Installation
The "ABC" indicator on the face of the phase indicator will glow if phase is ABC for terminals L1, L2, L3.
IMPORTANT! After completion of wiring, check all electrical connections, and ensure all connections are tight. Replace and secure all electrical box covers and access doors before leaving unit or connecting power to circuit supplying the unit.
CAUTION! Units with scroll compressors are not equipped with crankcase heaters.
WARNING! Disconnect all power, including remote disconnects, and discharge all capacitors before servicing.
Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. After power is removed, allow
4 minutes for capacitors to discharge. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and/or discharge capacitors before servicing could result in death or serious injury. For additional information regarding the safe discharge of capacitors, see Trane Service Bulletin
