Installation Procedure

Installation Checklist

The checklist listed below is a summary of the steps required to successfully install an integral air-cooled unit. 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.

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

Refer to Figure I-IP-1 andTable I-IP-1 while following the steps below to convert the fan discharge from vertical to horizontal.

1.Remove the front and top fan section panels.

2.Loosen the fan motor to release belt tension. Remove the fan belt. Do not force the belt over sheaves.

3.Remove the bolts holding the fan scroll to support channels. Lift fan out through the front of the unit.

4.Move the fan sheave to the opposite

end of the fan shaft.

5.Turn the fan scroll end-for-end and bolt it to the support channels with the discharge towards the back. Mounting holes are provided in the fan scroll.

6.Align the fan and motor sheaves. Install the belt and adjust the belt tension. Refer toTableI-IP-1 for the correct belt size. The belt should depress about one inch under light pressure when properly adjusted.

7.Reverse direction of the motor rotation by exchanging any two of the three motor wire connections.

8.Exchange the front and top panel locations.
