Backup operation
Even when the electrical work has not been completed, the fan and the drain
pump can be operated by connecting the jumper (SWE) on the control board
to the ON-side and energizing the terminal block.

Reconnect the SWE on the control board to the OFF-side upon completion of
all work.
9.2. Connecting remote controller, indoor
and outdoor transmission cables
(Remote contoroller is optionally available.)
•
Connect indoor unit TB5 and outdoor unit TB3. (Non-polarized 2-wire)
The “S” on indoor unit TB5 is a shielding wire connection. For specifications
about the connecting cables, refer to the outdoor unit installation manual.
•
Install a remote controller following the manual supplied with the remote con-
troller.
•
Connect the “1” and “2” on indoor unit TB15 to a MA remote controller. (Non-
polarized 2-wire)
•
Connect the “M1” and “M2” on indoor unit TB5 to a M-NET remote controller.
(Non-polarized 2-wire)
•
Connect the remote controller’s transmission cable within 10 m using a 0.75 mm
2
core cable. If the distance is more than 10 m, use a 1.25 mm
2
junction cable.

The MA remote controller and the M-NET remote controller cannot be used at
the same time or interchangeably.
Note:
Ensure that the wiring is not pinched when fitting the terminal box cover.
Pinching the wiring may cut it.
Caution:
Install wiring so that it is not tight and under tension. Wiring under tension
may break, or overheat and burn.
•
Fix power source wiring to control box by using buffer bushing for tensile force.
(PG connection or the like.) Connect transmission wiring to transmission ter-
minal block through the knockout hole of control box using ordinary bushing.
•
After wiring is complete, make sure again that there is no slack on the connec-
tions, and attach the cover onto the control box in the reverse order removal.
Caution:
Wire the power supply so that no tension is imparted. Otherwise disconnec-
tion, heating or fire result.
9.3. Connecting electrical connections
Verify that the model name on the operating instructions on the cover of the control
box is the same as the model name on the nameplate.
Step 1
Remove the screws holding the terminal box cover in place.

9.4. Selecting the static pressure
Type 80 · 140
The external static pressure can be changed over as required. For the selection of
the static pressure, insert an attachment between the connector of the motor lead
wire and the control box.
The relationship among the attachment, voltage and the external static pressure is
shown below.
