Common Questions and Answers
Q. Why isn't my air cleaner cleaning my air?
A. The air cleaner is most likely working just like it was designed.
However, many factors can affect the performance of the unit. Are cold air
registers located in the ceiling? If so, it will be difficult for the air flow to
carry heavier particulates to the air cleaner. If the dirt doesn't get to the air
cleaner, it can't be removed from the air. Are both the Red and Green lights
illuminated? If not, then the unit may be in need of servicing. Contact your
local HVAC dealer for assistance.
Q. It still isn't cleaning my air the way I want it to. What can I do?
A. We recommend that you run the blower continuously so that the air
movement will carry the dirt to the air cleaner. Unfortunately, there will
always be some dirt that is left behind on the appliances, furniture, etc.
Regular dusting is recommended to stir up these pockets of dust so that
they can enter the airstream and be removed by the Electronic Air Cleaner.
Q. When I turn on my Electronic Air Cleaner, the lights come on for a couple
of seconds and then turn off. The air cleaner isn't working!
A. The air cleaner is fine as long as both the Red and Green lights are
coming on. Try turning the HVAC blower OFF and then turning the
Electronic Air Cleaner on. This should solve the problem.
Q. What is the zapping noise I'm hearing from my unit? Should I be
concerned?
A. The zapping or popping noise that you are hearing is the sound of larger
particles being "vaporized" by the ionizing-collector cell. This is normal
and is no cause for alarm. As your HVAC system blower moves the air
through the ductwork and allows the Electronic Air Cleaner to clean the
air, the noise will diminish. However, there will always be instances when
larger particles enter the ionizing-collector cell.
Q. Should I hear this zapping noise all the time?
A. All Electronic Air Cleaners will occasionally zap or pop as larger particles
pass through the ionizing-collector cells. However, if the sound is
constant or is repetitive in nature, then a large particle may have become
lodged in the ionizing-collector cells and they may require cleaning. If
cleaning the ionizing-collector cells does not stop the noise and there
are no large particles trapped in the ionizing-collector cells, then the
cause could be a broken/loose ionizing wire, bent collector plate or
other mechanical reason. Please contact your local HVAC dealer for
assistance.
