Start-up Tasks to be Performed By Trane
Safety Alert!
In addition to the follow ing tasks, you M UST:
• Follow all instructions in the chiller's Installation, Operation, and M aintenance manual, including w arnings, 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.
General
• Inspect chiller for dam age (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, therm om eter w ells, flow balancing valves, vent
cocks, and drains.
– Inspect cooling tow er piping.
• Verify proper clearances.
• Pow er w iring m eets size requirem ent.
– Verify proper voltage and am perage rating.
• Verify proper foundation installation.
• Verify unit isolator pads/springs have been installed.
• Verify low voltage circuits are isolated from high voltage circuits.
• Check equipm ent room for ventilation, refrigerant m onitor, rupture disk piping, and PPE.
N ot e: All conditions w hich do not conform to the established requirem ents for unit installation m ust be corrected prior to start-
up. Any non-conform ing condition w hich is not corrected prior to start-up m ust be noted in the Non-Com pliance Form
(PROD-ADF001-EN) by the start-up technician; this inform ation m ust also be signed by responsible site personnel before
start-up and the com pleted Non-Com pliance Form w ill becom e part of the start-up record, subm itted w ith a Start-up
Check Sheet and a Chiller Service Report.
Pre-Start Operations
• Verify nitrogen holding charge.
• Calibrate the high pressure cutout control (HPC).
• M eg com pressor m otor.
• Check condenser installation.
• Check evaporator installation.
Do Not Apply Electrical Power to a Unit in a Vacuum!
Failure to disconnect power to units w ith inside-the-delta solid state starters during evacuation or w hen 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 w ith 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 m otor starter and control panel.
– Confirm all w iring connections are tight, free of abrasion and have no sharp bends in panel and on com pressors.
– Inspect contactors and relays.
– Verify unit w iring (low and high voltage) is correctly isolated, phased, and properly grounded.
– Connect external 120 Vac pow er to pow er up the control panel.
