the Molykote G 4500 grease provided.
2. Install the IFV Actuator to the Bonnet/Function Module ensure the actuator is fully inserted with
the wire connection ports facing up.
3. Secure the IFV Actuator to the Bonnet/Function Module using the three (3) set screws and a 2.5
mm hex bit. Torque to specification.
4. Attach the Red (power) and Black (signal) cables to the IFV by turning the collars, located on the
cable ends, in a clockwise rotation.

The ICM valve must not be in its fully opened position while the ICAD motor is calibrated with the
valve. Therefore, if the opening degree of the ICM valve was changed from the factory setting, it
should be set to an opening degree between 0% and 75% using the manual magnet tool. To easily
ensure correct positioning, turn the manual tool counter-clockwise until it is clear that it cannot be
turned further.
Programming is required anytime the IFV Controller is replaced.
