CHANGING THE FILTER
CAUTION: THIS PROCEDURE CAN CAUSE SEVERE BURNS. USE PROPER PROTECTION.
Changing the filter in the Model 270 Heated Filter Assembly is extremely easy. Using gloves to protect the hand, grasp
the cap on the end of the filter body opposite the probe and turn it counterclockwise. The cover may be hot to the touch
and may cause burns to the hand if not protected. Removing the cover exposes the filter. The cover is secured to the
assembly with a retainer chain. Reach into the heated oven with pliers to pull out the old filter.
Inspect the O-Rings which are at each end of the filter to ensure they are still elastic and will seal the filter. Replace
O-Rings if they are charred or deformed.
Replace the filter with a new one, again handling it with pliers. Ensure that the filter is pushed in the center of the oven so
that it is in contact with the O-Ring on the far end of the filter. Screw the cap back on the filter body. The filter replacement
procedure is complete.
