Electrical Wiring
The electrical work should be performed by a specialist qualified for the work.
• Use the single phase power supply, and be sure to install the sub power distributing board for
exclusive use with the unit(separately purchased by the user).
• Avoid octopus-type wiring as it can cause a drop in voltage, thus resulting in poor performance of
the automatic control circ u i t .
• Be sure to install the earth leakage circuit breaker (separately purchased by the user).
• Be sure to connect the grounding wire .
• When connecting the connecting wire between the indoor and outdoor unit, be sure to align the
terminal block number with the connecting wire number.
• When the connecting wire is not properly connected, it may cause tro u b l e .
Be careful not to allow connecting wires and power lines to get in contact with service valve or the
pipe without an insulator.
1 . Connect it to the terminal board N and L for power supply to the outdoor unit.
In so doing, peel off the end of the power cord by about 5mm, and press the cord to the ring ter-
minal for hooking.
2 . Perform the power grounding using the screw for exclusive use with the outdoor unit.
