VESDA filter
The VESDA filter sensor notifies you through the ECS when a filter must be changed. HP recommends that you periodically inspect and change each VESDA filter. A VESDA filter can be replaced during normal HP POD 40c NA operation.
You need a screwdriver for installation.
Removing the VESDA filter
1. Remove the filter cover on the front of the VESDA unit.
