4-5. Attaching the receiver (for ceiling installation)
1. Prepare the ceiling for the receiver.
• Open a hole in the ceiling for the receiver. (Use paper pat-
tern printing (9)).
2. Wire the indoor unit and fix the lower part.
• Install the winged bar (10) to the lower part and fit the part
with the screws (8). Then, wire (field supplied) accordingly.
(Connect the P1 and P2 terminals on the rear of the lower
part to the P1 and P2 terminals on the indoor unit. The P1
and P2 terminals have no polarity.)
• Insert the lower part into the opening in the ceiling, first by
pressing the wings inward to fit the hole and then by
pushing from the screws (8) until it sits flat on the ceiling.
• Tighten the screws (8) until the lower part is fixed in place.
(Tighten both screws (8) evenly. Overtightening may
deform the case and possibly make it harder to install the
upper part.)
• Attach the upper part of receiver (1).
(Install the upper part on the lower part being careful
parts are facing in the correct direction. After installation,
turn on the power, and test emergency run button.)

Attaching the receiver (for wall mounting)
1. Wire the indoor unit.
(Connect the P1 and P2 terminals on the rear of the lower
part to the P1 and P2 terminals on the indoor unit.
Neither of the terminals is polarized, so it is not important if
connections are crossed.)
2. Fix the lower part.
• Install the lower part on the control box (field supplied part).
(Select as flat a place as possible to install the lower part.
Also, be aware of the fact that overtightening the screws (7)
may deform the case and possibly make it harder to install
the upper part.)
