Pre-Installation
Mandatory Start-up Checklist
This checklist is not intended to be a substitution for
the contractors 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 (Addendum_PROD-SVX01 latest version)
for appropriate procedures, component specications
and safety instructions.
Except where noted; it is implied that the technician is to
use this checklist for inspection / verication 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. CXAX condensor coil will 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
Wiring Interlock and externals (chilled water pump)
11. Field installed control wiring landed on correct
terminals (external start/stop, emergency stop,
chilled water reset…)
12. Verify all refrigerant and oil valves are open/back
seated
13. Compressor oil levels (1/2 -3/4 high in glass) proper
14. Verify chilled water strainer is clean and free of
debris and evaporator chilled water circuits are lled
15. 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.
16. Close the fused-disconnect switches that supplies
power to the chilled water pump starter
17. 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.
18. With water circulating through the system, adjust
water ow and check water pressure drop through
evaporator
19. Return chilled water pump to auto
20. Verify all the chiller controller Menu Items.
21. All panels/doors secured prior to start-up
22. All coil ns inspected and straightened
23. Rotate fans before starting unit to inspect for
potential audible and visual signs of rubbing.
Start unit
24. Press AUTO key. The unit will start if the chiller
control calls for cooling and the safety interlocks are
closed
25. Check the evaporator and the condenser refrigerant
pressure on the chiller controller.
26. Conrm Superheat and subcooling values are normal
27. Compressor operation normal and within amperage
rating
28. Operating log completed
29. Press stop key
30. Inspect fans again after being under load to ensure
no signs or rubbing exist
31. Verify the chilled water pump runs for at least
1 minute (possibility to congure maxi 10 mn) after
the chiller is commanded to stop (for normal chilled
water systems)
Unit storage
If the chiller is to be stored for more than one month
prior to installation, observe the following precautions:
• Store the chiller in a dry, vibration-free, secure area.
• Units charged with refrigerant should not be stored
where temperatures exceed 68°C.
• 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 qualied service organization
and the appropriate Trane sales ofce.
• If the refrigerant pressure is below 13 bar (R410A)
/ 12.5 bar (R454B) at 20°C or 10 bar (R410A) / 9.5 bar
(R454B) at 10°C, call a qualied service organization or
Trane Sales Ofce.
The Trane Company will not assume responsibility for
equipment damage resulting from accumulation of
condensate on the unit electrical components.
Note: if the unit is stored before servicing near a
construction site it is highly recommended to protect
micro channel coils from any concrete and iron element.
Failure to do so may considerably reduce reliability of
the unit.
