CVHH Start-up Task List Revised: 10 Oct 2014
CVHH Start-up Task List
Start-up Tasks to be Performed By Trane
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 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.
Pre-Start Operations
• Verify nitrogen holding charge.
• Calibrate the high pressure cutout control (HPC).
• Meg compressor motor.
• Check condenser installation.
• Check evaporator installation.
• 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.
WARNING
Safety Alert!
In addition to the following tasks, you MUST:
• Follow all instructions in the chiller’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.
Failure to do so could result in death or serious injury.
NOTICE:
Do Not Apply Electrical Power to a Unit in a Vacuum!
Failure to disconnect power to units with inside-the-delta solid state starters during evacuation or when the unit is in
a deep vacuum could cause compressor motor damage. Applying electrical power to a motor in a vacuum could
cause damage to the motor. 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.
