7 MAINTENANCE
7.1 How to Maintain the Product
7.1.1 Changing Filters -
Recirculating equipped units only (MB1009 option)

Filter change frequency is based on laboratory HVAC settings and Formalin fume exposure and therefore
variable in life
 To change the filters in your station, you will need to remove the thumb screws that hold the door closed.
 The filter door may now be opened. It is hinged at the bottom and may need minor prying to open if
operated in a dusty environment.
 Depending on your model the recirculating unit may have 3-6 filters.
All replacement filters will use a Mopec BF035 Potassium Permanganate Filter in each slot.

Install the new filters with the white side down and black mesh up top.

Close filter door and tighten thumb screws.
7.1.2 Checking Filters
Filter life is dependent on the amount and concentration of formalin fumes passing through it. This section describes
how to check a filter so that a proper filter life can be predicted and planned in a lab.
 The potassium permanganate (KMnO4) filters change color from bright purple to a dark brown with the
amount of exposure. To check this please remove a used filter per section 7.1.1 above.
 Pry open the corner of the filter and dump out some pellets for examination.
 To determine if the potassium permanganate has been exhausted remove a pellet and cut it in half.
