If an atomizing humidifier must be mounted upstream of the Infinityt Air Purifier, it should be mounted as far upstream as possible (at least 6 ft. recommended), and a standard disposable furnace filter should be mounted between the humidifier and the air purifier to trap hard water salt deposits and water droplets. Transitions If the return air duct or fan coil openings do not fit the Infinityt Air Purifier cabinet openings, gradual transitions are recommended to reduce air turbulence and maxim

The cell contains the ionizer wires, the ionizer ground plate, Fig. 15, item 1, and the charged and grounded collector plate assembly, item 3, of the plate-type cell. The plate-type and media-type cleaners are the same electrically. Physically, however, while the media-type cell has the same type of ionizer as the plate-type, a fiber glass pad between

When outdoor air is added, make certain that it is far enough ahead of the air cleaner to be mixed and warmed properly. If not, baffles must be installed to force mixing of the air. 2. Preheat coil. If a large amount of outdoor air is used, it must be heated. A thermostat should be used to control the heater. (A strip heater or hot water coil are typical heaters.)
