D) Replacing an Air Proving Switch (APS)
Before replacing the performance light, turn OFF
power to the air cleaner at the source.
1. Disconnect wiring from terminals 1, 2, 3, and 4 on the
APS. See Fig. 6.
2. Remove the circuit board from the studs by removing
the two nuts. Do not remove the spacers.
3. Install the new APS on the studs and secure with the
nuts. Ensure sensor protrudes only to the boom of the
plasc bushing.
4. Connect wiring to terminals on APS. Wiring from the
power switch is connected to terminals 2 and 3. Wiring
to the transformer is connected to terminals 1 and 4.
5. Test the new APS.
E) Removing Power Box
1. Turn the main system switch OFF or disconnect the
power cord.
2. Remove the power box cover.
3. If the unit does not have a cord, disconnect the source
wires to the air cleaner. Cap o the wires so the system
can sll be operated.
4. Remove the two nuts holding the power box to the
cabinet.
5. Slide the power box forward then up to remove it from
the cabinet.
6. If you are removing the power box for any length of
me, tape a cover over the top opening to prevent air
from entering into the system.
F) Replacing a Tungsten Ionizing Wire
Replacement wires are cut to the correct length and have
eyelets at each end for easy replacement.
1. Turn OFF power to air cleaner.
2. Remove cell from air cleaner.
3. Remove all parts of broken wire from the cell.
If necessary, the cell may be used temporarily with
one wire missing unl a replacement is received.
4. Place one end of the loop over the nger at the boom
of the cell.
5. Using needle-nose pliers, grip the other end of wire near
the boom of the top loop. Pull the wire up toward the
top nger. As you apply tension, the boom nger will
give, allowing the placement of the loop around the
top nger.
6. Install cell in air cleaner.
7. Return power to air cleaner.
8. Test cell for proper operaon.
