Start-Up; Pre-Startup Checklist - Trane VUV Installation, Operation And Maintenance Manual

Start-Up

Pre-Startup Checklist

Complete this checklist after installing the unit to verify all
recommended installation procedures are complete before
unit start-up. 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 a CAT III or IV voltmeter rated
per NFPA 70E that all capacitors have discharged.
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.

• 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
