For ICM in operation

When ICAD is installed/serviced, on a cold/frozen valve; do the following:

1.Make sure the old grease is totally removed before mounting a new EPDM O-ring and PTFE support ring.

2.If there is any ice or moisture present, it must be removed prior to applying the grease. The ice/moisture can be removed with an electrical hot air gun.

3.After ice removal by heater, ensure that the ICM adapter is totally dry before mounting new EPDM O-ring and PTFE support ring

4.Install the ICAD actuator on the ICM adapter making sure it is pushed completely down. Fasten the the 3 set screws using a 2.5 mm hexagon key.
