Hoods
Monthly
Make sure the exhaust and fresh air supply hoods are not
blocked or restricted by leaves, grass, or snow. In winter, it is
especially important to make sure snow is not blocking the hoods
or that frost has not built up on the wire mesh (bird screen).
Clean Air Filters
Quarterly
1) Open access door.
2) Carefully grip the ends of the core and pull evenly outward.
The core may be snug but will slide out of the cabinet.
3) Remove the filter clips (if installed) and then the air filters.
4) Rinse the air filters with cold water or a combination of mild
soap and water. Shake them once or twice to remove excess
water.
5) Install the clean filter(s) (wet or dry) back into their positions
against the core and install the filter clips, if present.
6) Slide core back into its original position.
Note
• The standard air filters equipped with your HRV are
removable and washable.

Do not wring out the air filters or clean them in the
dishwasher.

maintenance, turn the electrical power unit off at the disconnect switch(es). Unit may have multiple
