INSTALLATION INSTRUCTIONS
In a travel trailer installation, if within a
cabinet or in the ceiling, ducting may be
required.
5. Interior access openings should be prepared as
shown. Cabinet front opening must be 20″ wide
by 14″ high to provide an opening for the dis
-
charge and return air grille. The opening must
be 1″ above the mounting surface of the unit. A
discharge and return air grille with register op-
tion is available to speed up the installation. An
electrical service opening is provided by remov-
ing the return air grille. See (FIG. 2).
D. Wiring Requirements
1. Route a copper, with ground, 120 Vac 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
“A. Table - Unit Data” on page (5).
2. Make sure enough supply wire extends into the
compartment to ensure and easy connection at
the junction box.
3. Protect the wire where it passes into the com-
partment with approved method.
4. Route a dedicated 12 Vdc supply wire (18-
22 AWG) from the RV converter (filtered side)
or battery to the unit compartment. Make sure
enough supply wire extends into the compart-
ment to ensure an easy connection at the unit.
5. Route a 3 conductor cable from the compart-
ment to the Liquid Crystal Display Single Zone
(hereinafter referred to as LCD SZ) thermostat
mounting location. Make sure enough wire ex-
tends into the compartment and 6″ extends from
the wall at the thermostat mounting location.
See “E. Choosing Thermostat Location” on page
(7).
6. If system includes a gas furnace, route two 18
gauge thermostat wires from the furnace to the
unit compartment. Make sure enough wire ex-
tends into the compartment to ensure an easy
connection at the unit.
E. Choosing Thermostat Location
The proper location of the thermostat is very im-
portant to ensure that it will provide a comfortable
RV temperature. Observe the following rules when
selecting a location:
1.
Locate the thermostat 54″ above the floor.
2. Install the thermostat on a partition, not on an
outside wall.
3.
NEVER
expose it to direct heat from lamps, sun
or other heat producing items.
4. Avoid locations close to doors that lead outside,
windows or adjoining outside walls.
5. Avoid locations close to supply registers and the
air from them.
F. Installing Unit
Hold-down clamps, screws, drain fitting, and
sealant used in step 1 & 2 are in hardware kit
3107662.003 and is purchased separately.
1.
Now that your compartment is ready with all
holes cut, carefully slide the unit into position
from the outside. Clip the hold-down clamps
over the base pan flange and secure in place
with screws. See (FIG. 5).

Next, install the drain fittings in the base pan.
Sealant must be added around the threaded end
of drain fitting before it is screwed into the base
pan. See (FIG. 5).
3. Install the rain shield. See (FIG. 9).
The rain shield
MUST
have sealant ap-
plied to the short flange surfaces and bot
-
tom of the unit, sealing the compartment
from rainwater and condensation.
4. Seal along the unit bottom to rain shield.
5.
Using 1/2″ plastic tube, (installer supplied) ex
-
tend the drain fittings through the vent grille or
through holes in the bottom of the compartment.
Make sure to seal around the tubing where it ex-
its the bottom of the compartment, and that the
condensate will drain to the outside of RV.
6.
Make sure the condenser deflector is against
the back of the outside grille. This will decrease
recirculation of hot air back into the grille. Install
the outside grille. See (FIG. 5) & (FIG. 9).
7. The outside work is complete.
