flowing through its internal tubes in order to remove heat from the refrigerant.

Motor-Compressor

This component maintains system temperature/pressure differences and moves the heat carrying refrigerant from the cooler to the condenser.

Control Center

The control center is the user interface for controlling the machine. It regulates the machine’s capacity as required to maintain proper leaving chilled water temperature. The control center:

registers cooler, condenser, and lubricating system pressures

shows machine operating condition and alarm shutdown conditions

records the total machine operating hours

sequences machine start, stop, and recycle under microprocessor control

provides access to other CCN (Carrier Comfort Network) devices

Factory-Mounted Starter (Optional)

The starter allows for the proper starting and disconnecting of the electrical energy for the compressor-motor, oil pump, oil heater, and control panels.

Storage Vessel (Optional)

There are 2 sizes of storage vessels available. The vessels have double relief valves, a magnetically coupled dial-type refrigerant level gage, a one-inch FPT drain valve, and a 1/2-in. male flare vapor connection for the pumpout unit. A 30-in.-0-400 psi (–101- 0-2750 kPa) gage
