16.1 Filter Considerations
• A filter must be installed within the system.
• A filter channel is provided in the unit, at the bot-
tom of the Blower/Filter compartment.
• For customer ease of fil ter maintenance, it is
recommended that a properly sized remote filter
grill(s) be installed for units that are difficult to
access. Airflow should not exceed the maximum
rated velocity of the filter being used.
