Air Distribution System
Installation
It is the responsibility of the installer to review each RV floor
plan to determine the following items in conjunction with "Air
Distribution Duct Sizing and Design" section on Page 8.
NOTE: Alternate configurations and methods may be used
which will allow the unit to operate properly, however, these
alternate configurations and methods MUST be approved by
Furrion in writing.
• Duct size
• Duct layout
• Register size
• Register location
• Thermostat location
• Indoor temperature sensor location (if applicable)

Air Conditioner
Preparing Wire Connections
Each rooftop air conditioner opening must be prepared
with proper wiring to connect the ceiling controller of the air
conditioner to the 115VAC supply voltage.
NOTE: The wire connections need to be positioned in the
1/4
forward facing
section of the opening.
DANGER
Electrical Shock Hazard
• Disconnect power before servicing. Failure to obey this
warning could result in death or serious injury.
• Provide grounding in compliance with all applicable
electrical codes. Failure to obey this warning could result
in death or serious injury.

115VAC Supply
1. Prepare a dedicated 20 amp rated circuit for each air
conditioner unit, protected with a time delay fuse or circuit
breaker.
NOTE: With multiple air conditioners on a 50 amp service, it is
best to balance between the line voltage legs.
2. Extend circuit with a 12AWG 2-wire with ground to the roof
opening.
NOTE: The wire gauge is generally acceptable per NEC code,
refer to rooftop unit nameplate and applicable code for proper
sizing.
3. Protect the wire where it passes through any rough surfaces
or openings.
4. Terminate with at least 15" (381mm) of supply wire extending
out of the roof opening. This ensures an easy connection at the
control box.
12VDC Supply
1. Prepare a 15 amp max protected circuit to supply power to
all air conditioner units.
NOTE: The branch circuit can be dedicated or shared with
other utilization equipment.
2. Extend circuit with a 14AWG 2-wire, (12V+, 12V-) to the roof
opening.
3. Protect the wire where it passes through any rough surfaces
or openings.
4. Terminate with at least 15" (381mm) of supply wire extending
out of the roof opening. This ensures an easy connection at the
control box.
Wall Controller Connection (Single and Multizone
Thermostat)
1. Prepare 4 wires to connect between the ceiling controller
(roof opening) and wall controller/thermostat (wall opening).
NOTE: 18AWG max should be used, Furrion recommends
using a standard thermostat wire with at least 4-wires.
2. Terminate with at least 15" (381mm) of wire end for easy
connection.
3. For Multizone installations, prepare additional wiring of the
same type to connect between each roof opening.
Furnace Switch (Optional)
1. If required to operate the furnace using the air conditioner
wall controller/ thermostat, prepare 1-wire to connect the
desired ceiling controller (roof opening) to the furnace switch.
NOTE: This serves as a 12V+ line, that becomes hot only
when the ceiling controller closes the furnace switch to turn the
furnace on.
2. Terminate with at least 15" (381mm) of wire at each end for
easy connection.
