Adiabatic Pre-Cooling Media - Baltimore Aircoil Company Trillium Series Operating And Maintenance Instructions Manual

Adiabatic pre-cooling media

CLEANING
The digital controller provides automatic periodic cleaning of the pre-cooling media.
In extraordinary circumstances, if manual rinsing is required, the recommended procedure for cleaning of the pre-
cooling media is to turn the "pad maintenance switch", provided on the door of the electrical panel, to the "Hand"
position for a period of 1 to 2 hours. Never use a brush or high-pressure hose for cleaning of the adiabatic pre-
cooling media.
REMOVAL AND REPLACEMENT
The expected service lifetime of the pre-cooling media is 5 to 7 years if basic housekeeping practices and these
operating and maintenance guidelines are followed. If severe disposition causes reduced humidification efficiency
and reduced airflow, it is recommended that the pre-cooling media is replaced. New adiabatic pre-cooling media
are available from your local BAC-Balticare representative.
Media removal/replacement procedure:
1. Verify that the pre-cooling media are DRY! Removing a wet pad will create debris falling into the unit.
2. Remove top plate.
3. Remove water distribution pad.
4. Remove pre-cooling media.
For re-installation of the media follow steps 4 to 1 in reverse sequence.
