Think Ahead.
Since the inception of AAON® in 1988, we have maintained our commitment to design, develop,
manufacture, and deliver heating and cooling products to perform beyond all expectations and to
demonstrate their daily value to our customers.
AAON utilizes extensive product knowledge and state of the art manufacturing to continuously
provide practical HVAC products to the dynamic marketplace.
Our objective remains the same:
Meet the customer specific requirement
at a reasonable first cost.
AAON’s Celebrity1TM Modular Air Handler gives you near limitless capability for conquering
complex projects. Its superior modular design can be as flexible as your application is
demanding. Units can be ordered completely factory wired and assembled, ready for placement
and start-up, or as separate modules, to be manipulated and connected on site. With multiple
factory-installed conservation, air, and control options to choose from, AAON’s modular systems
fit jobs that would normally require a custom system design with intensive post-installation work.
That makes the Celebrity1TM very cost-effective, while creating happier customers for you.

Unit Orientation
A
When determining unit orientation
(or Supply Air Flow as it is
identified in the base model
number below), consider the air to
be “hitting you in the back of the
head” when you are facing the
return air end of the unit.
Figure 1.1, Unit Orientation
Left Hand Side
Supply Air
Top View
Assembled Modular
Air Handler
Right Hand Side
If you have a “Left Hand”
unit, then all connections
will be on the left hand
side of the unit. Air will
flow from right to left as
you look at the left side.
Return Air
If you have a “Right Hand”
unit, then all connections
will be on the right hand
side of the unit. Air will
flow from left to right as
you look at the right side.

General
Celebrity1TM modular air handling units are designed
as heating, cooling, or combination units for indoor
installation only. The use of refrigerant, chilled water,
electric resistance, steam, or hot water as operating
mediums will be dictated by design of the heating and
cooling coils installed in the unit. Flexible connectors
are required on all duct connections and installed to
minimize air leaks.
Certification
Cooling Models
a) Certified for use with a commercial
condensing or chilled water remote unit (with
or without compressor(s))
b) Certified for indoor installation only.
Steam or Hot Water Heat Models
a) Certified for indoor installation only.
Electric Heat Models
a) Certified as an electric warm air furnace with
or without cooling coil.
b) Certified for indoor installation only.
Codes & Ordinances
System should be sized in accordance with National
Warm Air Heating and Air Conditioning Association
Literature, or the Guide of American Society of
Heating, Refrigeration and Air Conditioning Engineers.
The installation must conform with local building
codes, or in the absence of local codes, with (United
States) “ANSI / UL 1995”, (Canada) current, C.S.A.
Standard C22.2, No. 236, Canadian Electrical Code
Part 1, and C.S.A. Standard B52 Mechanical
Refrigeration Code, and Local Plumbing or Waste
Water Codes.
It is the responsibility of the installing contractor to
comply with codes, ordinances, local and
municipal building laws, and manufacturer’s
instructions. Personal injury and/or equipmen
damage may result if proper procedures are no
followed.
WARNING
