Start-Up Procedure - BAC FXV-0806-12D Series Operation & Maintenance Manual

Start-Up Procedure

Considerations for Initial Start-Up
• For units with independent fan control, see Page 41.
• For units with VFDs, see Page 15.
• For units with vibration cutout switches, see Page 40.
General
• If the unit is mounted on vibration isolators or isolation rails (by others), refer to the
vibration isolation manufacturer's guidelines before loading/unloading weight from the
unit.
• Verify fan and unit pump motors are disconnected and locked out.
Cleaning
• Drain the cold water basin with the strainer in place.
• Remove all dirt and debris from the fan guard(s).
• Inspect and clean all spray nozzles.
• Clean all mechanical components, such as the fan and motor.
• Flush the cold water basin interior to remove any accumulated dirt and debris.
• Remove, clean, and replace the strainer.
Inspection
• Conduct external inspection of the equipment. Check for leaks, corrosion, and any
structural damage.
• Conduct internal inspection of the equipment. Check for anything unusual such as
structural or mechanical component damage.
• Inspect piping and connections.
• Thoroughly inspect the fan(s) for any mechanical or physical damage.
• At seasonal start-up or after prolonged shutdown, check the motor insulation with an
insulation tester prior to the motor start-up.
• For belt drive units, prior to seasonal start-up, check and adjust the belt tension. At
initial start-up, the belt tension may not require adjustment as the drive will be
properly tensioned at the factory prior to shipment.
• For gear drive units, verify adequate oil level and check all fittings to ensure there
are no visible leaks. Refer to "Gear Drive System" on Page 17 for initial start-up
instructions.
• For ENDURADRIVE Fan System Units, Refer to Page 14 for initial start-up
®
instructions.
