AIR

INSTALLATION
INSTRUCTIONS
ELECTRIC FURNACES / AIR HANDLERS
AHX SERIES
A. Introduction
These Air Handlers come in a variety of models and
sizes for upflow, or horizontal use and come l?om the
factory with cooling coils and a horizontal drain pan
already supplied for air conditioning and heat pmnp
applications.
These instructions are primarily to assist qualified
individuals trained and experienced in the proper
installation of this type of equipment.
Refer to
authorities
having
jurisdiction
for
additional
guidance. Remember that the Clean Air Act of 1990
requires
technician
certification
l\_r handling
rel?igerant.
B. Rules for Safe Installation and Operation
1. Read these rules and the instructions carefully.
Failure to lbllow the roles and the instructions could
cause a malfunction of the unit, and a possible safety
hazard. Keep these instructions nearby the unit for
future reference.
2. While this unit has been designed and
manufactured to comply with National Codes, it is the
instafler's responsibility to install this unit to comply
with National Codes and/or prevailing local codes
and regulations. The manufacturer assmnes no
responsibility for units installed in violation of any
code or regulation.
3. Before
selaTicing, allow unit to cool.
ALWAYS SHUT OFF ELECTRICITY
WHEN
WORKING
ON UNIT. This will prevent any
electrical shocks or burns.
4. Ground the unit to prevent electric shock. All
electrical wiring should be in accordance with the
National Electrical Code.
5. Duct work must be installed in accordance with
the standards of the National Fire Protection
Association (NFPA) for the installation of Air
Conditioning, Warm Air Heating and Ventilating
Systems (NFPA 90A and 90B). The air distribution
duct system should be sized for 0.2 inches of static
pressure.
See National
Environlnental
Systems
Contractors Association Manual K for duct sizing
recolrnnendations.
Duct_xs_rk in non-conditioned
spaces must be insulated to prevent forlnation of
condensate and for maximum operating efficiency.
6. The safety testing agency label appearing on
these units covers the unit and factory installed coil
(if provided) only. It does not cover any other
equipment.
7. Exterior surface of cabinet may sweat when unit
is installed in non-conditioned space such as attic or
garage. Installer must provide protection such as full
size auxiliary drain pan on all units installed in non-

conditioned space such as attic or garage type
installations to prevent damage fiom condensation
runoff. It is recolrnnended that units installed in nonconditioned
space be insulated with 1" thick
fiberglass with the vapor barrier on the outside.
8. While designed to operate quietly when
properly installed, several steps should be taken to
insure this. Use of isolation pads when mounting
unit, flexible duct collars for discharge, and use of
acoustical duct liners are all good installation
practices that promote quiet operation.
9. Cabinet insulation is rated for R 4.2 (standard).
Nameplate on unit shows what is installed. Some
jurisdictions require R 6.0 on installations in nonconditioned space. Add insulation 1" thick to exterior
of furnace to comply in these jurisdictions, putting the
vapor barrier on the outside.
C. Unpackin_
the Unit
The unit should be unpacked
on receipt
and if
damage
is found,
a claim
should
be made
ilrnnediately
by the receiver to the shipping carrier.
Your electric air handler is completely
asselnbled.
Only
electric
power,
thermostat
wiring,
duct
connections,
refiigerant
and drain connections
are
needed for installation.
Check the rating plate for
unit size, voltage, phase etc. to make sure unit meets
your requirelnents.

installed in a vertical upflow or horizontal right to left
airflow position (standard)
or field convertible
to a
horizontal left to right airflow position.
Upflow Application
In an upflow installation
the discharge
outlet is at
the top. Care should be taken to insure unit is level to
permit proper condensate
drainage.
Normal upflow
installation
will be in a basement
or closet.
If
installed in a closet, the closet should
fiamed in, with an opening on top
centered in the closet.

Platform must be at least 10" above the floor. If
installed in a basement, run supply and return
ductwork in accordance with local codes.
Caution!! A "P" trap must be installed in the coil
drain line! Cap unused drain fittings.
Horizontal application
Horizontal application will normally be used in an
attic or crawl space. This type installation requires a
return air duct be attached to the furnace inlet. The
opposite end of the return air duct is attached to a
return air filter grill through the ceiling or wall.
Remove filter from unit if filter grill is used. The unit
is shipped in right to left confimlration. For left to
right applications (Before connecting drains and
refi'igerant lines).

F. ELECTRICAL WIRING
Refer to the unit's nameplate for specific electrical
data.
CAUTION:
DISCONNECT POWER AT MAIN
FUSE
OR
CIRCUIT

DISTRIBUTION
PANEL BEFORE WIRING
FURNACE TO PREVENT SHOCK OR FIRE
HAZARD.
POWER WIRING
Unit is suitable for use with copper conductors.
Tighten all wire connectors. Take care not to damage
heater ceramic insulators. For correct field wire size,
see unit nameplate and field wiring table inside
electrical compartlnent door. Use 75 degrees C
minimum wire in unit wiring compartlnent. Units
larger than 10KW will require multiple sets of power
conductors.
NOTE: SEE UNIT FOR COMPLETE WIRING
DIAGRAM
LOCATED
ON
BLOWER
HOUSING.

CONTROL WIRING
Field connections are made to the low voltage
terminal strip.
Consult installation instructions
provided
with
accessory
items for
specific
inforlnation
on control wiring. Use 18 AWG
minimum copper control conductors or control wiring
up to 50' between units. 16 AWG control conductors
are recolrnnended for lengths between 50' and 100'.
Class 2 wiring is acceptable. Take care not to short
control leads, transforlner burn-out could result. Set
therlnostat heat anticipator at 0.15 amps for furnaces
12KW or smaller, set at .3 for 15KW and larger. See
heat pump installation instructions for correct wiring.
BLOWER MOTOR
Units are equipped with a three speed blower motor.
Two factory selected motor speed leads are connected
to the blower relay to provide automatic speed change
for heating and cooling airflow volmnes. The preselected motor speeds would normally not have to be
changed in the field. All models contain a blower
time delay relay (TDR 10-30 seconds) that delays the
blower turning on and off when the therlnostat calls
for "Fan Only" or Cooling.
The TDR improves
ener_w efficiency.
G. REFRIGERANT
COIL
To make sure the coil in the air handler you have
received has the correct flow device for the
condensing unit you are matching it with refer to
Table B on the following pages.
H. REFRIGERANT
PIPING
Air handlers with cooling coils require liquid and
suction piping sized in accordance with condensing
unit recomlnendations.
Refrigerant lines should be
soldered with silver solder or other high temperature
brazing alloy. The manufacturer recommends that
dry nitrogen be flowed through the refiigerant lines
during the brazing operation. Liquid line is capped.
Copper stub is shipped in the electrical control box or
taped to the blower door.
I. CONDENSATE DRAIN
The air handler A coil drain pan has two _A"NPT
felnale primary and two secondary connections (left
or right hand). Horizontal pan has two 3/£, NPT
felnale, one primary and one secondary. Piping tiom
each fitting used is to have a 172" lninimuln trap and
each run in such a manner as to provide enough slope
for adequate drainage to a visible area. Do not pipe
these two fittings together into a colmnon drain. Cap
unused connection.
a. AIR FILTER
Air handlers are factory equipped with an air filter
If the return grille has its own filter relnove filter
installed in the air handler.
K. DUCT WORK
Ductwork should be fabricated and installed in
accordance with all applicable local and/or national
