 CAUTION
•  While connecting the wires, please strictly follow the wiring diagram.  
•  The refrigerant circuit can become very hot. Keep the interconnection cable away from 
the copper tube.  
5. Clamp down cable with the designated cable clamp to secure it in place. The cable should not be 
loose, and should not pull on the u-lugs.  
6. Reinstall the electric box cover and the front panel of the indoor unit.
