Installation
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors 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.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06*-EN.
Shut Down Power
1. Using lockout/tagout safety procedures, shut down the
chiller's main power.
2. Open all starter and control panel disconnect switches
and secure them in the open position.
3. Confirm that the power is off to the control panel of the
chiller.
Vibration Mitigation - Line
Weights Kit for Oil Separator
Discharge Lines
The addition of an Adjustable Frequency Drive (AFD) on
RTHD chillers may result in vibration resonance at low
frequencies on the oil separator discharge line(s). Line
weights are added to mitigate this vibration.
