box and the sensor are provided with a terminal strip
for the wire connections. Refer to the supplied electri-
cal schematic for proper wire terminations.
2.7.3.2 Remote Water Detector
The optional remote water detector requires two
conductors to be wired to the control terminal board
within the unit electrical box. The wire insulation must
be rated at 600V. The water detector includes screw
type terminals for wire connections. Refer to the
supplied electrical schematic for proper wire termina-
tions.

System Settings and Adjustments
2.8.1
Chilled Water Circuit
In a chilled water A/C unit, cooling is maintained by
the liquid flowing through a regulating valve on the
outlet of the cooling coil. The regulating valve propor-
tionally opens to increase liquid flow as the tempera-
ture rises (or closes as the temperature falls). If the
unit is turned off, the valve will return to the closed
position, shutting off liquid flow to the coil. Chilled
Water regulating valves are available in 2-way or 3-way
configurations. Refer to the piping drawing supplied
with your unit to determine which type valve is pro-
vided.
Location and size of chilled water valves differs with
the size of the A/C unit. The chilled water regulating
valves are factory set for the correct operation and
should not require field adjustment.
2.8.2 Humidifier Adjustment
The humidifier has a capacity adjustment pot on the
humidifier control circuit board. The capacity pot may
need to be field adjusted if the humidifier is not supply-
ing enough capacity for current room conditions.
It is recommended that if the humidifier capacity pot
requires adjustment, the adjustment is made in small
increments and verified. Refer to the humidifier manual
sent with your unit for the capacity pot location.
CAUTION
Adjusting the capacity pot too high may result in
condensation within the system.
