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 non-

conditioned 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 non-

conditioned 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.

D. Physical Installation

MINIMUM CLEARANCES

These units have a 0" minilnuln clearance to

combustible materials rating f?om all cabinet

surfaces. The unit should be installed with

selwiceability clearance of 30" f?om the fiont of the

unit. The unit can be selwiced entirely fiom the fiont,

including replacing the filter. Be sure and route

primal T and secondary drain connections so as

not to obstruct replacement of filter.

ARRANGEMENT

Unit is shipped fiom the factory arranged to be

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 have a platform

fiamed in, with an opening on top of the platform

centered in the closet. Connect the supply air outlet

to a warm air plenmn. Install return air _ifles fiom

496 01 4118 00 1 05/18/04

outside the closet to space below the platforln.

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).

1. Remove and set aside front panels.

2. Remove the coil support bracket (4

screws.

3. Remove horizontal drain pan

retaining clip (1 screw).

4. Carefully remove coil assembly and

bottom drain pan.

5. Move Horiz. Drain pan from left

hand side of coil to right.

6. Install modified coil assembly back

into unit.

7. Reinstall coil support bracket and

horizontal drain pan retaining clip.

8. Determine drain holes being used and

reposition knockout caps.

9. Reinstall doors.

CAUTION: IT IS MANDATORY TO USE AN

EMERGENCY AUXILIARY DRAIN PAN WITH

ANY COIL OR AIR HANDLER INSTALLED IN

AN ATTIC OR ABOVE A FINISHED CEILING!

F. ELECTRICAL WIRING

Refer to the unit's nameplate for specific electrical

data.

CAUTION: DISCONNECT POWER AT MAIN

FUSE OR CIRCUIT BREAKER

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 pre-

selected 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

496 01 4118 00 2 05/18/04

codes.Thisincludesthestandardsof theNational
