NOTES :
• To avoid malfunction of the remote controller, do not assemble or run remote control wiring together
with the power cables, and do not enclose them in the same metal conduit.
• When the power unit induces electrical noise, it is recommended that a noise filter or the like be
installed.
How to install the receiver unit
For flush mounting into a wall, install the separate receiver unit in a metal switch box (field
supply) that has been recessed into the wall in advance.
1. Insert a flathead screwdriver or similar tool
into the notch, and remove the face plate.
2. Fix the receiver unit with 2 M4 screws pro-
vided. Do not overly tighten, and use the pro-
vided spacers. If the receiver unit does not fit
in the wall, cut spacers to adjust the clear-
ance.
3. Connect the receiver unit wiring (2-core cable)
with the cables extended from the indoor unit.
(Refer to the section on receiver unit wiring.)
Be sure to determine the correct terminal
numbers on the indoor unit when wiring the
receiver unit. The remote controller will be
damaged if high voltage (such as 200 VAC) is
applied.
4. Reinstall the face plate.
