WARNINGS:
Shock Hazard
• Under NO circumstances should anyone enter the water with the mixer connected or in operation.
• Running the unit out of water will create a dangerous situation and damage the seals.
• NEVER lift the unit by the power cord. If you need to remove the mixer, use the installation or mount
apparatus.
• The unit must be connected to a GFCI-protected circuit.
• Comply with local and national wiring standards during any electrical service disconnect.
• Consult a qualied professional for electrical installation.
• Use all Personal Protective Equipment necessary for safe ingress, installation, and egress from the
work site.
• Refer to applicable national and local laws and standards to facilitate the safe installation of a
CertiSafe Tank Mixer. These may include but are not limited to OSHA, CCOHS, and other regulations
related to:
• Working over or near water
• Fall protection systems
• Falling object protection systems
• Electrical standards
• Illumination
• Ventilation
• Installation of CertiSafe™ Tank Mixers requires entry into environments that pose potential hazards,
such as those described in section 1910.146 of OSHA’s Occupational Safety and Health Standards for
Permit-required conned spaces. As such:
• Observe any applicable pre-entry measures required by the entry supervisor.
• Only those authorized via the permit system in place at the installation site should participate
in installation.
• Any authorized entrant should be accompanied by at least one authorized attendant to
monitor conditions inside and outside the permit spaces during installation.
• Prior to installation, be aware of all potential fall, trip, and atmospheric hazards in the permit
space, both before and after an entrance cover is removed.
SAFETY FIRST
CERTISAFE™ TANK MIXER MANUAL 3
Back to Contents
Kasco oers a variety of mounting options to best position a CertiSafe™ mixer in any tank environment,
all featuring durable stainless steel. There are also several optional control panels.
These mounting kits are designed for proper placement AND retrieval of CertiSafe™ mixers.
Once installed, ONLY remove mixers via the retrieval method specic to the mount.
PM-100
Pipe Mount
The PM-100 makes use of other
structures in the tank to position
the mixer. Use the upper mount
parts above the water line to
adjust the unit’s vertical position
and to swivel the lower mount
parts and the attached mixer.
(Pre-cut stainless steel pipe not
included.)
Standard CS-100, CS-200
• Motor contactor
• HOA, Manual or Automatic control through
SCADA input
• Low water automatic shuto
• UL 4X/3R enclosure
• 120V panel uses a 20A single pole
circuit breaker
• 240V panel uses a 30A single pole
circuit breaker
Advanced CS-150, CS-250
All standard features PLUS:
• Ground fault protection
• HOA, Hand and Auto position dry contacts
for SCADA
• Mixer fault dry contact for SCADA
• Mixer running dry contact for SCADA
• Larger 4X/3R enclosure
Advanced models are also available in stainless
steel (CS-150SS & CS-250SS)
RM-100
Floor Mount
The RM-100 positions the
mixer stably on the tank oor
and comes with a retrieval
chain to safely lift the unit for
observation and maintenance.
Protective feet on each of the
legs are designed to prevent
any damage to the tank. (Note:
minimum clearance is 24” for
square hatches, 25” for round
hatches.)
Suspended Mount
Suspended from the tank roof,
the SM-100 uses a 60” stretcher
bar to support the mixer in a
raised position within the tank.
Two chains adjust the unit’s
elevation and facilitate safe
removal for observation and
maintenance.
The ASM-100 accessory kit
includes an additional 60”
stretcher bar.
The SM-50 Suspended Mount
includes a 30” stretcher bar.

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 stratication 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. Eective 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.

Depending on the mount option you choose, two or three tank penetration holes will be required. The
rst is a either a 7/8” or 1-7/64” diameter hole, depending on the cord gauge. This is for the cord grip,
shipped with the CertiSafe™ Tank Mixer. Others are 3/8” in diameter (.281” for SM-50 Suspended Mount),
for eye bolts that hold the cable support and any chains included with the mount.
For reference, all tank penetration measurements are detailed below, followed by instructions for the
cord grip pass-through. Instructions and equipment for additional tank penetration are included with the
CertiSafe™ mounting kits.
To prevent galling, we recommend a moisture-cured, polyurethane compound sealant suitable for contact
with potable water and certied to meet the shrinkage for interior and exterior use. Refer to NSF/ANSI
Standard 61 for indirect additives.
• The maximum tank roof thickness accommodated by the tank penetration parts included is 1/8”.
• Suggested measurements are based on a 24” square access hatch.

1. Drill a 7/8” hole (or 1-7/64” hole for 10 AWG cable) at the distance suggested for your mount.
See page 6 for details.
2. Deburr both sides of the hole. This is for the cord grip.
3. From the tank exterior, pass the cord grip (A) through the clearance hole, with the O-ring outside the
tank roof.
4. From the tank interior, t the cord grip nut (B) on the threads protruding into the tank.
5. Tighten the nut (B) until snug, being careful not to over-tighten.
6. Feed the power cable through the cable support (C).
• The cable support hangs on a connecting link suspended from an eye bolt. The connecting link
and eye bolt are included with CertiSafe™ mounting kits.
7. Continue to feed power cable through the cord grip (A) and out of the tank until all excess cord length
has been taken up, only leaving enough so that there is no strain on the cable.
8. Tighten the top nut on the cord grip to seal the power cable penetration.
9. Terminate the power cable into an exterior junction box (not supplied by Kasco).

Once installed, its placement within the tank and powerful active mixing capabilities make
Kasco’s CertiSafe™ Tank Mixer an ideal anchor point for common third-party NSF-approved
chemical injection nozzles.
• For this purpose, we recommend that you x any nozzles (not supplied by Kasco) to the unit’s
cage, spaced as shown below.
• Use stainless steel hose clamps to secure the nozzle body to the cage, ensuring that the nozzle is
snug against the cage and that the tip is below the propeller.
• Shown here with two nozzles, solutions will be mixed together with the water pulled through
the propeller.
