WARNING
Failure to carefully read and follow all instructions inthis manual can result in malfunction, propertydamage, personal injury, and/or death.
Shut OFF electric power at unit disconnect and/orservice panel before beginning the following proce-dures.
The information contained in this manual is intendedfor use by a qualified service technician familiar withsafety procedures and equipped with the proper toolsand test instruments.
Installation or repairs made by unqualified personscan result in hazards to you and others. Installationmust conform with local building codes or, in theabsence of local codes, with National Electrical CodeANSI/NFPA 70--1996 or current edition.
NOTE: Supply voltage, amperage, fuse and disconnect switchsizes MUST conform with all technical specifications in thismanual and on the unit rating plate.
Adapter and filler plates are shipped with the indoor units to beused with electric heat as needed depending on unit size andheater size.Theymaybe installed in theunit or supplied loose inabag.
1. Shut OFF electric power at unit disconnect switch or ser-vice panel.
2. Remove the front panel from unit and locate adapter andfiller plates,with screws insidepackageor theymaybepre-installed.
3. Attach or remove adapter plate and filler plate to heater asrequired to match the opening in the cabinet. Refer to Fig-ure 1 and table to determine what is needed for differentheater sizes.

WiringAll line voltage connections and ground connections MUST bemade with copper wire.
Thepower supplywiringMUSThaveovercurrent protection.Thiscan be either fuses or circuit breakers. Themaximumsize for theovercurrent protection is shown in the column labeled �Max.Fuseor NEC HACRBreaker (Amps)� in the Electrical Data Table or onthe unit rating plate.
Connect supply voltage wires to theCircuit Breakers on the heat-er or to the pigtails on the heater. Power for the blower motor issupplied through the connector from the heater to the controlboard.
GroundingPermanently ground the electric heat accessory in accordancewith local codes andordinances and in theUnitedStateswithNa-tional Electrical Code ANSI/NFPA70--1996 or current edition.Use a copper conductor of the appropriate size from the electricheat accessory ground lug, to a grounding lug on the circuitbreaker panel. On models with more than one circuit, a separatecopper ground wire MUST be connected for each circuit.
Adjusting Thermostat AnticipatorSet the heat anticipator of the thermostat to the proper value. Seeinstructions provided with the thermostat before making this ad-justment.

StagingThe heater elements are turned on in increments. Refer to Stag-ing Table. In addition on heaters larger than 5KW, the heat can bestaged (1st&2nd)either throughan indoor thermostat or byusingan outdoor thermostat. This satisfies staging requirements im-posedby someelectric utilities on heaters larger than 6kilowatts.
A control signal (24V) fromW1 on the Indoor T�stat to W1 on thecontrol board energizes the 1st stage of heat. A control signal(24V) to W2 on the control board energizes the second stage ofelectric heat. To turn ON both stages at the same time, using onecontrol signal, W1 and W2 are jumpered together.
If the indoor thermostatdoesnothavestagingcapabilities,acces-sory electronic outdoor thermostats are available that will controltwo stages of electric heat.
Temperature Rise CheckTemperature rise is the difference between the supply and returnair temperatures.
NOTE: The temperature rise can be adjusted by changing theheating speed tap at the unit�s blower terminal block. Refer to theunit�s Installation Instructions for airflow information.
A temperature rise greater than 60�F (33.3�C) is not recom-mended.
1. To check the temperature rise through the unit, place ther-mometers in the supply and return air ducts as close to theunit as possible.
2. Open ALL registers and duct dampers.3. Set thermostat Heat--Cool selector to HEAT.4. Set the thermostat temperature setting as high as it will go.5. Turn electric power ON.6. Operate unit AT LEAST 5 minutes, then check tempera-
ture rise.NOTE: The maximum outlet air temperature for all models is200�F (93.3�C).
7. Set thermostat to normal temperature setting.8. Turn electric power OFF.9. Be sure to seal all holes in ducts if any were created during
this process.
