Getting the most from your Fresh Air Ventilation System
HOW MUCH VENTILATION DO I NEED?
During the seasons that your windows and doors are closed (winter and summer if you
have air conditioning), the ventilator should operate continuously when the home is
occupied, and either continuously or intermittently when not occupied.
For most installations, the ventilator will normally be set to operate continuously on low
speed with the option of going to high speed as the need arises. For example, if you
are entertaining and there is a large number of people present (some may be
smoking), the ventilator should be switched to high speed.
YOUR VENTILATOR MAY BE SET TO HIGH SPEED BY:
1. selecting the highest speed on the ventilator or
2. if the system includes an optional remote control, switch it to the ON position.
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).
