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).
