THE “FILTER CHECK” FEATURE I DENTIFIES WHICH DUST FILTER (Pre-Filter or HEPA) NEEDS
REPLACEMENT.
1. If the “ CHECK FILTER ” warning comes on, go to the User Interface and press the
“Menu/Enter” button. Press the “left or right arrow” keys to scroll through the menu
functions until you find the “ FILTER CHECK ” feature.
2. Press the “Menu/Enter” button to initiate the “ FILTER CHECK ” process.
3. Filtrabox will assess the status of all the Dust Filters in your systems and then prompt you to
remove the Pre-Filter . Follow the instructions on the screen.
4. Filtrabox will then advise you to replace either the HEPA or the Pre-Filter depending on
their actual conditions. Or, the system will advise you to consider upgrading to a more
powerful model if the Airflow% setting is too high, which would cause the filters to be
inefficiently used (causing frequent filter changes).
REPLACING THE CYLINDRICAL PRE-FILTER
! Important Note: The Pre-Filter “Retaining B ar ” must be in locked position
while Filtrabox is in operation. Failure to do so will allow the Pre-Filter to slip off
the spigot and prematurely block your HEPA filter.
1. Open the Access Door on the Main Chassis , by turning the two Black Knobs on the door.
2. Unlock the Pre-Filter Retaining Bar by pushing it away from you.
3. Slide the Pre-Filter towards the Retaining Bar and off of the Spigot.
4. Roll the spent Pre-Filter out of the Chassis.
5. Roll a new Pre-Filter into the Chassis with the blue side of the filter facing the Spigot.
6. Slide the Pre-Filter towards the Spigot until it is fully engaged onto the Spigot.
7. Lock the Pre-Filter in place by pulling the Retaining Bar towards you until it is at a right angle to
the bottom surface of the filter.
8. Close the Access Door and turn the two Black Knobs to seal the door.
