2.7.3 Optional Equipment

NOTE

All customer provided wiring must be in accor-

dance with local and national electrical code re-

quirements for Class 2 circuits.

2.7.3.1 Condensate Pump

Systems supplied with a field installed condensate

pump will require power and control wiring to be

connected to the unit. The control wires from the

terminal board in the electric box should be run

through the overflow switch in the condensate pump

housing. After proper installation of the condensate

pump, the installer must connect two power conduc-

tors from the condensate pump main power terminals

to the air conditioning unit. A ground wire must be

connected to the unit ground stud located within the

unit electric box. Two control conductors must be

wired to the control terminal board located within the

unit electric box. The condensate pump provides

pigtail leads for splice type wire connections with twist

on connectors (wire caps). Refer to the supplied

electrical diagram for proper wire terminations.

2.7.3.2 Remote Temperature Sensor

(See Figures 7 and 8)

The remote temperature sensor requires a three

conductor shielded cable with the shield being termi-

nated at the thermostat. The shield is terminated at

the RS2 thermostat terminal. Both the thermostat and

the sensor provide a terminal strip with box type lugs

for wire connections. Refer to the electrical diagram

supplied for proper wire terminations.
