I. PURPOSE
SERVICE CALLS & QUESTIONS
Location and phone numbers of qualified Service Centers can
be found at our website http:/www.atwoodmobile.com or call
866-869-3116 to locate a Service Center.
This Atwood AirCommand air conditioning unit is designed
for installation on the roof of a recreational vehicle to
provide cooling with AC1361 models and cooling/heating
with AC1511 models.
-The roof must be capable of supporting the weight of the
unit which is 86lbs (39Kg).
-The absolute minimum thickness of the roof must not be
less than 1 inch (25mm).
-The maximum thickness of the roof must not exceed
5 inches (125mm).
-Trimming of the ductwork and/or bolts may be necessary
depending on the roof thickness
It is important that the unit is installed properly and
according to the recommended guidelines.
WARNING: It is important that this installation
manual is read and understood before
installation. The unit must be installed by a
qualified service technician. Failure to properly
install the unit or attempting to modify it in any
way can be extremely hazardous and may
result in property damage and personal injury
and will void the warranty.
II. ENSURING EFFECTIVE OPERATION
The effectiveness of the air conditioner is dependent on
several factors e.g. size and heat load of the vehicle. When
an Atwood unit is installed Atwood assumes that the
vehicle is well insulated with 1 inch (25mm) foam minimum
in all walls and roof, that the windows are of moderate size
(preferably double glazed) and the roof vents are airtight
when closed. Other methods of reducing heat load include:
-Closing all doors, hatches, windows and blinds
-Position the vehicle so if porch is used, it will face the sun
and protect the windows from direct radiation.
-Turning off appliances that might increase the heat load
-Ensuring the vehicle is parked in a shaded position.
In periods of extreme high temperature it is recommended
to start the air conditioner earlier in the morning to greatly
improve its ability to cope with the expected high heat load.
BEFORE INSTALLATION
Ensure that the installation instructions have been
properly read and understood.
Installation must conform to Local wiring codes and
regulations or, in the absence of local codes, the
Standard on Recreational Vehicles, NFPA 1192. and
National Electrical Code NFPA 70.
DO NOT attempt to modify or add components to the
installation procedure.
This equipment must only be serviced by a licensed
refrigeration mechanic to maintain warranty
coverage.
If your installation varies from the method outlined
please contact Atwood Mobile Products, LLC for specialty
advice.
III. CONDENSATION
In areas of high humidity, the humid air within the RV will
cause “sweating” or condensation in parts of the unit as the
humid warm air contacts the colder air discharge system. If
this occurs please ensure the following:
-Closing all doors, hatches, windows and blinds to limit the
ingress of warm humid air
- Avoid running the inside fan on LOW or AUTO in such
conditions. Running the fan on HI fan speed will result in
higher airflow and reduce the tendency to have
condensation form.
Atwood will not be held responsible for problems
relating to incorrect or improper installation
methods.

INSTALLATION POSITION
Minimum 1 inch clearance from
side grills to any obstruction.
Minimum 8 inch clearance from
rear grills to any vertical face.
Minimum 4 inch clearance to any
45 degree face.
Unit Installation
Before beginning, mark out the position of the unit
considering the following important requirements:
- The air conditioner should be situated as centrally as
possible on the vehicle, to ensure even air distribution.
- The front of the unit MUST face the direction of
travel; failure to follow this instruction will result in
damage to the condenser fans.
- If the vehicle is over 23’ in length, or has an unusually
high heat load (see General Operating Information
section regarding expectations about insulation etc.),
Atwood would recommend 2 or more units to cool
effectively.
- When considering the installation position remember
to check for clearance around the plenum inside the
vehicle.
- Avoid an installation position where a bulkhead,
cupboard or light fitting could interfere with the
discharge air flow from the plenum.
- Contact Atwood if your installation differs significantly.
ASSESS ROOF STRENGTH
- The roof members MUST be strong enough to
support the weight of the unit 86 lbs (39kg) without any roof deflection
that will cause “pooling” of water around the unit. Contact your RV
manufacturer to confirm the max load the roof is able to handle. If in any
doubt consider the use of an external “H” frame.
- If the roof does not have an existing hole one must be cut. Cut from the
roof then use the roof hole as a guide to cut through the ceiling. Contact
your RV manufacturer for the best method to cut through the roof.
- The square hole in the roof (14” x 14”) MUST be boxed up with
minimum 3/4 inch square timber to provide a structure strong enough to
withstand the compression of the installation bolts. This is also to ensure
that air is not drawn from the roof cavity (Fig 3 & 4). Remember to leave
access for wiring.
- Longitudinals MUST be fixed securely to the transverse roof members
to transfer load (see Fig 3).
CAUTION
It is important that the unit is never more
than 5⁰ from the horizontal and the rear of
the unit should never be higher than the
front.

