110 & 210 with controls
120 & 220 without controls
1. Attach frame mounting brackets to fan using the 4 3/4'' self tapping screw.
2. Position fan to desired location, mark holes on radiator channels or frame.
3. Rotate fan blades to insure that they are free of obstruction.
4. On the marked hole locations drill 13/64" holes.
5. Secure the fan to radiator using the provided 1/4" x 1" self tapping screws.
6. Check fan rotation.

Fan Wiring Instructions
Note: Does not apply to 120 & 220 Models
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
colored motor wires at fan. Attach a length of the large diameter (12 AWG) black wire to the black
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.
Colored
Step 3: Connect the motor wires to the control module
(Red wire to the "M+" terminal and black wire to the "M-" terminal).
Step 4: Disconnect the negative battery lead for safety while nishing 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 ns
Install temp. probe near inlet hose...
then replace 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 ns near the inlet hose. Reinstall the black insulator cap.
Step 11: Adjust the temperature control knob on the control box
If you disconnected any hoses or drained coolant to install the fan, reconnect the hoses and rell
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 hand held thermometer (positioned near the inlet hose) or the vehicle's temperature gauge, 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.
The Flex-a-lite Limited Warranty
Flex-a-lite Consolidated, 7213-45th St. Ct. E. Fife, WA 98424, Telephone No. 253-922-2700, warrants to the original purchasing user, that all Flex-a-lite products to be free of defects in material and
