To prevent possible damage to the chiller and/or the control circuit and the warranty becoming void, only
the following settings and parameters should be applied.
DIP switches must be checked and set before applying control circuit power for the settings to be
applicable. With the exception of the chilled water settings, changing the DIP switch settings with the
control circuit power on will have no effect on the unit operation.
