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.

2.2 INSTALLING 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.
2.3 INSTALLING 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.
