Through Core Mounting Instructions

(SEE DIAGRAM “A”)

1.Position the electric fan against the back of the radiator, and mark the holes for mounting.(Some

applications may have

A/C condensers and/or transmission coolers on the front of the radiator.

Ad-

ditional adjustments or modiﬁcations may be necessary for installation)

2. Rotate fan blades to make sure they are free of obstruc

tions.

3. With a small phillips screwdriver pass through the marked

holes, carefully spread the ﬁ

ns to allow easy passage for

the nylon bolts (4 for the single fan unit, 6 for the double

fan

unit

). Pass the bolts through the shroud holes then twist

the bolts through the radiator.

4. Slide the rubber washer, then the nylon washer onto the

nylon bolt and ﬁnger tighten nylon nuts until snug.

5. Once again, rotate fan blades to insure that they are free

of obstruction.

Radiator Support Channel Or Frame Installation

(SEE DIAGRAM “B”)

Attach frame mounting brackets to fan using nylon bolts, Cut them to 1", Use nylon nuts to secure.

2. Position fan to desired location, Mark holes on radiator channels or frame.

3. Rotate fan blades to ensure that they are free of obstructions.

4. On the marked hole locations, drill 13/64" holes.

5. Secure the fan to radiator using 1/4" self tapping screws.

6. Check again to be sure the fan blades rotate freely.

Find a circuit that is "hot " when the key is in the "ON" position. NOTE: DO NOT use the DRL or brake/taillight fuse! Attach the included fuse tap to fuse. Attach a female connector to the thin red wire included and connect to the fuse tap. Trim the wire so that it will reach the VSC.

The Variable Speed Control has new features. At the set temperature, the fans will come on at 60%; this reduces the load on your charging system. If the temperature rises, the fan speed will increase. If your set temperature is 195°F, then between 195° and 205° the fan speed will increase from 60% to 100%. So after a 10-degree rise from the set point, the fans will be running at 100%. Initial Start-up and Adjustment Procedure 1. Turn ignition on. After 6 seconds, LED #L4 should light up.
