Schedule of Tower Maintenance:
Included with this instruction packet are separate Service Manuals on each
major operating component of the tower, and it is recommended that you
read them thoroughly. Where discrepancies may exist, the separate Service
Manuals will take precedence.
Do not use the top horizontal surface of the tower as a working
platform. The tower is designed so that all maintenance can be
performed from the exterior and interior of the tower. Do not use
the upper basin covers as a walking surface or working platform.
Remove basin covers and use portable ladders whenever performing
service on the hot water basin. Use of ladder should be in accord
with manufacturer’s recommendations
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 Visually inspect the cooling tower to assess general operating
conditions and for signs of microbial growth and appearance of debris,
scale and corrosion. Refer to ASHRAE Standard 188 and Guideline 12
for specific frequency recommendations. Consult a knowledgeable water
treatment professional to maintain cooling tower hygiene.
Monthly (Weekly at Start-up) Observe, touch, and listen to the tower. Be-
come 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, driveshaft, Geareducer 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.
Check Geareducer oil level. Shut down the unit and allow 5 minutes for the
oil level to stabilize. Add oil if required. Check system for leaks if the amount
of oil required appears unusual. (If oil is added at the external fill port, allow
adequate time for the level to stabilize before reading final level.)
