4.5 Shellside/Vessel Flooding
If a tube within the exchanger develops a leak, D.I. water will begin entering the shell of the
exchanger. In this manner a tube leak will cause the condensate to begin backing up and filling
the lower portion of the exchanger vessel. When the level reaches approximately four inches
deep, a float switch will trip which will activate an alarm. Audio alarms on both the main and
user‟s remote panels will be energized, and the touchscreen will indicate that this flooding
condition exists.
Additionally, if the user‟s steam trap or condensate-removal system fails, the vessel will also
begin to flood with condensate. This will also cause the float switch to trip which will activate
the Vessel Flooding alarm. Audio alarms on both the main and user‟s remote panels will be
energized, and the touchscreen will indicate that this flooding condition exists.
This alarm condition has no affect on the operation of the unit and serves as an indicator of the
condition only. Once the alarm condition is disappears or is resolved it will reset
automatically.

4.6 Water Leak
The leak sensor located at the drip pan senses any water that is present and triggers an alarm
should it detect any fluid in the drip pan. This alarm condition has no affect on the operation
of the unit and will not initiate Auto-Shutdown or Auto-Isolation. This alarm automatically
resets once the condition disappears or is resolved.
