PLAN THE INSTALLATION
Adequate ventilation requires that both intermittent and
continuous contamination be controlled.
Intermittent ventilation must be provided in the bathroom
and kitchen. The bathroom requires 8 air changes per hour.
(Multiply bathroom sq. footage by 1.1 for proper fan sizing)
The kitchen requires a minimum of 150 CFM capacity (71
l/s) when a ducted range hood is used. If a kitchen fan is
used, determine fan capacity by multiplying the room's sq.
footage by 2. All are run intermittently to control pollution at
the source.
Continuous ventilation, while the house is occupied, pro-
vides the flow of fresh air for good indoor air quality.
This ventilator is intended to for continuous operation,
supplying fresh air to the entire house.
