Making a new opening
1. Select an area on the roof between two longi-
tudinal supports.
2. Mark the position and size of the opening.
A 290 x 290 mm opening is recommended
but can be as large as 400 x 400 mm.
3. Drill out the corners ( A ).
4. Carefully cut out the opening on the roof using
a jigsaw or a similar tool ( B ).
5. Ensure that no electrical power cables are
damaged.
6. Before installation, check whether the roof
hole needs reinforcing.
7. Use battens to create a frame around the cut-
out made in the roof.
8. If needed, remove the insulation foam accord-
ing to the width of your reinforcing battens.
9. Fit the reinforcing battens.
Installing in an existing opening
1. Use a clean, dry cloth to wipe around the
underside perimeter of the top roof flange to
remove any dust or residues.
2. Remove the backing paper of the self adhesive
foam seal and fit onto the bottom surface of
the top roof flange. There is a slight recess on
the outer perimeter for the foam to be located.
The foam seal will easily stretch to bend
around the corners while staying flat.
3. Ensure that the arrows on the top surface are
pointing to the front of the caravan.
4. Position the top roof flange centrally within the
opening and mark the two rear corners on the
roof.
