CORE
Clean the core twice each year.
1. Open the access door and carefully grip the ends of the core and pull evenly out-
ward. The core can be snug, but it will slide out of the cabinet.
NOTE: Do not handle the fins because damage can occur.
2. Once out of the cabinet, remove the filters (refer to Air Filter Maintenance sec-
tion).
3. Wash the core in warm soapy water—do not use a dishwasher.
4. Reinstall the clean filters.
5. Reinstall the clean core.
NOTE: Do not detach the foam on the ends of the core or the core label, water does
not damage them.
To install the clean core:
1. First mount the bottom core guide into the bottom H channel.
2. Mount either side core guide, followed by the other side.
3. Mount the top core guide into the top H channel.
4. With all four comers in place and the core straight and even, push on the core
center until the core slides to the back of the cabinet.
NOTE: The core will appear to stick out from the cabinet approximately 1/8 in.
(3mm). It is designed this way, so that the access door will fit tightly against
the core.
