CV = constant volume CW = clockwise

CCW = counterclockwise E/A = exhaust air

F/A = fresh air

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 = sngle-zone (unit airflow) VAV = variable air volume

Note: One copy of this manual ships inside the control panel of each unit.

It is important that you perform periodic maintenance to help ensure trouble free operation. Should equipment failure occur, contact a qualifiedTrane service organization for an experienced HVAC technician to properly diagnose and repair this equipment.

Sample Warnings and Cautions

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.

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 refrigerant for continued use and follow all warnings and cautions in this manual.
