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 specically

designed for use in systems with an air handler. Models FH8000F1625 and FH8000F2025 are specically

designed for use in systems with a forced air furnace. The Honeywell Enhanced Air Cleaner is CSA certied

for shock and electrical re 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.

Humidiers

An evaporative humidier can be mounted upstream of the Honeywell Enhanced Air Cleaner. It is best to

install atomizing humidiers 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 humidier

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 lter should be mounted

between the humidier 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 t the Honeywell Enhanced Air Cleaner cabinet openings,

gradual transitions are recommended to reduce air turbulence and maximize efciency.

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 tting.

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 tting.

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.
