Initial & Seasonal Start-Up
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, locked out, and
tagged out.
Cleaning
• Drain the cold water basin with the strainer in place.
• Remove all dirt and debris from the fan guard(s).
• Flush the water distribution system. Inspect and clean all spray nozzles.
• Clean all of the mechanical components, such as the fan and motor.
• Flush the cold water basin to remove any accumulated dirt and debris.
• Remove, clean, and replace the basin 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 PCT belt driven units, prior to seasonal start-up, check and
adjust the belt tension. At the initial start-up, the belt tension may
not require adjustment as the drive will be properly tensioned at the
factory prior to shipment.
WARNING: Do not perform any
service on or near the fans,
motors, and drives, or inside
the unit without first ensuring
that the fans and pumps are
disconnected, locked out, and
tagged out.
