Sentence 9.32.3.12.(6)

Intent 1:

To limit the probability that condensate will freeze on heat recovery ventilator components, which could lead to the premature failure of motors or fans, which could lead to a loss of ventilation capacity.

This is to limit the probability of the inadequate control of:

• airborne pollutants,
• oxygen and other components necessary for breathable air, or
• relative humidity, which could lead to condensation, which could lead to the generation of pollutants from biological growth or from materials that become unstable on wetting.

This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.
