2. Once out of the cabinet, remove the filters (refer to Air Filter Maintenance sec-
tion).
3. When the core is dry, clean it with only a vacuum cleaner. Vacuum the filter sides
of the core by pulling any dirt back out of the core, not by pulling dirt all the way
through the core.
4. Reinstall the clean filters.
5. Reinstall the clean core.
TO INSTALL THE CLEAN CORE:
1. First mount the bottom core guide into the bottom Core Guide Channel.
2. Mount either side core guide, followed by the other side.
3. Mount the top core guide into the top Core Guide Channel.
4. With all four corners 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 is designed to appear to protrude from the cabinet approximately
1/8 in. (3mm) so the access door fits tightly against the core.
GENERAL MAINTENANCE
Twice a year, wipe the inside of the cabinet with a damp cloth to remove dirt, bugs and
debris that can be present.
FANS
If the fans accumulate dirt, it could cause an imbalance and excessive vibration of the
ventilator. A reduction in air flow can also occur. In a newly constructed house, this
often happens within the first year due to heavy dust residue in the entire system. It
can also occur periodically depending on the outdoor conditions. If you suspect that
service is required, please contact the ventilator installer or your local HVAC
contractor.
