3.When the unit connects to the engineering electric heating, connect the engineering power supply to the breaker.
4.The primary input voltage of transformer is defaulted at 230V(BK). When switching the power supply of the complete unit to 208V, connect the
primary input voltage of transformer to 208V(BU), which can be realized by exchanging the black wire and the blue wire.
5.① Only applicable for the unit whose motor is with earthing wire .
6.②As for wiring, please refer to the parameters before " /" of MCA and MOP of heat kit on the nameplate for CB1; please refer to parameters
