AMCOT ST SERIES FIBERGLASS COOLING TOWER

GENERAL MAINTENANCE
Pipe Connections
Overflow Connection
Your tower is fitted with an overflow connection (FPT) and overflow assembly. The overflow is
designed to ensure that water level does not exceed a predetermined level which could cause structural
damage to the basin or cause water to overflow out of the basin and flood the immediate area. The
tower should never be operated without the overflow in place. Failure to operate the tower without a
proper overflow connection can cause damage to the cooling tower or surrounding
equipment/property.
Drain Connection
Each tower is also supplied with a drain connection (FPT). This connection is typically used when
removing water from the system for either cleaning, maintenance, or replacement of the circulating
water. The drain connection should be piped to a facility drain which delivers this water to your local
municipality. This drain connection is often used as a bleed connection for siphoning small volumes of
water out of the system to prevent the buildup of dissolved solids within your system. Bleed or blow
down is critical to the overall quality of your circulating water. For more information on this, please see
the water treatment section of our manual on page 47.
Automatic Filler Connection
On models ST-200 to ST-1500 towers, there is an additional quick fill connection (MPT) adjacent
to your standard make-up connection where the mechanical float valve is attached. The quick fill
connection is optional and allows for an additional make-up connection that can be utilized when either
filling the system with water initially or following maintenance to speed up the process. This connection
should only be used in those cases and is not intended for use during normal operation.
WARNING: YOUR PIPING MUST BE PROPERLY SUPPORTED IN ACCORDANCE WITH GOVERNING CODES
REQUIRED BY YOUR LOCAL, COUNTY, OR STATE REGULATIONS. IN ADDITION, THE COOLING TOWER IS
NOT DESIGNED NOR CONSIDERED A PIPE SUPPORT. THEREFORE ALL PIPE CONNECTIONS MUST BE
PROPERLY SUPPORTED WITHIN 12 INCHES OF THE POINT OF CONNECTION. FAILURE TO PROVIDE
PROPER PIPE SUPPORT COULD DAMAGE YOUR COOLING TOWER AND VOID YOUR WARRANTY.
