SECONDARY CIRCUIT
IONIZING-COLLECTING CELL
NOTE:
The cell is electrically energized through a contact terminal located at the top center
of the cell. The ionizing wires and alternating collector plates are electrically
charged while the interleaving plates are grounded.
If the space between the charged and grounded plates is bridged with conductive
or semi-conductive material, a short circuit develops. The bridging or short may be
caused by damaged plates, or foreign material lodged between/on the
components. Since the cell should be periodically removed from the unit to wash
away collected dirt, it is susceptible to physical damage. The cell also contains the
ionizing wires which, due to their function, have been designed with minimal
structural support and are susceptible to breakage. However, trouble related to a
shorted collector cell is readily shown by the Red CELL ENERGIZED light and can
be quickly isolated by a simple procedure.
To determine if a short exists in one or both of the collector cells, turn the Electronic
Air Cleaner OFF and remove both electronic cells from the cabinet. Shut the door
and repower the unit. If the Red CELL ENERGIZED light comes on, an electrical
short exists in one or both of the electronic cells. Replace the cells in the unit, one at
a time, to determine which cell is shorted.
Most troubles in the cell can be visually detected and corrected (page 12 - Table 1).
The ionizer collector cells are not designed for field repair. Ionizing wires and
insulators can be field replaced. It is not recommended that you attempt to replace
other cell components (i.e. Collector plates, end plates, ionizer supports).
