Pre-Startup Checklist

Once the M-Series Climate Changer air handler has been assembled and installed, attention must
be directed to individual components for proper operation. Before operating the unit, complete the
pre-startup checklist.
Hazardous Voltage with Capacitors!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power cannot be inadvertently energized. For variable
frequency drives or other energy storing components provided by Trane or others, refer to the
appropriate manufacturer's literature for allowable waiting periods for discharge of capacitors.
Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect
power and discharge capacitors before servicing could result in death or serious injury.
Note: For additional information regarding the safe discharge of capacitors, see
