Use the checklist provided below in conjunction with the “General Unit Requirements” checklist to ensure that the unit is properly installed and ready for operation.

￿WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

Check all electrical connections for tightness and “point of termination” accuracy.

Verify that the condenser airflow will be unobstructed.

Verify that the condenser fan and indoor blower turn freely without rubbing and are properly tightened on the shafts.
