Most A9 alarms are due to improper installation. Please check the following:
1. Make sure the ICAD motor is centered on the valve stem. You can do this by adjusting the set screws at the base of the motor.
2. Check that an O-ring has been installed at the base of the ICM valve stem and is in good condition.
3. Apply plenty of grease to the O-ring and the magnets in the ICAD actuator. The grease provides a moisture barrier on the O-ring, and greasing the magnet inside removes air gaps found between the beveled edges of each magnet.
