wire the remote control cable in it. Then, connect the ground wire with the box and the tube.
(D)Install a noise filter when the power supply emits harmful noises.
● To avoid any corrosive action to the heat exchanger , do not install the indoor unit in an acid or
alkaline environment. In an application where the indoor unit is to be utilized under such
