Inspection checklist
When the unit is delivered, verify that it is the correct
unit and that it is properly equipped. Compare the
information which appears on the unit nameplate with
the ordering and submittal information.
Inspect all exterior components for visible damage.
Report any apparent damage or material shortage to
the carrier and make a “unit damage” notation on the
carrier’s delivery receipt. Specify the extent and type of
damage found and notify the appropriate Trane Sales
Office. Do not proceed with installation of a damaged
unit without sales office approval.
Mandatory Start-up Checklist
This checklist is not intended to be a substitution for the
contractor’s installation instruction. This checklist is
intended to be a guide for the Trane technician just prior
to unit ‘start-up’. Many of the recommended checks and
actions could expose the technician to electrical and
mechanical hazards. Refer to the appropriate sections in
the unit manual for appropriate procedures, component
specifications and safety instructions.
Except where noted; it is implied that the technician is to
use this checklist for inspection / verification of prior task
completed by the general contractor at installation.
1. Unit clearances adequate for service and to avoid air
recirculation, etc
2. Unit exterior inspected. Condenser coils shall not be
obstructed at any time by snow or ice during winter
conditions
3. Unit properly grounded
4. Crankcase heaters working for 24 hours prior to
arrival of Trane technician performing start up
5. Correct voltage supplied to unit and electric heaters
(imbalance not to exceed 2%)
6. Unit power phasing (A-B-C sequence) proper for
compressor rotation
7. Copper power wiring meets sizing requirement in
job submittal
8. All automation and remote controls installed/ wired
9. All wiring connections tight
10. Prove chilled water side Interlock and
Interconnecting
11. Wiring Interlock and externals (chilled water pump)
12. Field installed control wiring landed on correct
terminals (external start/stop, emergency stop,
chilled water reset…)
13. Verify all refrigerant and oil valves are open/back
seated
14. Compressor oil levels (1/2 -3/4 high in glass) proper
15. Verify chilled water strainer is clean and free of
debris and chilled/hot water circuits are filled
16. A pressure switch device to detect lack of water is
not included in the pump package. Installation of
this type of device is highly recommended to avoid
sealing damage due to operation of pump without
enough water
17. Close the fused-disconnect switches that supplies
power to the chilled water pump starter
18. Start the chilled water pump to begin circulation
of the water. Inspect piping for leaks and repair as
necessary. Check the physical presence of the water
pressure switch
19. With water circulating through the system, adjust
water flow and check water pressure drop through
Chilled/Hot Water Exchanger.
20. Return water pumps to auto
21. Verify all the unit controller Menu Items
22. All panels/doors secured prior to start-up
23. All coil fins inspected and straightened
24. Rotate fans before starting unit to inspect for
potential audible and visual signs of rubbing. Start
unit
25. Press AUTO key. The unit will start if the unit control
calls for cooling or heating and the safety interlocks
are closed
26. Check the suction and discharge refrigerant pressure
on the unit controller
27. Confirm Superheat and sub-cooling values are
normal
28. Compressor operation normal and within amperage
rating
29. Operating log completed
30. Press stop key
31. Inspect fans again after being under load to ensure
no signs or rubbing exist
32. Verify the water pumps run for at least 1 minute
(possibility to configure maxi 10 mn) after the unit
is commanded to stop (for normal chilled water
systems)
Unit storage
If the unit is to be stored for more than one month prior
to installation, observe the following precautions:
•
Store the unit in a secured area, to avoid intentional
damages.
•
Close the suction, discharge and liquid-line isolation
valves.
•
Store the unit in a dry, vibration-free, secure area.
•
At least every three months, attach a gauge and
manually check the pressure in the refrigerant
circuit.
•
If the refrigerant pressure is below 13 bar at 20°C (or
10 bar at 10°C), call a qualified service organization
and the appropriate Trane sales office.
Note: If the unit is stored before servicing near a
construction site it is highly recommended to protect
coils from any concrete and iron element. Failure to do
so may considerably reduce reliability of the unit.
