Voltage Limitations
The following voltage limitations are absolute and
operation beyond these limitations may cause serious
damage to the compressor.
Excessive flow will cause damage to
the cooler. Do not exceed maximum
cooler flow. Special care should be
taken when multiple chillers are fed
by a single pump.
NOTES:
1. For leaving brine temperature below 40°F (4.4°C), contact your nearest Johnson Controls Office for application requirements.
2. For leaving water temperature higher than 55°F (12.8°C), contact the nearest Johnson Controls Office for application guidelines.
3. The evaporator is protected against freezing to -20°F (-28.8°C) with an electric heater as standard.
4. For operation at temperatures below 25°F (-3.9°C), the optional Low Ambient Kit will need to be installed on the system.
5. For operation at temperatures above 115°F (46.1°C), the optional High Ambient Kit will need to be installed on the system.
