Voltage Configuration Instructions
ThermoFlex 900 and 1400 chillers equipped with the 115V 60Hz, 100v 50/60Hz Variable Voltage option and
ThermoFlex 900 to 5000 chillers equipped with 200-230V 50/60Hz Global Voltage option have a voltage
configuration panel located on the rear of the chiller behind an access panel, see Figure B-1.
• Use a 1/4” socket to remove the four screws securing the access panel to the chiller.
• The configuration panel has two 3-position toggle switches, one for voltage and one for frequency. All chillers
are shipped with the toggle switch in the center
SHIP
position. Place each switch to the settings that match
the voltage/frequency supplied to the chiller.
Note
For ThermoFlex900-2500 global voltage chillers, the compressor and fan will not operate when the
switch is in the
SHIP
position.
