(6) If filter does not meet continuity requirements, replace it.
NOTE
Continuity testing does not necessarily predict the behavior of capacitors under load. If the
filter still does not operate properly after passing the continuity test, substitute a filter
known to be good.
c. Installation
(1) Using screwdriver, secure filter to mounting plate with six screws.
(2) Connect P10 plug and harness to J10 connector on filter.
(3) Connect P11 plug and harness to J11 connector on filter.

This junction box is the protective enclosure that contains the compressor circuit breaker (CB1), relays (K1, K2,
and K4), time delay relay (K3), fuses (F1, F2 and F3), rectifier (CR1), and terminal blocks (TB1 and TB2). The
transformer is mounted on the outside top of the box. See the following paragraphs for maintenance of junction
box parts.
