INSPECTION PRIOR TO START-UP
Start-up and Commissioning
ROTATION OF FANS
Fans must rotate without obstruction in the direction indicated by arrows on the equipment.
MOTOR VOLTAGE AND CURRENT
Check the voltage and the current of all three legs of the fan motors. The current should not exceed the nameplate
rating. After prolonged shutdown the motor insulation should be checked with a Megger insulation tester prior to
restarting.
The voltage must not fluctuate more than +/-10% and the imbalance between phases must not be greater
than +/-2%.
UNUSUAL NOISE AND VIBRATIONS
Unusual noise and/or vibration are the result of malfunctioning of mechanical components or operational problems
(e.g. unwanted ice formation). If this occurs, a thorough inspection of the entire unit followed by immediate
corrective action is needed. If required, consult your local BAC Balticare representative for assistance.
PURGE REQUIREMENTS
The installer of BAC closed circuit cooling towers must ensure a proper air purging of the system prior to operation.
Entrained air can restrict the capacity of the cooler, resulting in higher process temperatures.
For water quality guidelines and for calculation of Practical Scaling Index, refer to the Operating and Maintenance
Instructions, section Water Care.
