OPERATION
1. Turn on furnace or air conditioner to get air flow
through the duct.
2. Press the lower section of "ON-OFF" rocker switch
(Figure 21 ).
3. Close the grille by rotating into position on
the cabinet (fig. 19). Lock in position with
two knurled screws.
NOTE: Your air cleaner is equipped with an air sensing
device. It may provide a short delay before the operating
light comes on.
IMPORTANT - Occasionally, you will hear a sharp
snapping sound (called arcing) coming from the air cleaner.
Arcing is a normal phenomenon. It can result from the
collection of especially large particles. It occursmore often
in e new installation. Later on, arcing may occur when the
cell has become loaded with dirt and needs washing, or
when still damp after washing. The presence (or absence) of
this sound normally does not mean that the unit is
defective.
