Start-Up Procedure
Considerations for Initial Start-Up
•
For units with independent fan control [standard on units with the BALTIDRIVE
•
For units with VFDs, see Page 54.
•
For units with vibration cutout switches, see Page 42.
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 fans and the pump motor are disconnected, locked out, and tagged out.
•
The unit must be level in both the length and width directions for proper operation.
Cleaning
•
Drain the basin with the strainer in place.
•
Remove all dirt and debris from the fan guard(s) and combined inlet shields.
•
Inspect and clean all spray nozzles.
•
Clean all the mechanical components, such as the fan and motor.
•
Remove accumulated dirt and debris from the water guards.
•
Flush the 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 fans 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.
•
Check and adjust the belt tension. Units equipped with the EC Fan System use direct drive motors and do not require belt
tension.
