NOTES: All CCAR/CAUJ applications require that the CCAR Compressor Chiller control the condenser
ambient dampers (when applicable).
For Ambient Control Dampers when applicable - One shielded pair for each damper assembly
must be run from the CCAR Compressor Chiller to the CAUJ condenser.
CCAR units are designed for operation down to a minimum of 40°F ambient.
