Pre-Installation
Preparation for Initial Startup
After the system is completely installed with all wires
connected and all piping securely coupled, the chiller/
heater can be prepared for initial startup.
Ensure there is a sufficient cooling load available for
proper testing of the chiller/heater.
Initial Startup
1. Close all drain valves and header purge valves.
2. Fill the chiller/heater with clean water/glycol mixture.
3. Inspect all connections for leaks during the filling
process.
4. De-energize 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 ensure terminals
are secure.
6. Inspect all fuses and overload settings to ensure they
conform to specifications.
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.
7. Inspect all refrigerant pressures for each module to
ensure no refrigerant has been lost.
8. Check that pressure switches and thermostats have
correct “cut-in” and “cut-out” settings.
9. Confirm the oil level is correct in each compressor.
10. Connect phase monitor wiring, if required.
11. Connect remote flow switch if the chiller/heater is so
equipped.
12. Ensure refrigerant valves are open at the compressors.
13. Confirm that pressure and temperature switches are in
the closed position.
14. Apply power to all modules in the chiller/heater.
15. Turn on the condenser and evaporator fluid pumps and
ensure there is proper flow and the pressure drop
across the system is as expected.
16. Monitor and record all temperatures and refrigerant
pressures.
Request Initial Startup
Initial startup is an exacting, complex, procedure.
Successful initial startup is directly attributable to
thorough preparation and completion of all essential tasks
prior to the scheduled initial start-up date.
A completed Request for Initial Startup form is required
prior to scheduling a startup.
Submission of this form indicates all critical work
described on the form has been completed. To prevent
incurring additional startup charges, it is critical that all
items listed on the form are completely functional and
operating, with this form signed and returned to Trane, at
least 10 working days prior to scheduling an initial startup.
(See“Appendix B- Request for Initial Startup,” p. 74’)
As part of a continuous commitment to quality, initial
startup of this chiller/heater by a certified factory
technician may be purchased from Trane.
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.
CAUTION
Compressor Failure!
Failure to follow instructions below could result in
catastrophic compressor failure. Do not operate with
insufficient oil.
