*For applications requiring cooler leaving water temperature operation at less than
40 F (4.4 C), the units require the use of antifreeze and application may require
the brine option. Contact your local Carrier representative for more information.
†For applications requiring cooler entering water temperature operation at less
than 45 F (7.2 C), contact your local Carrier representative for unit selection using
the Carrier electronic catalog.

NOTES:
1. The 30XA units will start and pull down with loop temperatures up to 95 F (35 C).
2. Nominal flow rates required at AHRI conditions 44 F (7 C) leaving fluid tempera-
ture, 54 F (12 C) entering water temperature, 95 F (35 C) ambient. Fouling factor
0.00010 ft 2 -hr-F/Btu (0.000018 m
3. To obtain proper temperature control, cooler loop fluid volume must be at least
3 gal/ton (3.23 L/kW) of chiller nominal capacity for air conditioning and at least
6 gal/ton (6.5 L/kW) for process applications or systems that must operate in low
ambient temperatures (below 32 F [0° C]).
