FAN MOTOR
During operation it is required to clean the outside surface of the motor at least every 6 months (or more often
depending on site conditions) to ensure proper motor cooling. Do not wash down the motor unless it is IP 66 rated.
On a quarterly or six monthly basis check:
•
Electric connections
•
Motor protection devices
•
Check amp draw
•
Motor bearings for noise/overheating
•
Motor holding bolts
•
External surface of motor for corrosion
SPRAY WATER PUMP
The BAC pump contains a mechanical seal between pump housing and pump motor. This seal needs to be
checked quarterly for proper operation and replaced if necessary.
ELECTRIC WATER LEVEL CONTROL PACKAGE (OPTIONAL)
The electric water level control package (optional) maintains a constant water level in the cold water sump
independent of cooling load changes and water supply pressure variations. Ensure every six months that all
components (valve, float switches) are operational and clean.
During commissioning the tower should be filled manually till overflow level (push float ball under) to prevent air
suction of the pump during first start-up.
CAUTION
When disassembling the float switch for cleaning, make sure to reassemble it in
exactly
the same
position, otherwise it will not function correctly.
