Flex 130 User manual

Through Core Mounting Instructions

(SEE DIAGRAM “A”)

Step 1.Position the electric fan against the back of the

radiator, and mark the holes for mounting.(Some appli-

cations may have A/C condensers and/or transmission

coolers on the front of the radiator. Additional adjust-

ments

or modifications may be necessary for installa-

tion)

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

obstructions.

Step 3. With a small phillips screwdriver pass through

the marked holes, carefully spread the fins to allow easy pas-

sage for the nylon bolts (4 for the single fan unit, 4 for the double fan unit).

Pass the bolts through the shroud holes then twist the bolts through the radiator.

Step 4. Slide the rubber washer, then the nylon washer onto the nylon bolt and finger tighten

nylon nuts until snug.

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

Radiator Support Channel Or Frame Installation

(SEE DIAGRAM “B”)

Step 1. Attach frame mounting brackets to fan using

nylon bolts, cut them to 1", use nylon nuts to secure.

Step 2. Position fan to desired location, mark holes on

radiator channels or frame.

Step 3. Rotate fan blades to insure that they are free

of obstruction.

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

Step 5. Secure the fan to radiator using the provided

1/4" x 1" self tapping screws.

Step 6. Check fan rotation.

Fan Wiring Instructions

Step 1: Locate mounting point for control

Locate a mounting point for control near inlet side of radiator. Control needs to be placed within 18"

of radiator inlet hose. You may want to mount next to radiator on fender well. Mount control using

screws provided.

Step 2: Wire the fan motors (refer to Wiring Diagram, below)

Using the bullet connectors provided, attach a length of the large diameter (12 AWG)

red

wire to the

black

motor wires at fan. Attach a length of the large diameter (12 AWG)

black

wire to the

red

motor

wires at the fan. Once the fan is in place, these will attach to the control module. If mounting the

control somewhere in the engine compartment, leave enough wire to reach the control module, but

do not connect yet.

Step 3: Connect the motor wires to the control module using the female connectors provided

(Red wire to the "M+" terminal and black wire to the "M-" terminal).

Step 4: Disconnect the negative battery lead for safety while finishing the wiring. Use the large

diameter red wire to run power directly from the battery positive (+) terminal to the "B" terminal on the

control module. Connect the fuse holder in-line with this wire, as shown, but do not insert the fuse

yet. Use the blue female, ring, and butt connectors provided.

Step 5: Use the large diameter black (12 AWG) wire to run from the negative (-) battery terminal to

the "G" terminal on the control module. Use the blue female connector and ring connector provided.

Step 6: Use the small diameter red wire (14 AWG) to connect the "+" terminal on the control module

to a positive power source.

NOTE: Attaching this wire to an ignition-controlled source will shut

off the fan when the engine is turned off. Attach this wire to an uninterrupted (always hot)

power source to allow the fan to continue running after the engine is shut off.

Use the blue

female connector and fuse taps (included) if necessary.

Step 7: (Optional) For air conditioning control (if desired) connect the "C" terminal on the control

module to the

positive

wire that triggers the A/C compressor using the small diameter green (14

AWG) wire. Using a voltmeter, determine which wire coming from the compressor is the

positive

trigger wire. Use the 3-way connector (included) to tap into this wire and send a signal to the fan

control module. The fan will cycle on and off with the A/C clutch when the A/C is turned on.

Step 8: (Optional) For manual switch operation, use Flex-a-lite p/n 31148. Connect the switch as

shown on the wiring diagram (previous page). Connect the "M" terminal on the control module to the

"1" terminal on the switch. Connect the "2" terminal on the switch to a positive 12v power source.

Connect terminal "3" on the switch to a good ground (for switch illumination).

NOTE: To prevent

thermostatic activation (if only manual switch operation is desired), omit the lead to the "+"

terminal of the control box. "B", "G", "M+" and "M-" must remain connected. If not using a

Flex-a-lite manual switch, do not connect a ground wire to the switch!

Step 9: Use the zip ties provided to secure the wires and prevent them from interfering with fan

blades, belts, and pulleys in the engine compartment. Reconnect the battery and insert the fuse

provided.

Step 10: Insert the temperature probe into the radiator fins

Install temp. probe near inlet hose... then install the insulator cap.

Locate the inlet hose from the engine to the radiator. Remove the black insulator cap and insert the

temp. probe through the radiator fins near the inlet hose. Reinstall the black insulator cap.

If you disconnected any hoses or drained coolant to install the fan, reconnect the hoses and refill the

radiator. Press the control knob (included in wiring kit) onto the control box shaft. Turn the knob

clockwise until it stops. Start the engine and allow it to idle. Using a thermometer (positioned near

the inlet hose) or the vehicle's temperature guage, monitor the temperature. When the coolant temp.

is slightly above normal (or desired temp.), turn the knob counter-clockwise just until the fan turns on.

From now on, the fan should activate at this temperature setting. Adjust as necessary to maintain

desired temperature.

Step 11: Adjust the temperature control knob on the control box