WARNING
The unit weights approximately 86 lbs (39kg).
Ensure a two person lift or use a mechanical
hoist to avoid the risk of injury.
-Do NOT slide the unit on the roof. This may
damage the gasket and result in leaks.
- Position the unit so that the four M8
mounting holes will line up with the four
corners of the square roof hole (Fig 7).
WARNING
There may be electrical wiring located between
the roof and ceiling. Ensure that power is
properly disconnected at the supply (mains
and/or battery). Failure to do so may result in
personal injury or death
TIP: Always use crawl boards across the roof to avoid
damage
Fig 7- Shows the view from under the roof.
POSITION UNIT ON ROOF
- Remove the air conditioner from the carton.
- Position the unit over the gasket so that the corners of
the square hole in the RV roof line up with the corners
of the square hole underneath
the air conditioner (Fig 6).
TIP: Have one person inside the RV looking through the
hole while the other is on the roof adjusting the position
of the unit.

COC-1 Installation Procedure:
1. Carefully strip and prepare the wires to the configuration as shown in Figure 1 using helpful
hints shown in photographs of Figure 2.
2. Hold the clear strain relief cover with bottom facing upward as shown in Figure 3.
3. Lay wire into locator slots, making sure the black wire is placed into the polarization slot as
shown in Figure 3.
4. Press the cable sheath into the integral strain relief slot as shown in Figure 3. Trimming of
ground wire and possibly others will be necessary. Wires must not extend beyond the
locators as shown in Figure 4!
5. While holding the strain relief cover, position the housing’s hinge posts into the hinge slots
and press down until both lock into place as shown in Figure 4.
6. Close the strain relief cover and housing by hand. Place the connector assembly into Molex
tool (preferred) as shown in Figure 5. Squeeze the tool until the connector bottoms out and
the locking latches engage on both sides. OR alternately, squeeze the top and bottom
closed with tongue and groove pliers as shown in Figure 5.1. Pliers must be a minimum of
10" long. Squeeze firmly on both sides, squarely across the connector between ribs A and B
to ensure wires seat completely into slots.
7. Inspect the connector to ensure the wires have been properly engaged into the housing
assembly contacts. A properly terminated wire is fully seated into its proper slots with no
significant bow of the cover. If the wires extend past the insulations tops, the wires must be
re-terminated with a NEW CONNECTOR. Once the cover has been closed the connector
cannot be re-used. Failure to comply with this procedure may result in the failure of the
connector.
8. Mating and un-mating the completed connector is illustrated in Figure 6.

Installation procedure for Ducted Models
1. Before installing the rooftop unit, be sure that the communication cable (supplied by Atwood) is installed
between the wall mounted thermostat location and the rooftop unit.
2. Remove self-adhesive backing from roof sealing gasket (11) and place around mounting hole. Apply a modest
amount of silicone sealant around the perimeter of the gasket. Position Cormorant air conditioner (1) over
14inch square hole. Front of air conditioner must face direction of travel.
3. Connect supply power to unit.
4. Connect control cable plug coming from unit to the control cable extension. Plug other end of control cable
extension into the control key pad at the remote location.
5. Cut polystyrene baffle (2) so that it is the same height as the distance from the ceiling to the steel base of the
air conditioner.
Note: The baffle has three sides covered with a self-adhesive foam strip. Cut height from the side without foam strip.
Baffle height = ceiling to base height
6. Once cut to height insert the baffle into the slot in the plenum deck assembly (3)

minute delay before the compressor starts.
MAINTENANCE
I. Plenum Filters
The plenum filters are the only parts that require routine maintenance. They
must be cleaned periodically to ensure that they do not become clogged with
dust and other particles and not covered by Warranty.
To clean the two plenum filters, first remove them both from the plenum by
pulling them out of the assembly.
The state of the filters can be ascertained from its appearance, the filters are
translucent, and if they appear clogged then they should be cleaned. Generally
the filters can be cleaned sufficiently by tapping them together to shake loose
the dust and particles trapped inside.
WARNING
Airborne particles can pose a health risk, particularly to young
children and the elderly. Ensure that filters are cleaned in a safe and
well-ventilated area.
If a more thorough cleaning is required then the filters can be washed out
using warm soapy water. Care must be taken to avoid ripping the fabric.
The filters should be cleaned every two weeks or more when in use. Prolonged
use, higher concentrations of airborne particles, and various other factors may
result in the filters needing to be cleaned more often.
Replacement filters can be ordered directly from Atwood Mobile Products, LLC by calling 866-869-3118.
II. Mounting Bolts
Atwood suggests that the hold down bolts are initially checked for tightness
within the first 3 months of installation, and thereafter every 12 months if the
vehicle is in constant use.
III. Storage
The air conditioner should be run on a routine basis to ensure the components
remain in working order.
If the vehicle is in storage or is to remain unoccupied for an extended length of
time it is recommended than the air conditioner is allowed to run
uninterrupted for 20-30min once every six months.
