The metal filter included with this unit should be cleaned every 6 months using water and a mild soap.
To remove the filter(s), open the door, release the filter retaining clip and pull filter(s) out. Allow the
filter to dry completely before putting it back in the unit; when reinserting it in the unit, make sure that
it is standing straight.
•
Inspect the outdoor air intake at least once a year.
•
During the first year of operation, it is recommended to inspect your unit at a higher frequency,
especially if you live near a highway or in an area where there is a lot of construction work, generating
lots of dust. Your filter(s) may need more frequent cleaning or replacement in these types of
environments.
•
Replace the optional MERV filter at least once a year; do not attempt to clean and reuse the optional
MERV filter.
•
These recommendations may change according to the environmental conditions in your area.

operation mode of your Supply Fan can be changed from a Code-Compliant one (modes 1 to 3) to a

by your installer. If in doubt, refer to your HVAC contractor.
