Start-Up

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.

Motor-Related Checks

Obtain an IOM from the motor manufacturer for the specific motor installed. The motor

manufacturer’s recommendations take precedence for all matters related to the start-up and

routine maintenance of the motor.

• Check the motor lubrication for moisture and rust.

– Remove and clean grease plugs to inspect.

– If moisture is present, consult an authorized repair shop for bearing inspection/replacement.

This may require removal and transport of motor.

– If no moisture is present, refer to the motor manufacturer’s lubrication recommendations for

proper lubrication.

– The motor manufacturer may recommend lubricating the motor as part of their routine

startup instructions.

• Check motor winding. An acceptable winding resistance reading is from 6 meg-ohms to infinity.

If reading is less than 5 mega-ohms, the winding should be dried out in an oven or by a blower.

• Inspect the entire motor for rust and corrosion.

• Bump-start the unit and confirm the fan wheel rotates properly, as indicated by the rotation

arrow located on the fan housing.

Note: Note: For motor warranty needs, contact you local Trane sales office.
