(1) Loosen the screw 2, then remove the screw 1 (※1).
(※1): The screw positions may differ depending on models.
(2) Install the CO
(※2): Be careful not to get the damper wire or indoor thermistor wire caught in the sensor.
For VAM150H(S), VAM250H(S), VAM150HS, and VAM250HS,
the humidity sensor (indoor side) is installed nearby.
If the CO
2
cannot be installed in the correct position so install the CO
as shown in the figure on the right.

3. Wiring connection of CO
(1) Remove the 2 fixing screws of the electrical box, then open the electrical box.
(2) Bring out the wire from the inside of the unit through the lower bush (weak elec. wire side),
then firmly insert it to the X14A connector (white) on the print circuit board A1P. (See Arrow View A)
(3) Bundle the CO
so that there is no stack (※1, See Arrow View B).
(4) Bundle the excess wires and secure them with the clamp inside the electrical box. (See Arrow View A)
(5) Close the electrical box and tighten the 2 fixing screws on the electrical box, be careful not to get any wire caught by the screws.
(6) After binding, cut off the excess edge of the clamp.
