Outdoor Air Intake; Uv Lights - Honeywell Home F300 Serie Guía De Instalación Profesional

Outdoor Air Intake

Return air temperature must be at least 40°F (4°C). Lower temperatures can cause ionizer wire failure. If
outdoor air is used, warm it upstream from the air cleaner by:
• Making sure the outdoor intake is far enough upstream from the air cleaner so the return and outdoor air
is thoroughly mixed. Stratified air can dump a stream of very cold air into one section of the air cleaner.
• Adding baffles upstream from the air cleaner to force thorough air mixing.
• Installing a Resideo Heat Recovery Ventilator or Energy Recovery Ventilator that transfers up to 80
percent of the heat from the exhaust air to the incoming outside air. This keeps the incoming air above
40°F (4°C) and reduces energy usage.
• Installing a preheater if large amounts of outdoor air are used. The preheater, which could be an electric
strip heater or hot water coil, should be controlled by a thermostat. Hot water or steam coils should be
protected by a freeze-up control.

UV Lights

Germicidal UV lights can cause degradation of the media postfilter. The UV light should be located out of line
of sight or a minimum of 3 feet from the filter. Otherwise the filter may need to be replaced more frequently.
