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 or
tensile force. (PG connection or the like.) Connect transmission
wiring to transmission terminal block through the knockout hole of
control box using ordinary bushing.
After wiring is complete, make sure again that there is no tension on
the connections, and attach the cover onto the control box in the
reverse order removal. Also, seal any openings created from wiring
into the air handler. This will prevent air leakage.
Caution:
Wire the power supply so that no tension is imparted. Otherwise
disconnection, heating or fire may result.
Important:
Attach shielding ground on the outdoor unit's ground terminal.
Specifications are subject to change without notice.
If the remote controller cable exceeds 10 m [32 ft], use a 1.25 mm
[AWG16] diameter cable over the exceeded portion, and add that
exceeded position to within 200 m [656 ft].

Connect the conduit to the air handler cabinet using a 1/2" connector.
Ensure there is no air leak and seal properly if required.
On the line voltage terminal block loosen the screws marked L1, L2
and G on the line voltage terminal strip. Insert line voltage wires and
tighten screws.

Changing the power voltage setting
(Be sure to operate with the main power turned OFF.)
Please set the switch SW5 according to the power voltage.
-Set SW5 to 240V side when the power supply is 230 volts
-When the power supply is 208 volts, set SW5 to 220V side.
