SECTION 2

2.1 MOUNTING THE CONTROL BOX

The control box should be mounted near the outlet manifold of the aftercooler. Make sure that the control box is close enough so that all components can reach the box when in- stalled.

Drill the four pilot holes in the mounting surface using a 1/8" drill. Reference Figure 2- A for dimensions.

The control box will be mounted with the hinged side of the enclosure on the bottom.

Fasten the controller in place using the four

(4)#12-14 x 1" long self-tapping screws supplied with the kit.

2.2INSTALLING THE SENSOR AND THERMOWELL

A 1/2" NPT or larger connection in the system piping between the outlet of the aftercooler and the inlet of the separator is required for the thermowell and sensor.

Thread the thermowell and the 1" x 1/2" bushing (if required) into a connection between the aftercooler outlet and the separator.

Place some heat conductive compound into the thermowell. Place the sensor into the thermowell and fasten it in place using the clip supplied with the thermowell. Reference Figure 2-B.

Install the cord grip connector into the control box as shown in Figure 2-B. Push the sensor cable through the connector. Wire the sensor cable to the controller circuit board terminals as shown in Figure 2-F. Tighten the grip nut on the connector.

2.3INSTALLING THE HEAT TAPE AND INSULATION

Install the cord grip on the control box as shown in Figure 2-C.

Cut the plug end off the heat tape. Strip back the wires.

Push the wire end of the heat tape through the connector. Allow enough cord inside the box for wiring. Connect the heat tape to the proper terminals in the control box as shown in FIGURES 2-F. Tighten the grip nut on the connector.

Run the heat tape to the separator. Wrap the heat tape around the separator as shown in Figure 2-C. Do not overlap the tape.

Wrap the insulation around the piping and heat tape as shown in Figure 2-C.
