Application Considerations - Honeywell TrueCLEAN FH8000A1620 Guide D'installation

Application Considerations

The Honeywell Enhanced Air Cleaner is designed for use in the return air duct of a forced air heating,
cooling, and ventilation system. Models FH8000A1620, FH8000A2020 and FH8000A2520 are specifically
designed for use in systems with an air handler. Models FH8000F1625 and FH8000F2025 are specifically
designed for use in systems with a forced air furnace. The Honeywell Enhanced Air Cleaner is CSA certified
for shock and electrical fire hazard only.
Air Conditioning
The Honeywell Enhanced Air Cleaner should be installed in a system so that all the return air is circulated
through the Honeywell Enhanced Air Cleaner. It should be located upstream of the air conditioning
equipment. This will help keep the equipment clean and prevent condensation from forming within the
Honeywell Enhanced Air Cleaner.
Humidifiers
An evaporative humidifier can be mounted upstream of the Honeywell Enhanced Air Cleaner. It is best to
install atomizing humidifiers downstream of the Honeywell Enhanced Air Cleaner because hard water salt
deposits and water droplets may damage the Honeywell Enhanced Air Cleaner. If an atomizing humidifier
must be mounted upstream of the Honeywell Enhanced Air Cleaner, it should be mounted as far upstream
as possible (at least 6 ft. [1.8 m] recommended), and a standard disposable furnace filter should be mounted
between the humidifier and the Honeywell Enhanced Air Cleaner to trap hard water salt deposits and water
droplets.
Transitions
If the return air duct or fan coil openings do not fit the Honeywell Enhanced Air Cleaner cabinet openings,
gradual transitions are recommended to reduce air turbulence and maximize efficiency.
1620/2020/2520 – No more than 20 degrees (about 4 in. per running ft.) of expansion should be used on
each side of the transition fitting.
1625/2025 – No more than 45 degrees (about 8.5 in. per running ft.) of expansion should be used on each
side of the transition fitting.
Turning Vanes
If the Honeywell Enhanced Air Cleaner is installed adjacent to a 90 degree duct elbow, turning vanes should
be added inside duct to improve air distribution across the face of the Honeywell Enhanced Air Cleaner.
