Warnings and Cautions

Warnings and cautions appear at appropriate sections throughout this manual. Read these carefully.

WARNING

Indicates a potentially hazardous situation, which could result in death or serious injury if not avoided.

CAUTION

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

CAUTION

Indicates a situation that may result in equipment or property-damage-only accidents.

CAUTION

Use copper conductors only! Unit terminals are not designed to accept other types of 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

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.

Note: Do not release refrigerant to the atmosphere!

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.
