5. Protect the system from damage during shutdown periods.
6. Maintain the set point, time schedules, and other PIC functions.
Prepare the Machine for Start-Up
Follow the steps described in the Initial Start-Up section.
To Start the Machine
1. Start the water pumps, if they are not automatic.
2. On the LID default screen, press the LOCAL or CCN softkey to start the system. If the
machine is in the OCCUPIED mode, and the start timers have expired, the start sequence
will start. Follow the procedure described in the Start-Up/Shutdown/Recycle section.
Check the Running System
After the compressor starts, the operator should monitor the LID display and observe the
parameters for normal operating conditions:
1. The oil reservoir temperature should be above 140 F (60 C) during shutdown, and above
100 F (38 C) during compressor operation.
2. The bearing oil temperature accessed on the Status01 table should be 120 to 165 F (49 to
74 C). If the bearing temperature reads more than 180 F (83 C) with the oil pump running,
stop the machine and determine the cause of the high temperature. Do not restart the
machine until corrected.
