Installing the Conduit | Honeywell AC-140-7, AC-220-7

SECTION 2

2.4INSTALLING THE CONDUIT

Install the straight conduit connector on the control box. Reference Figure 2-D.

The supplied conduit will be used to run between the aftercooler and the control box. Connect the conduit to the straight connector.

Install the 90 degree elbow connector on the aftercooler. Reference Figure 2-D.

2.5 INSTALLING THE TRANSFORMER JUMPERS

WARNING

BEFORE STARTING THIS PROCEDURE, TURN OFF ELECTRICAL POWER. FAILURE TO HEED THIS WARNING MAY RESULT IN SERIOUS PERSONAL INJURY AND/OR DAMAGE TO THE UNIT.

This kit was designed to operate at 230V-3PH-60Hz or 460V-3PH-60Hz. Two jumpers were shipped inside the control box. They must be installed on the transformer before connecting the power to the control box. Install the jumper(s) as shown in Figure 2-E for the desired voltage.

CAUTION

It is important that this procedure be properly completed before continuing with installation. This kit will not operate without the jumpers.

Damage to the control box will occur if the jumpers are improperly installed.

2.6 ELECTRICAL CONNECTIONS

WARNING

BEFORE STARTING INSTALLATION PROCEDURES OR ATTEMPTING TO MAKE ANY WIRING CHANGES, TURN OFF ELECTRICAL POWER. FAILURE TO HEED THIS WARNING MAY RESULT IN SERIOUS PERSONAL INJURY AND/OR DAMAGE TO THE UNIT.

WHEN INSTALLING THIS KIT ALWAYS COMPLY WITH THE NATIONAL ELECTRICAL CODE AND ALL OTHER APPLICABLE FEDERAL, STATE AND LOCAL CODES.

A 7/8" hole in the top right side of the control box is provided for incoming power conduit. The hole can be enlarged if necessary.

The control box is designed for 230V-3PH-60Hz or 460V- 3PH-60Hz operation. The transformer jumpers must be installed as outlined in Section 2.5 for the desired voltage.

Make the necessary wiring runs and connections for the main power supply.

Remove the junction box cover on the aftercooler for access to the junction box. Make the necessary wiring runs through the conduit from the aftercooler to the control box. Fasten the

conduit to the connector on the aftercooler. Reference FIGURE 2-D.

Make the wire connections at the junction box on the aftercooler. Reference FIGURE 2-F. Fasten the junction box cover to the aftercooler.

Complete the wire connections inside the controller as shown in FIGURE 2-F.

Once all wiring connections have been properly made, the rotation of the fan should be checked. The fan must rotate in the proper direction for maximum performance. Reference the operator's manual supplied with the aftercooler for the correct rotation direction. Also, check the aftercooler for a rotation direction label.

To check the rotation, turn on the power supply to the aftercooler. If the fan does not rotate in the proper direction, any two of the power leads to the motor can be switched.
