10.6. Installing the wireless sensor (Fig. 10-10)
• Pull out the wireless sensor cable from the square hole in the corner panel of the
refrigerant piping section of the main unit.
• Feed the cable through the electric component box of the main unit as shown in the
illustration, and then connect it to CN90 on the control board. Adjust the length of
the cable so the corner panel can be removed, and then secure the cable with the
clamp.
10.7. Check
• Make sure that there is no gap between the unit and the grille, or between the grille
and the surface of the ceiling. If there is any gap between the unit and the grille, or
between the grille and the surface of the ceiling, it may cause dew to collect.
• Make sure that the wires have been securely connected.
