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).

established requirements for unit installation

MUST be corrected prior to start-up. Any nonconforming 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

Relieve nitrogen holding charge.

Evacuate and charge the system.

Apply power to the starter panel.

Verify current to the oil sump heater.

Set Purge mode to “On.”

Bump-start the compressor and verify compressor motor rotation.

Start chiller.

Verify no unusual noises or vibrations and observe operating conditions.

If necessary, adjust oil pressure regulator between 18 to 22 psid (124.1 to 151.7 kPaD) net.

Measure and verify refrigerant pump pressure.

When chiller is stable, take system log three times at 15-minute intervals.

Set Purge mode to “Adaptive.”

Reset the “Starter Energy Consumption” resettable.
