Water Treatment
Control of slime, algae, and bacteria growth is extremely important. Cooling towers and
reservoir pump tanks are superb environments for microorganism growth. Warm water,
organic debris, and air encourage bacterial growth. Treat your system with chemicals
(microbiocides) to control microorganism growth.

Caution! Uncontrolled microorganism growth causes system problems such as fouling
and corrosion, and can spread bacterially-transmitted diseases.
You must reduce slime growth and bacterial contamination to eliminate disease-causing

Routine Maintenance
• The fan motor has double-sealed bearings and needs no lubrication
• Inspect basket strainers (where used) and clean as needed.
• Check constant bleed back to the tank for flow during operation.
• Check the bleed-off line to verify that water flows to the drain during operation.
• Inspect the tower basin for dirt and debris, and clean as needed.
• Check the tower nozzle(s) for proper operation at full water flow.
• Check the water treatment equipment for proper operation. Refer to the information
