare 4 wooden bars to be inserted into outer wall as reinforcement for
locating outer frame.
