Start-up procedure
Pre-starting
Before starting the chiller, observe the
OptiView™ Control Center – Operation and Maintenance (Form
160.54-O1).
Ensure that the display reads
SYSTEM READY TO START
.
CAUTION
Vent any air from the chiller waterboxes prior to starting the water pumps. Failure to do so will result in
pass baffle damage.
Start-up
1. If the chilled water pump is manually operated, start the pump. The control center does not
allow the chiller to start unless chilled liquid flow is established through the unit. If the chilled
liquid pump is wired to the microcomputer control center, the pump starts automatically, and
this step is not necessary.
2. To start the chiller, press the COMPRESSOR START switch. This switch automatically spring
returns to the RUN position. If the unit was previously started, press the STOP/RESET side
of the COMPRESSOR switch and then press the START side of the switch to start the chiller.
When the start switch is energized, the control center is placed in an operating mode and any
malfunction is noted by messages on a graphic display.
