Installation Checklist

Reference the checklist below to verify all steps required to successfully install a deluxe self-contained unit are complete. This checklist is intended to acquaint the installing personnel with what is required in the installation process. It does not replace the detailed instructions detailed in the applicable sections of this manual.

Installation procedure WARNING

Hazardous voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be

inadvertently energized. Failure to disconnect power before servicing could result in death or serious

injury.

General Unit Requirements

†Install and secure the ductwork to the unit.

†Check unit for shipping damage and material shortage. Refer to the Receiving Checklist.

Electrical Requirements

†Verify that the electrical power supply characteristics comply with the unit nameplate specifications.

†Inspect all control components; tighten any loose connections.

†Connect properly sized and protected power supply wiring to a field supplied/ installed disconnect and unit power terminal block, or to the optional unit mounted disconnect switch.

†Properly ground the unit.

Field Installed Control Wiring (Optional)

†Complete the field wiring connections.

Note: All field installed wiring must comply with NEC and applicable local codes.

Fan Discharge Conversion

Complete the steps below to convert the fan discharge from vertical to horizontal.

1.Remove all mid and top fan section panels.

2.Loosen the brackets inside the unit that clamp the mid and fan sections together.

3.Remove the control box cover and disconnect the motor power wires. Feed wires up through the unit and secure out of the way until rotation is complete.

4.Rotate the fan section to desired position.

5.Re-route the motor power wires back to the control box. Ensure all wiring is free and not routed over any sharp edges.

6.Reconnect the motor power wires per the unit wiring diagram.

7.Bolt and/or clamp all brackets back into place.

8.Replace control box cover and all exterior panels.

9.Verify the fan rotation and motor amp draw.

Plenum Installation

1.Uncrate the plenum and accessory bag.

2.Rotate the evaporator blower to the vertical discharge configuration.

3.Apply the soft gasket provided around the aluminum frame on top of the unit as shown in Figure I-IP-1.

4.Using a screwdriver, tighten the self- drilling screws as shown in Figure I-IP- 1. Be sure to tighten all screws on the rear, right, and left sides through the pilot holes on the plenum panels.

5.When installation is complete, adjust the motor pulley and the discharge grille for proper airflow.
