c. Reassemble the filter assembly in accordance with the following instructions.
(1) Group the filter elements together, and align them with the holes in the bottom end cap (13) of the filter can-
ister.
(2) Press the grouped filter elements straight into the canister so that the terminals extend through the holes in
the end cap, keeping wires from buckling inside the tube (9).
(3) Connect the terminal ends of wires to the terminals of rectifier (8), being careful to match connections prop-
erly.
(4) Install top end cap (4) and new gasket (7) on
tube, with screw holes matching.
(5) Secure end cap with four (each) screws (6) and washers (5).
d. Re-install filter assembly as follows:
(1) Position the filter assembly on
the junction box (22, figure 4-3) drawing the wires into the junction box through
the four access holes.
(2) Secure the filter assembly, to the junction box with four screws, washers and lock washers.
(3) Connect wires, previously tagged for identification, to the appropriate components.
e.
Install the cover (3, figure 4-3) on
the junction box, and secure it
with four panel fastener screws (1).
f.
Position the front access panel (figure 1-1) on
the air conditioner, and secure it
with four panel fastener screws.
Test each filter element for continuity, using an ohmmeter or continuity tester. Continuity should be indicated. An alter-
native method of isolating a bad filter element is to substitute a filter element known to be good for each element in turn
until interference is located and eliminated, since the continuity test is not conclusive for capacitors under load.
