Installation requirements

The electric heat option consists of a single stage heater and is used in IntelliPak units or units with a field- installed thermostat. The electric heater ships separate for field installation and wiring. Available heater kW per unit size is listed inTable I-PR-2. Electric heat can be installed on units with a vertical discharge. However, it cannot be installed on units with plenums. See Figure I-PR-12 andTable I-PR-3 for electric heat dimen- sional data.

Table I-PR-2.Available Electric Heat kW

Unit Size	Heater kW
20 Tons	16
25 Tons	20
30 Tons	24
32 Tons	26
35 Tons	28

Installation Procedure

1.Remove the fan discharge shipping covers, if they have not already been removed.

2.Install the open-cell gasket around the discharge opening on the heater.

3.Position the electric heater so that the unit fan discharge openings line up with the electric heater openings. For a

vertical discharge unit, position the electric heater as shown in Figure I-PR- 12.

4.Use the hole pattern in the electric heat as a template for marking and drilling 3/16” diameter holes in the unit.

5.Bolt the electric heaters to the unit using 1/4” sheetmetal screws.

Note: It is very important that electric heaters are selected based on unit voltage and tonnage because discharge opening sizes vary by unit tonnage.

NOTICE

Use Copper Conductors Only!

Unit terminals are not designed to accept other type conductors. Failure to use copper conductors may result in equipment damage.

WARNING

HazardousVoltage w/Capacitors!

Disconnect all electric power, including remote disconnects before servicing.

Follow proper lockout/tagout proce- dures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided byTrane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors.Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

Note: For additional information regard- ing the safe discharge of capacitors, see PROD-SVB06A-EN or PROD-SVB06A-FR.

1.Before wiring the electric heater, remove the unit wiring diagram from the unit control panel and refer to the connection points.
