PROCEDURE
A. Install Cassette Awning
1. Determine location of awning.
a. Allow for a minimum of 12 mm clearance at
top and sides of awning case.
Note: Additional clearance is recommended to allow ease
of access for servicing.
b. Avoid location that interferes with entry door
swing when awning is completely extended.
Note: Awning is factory preset for a 5° fabric slope, but it
may be adjusted for a 15° slope. Allow for sufcient clear-
ance to accommodate awning pitch (slope).
For a 550 mm entry door, the approximate clearance should
be 50 mm for 5° slope, and 150 mm for 15° slope.
Make sure entry door will open without inter-
ference when awning is completely extended.
Make sure the mounting surface is at and
vertical. Any tilt in the mounting surface will
cause tilt in the lead rail. Failure to obey this
notice could result in property damage.
IMPACT OR CRUSH HAZARD. Make sure RV’s
structure will safely and securely support aw-
ning before installation. Otherwise, the cas-
sette awning may become unstable and could
bend or collapse. Failure to obey this warning
could result in death or serious injury.
FIG. 3
Mounting Bracket
RV Wall
(Solid Structure Shown)
PINCH HAZARD. Awning must be installed at
a height of more than 2.5 M above ground or
other level that could provide access to it. A
horizontal distance of at least 400 mm must
be maintained between the fully open awning
and any permanent object.
Failure to obey these cautions could result
in injury.
c. Find a solid structure in RV wall for support
of mounting bracket (if possible). See FIG. 3.
Important: A backing plate and sleeves (provided)
are needed inside RV wall to strengthen awning sup-
port. See FIG. 4.
Note: The 10.3 mm O.D. sleeves and M6 carriage bolts
provided will t up to 36 mm RV wall thickness. If RV wall
is thicker than 36 mm, longer carriage bolts and sleeves
will be required. Cut sleeves and carriage bolts (Grade 8.8
minimum) to t RV wall as necessary. Repair threads (at
cut) on carriage bolts. See FIG. 5.

8. With a mechanical lift, or the help of additional
personnel, lift the cassette awning up near the
mounting bracket.
Note: Do NOT hook onto mounting bracket until wiring is
routed.
IMPACT OR CRUSH HAZARD. Do not over-
tighten fasteners. Applying too much torque
may cause fasteners to fail, and could allow
awning to collapse. Failure to obey this warn-
ing could result in death or serious injury.
2. Using the mounting bracket as a template, mark
it’s position and all hole locations. See FIG. 3.
3. Mark a line between the (2) outside top holes,
and the (2) outside bottom holes. See FIG. 6.
6. Install mounting bracket securely with provided
backing plates, sleeves, carriage bolts, locknuts,
and washers. Tighten to 4 ±0.5 Nm torque. See
FIG. 3 and 4.
7. Apply sealant along entire top edge of mounting
bracket where it meets the RV’s wall. See FIG. 7.
LIFTING HAZARD. Use proper lifting tech-
nique and control when lifting awning. Failure
to obey this caution could result in muscle
strain, back injury, or property damage.
Before drilling, make sure there are no ob-
stacles inside RV wall (cables, wires, gas
pipes, etc.).
5. Pre-drill 12 mm clearance holes for sleeves on
the marked (intersecting) locations. See FIG. 3
and 6.
Mounting bracket must be installed on a at
surface, and leveled to ensure proper function
and appearance.
To help prevent water leakage, always use
sealant (Sikaex 252 or similar) on clean parts
and surfaces where fasteners enter RV’s side
wall or roof.
4. Verify horizontal lines are level, then mark verti-
cal lines from all remaining holes to intersect the
marked horizontal lines. See FIG. 6.
Note: Due to the nature of long extruded parts, the mount-
ing bracket may be slightly bowed. Some hole locations
may be above or below the marked horizontal lines.
