Indoor Unit
Refer to installation manual of indoor unit.
*1. Please follow applicable federal, state, or local codes to prevent potential leakage/electric shock. Or install a ground fault interrupt for the prevention of leakage and
electric shock.
IMPORTANT
If a current leakage breaker is used, it should be compatible with higher harmonics as this unit is equipped with an inverter. The use of an inadequate breaker
can cause the incorrect operation of inverter.
*2. Use copper supply wires. Use the electric wires over the rating voltage 300 V.
*3. Although the conduit size is larger than the size specified for the wire thickness according to UL standards, use a conduit size of 3/4 inch.
