(1) First determine if the short is in the ionizing section
or the collecting section by connecting each high
voltage lead to its respective section, one at a time,
and energizing the power pack. (The lead not con-
nected must be supported away from any point of
contact.) The short symptoms will still exist for the
section in which the short is located. If the trouble
causing the short is bridging both sections, then the
short will be indicated in both sections when they
are individually connected.
(2) When the short is isolated to a cell tier, remove all
the cells within the tier and visually check the sec-
tions indicated to contain the short.
(a). If the short is in the ionizer section look for a
broken or defective insulator.
(b). If the short is in the collector section look for a
large piece of foreign material bridging the
collector plates or a defective insulator.
(c). If the short is indicated to be in both sections, it
will probably be a foreign object bridging the air gap
between the ionizer and the collector.
c. Open Circuits
Although open circuits can occur in the secondary they
usually take place in the primary. If the unit contains
only one power supply and the indicating light does not
glow the outage is probably one of the following. (1)
Supply line power to the control disconnected.
Reconnect.
(2) Open access door interlock in control of electronic
air cleaner. Be sure all access doors are properly closed
and secured.
(3) Outage in the power supply. Look for charred or
burned components or a loose wiring connection.
Replace power supply or reconnect wiring.
(4) Defective indicating light. Replace light.
d. Malfunctions other than short or open circuits. Refer
to trouble reference chart in this section.
8. Spare Parts
Recommended spare part quantities are usually based
on the unit size and the amount of units per installation.

be given to stocking the following components;
