6. Secure the base to the drywall anchors using the #6 × 1"
mounting screws provided.
7. Screw the plate firmly to the wall so the foam plate backing
is compressed about 50%.
8. Terminate the unit according to the guidelines in the
Termination section.
9. Attach cover by latching it to the top of the base, rotating it
down and snapping it into place.
10. Secure the cover by backing out the lock-down screws
using a 1/16" Allen wrench until it is flush with the sides of
the cover
Note: in any wall-mount application, the wall temperature
and the temperature of the air within the wall cavity can
cause erroneous readings.
The mixing of room air and air from within the wall
cavity can lead to condensation, erroneous readings
and sensor failure. To prevent these conditions, Daikin
recommends sealing the conduit leading to the junction
box with fiberglass.
Maintenance
Wipe the display as needed with a damp water only cotton
cloth. Do not use any type of cleaner as it may damage the
buttons or scratch the display. Do not paint.
Terminations
Daikin Applied recommends using shielded 22AWG for all
connections and a separate twisted pair for the power wire
connections. The shield should be earth grounded only at the
power source. Larger gauge wire may be required for runs
greater than 250'.

Figure 111: Sensor Circuit Board
The AC power wiring at terminals [R] & [5] should be run in a
separate twisted shielded pair to avoid fluctuating and inaccurate
signal levels induced into the other sensor signal wires.
This sensor AC power can be run in the same conduit with the
sensor signal wire as long as it's run in twisted, shielded pair and
terminated properly.
All wiring must comply with the National Electric Code (NEC)
and local codes. Do NOT run any of this device's wiring in the
same conduit as other AC power wiring. Tests show that fluctu-
ating and inaccurate signal levels are possible when AC power
wiring is present in the same conduit as the signal lines. If you
are experiencing any of these difficulties, please contact your
Daikin representative.
