    Under normal operation, the chiller will maintain a constant leaving fluid temperature approximately equal to the chilled fluid set point. As the cooler load varies, the entering cooler fluid will change in proportion to the load as shown in Fig. 20. Usually the chiller size and leaving-fluid temperature set point are selected based on a full-load condition.

    CAUTION Brine duty application (below 40 F [4.4 C] LCWT) for chiller normally requires factory modification. Contact your Carrier representative for applicable LCWT range for standard water-cooled chiller in a specific application. VOLTAGE — ALL UNITS Main Power Supply — Minimum and maximum acceptable supply voltages are listed in the Installation Instructions.

    circuits, the control will most often start the A1 or B1 compres- sor first, especially after long off periods. The MBB controls fan stages to maintain the head pressure set point and will auto- matically adjust unit capacity as required to keep compressors from operating outside of the specified envelope.

    Failure to provide the proper anti- freeze solution mixture is considered abuse and may impair or otherwise negatively impact the Carrier warranty. The main base board (MBB) monitors leaving fluid temper- ature at all times. The MBB will rapidly remove stages of ca- pacity as necessary to prevent freezing conditions due to the rapid loss of load or low cooler fluid flow.
