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 system.
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.
N No otte e:: 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.
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
“ PolyTherm Chiller/Heater ,” p. B–1 )
As part of a continuous commitment to quality, initial
startup of this chiller/heater by a certified factory
technician may be purchased from Trane.
