4.4 Installation
1. First select an installation position. According to the size of the communication line of the
wire controller, leave a recess or a embedded wire hole to bury the communication line.
2. If the communication line between the wire controller (85×85×20) and the indoor unit is
surface-mounted, use 1# PVC pipe and make matching recess in the wall (refer to Figure 6);
If concealed installation is adopted, 1# PVC pipe can be used (Refer to Figure 7).
3. No matter if surface mounting or concealed mounting is selected, it is required to drill 2 holes
(in the same level) which distance shall be the same as the distance (60mm) of installation
holes in the bottom plate of the wire controller. Then insert a wood plug into each hole. Fix
the bottom plate of the wire controller to the wall by using the two holes. Plug the
communication line onto the control panel. Lastly install the panel of the wire controller.
Caution:
During the installation of the bottom plate of the wire controller, pay attention to the direction
of the bottom plate. The plate’s side with two notches must be at the lower position, and otherwise
the panel of the wire controller cannot be correctly installed.
