Start-Up

Preparation for Initial Start-Up

After the system is completely installed with all wires
connected and all piping securely coupled, the chiller can
be prepared for initial start-up.
Confirm there is a sufficient cooling load available for
proper testing of the chiller system.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.

Initial Start-Up Checklist

1. Close all drain valves and header purge valves.
2. Fill the chiller with clean fluid mixture.
3. Inspect all connections for leaks during the filling
process.
4. De-energize chiller using industry-standard lockout/
tagout procedures. Verify main power is turned off at
the power distribution panel. Validate de-energization
using voltage meter.
5. Inspect all electrical connections to confirm terminals
are secure.

6. Inspect all fuses and overload settings to confirm they
meet specifications.
7. Inspect all refrigerant pressures for each module to
confirm no refrigerant is lost.
8. Confirm the oil level is correct in each compressor.
Note: If Trane pumps are provided, check that each
pump's overload setting matches the nameplate
amperage of the pumps as described previously.
"Bump" pump motors on to verify correct rotation.
NOTICE
Compressor Failure!
Failure to follow instructions below could result in
catastrophic compressor failure.
Do not operate with insufficient oil.
9. Connect phase monitor wiring, if required.
10. Confirm refrigerant valves are open at the
compressors.
11. Confirm that pressure and temperature switches are in
the closed position.
12. Apply power to all modules in the chiller system. (If a
tank and pump module is included, there are switches
inside the module control cabinet to start the pumps.
Confirm that the pump rotation is correct.)
13. Turn on the evaporator fluid pumps and confirm there is
proper flow and the pressure drop across the system is
as expected.
