FILTER MAINTENANCE
• The control unit contains a high volume air blower that requires filtered air for proper
operation.
• The two-part filter system is located on the bottom rear of the unit.
•
The larger outer filter is designed to be removed, cleaned, and re-used. [Fig. 1 & 2]
• The smaller inner filter is located directly beneath the larger removable filter [Figure 3]. THE SMALLER

system should be performed at least once every 180 days of use. If the control unit is used in an area with
high concentration of dust or cigarette smoke, the filter should be cleaned as frequently as once every 30 or
60 days for maximum operation.
