50-55 Auxiliary Electra-Fan

Installation Instructions

(55 with out TEMP Control)

The Auxiliary Electra-Fan should be installed in accordance with

the following instructions.

Improper installation may result in premature failure and void the

Limited One-Year Warranty.

MOUNT FAN TO RADIATOR OR A/C CONDENSER-All

Installations:

INSTALLING THESE FANS IN FRONT OF THE RADIATOR

WILL RESULT IN A PUSHER FAN;

INSTALLING IT BEHIND THE RADIATOR WILL RESULT

IN A PULLER FAN. REGARDLESS, IN ALL INSTALLA-

TIONS, THE SIDE OF THE UNIT WITH THE FAN BLADES

EXPOSED SHOULD ALWAYS FACE THE FRONT OF THE

VEHICLE.

1) Determine whether the fan will be installed in FRONT of

the radiator or condenser (pusher) or BEHIND radiator or

condenser (puller).

2) Position fan on the radiator or A/C condenser where it

will have at least 3/4” clearance to any other object. Using a

small Phillips screwdriver, carefully spread the radiator fins

to allow the mounting bolts to pass through the radiator. Be

careful not to damage the radiator tubes.

3) Fit 4 nylon bolts through the fan, and slip a rubber washer

over each bolt. See FIG. 1.

4) Fit the fan to the radiator, feeding all four screws through the radiator, and add a plastic washer to each bolt.

5) Push a nylon push-nut up each nylon bolt until snug.

6) Turn push nut clockwise until tight, then trim off excess bolt, leaving 1/4” exposed.
