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, repair, or
service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of
cleaning coils and filters and replacing filters. All other operations
should be performed by trained service personnel. When working
on air-conditioning equipment, observe precautions in the litera-
ture, tags and labels attached to the unit, and other safety precau-
tions that may apply.
48TC 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.
48TC units for installation outside the United States may or may not contain use of the SAV 2-speed
indoor fan control system as they are not required to comply with the U.S. Department of Energy
(DOE) efficiency standard of 2018.
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.
