2. Attach the 2 pin connectors (FM1, CH1 and FM2, CH) to the correct (Zone One or Two) mating connectors at the back
of the condensing unit ( ( D D e e t t a a i i l l A A ) ) .
3. Route each harness to the terminal block of the correct (Zone One or Two) evaporator.
a. Cut wires (HGS, SLS, LLS, FM1, FM2, SC, DH, CH1 and CH) to length, strip 7 mm (0.25 in.) from ends and attach
ring terminals onto CH1 and CH wires and forked terminals on all others.
b. Connect wires (HGS, SLS, LLS, DH, FM1, FM2, and SC) to each terminal block ( ( D D e e t t a a i i l l B B ) ) .
c. Connect wires (CH1 and CH) to the ground stud of each evaporator ( ( D D e e t t a a i i l l B B ) ) .

C C ) ) .
a. Coil Temperature Sensor (CTN, CTP)
b. Discharge Air Temperature Sensor (DTN, DTP)
c. Return Air Temperature Sensor (RTN, RTP)
I I m m p p o o r r t t a a n n t t : : The gold terminal pins supplied in the installation kit must be used if the sensor harnesses are cut to
