REPLACING THE IONIZING WIRES
Ionizing wire breakage is minimal because of the constant tension design
and fixed location of the ionizing wire supports. When an ionizing wire
breaks, the efficiency of the Electronic Air Cleaner will decrease slightly.
However, the unit will continue to operate with broken ionizing wires as long
as the broken wires have not caused a short circuit of the unit. Remove all
loose and broken wires as soon as they are identified.
Although the replacement of the ionizing wires can be attempted by a
homeowner, it is recommended that a qualified HVAC contractor be
contacted for replacement parts and/or servicing. Wires are supplied in a
coiled spring configuration, with a clinch nut on each end of the wire.
Replacement requires a pair of needle nose pliers. Exercise caution in
removing any broken wires in the collector cell. This will prevent accidental
shorting of the cell and reduce the need for further maintenance.
Use the following procedure when replacing an ionizing wire.
1. Ensure that all power to the Electronic Air Cleaner is OFF, remove the
access door and remove the ionizing-collector cells from the unit.
2. Carefully remove all remains of the broken wire.
3. Grip the new wire at each end of the wire with your thumb and index
finger. While stretching the wire to approximately 6" allow one end of
the wire to uncoil between your thumb and index finger.
4. Place one end of the wire in the slot of the stainless steel support on
the collector cell from the front of the cell. This support is partially
covered by the cell brace in front of the support.
5. Grip the other end of the ionizing wire with needle nose pliers and
insert the terminated end of the wire into the slot on the support bar of
the opposite end of the collector cell.
6. The wire should be tight enough to be self supporting and remain
suspended between the two support slots in the support bar.
