through the wiring guide in through the back of the indoor unit and to the front.
(8) Connect the piping. (See “5.REFRIGERANT PIPING WORK” and Fig. 10)
• To avoid the influence of noise from the power supply line on the transmission wiring and the remote
controller wiring, these wirings must be kept as far as possible from the power/ground wirings. As shown in the
figure, keep the power supply wiring and the ground wiring together. Keep the transmission and remote con-
troller wirings together and route them maintaining a good distance from the power supply/ground wirings
(that is, on the other side of the power supply/ground wirings). Then, fix them securely on the refrigerant pipe.
• Seal the piping through-hole with putty corking material.
