Note: Always turn off and unplug the incubator before carrying
out this procedure.
Replace the filter at least once per year, or when the filter is
noticeably discolored.
Exercise caution when removing the ceiling air duct. A plastic
blower fan and the fragile head of the temperature and CO
2
sensors are located just above the duct and just to the right of
the duct.
Dismount the Air Duct (Ceiling Liner)
Use firm but careful pressure to remove the duct from the
front mounting pins, one pin at a time.
Dismount the back of the duct from the rear mounting pins
by carefully pushing the back of the duct.
Lower the front of the duct. This safeguards against accidentally
striking the blower fan and sensor heads with the duct.
Pull the duct and attached HEPA filter out of the incubation chamber.
Replacing the HEPA Filter
Remove the black plastic cap from the HEPA filter by pulling
down on it.
Remove the old HEPA filter by pulling down. It will snap out
without difficulty.
Snap the new HEPA filter into position on the duct. It may be
necessary to tilt it slightly to one side.

Snap the black plastic cap back into position in the center of
the HEPA filter.
Reinstall the duct
See the Install Chamber HEPA Filter and Duct procedure
