NOTE National Electric Code Wiring
All wiring must be provided in accordance with the National Electrical Code and local code requirements
for Class 2 circuits.
2.7.6 Optional Equipment
2.7.6.1 Condensate Pump
Systems supplied with a field installed condensate pump require power and control field wiring. The control
wires from the terminal board in the electric box should be run through the overflow switch in the condensate
pump housing.
After installing the condensate pump, connect two power conductors from the condensate pump main power
terminals to the air conditioning unit and a ground wire 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 is provided with pigtail leads for splice-type wire connections with twist-on
connectors (wire caps). Refer to the supplied electrical drawing for proper wire terminations.
2.7.6.2 Humidistat/Dehumidistat
The humidistat/dehumidistat are mounted in the same manner but are wired differently. The humidistat/
dehumidistat both require two conductors for connection to the air conditioning system. The controls have
pigtail leads for splice type wire connections with twist on connectors (wire caps). Refer to the supplied
electrical schematic for proper wire terminations.
2.7.6.3 Remote Water Detector
There are two types of water detector available with OHS units: Spot type and strip/cable type.
Spot Type. A remote spot type water detector requires three conductors to be wired to the control terminal
board in the unit electric box. The wire insulation must be rated at 600 V. The water detector has pig-tail leads
for splice type wire connections with twist on connectors (wire caps). Refer to the supplied electrical drawing
for proper wire terminations.
Strip/Cable Type. A remote strip/cable type water detector is provided with a two conductor cable harness
with a quick connect fitting on the end. The harness mates to the fitting on the water detector and connects
it to the control board inside the electric box. Refer to the electrical drawing supplied with your unit for proper
wire terminations.
CAUTION
Do not allow the cable water detector to contact metal (frame or condensate pan). It must be mounted on
the plastic stand-offs provided with the water detector.
2.7.6.4 Remote Temperature Sensor (ATech)
The remote temperature sensor requires a three-conductor shielded cable with the shield terminated at the
thermostat. Both the thermostat and the sensor are provided with a terminal strip with box type lugs for wire
connections. Refer to the electrical drawing supplied for proper wire terminations.
