INSTALLATION GUIDE
2. Introduction
The AAM Series air handlers are versatile multi-positionable units.
These air handlers have the following standard features:
I. Application Versatility
Upflow or horizontal right as shipped (field-convertible for down-
flow or horizontal left applications). Can be ARI matched with most
brands of air conditioners or heat pumps for use with either R22 or
R410a when proper metering device is used.
II. Cabinet
Sturdy, galvanized steel cabinet with painted front panels. Cabinet
fully insulated with 1/2" faced insulation to prevent sweating and
mold growth, to encapsulate glass fibers, and to provide excellent R-
value. Stick pins ensure insulation remains in place. Units ship with
disposable filter in filter rack.
III. Modular Heat Kits
Heat kits available with either circuit breakers or terminal blocks.
Available from 3 to 30 KW. Models with electric heat include se-
quencers and temperature limit switches for safe, efficient operation.
Modules are easily installed in the field using molex plugs or can be
ordered factory-installed. Controls are accessible from the front for
easy service. Electrical connections can be made from the top or left.
Disconnect does not protrude through the wall panel. Fan time delay
relay standard for increased efficiency.
IV. Electronic Circuit Board
Electronic circuit board provides 30 secs ON/OFF blower time delay
extracting more heat/cool from the coil.
V. Blower
Direct drive multi-speed blowers circulate air quietly and efficiently.
3-speed motors allow for precise air volume selection. Motor speeds
can be easily selected via motor terminals. Blowers mounted on rails
so they can be easily removed for service.
VI. DX Coil
High efficiency rifled copper tubes/enhanced aluminum fins provide
maximum heat transfer. All coils immersion tested at 500 psi then ni-
trogen pressurized and factory sealed for maximum reliability. Liquid-
line Schrader allows pre-installation pressure testing. Available with
