50TC*D/E units for installation in the United States contain use of Carrier's Staged Air Volume (SAV™) 2-speed
indoor fan control system. This complies with the U.S. Department of Energy (DOE) efficiency standard of 2018.
50TC*D/E units for installation outside the United States may or may not contain Carrier's Staged Air Volume
(SAV) 2-speed indoor fan control system as they are not required to comply with the U.S. Department of
Energy (DOE) 2018 mandatory efficiency standard.
50TC*M units for installation inside or outside the United States do not contain use of Carrier's Staged Air
Volume (SAV) 2-speed indoor fan motor control system as they comply with the U.S. Department of Energy
(DOE) 2018 mandatory efficiency standard without their use.
For specific details on operation of the Carrier SAV 2-speed indoor fan system, refer to the Variable Frequency
Drive (VFD) Factory-Installed Option 2-Speed Motor Control Installation, Setup, and Troubleshooting manual.

SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be
hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install, re-
pair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions
of cleaning coils and filters and replacing filters. All other op-
erations should be performed by trained service personnel.
