D. Wiring Requirements
1. 120 VAC Supply Line
Route a copper 12 AWG, with ground, 120 VAC
supply line from the time delay fuse or circuit breaker
box to the roof opening.
a. This supply line must be located in the front
portion of the 14-1/4" x 14-1/4" (±1/8") opening.
b. The power MUST be on a separate 20 Amp time
delay fuse or HACR circuit breaker.
c. Make sure that at least 15" of supply wire
extends into the roof opening. This ensures and
easy connection at the junction box.
d. Wiring must comply with all National, State and
Local Wiring Codes.
e. Use a steel sleeve and a grommet or equivalent
methods to protect the wire where it passes into
the opening.
E. Placing Air Conditioner On The Roof
This unit weighs approximately 100 pounds.
To prevent back injury, use a mechanical hoist
to place Air Conditioner on roof.
FIG. 7
Do not slide the unit. This may damage the
roof gasket attached to the bottom and may
create a leaky installation.
CAUTION
1. Remove the air conditioner from the carton and dis-
card carton. See FIG. 7.
2. Place the air conditioner on the roof.
3. Lift and place the unit over the prepared opening using
the gasket on the unit as a guide. See FIG. 8.
4. Place the 3105457 Mechanical Air Distribution Box
Kit inside the RV. This box contains mounting hard-
ware for the air conditioner and will be used inside the
RV. See FIG. 7.
This completes the outside work. Minor adjustments can
be done from the inside of the RV if required.
F. Installing The Air Conditioner
1. Remove air box and mounting hardware from carton.
The upper duct is shipped inside the lower duct
which is part of the ceiling template.
2. Check for correct alignment and adjust the unit as

bottom duct only. See FIG. 10.
c. If distance is 3"-4", install ducts as received.
