Pre-Installation
Preparation for Initial Startup
After the system is completely installed with all wires
connected and all piping securely coupled, the chiller
can be prepared for initial startup.
Ensure there is a sufficient cooling load available for
proper testing of the chiller system.

Initial Startup
1. Close all drain valves and header purge valves.
2. Fill the chiller with clean water/glycol 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 ensure
terminals are secure.
6. Inspect all fuses and overload settings to ensure
they conform to specifications.
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.
N N o o t t e 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.

10. Connect phase monitor wiring, if required.
11. Connect remote flow switch if the chiller 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. (If a tank
and pump module is included, there are switches
inside the module control cabinet to start the
pumps. Ensure that the pump rotation is correct.)
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.
