Appendix C: CenTraVac™ Chiller Start-Up Tasks to be
Performed by Trane
WARNING
Safety Alert!
Failure to follow instructions below could result in
death or serious injury.
In addition to the following tasks, you MUST:
•
Follow all instructions in the unit's Installation,
Operation, and Maintenance manual, including
warnings, cautions, and notices.
•
Perform all required tasks in any applicable
Service Alerts and Service Bulletins.
•
Review and understand all information provided
in Submittals and Design Specifications.
1. General
☐ Inspect chiller for damage (shipping or rigging).
☐ Verify and record unit nitrogen holding charge
pressure.
☐ Inspect water piping for proper installation.
☐ Inspect strainers, flow sensing devices,
isolation valves, pressure gauges, thermometer
wells, flow balancing valves, vent cocks, and
drains.
☐ Inspect cooling tower piping.
☐ Verify proper clearances.
☐ Power wiring meets size requirement.
☐ Verify proper voltage and amperage rating.
☐ Verify proper foundation installation.
☐ Verify unit isolator pads/springs have been
installed.
☐ Verify low voltage circuits are isolated from high
voltage circuits.
☐ Check equipment room for ventilation, refrigerant
monitor, rupture disk piping, and Personal
Protective Equipment (PPE).
Note: All conditions which do not conform to the
established requirements for unit installation MUST
be corrected prior to start-up. Any non-conforming
condition which is not corrected prior to start-up
must be noted in the Non-Compliance Form (PROD-
ADF001*-EN) by the start-up technician; this
information must also be signed by responsible site
personnel before start-up and the completed Non-
Compliance Form will become part of the start-up
record, submitted with a Start-up Check Sheet and a
Chiller Service Report.

2. Pre-Start Operations
☐ Verify nitrogen holding charge.
☐ Calibrate the high pressure cutout control
(HPC).
☐ Meg compressor motor.
☐ Confirm proper oil pump operation.
☐ Evacuate unit.
☐ Check condenser installation.
☐ Check evaporator installation.
Do Not Apply Electrical Power to a
Unit in a Vacuum!
Failure to follow instructions below could
result in motor and compressor damage.
Do not apply electrical power to a motor in a
vacuum.
For units with inside-the-delta solid state
starters, disconnect power to unit during
evacuation or when the unit is in a deep
vacuum. In addition, on units with inside-the-
delta solid state starters, all power to the unit
must be disconnected prior to evacuating the
unit as line power is directly applied to the
motor terminals 4, 5, and 6.
☐ Check electrical and controls.
☐ Inspect motor starter and control panel.
☐ Confirm all wiring connections are tight, free of
abrasion and have no sharp bends in panel and
on compressors.
☐ Inspect contactors and relays.
☐ Verify unit wiring (low and high voltage) is
correctly isolated, phased, and properly
grounded.
☐ Connect external 120 Vac power to power up
the control panel.
☐ Run the oil pump to verify pump can provide 18
to 22 psid (124.1 to 151.7 kPaD) net pressure.
☐ Verify and record control parameters.
☐ Verify all control interlocks are installed and
properly functioning.
☐ Set AFD grounding jumpers (PE-A for MOV and
PEB for Common Mode) for power distribution
grounding:
☐ Both jumpers "Connected" for Solidly
Grounded System (Center Ground Wye).
