OPERATION MANUAL
IMPORTANT: PLEASE READ THIS MANUAL AND SAVE FOR FUTURE REFERENCE.
Safety First
•Under NO circumstances should anyone enter the water with the mixer connected
or in operation.
•Running the unit out of water will damage the seals and create a dangerous
situation.
•NEVER lift the unit by the power cord. If you need to remove the mixer, use the
installation cables or installation apparatus.
•The unit must be connected to an GFCI protected circuit.
•Electrical service disconnect in accordance with local and national wiring
standards.
•Consult a qualified professional for electrical installation.
System Overview
The Kasco CertiSafeTM 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 maintaining residual
disinfectant uniformity.
CertiSafeTM 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 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.
CertiSafeTM systems have a maximum operating depth of 50ft. Effective mixing can be achieved in deeper tanks with
mounting at or above this depth.

Maintenance Recommendation
IMPORTANT: Disconnect electrical power prior to any maintenance or servicing!
GFCI
GFCI (Ground Fault Circuit Interrupter) is a safety feature that can alert you to problems with the mixer. It is
important to test the GFCI upon installation, each reinstallation, and regularly thereafter to ensure consistent
operation. If you experience repeat interruptions, the equipment should be disconnected and removed. The
power cord and unit (mixer) should be inspected for damage. If no damage is apparent, please contact your
Kasco distributor or representative for further instruction.
Observation
The operating mixer should be monitored for any reduction or variation in performance. If a deficiency in
performance is noted, the equipment should be removed from service and inspected for any damage or failure.
Cleaning
The stainless-steel motor housing needs to be kept clean to allow heat to effectively dissipate.
