5. Simplified Remote Controller
1. Insert a screwdriver or the like in the groove on the lower
side of the simplified remote controller body to pry off the
back case. (Fig. 3-38)
2. Use the 2 supplied M4 or 5/32" machine screws to secure
the simplified remote controller back case. Prior to mount-
ing, clear the cutouts in the back case corresponding to
the holes in the wall box using a screwdriver or the like.
Use the spacers and take care not to tighten the screws
excessively. If the back case will not seat well, cut the
spacers to a suitable thickness.
3. Connect locally supplied 3 core lead wires to the lead
wires from the simplified remote controller. (See “How to
wire the simplified remote controller.”)
When connecting the locally supplied 3 core lead
wires to the terminal block, check the terminal num-
bers in the indoor unit to make sure that the wires are
correctly connected. (Fig. 3-39)
(The simplified remote controller is damaged if 208 /
230 AC is applied.)
4. Fit the simplified remote controller to the tabs of the back
case and mount it.
