4 Wiring
a) Connect the blue connector of the 2-wire cord
to CNP on the noise filter board inside the
control box.
b) Insert the white connector of the 2-wire cord
into CN4F on the indoor P.C. board.
Since a connector has been inserted into both
CNP and CN4F before shipment, they must
be removed.
c) When wiring is complete, fasten the remaining
cords with the band (small) 3.

a) Pass the 2-wire cord (with a blue connector) through the hole
shown in the photo.
b) Pass the 2-wire cord (with a white connector) through the pipe
sensor and LEV lead wire hole.
When fastening lead wires
Power wires and low-voltage wires are separately bundled inside the control box to reduce noise interference. Lead wires
from the Drain Water Lift-Up Kit also need to be bundled separately. Follow the steps below to hold them and the lead
wires inside the control box together.
(1) Power wires
* Feed the lead wires from the drain pump through the wire saddle as shown with "A" in Photo 4-2.
* Bundle the excess lead wires from the drain pump, and clip them together with a cable clip as shown in Photo 4-3.
(2) Low voltage wires
* Bundle the excess lead wires from the float switch, then keep them, pipe sensor lead wires, and LEV lead wires
together with a band (small) 3 as shown in Photo 4-4.
