The Kasco CertiSafe™ Tank Mixer is part of a submerged active mixing system. It is intended for potable 

water tanks (20,000 gallons and larger) to eliminate thermal stratification and ice formation, as well as 

maintain residual disinfectant uniformity.
CertiSafe™ mixers are shipped prepared for use. The motor is equipped with thermal overload protection; 
however, the mixing unit must be continuously submerged to ensure safe operation. It is important that 
the installation provides appropriate voltage to the motor.
Operating the mixer continuously provides maximum water circulation in your tank. Optional system 
controls are available from Kasco for mixer units (see page 4).

CertiSafe™ systems have a maximum operating depth of 50 feet. Effective mixing can be achieved in 

deeper tanks with mounting at or above this depth.

This manual will cover the tank penetration process necessary to pass the power cable through 
the tank roof during installation. Individual mount manuals contain information on additional tank 
penetration and unit installation.
