5. Frame the opening so it will not collapse when
bolting the rooftop component down.
6. At the front of the frame opening, leave or create
an access hole to allow for the length of exposed
115 VAC power supply wiring required to complete
the installation.
7. Using the roof opening as a guide, cut a matching
hole in the ceiling of the RV interior.
6 .3 Routing the Wiring
I
The power must be on an appropriately-sized
separate time-delay fuse or circuit breaker. See
“Specifications” on page 10.
This section describes how to route the wiring for the
rooftop component.
1. Position the copper 115 VAC power supply wire, with
ground, in the front portion of the roof opening.
2. Route the 115 VAC power supply wire from the
time-delay fuse or circuit breaker box to the roof
opening. Use a listed/certified non-metallic sheathed
single strand cable. See “Specifications” on
page 10.
I
If an AC or a vent fan were removed, the existing
power supply wire may be used provided it is of the
proper type, size, and location, and if it is correctly
fused.
3. Make sure that at least 15.0 in. (381 mm) of the
115 VAC power supply wire extends into the roof
opening to ensure an easy connection at the junction
box.
4. Protect the 115 VAC power supply wire where it
passes into the opening according to local and
national standards.
6 .4 Positioning the Rooftop
Component
NOTICE:
Do
not
slide the rooftop component along a
surface. Otherwise, damage to the gasket on the bottom
of the rooftop component could occur and cause a leak.
1. Remove all the contents from the carton and discard
the carton.
2. Place all the ADB kit contents in the RV. The ADB kit
contains mounting hardware for the ADB that will be
installed inside the RV.
3. Move the rooftop component to the roof.
