GENERAL INFORMATION

I. PURPOSE
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).
-Roof thicknesses between 5.0–6.5 inches (125 -165mm)
require extra-long hold-down bolts Atwood PN 15086.
-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.
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.
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.
