1. Trending variables instantaneous values according
to cursor position. Current cursor timestamps are
displayed as well.
2. Text box to select viewing time span. It's used for
zooming in on trends time axis. Options for
selection:
3. Maximum and Minimum thresholds for trends
viewing. Used for zooming in on trends variables
axis. Both Maximum and Minimum thresholds are
adjustable via respective numeric boxes. Default
Min / Max values: –10.0 / 160.0. 'Default Span'
button is used to revert to defaults, so as to reset
longitudinal zooming.
4. "Scroll to Time" button is used to return to real
time viewing.
5. Cursor positioning buttons.
6.
Buttons used to scroll back and forth in time. They
implement time axis trends pages scrolling.
7. Buttons used to scroll back and forth in time. High
resolution time axis scrolling.
8. Button is used to pause / resume real-time trending.
Operator Tasks
Before operating the unit, ensure that all compressor
refrigeration service valves are fully back-seated
counterclockwise.

I I m m p p o o r r t t a a n n t t : : This start-up procedure is not to be used for
the first-time initial startup for a newly
installed chiller. See Preparation for Initial
Startup in the Installation section of this
manual for instructions regarding that
situation.
1. De-energize the chiller using standard lockout/
tagout procedures.
2. Using a known operational voltage meter, test and
confirm the chiller is de-energized before
proceeding further.
3. Inspect power distribution fuses and overload
settings to verify they are correct.
4. Verify that the oil level is correct in each
compressor using the compressor sight glass.
N N o o t t e e : : See recommended inspection interval in the
maintenance section of this manual.

5. Verify that pressure and temperature switches are
closed.
6. Restore power to all modules.
7. Inspect refrigerant pressures for each module using
the touchscreen interface panel.
8. Verify that pressure switches and thermostats have
the correct cut-in and cut-out settings using the
touchscreen interface panel.
9. Verify chiller water flow to condenser and
evaporator.
10. Monitor and record temperature and refrigerant
pressures registering on the touchscreen interface
panel.
