Fan-Related Checks
•
If the unit is not externally isolated, ensure that the fan isolator tie-down bolts have been
removed. See the
“Fan Isolation” section on page 39
for more information.
•
Rotate all fan wheels manually to confirm they turn freely in the proper direction.
•
Check fan shaft bearings, fan wheel, and drive sheave set screws for proper torque settings (see
Table 16 on page 77
and
Table 23 on page 86
).
–
Fan sheaves should be tight and aligned.
–
Bearing set screws should be torqued. See
Table 16 on page 77
for torque values.
•
Check fan drive belt tension. See the
“Tension the Fan Belt” section on page 75
.
•
Inspect fan motor and bearings for proper lubrication, if necessary. See the
“Fan Bearing
Lubrication” section on page 86
.
•
Check the motor lubrication, if necessary.
–
Remove and clean grease plugs.
–
Check for moisture in the grease. If moisture is present, remove the motor and send it to an
authorized repair shop for bearing inspection/replacement. If no moisture is present, refer
to the motor manufacturer’s lubrication recommendations for proper lubrication.
Coil-Related Checks
NOTICE
Proper Water Treatment!
The use of untreated or improperly treated water in coils may result in scaling, erosion,
corrosion, algae or slime. It is recommended that the services of a qualified water treatment
specialist be engaged to determine what water treatment, if any, is required. Trane assumes no
responsibility for equipment failures which result from untreated or improperly treated water, or
saline or brackish water.
•
Ensure coil and condensate drain piping connections are complete.
•
Check the piping and valves for leaks.
–
Open or close the valves to check operation.
–
The drain lines should be open.
•
If unit has a refrigerant coil, ensure that it has been charged and leak-tested according to the
instructions provided with the condenser equipment. Adjust the superheat setting.
•
Remove all foreign material from the drain pan and check the pan opening and condensate line
for obstructions.
•
For steam coils, slowly turn the steam on full for at least 10 minutes before opening the fresh
air intake on units with fresh air dampers.
