Open the operation panel on the front of the remote controller, remove the two screws indicated in the right figure and then, re­move the front case of the remote controller.
NOTES
When installing the remote controller, remove the connector from the front case. The wires may break if the connector is not removed and the front case hangs down. When installing the front case, connect the connector to the front case.
When remote controller cord exposed
1) Make two horizontal or two vertical holes in the mounting surface (wall, etc.) to install the remote controller. (Fig. 2)
2) Use a tool to cut away the thin area on the upper center of the front case (indicated by
in Fig. 1).
3) Connect the remote controller cord to the remote controller terminal board specified in Fig. 2.
4) Wrap the connector and remote controller cords with vinyl tape or some other type of insulation as shown in Fig. 2.
5) Clamp the remote controller cord with the binder as shown in Fig. 2.
6) Cut off the excess binder.
7) Install the rear case to the wall, etc., with two screws (ø4 × 16). (Fig. 3)
NOTES
Step 4) will be noticed by customers, so do it with particular care.
