Startup; Pre-Startup Checklist - Trane UniTrane Installation, Operation And Maintenance Manual

Startup

Pre-Startup Checklist

Complete this checklist after installing the unit to verify all
recommended installation procedures are complete
before unit startup. This does not replace the detailed
instructions in the appropriate sections of this manual.
Disconnect electrical power before performing this
checklist. Always read the entire section carefully to
become familiar with the procedures.
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by Trane
or others, refer to the appropriate manufacturer's
literature for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN
Note: Some circumstances may require the unit to run
before building construction is complete. These
operating conditions may be beyond the design
parameters of the unit and may adversely affect the
unit.
General Checks
• Ensure the unit has been installed level.
• Ensure supply-air and return-air ducts have been
connected.
• Ensure damper operator motors and connecting
linkage have been installed.
• Verify damper operation and linkage alignment.
• Check that air filters are in place and positioned
properly.
• Remove any debris from the unit interior.
• Remove all foreign material from the drain pan and
check drain pan opening and condensate line for
obstructions.
• Inspect electrical connections to the unit and unit
controllers.
– Connections should be clean and secure.
– Compare the actual wiring with the unit diagrams.
– Reference the appropriate controller manual for
more details about starting units with factory-
mounted controls.
UNT-SVX07J-EN
• Check piping and valves for leaks. Open or close the
valves to check for proper operation. Drain lines should
be open.
• Leave this manual with the unit.
Fan-Related Checks
• Rotate fan wheel manually to confirm it turns freely in
the proper direction.
• Verify the fan and motor are aligned.
Coil-Related Checks
NOTICE:
Proper Water Treatment!
The use of untreated or improperly treated water in
coils could 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.
• 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.
Electrical Checks
• Check all electrical connections for tightness.
• Verify motor voltage and amps on all phases with the
unit nameplate ratings to ensure unit operates
correctly.
Ductwork Checks
• If using return ductwork to the unit, secure it with three
inches of flexible duct connector.
• Extend discharge duct upward without change in size
or direction for at least one and one half fan diameters.
• Use a 3-inch flexible duct connection on discharge.
• Ensure trunk ductwork is complete and secure to
prevent leaks.
• Verify that all ductwork conforms to NFPA 90A or 90B
and all applicable local codes
