2.4.3 Optional Equipment (Field Installed)
NOTE
Do not mount any optional equipment on the
unit access doors.
2.4.3.1 Remote Display
As a standard the controller is factory installed and
wired to the
FLAiR precision A/C unit. As an option,
the controller may be mounted remotely. For mounting
and wiring instructions, refer to the system drawings
and supplemental manual sent in the data package
with your unit.
2.4.3.2 Condensate Pump
An optional, factory installed condensate pump may be
provided. The pump automatically eliminates conden-
sate and humidifier flush water from the drain pan. The
condensate pump is typically installed by the factory
inside the A/C unit cabinet. If an optional, field installed
condensate pump is selected, it should be located as
near as possible to the air conditioning system. The
pump should be positioned so the inlet hole in the
pump is below the drain pan inside the A/C unit. The
pump includes a mounting bracket with two holes to
secure it in place. Ensure that the pump is level for
proper operation.
2.4.3.3 Remote Temperature/Humidity Sensor
The remote temperature/humidity sensor must be
located so that it will properly sense the temperature/
humidity conditions to be controlled. The sensor
should not be mounted near a doorway or an area
where it would be exposed to direct sunlight. Follow
the steps below to mount the sensor. Refer to section
2.7, Utility Connections and the wiring diagram
supplied with your unit for wiring details.
1. Using a flat head screwdriver, remove the cover
plate from the base of the sensor.
2. Place the base temporarily over the wire hole
opening in the wall. Level the base and mark the
mounting hole locations through the two slots.
3. Drill the mounting holes and insert the wall
anchors provided.
4. Run the wires coming out of the wall through the
opening in the base, then secure the base with the
screws provided.
5. Make the wiring connections. See Section 2.7,
Utility Connections.
6. Replace the cover plate on the base.
CAUTION
Take care not to damage the exposed tempera-
ture/humidity sensors on the PC board while
screwing in the cover fastening screw. The sen-
sors can be damaged if handled improperly.
2.4.3.4 Remote Water Detector
The remote water detector is normally placed on the
floor or in a field supplied auxiliary drain pan located
beneath the unit. SATS provides 2 types of water
detectors:
Spot type water detector-
Remove the protective cover and connect two control
wires to the terminals on the base, (terminal lugs are
provided). The base is provided with a
mounting hole in the center which may
be used to secure the water detector in
place. Replace the cover and place the
water detector(s) on the floor with the
metal electrodes facing downwards.
When water is present, current will flow between the
electrodes.
NOTE
Do not place the spot type water detector on
an electrically conductive surface.
Cable type water detector-
Lay the cable water detector flat across the floor where
water could collect. When water is present,
current will flow between
the two wires. A two
conductor wire harness is
provided with a quick
connect fitting on the
end. The harness mates to the fitting on the cable water
detector and interconnects it to the control board located
inside the electric box.
