2 − Dual Capacitor C12
The compressor (scroll or reciprocating) and fan in
single-phase units use permanent split capacitor motors. The
capacitor is located inside the unit control box (see figure 4 and
5). A single dual" capacitor (C12) is used for both the fan
motor and the compressor (see unit wiring diagram). The fan
side and the compressor side of the capacitor have different
MFD ratings. See table 1 for dual capacitor ratings.
