AMCOT ST SERIES FIBERGLASS COOLING TOWER

GENERAL OVERVIEW
GENERAL OPERATING PRECAUTIONS
PERFORMANCE
Since the volume of water has a direct impact on cooling tower performance, be sure that the water
flow rate is constantly maintained during operation. Fluctuations in water flow will directly impact
cooling tower performance. Low flow rates can cause excessive scale and algae growth. Scale and algae
accumulation can be minimized by incorporating a water treatment program (chemical or non-chemical
types). It is best to contact the installing contractor or local representative for further assistance in
these matters.
WATER LEVEL
Proper water level in the cold water basin should be maintained at all times. The recommended water
level is 2-3 inches below the overflow. If the water level in the basin becomes too low this can allow air
to enter your piping and cause pump cavitation. Closely monitor your float valve assembly or electronic
level controller and ensure a proper water level is maintained.
NOISE/VIBRATION
Pay close attention to general operating conditions of your tower such as noise, vibrations, water
temperature, and motor voltage. Sudden changes in any of these items can be an indicator that a
problem has begun to develop and ultimately failure if you do not address the problem in a timely
manner. Sudden increases in vibration can mean a fan assembly is cracked or out of balance or
structural brackets may be compromised. Sudden shifts in voltages or amp draws can mean that
reducer belts need to be adjusted or motor bearings could be failing or something is wrong with the
power supply connected to the motor.
REPLACEMENT PARTS
Amcot stocks most parts for ST Series cooling towers in our Ontario, California facility. Amcot
replacement parts are available through major HVAC wholesalers and distributors along with other
authorized equipment distributors.
Only the use of original Amcot components is recommended. Using third party components that are not
original factory parts will void your tower’s warranty and could have significant impact on the towers
rated capacity or performance.
If you are unsure of who your local supplier is, please call Amcot at 1-800-444-8693 and we will be more
than happy to assist you with finding an authorized dealer.
