CAUTION Prevent remote cord chips from getting into the remote controller. Electric shock or malfunction may result.
6. Wiring hole for installing directly on the wall (or open wiring)
• Cut off the shaded area from the upper cover using a knife, nippers, etc.
• Take out the remote control cord connected to the terminal block via this portion.
7. Install the cover to the remote controller.
To remove the cover, insert a minus
screwdriver into one of the open
slots, and move it in the direction of
the arrow shown in the figure.
First, hook the cover to the two upper claws and then fit it to the remote controller.
CAUTION Press the cover until it snaps shut. If not, it may fall off. CAUTION Do not turn into the screwdriver in the slot. Doing so may damage the slot.
NOTE: A protection sheet is stuck to the operation section. Peel off this protection sheet before use.
