Flex-a-Lite 330 Dual Electric Fan with Thermostatic Control and A/C Relay - Manual (Page 3)

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 “+” ter-
minal 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 pro-
vided.
Step 10: Locate the temperature sensor. Gently push probe through fins in radiator as close to the
upper radiator hose as possible. The rubber insulator cap should be used when possible to insulate
any of the probe coming through the front side of the radiator.
Install temp. probe near inlet hose... then install the insulator cap.
Step 11: 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 hand held temperature
sensor (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.
