Unit terminals are not designed to accept other type conductors. Failure to use copper conductors may result in equipment damage.

Common HVAC Acronyms

For convenience, a number of acronyms and abbreviations are used throughout this manual. These acronyms are alphabetically listed and defined below. CFM = Cubic-feet-per-minute

CKT. = Circuit

CV = Constant volume CW = Clockwise

CCW = Counterclockwise E/A = Exhaust air

F/A = Fresh air

HGBP = Hot gas bypass

HVAC = Heating, ventilation and air conditioning

IGV = Inlet guide vanes I/O = Inputs/outputs

IOM= Installation/operation/maintenance manual

LH = Left-hand O/A = Outside air

psig = Pounds-per-square-inch, gauge pressure

R/A = Return air RH = Right-hand

RPM = Revolutions-per-minute S/A = Supply air

SZ = Single-zone (unit airflow) VAV = Variable air volume w.c. = Water column

Special Note on Refrigeration Emissions

World environmental scientists have concluded that ozone in our upper atmosphere is being reduced due to the release of CFC fully halogenated compounds.

Trane urges all HVAC service personnel to make every effort to prevent any refrigerant emissions while installing, operating, or servicing equipment. Always conserve refrigerants for continued use.
