Included with this instruction packet are separate User Manuals on each
major operating component of the tower, and it is recommended that you
read them thoroughly. Where discrepancies may exist, the separate User
Manuals will take precedence.
The following is recommended as a minimum routine of scheduled
maintenance:
Always shut off electrical power to the tower fan motor prior to
performing any inspections that may involve physical contact with
the mechanical or electrical equipment in or on the tower. Lock out
and tag out any electrical switches to prevent others from turning the
power back on. Service personnel must wear proper personal
protective clothing and equipment.
Weekly: Inspect for bacterial growth and general operation conditions.
Bacterial growth should be reported to your water treatment expert for
immediate attention.
Monthly (Weekly at start up): Observe, touch, and listen to the tower.
Become accustomed to its normal appearance, sound, and level of
vibration. Abnormal aspects relating to the rotating equipment should be
considered reason to shut down the tower until the problem can be located
and corrected. Observe operation of the motor, sheaves, belt, and fan.
Become familiar with the normal operating temperature of the motor, as
well as the sight and sound of all components as a whole.
Inspect louvers, drift eliminators and basin trash screens and remove any
debris or scale which may have accumulated. Replace any damaged or
worn out components. Use of high-pressure water may damage the
eliminator and louver material.
Observe operation of the float valve. Depress the operating lever to make
sure that the valve is operating freely. Inspect the suction screen for
plugging. Remove any debris that may have accumulated.
Check for any buildup of silt on the floor of the cold water basin. Mentally
make note of the amount, if any, so future inspections will enable you to
determine the rate at which it is forming.
