VII / Maintenance
A. Pre Filter- KBA& KBAP systems come from the factory with a washable pre-filter installed on the
evaporator inlet to prevent dust and debris from entering the HEPA filter that is also pre-installed. You will
need to periodically clean the pre-filter based on your air quality, for optimum performance inspect/clean
this filter every 30 days, and more often if operated in poor air quality. Open the filter access door, below
the control by releasing the 2 slotted fasteners on the right side of the compartment. Remove the pre-filter
from the door frame and use a compressed gas in an approved area wearing the proper PPE to blow
through the filter to remove loose particles and then rinse the filter with clean water, allow complete drying
before re-installing. Failure to maintain the pre filter will cause restricted air flow and low overall unit
performance.
