2. Assess Roof Strength
• The roof members MUST be strong enough to support the
weight of the unit without any roof defl ection that will
cause "pooling" of water around the unit. Contact your
caravan manufacturer to confi rm the max load the roof is
able to handle.
• If the roof does not have an existing hole one must be cut.
Cut through the roof then use the roof hole as a guide to
cut through the ceiling. Contact your caravan
manufacturer for the best method to cut through the roof.
• The square hole in the roof (356 x 356mm, 14" x 14") MUST
be boxed up with minimum 20mm square timber to
provide a structure strong enough to withstand the
compression of the installation bolts. This is also to ensure
that air in not drawn from the roof cavity (Fig 3 & 4).
Remember to leave access for wiring.
• Longitudinals MUST be fi xed securely to the transverse
roof members to transfer load (Fig 3 & 4).
WARNING
There may be electrical wiring located between the roof and
ceiling. Ensure that power is properly disconnected at the
supply (mains and/or battery). Failure to do so may result in
personal injury or death.
TIP: Always use crawl boards across the roof to avoid damage.
3. Installing Weather Collar
Ensure that the roof is clean, dry and free from
grease or oil and that there are no roof seams
running through the installation area.
IMPORTANT
The weather collar must be assembled to the roof
top the right way up. Check the orientation of the
part. Look for the 'THIS SIDE UP STICKER'.
• Apply silicone sealant to underside face of collar
(Fig 5 – left hand picture).
• Turn collar over, make sure 'THIS SIDE UP' sticker
is facing up and apply the collar to the 14" hole.
• Push down on collar and remove excess from
around the edges.
Longitudinals must be fi xed securely
to transverse roof members

and a 14' hole boxed.
20mm min
The roof cavity must
be framed to support
the units weight.
Fig 4: The roof cavity MUST be boxed with timber to provide a
solid structure.
Apply sealant to
this underside
face only.
Fig 5: Left hand picture shows underside of weather collar –
apply sealant across this entire face. Right hand picture shows
'THIS SIDE UP' sticker. Keep this side up when applying to roof.
Be sure to allow
space for power
cable.
