Maintenance Instructions for your Fresh Air Ventilation System
WARNING
Electrical Shock Hazard.
Can cause personal injury or equipment damage.
Disconnect power supply before performing maintenance.
The Perfect Window™ Fresh Air Ventilation System must be maintained on a regular
basis for best efficiency. Honeywell recommends that the ventilator be cleaned and
checked at least twice a year, preferably at the beginning of each heating and cooling
season.
Check and Clean
EXTERIOR HOODS
Exterior hoods should be inspected at least once a month. Be sure exhaust and fresh
air supply hoods are not blocked up 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).
WARNING
Can cause personal injury or equipment damage.
Hood blockage can cause a change of pressure in building which can lead to
possible spillage from combustible appliances.
AIR FILTERS
Air filters should be cleaned twice a year. The standard filters supplied with your
ventilator are removable and washable.
1. Open access door and slide out core. Refer to Core Maintenance section for
cleaning instructions.
2. Remove filter clip.
3. Remove filters from the core and rinse with water or a combination of soap and
water. Do not clean in a dishwasher.
4. After cleaning, place filters (wet or dry) back in their position and reattach the
retaining clip.
