Important Safety Instructions

Please read and follow these extremely important
safety and handling instructions for your Kasco equip­ment. Following these instructions will help ensure
your safety and the quality performance of your equip­ment.

nal grounding conductor and/or a grounding-type
attachment plug. To reduce the risk of electrical
shock, be certain the aerator is properly connected
to the Kasco supplied control panel. (refer to the
C-25, C-85 & C-95 Control instructions)

• 3 phase aerators (2.3VFX, 5.3VFX) require a
startup test after wiring to ensure proper rotation of
the propeller. If the propeller is rotating in the op­posite direction, the unit will not perform properly
and internal damage to the unit may occur. (See 3
phase startup procedure)

• Control panels must be installed a minimum of
5ft(3m in Canada) from the inside wall of the
pond, unless separated from the body of water by
a fence wall, or other permanent barrier that will
make the unit inaccessible to persons in the water.

• Control panels must be installed by a qualied

electrician.

• Ground Fault Circuit Interrupters (GFCI) should
be tested upon each installation and every month
thereafter to ensure proper operation.

General Owner’s Instructions

• Under NO circumstances should anyone enter the
water with the electrical equipment plugged in
and/or in operation. All Kasco equipment is ETL
approved to UL and CSA standards for safety in
water. However, it is NEVER recommended to
enter the water with the equipment in operation.

• Caution should be used when dealing with any
electrical equipment with moving parts.

• NEVER run the unit out of water. It will damage
the seals and create a dangerous situation for the
operator.

• Extreme caution should be used around water,
especially cold water, such as in Spring, Fall, and
Winter, which poses a hazard in and of itself.

• NEVER lift or drag the aerator by the power or
light cord. If you need to pull the unit to the side
of the pond, use the anchoring ropes.

• Do not use waders in deep ponds/lakes or ponds/
lakes with drop-offs, drastic slopes, or soft bottom
material.

• Do not use boats that tip easily for aerator installa­tion, such as a canoe, and follow all boating safety
rules and regulations, including wearing a PFD.
(Personal Flotation Device)

• Single phase aerators are supplied with an inter-

INSPECT THE SHIPMENT
Immediately inspect your Kasco Aerator shipment for
any visible damages. Also cross reference the parts
supplied with the Parts Included sheet to check for
shortages. Shortages should be reported immediately
to your Kasco Marine distributor or representative and
damages reported to your carrier and Kasco Marine.

CAUTION
WARNING: Under NO circumstances should anyone
enter the water with the unit in operation. Always
operate the unit in the water and keep people and ob­jects clear of the propeller. Do not lift or pull the unit
by the electrical cord. Always use extreme caution
around electrical equipment and water situations.

ASSEMBLY & INSTALLATION
Please see the proper Assembly and Installation In-

structions enclosed in this manual. Each is specic

for your model and size of aerator. Note: Use a nylon
tie to help keep the power cords for the unit and lights
free of the propeller by tying each cord to either side

of the oat. If you have a light kit, make sure that the
unit cord is tied to one side of the oat and the light

cord to the other for balance. Note: It is extremely

2

important to test the GFI breaker in the control panel
upon each installation/reinstallation of the unit to en­sure proper functioning.

WARRANTY
Kasco aerators are the result of over 35 years of design
and engineering. Kasco products are built to with­stand the toughest conditions. Kasco Marine backs
each VFX model aerator with either a 2 Year or 3 Year
Warranty depending on the model. This warranty cov­ers any and all manufacturers defects within the war­ranty period from the date of purchase (See Warranty
Section). Please register your aerator online at:
www.kascomarine.com (under the technical tab)

USE AND OPERATION
Kasco aerators are designed and engineered for con­tinuous duty, such as on sh farms or other aquacul­ture applications, or on-demand use, as needed in a
recreational water feature.

During otation operation, the water is pulled from

O

360

around the unit and from below the unit. The

water is pulled upward and thrust through the otation

collar into the air.

Your Kasco Marine aerator is ready for immediate use
(after installation). Make sure to keep the motor hous­ing clean from hard water deposits and/or algae. (See
Maintenance Recommendations.)

It is extremely important that proper and sufcient

voltage is supplied to the aerator motor. Unit should
be protected by a GFCI. Control panels must be

installed by a qualied electrician. (See Installation

instructions).

Kasco aerators are lightweight, energy efcient, and

easy to install and operate. We strive to produce prod­ucts that exceed customer expectations. We hope you
enjoy your Kasco aerator.

UNIT STORAGE
When storing units during the offseason, it is impor­tant to store them upside down if they are going to be
sitting for long periods of time. Units that sit upright
on a shelf for many months, or even years have a
greater likelihood of seals drying out. Storing upside
down will ensure oil is lubricating the seals and pre­vent drying.

NOTE: Pattern sizes listed are approximate. Varia­tions in voltage caused by regional electrical differenc­es or voltage drop due to long power cords may result

in reduced pattern sizes.

Mesh Screen Attachment

1. Take at mesh pattern and wrap into cone shape

by overlapping both vertical edges by approximately
1 inch and aligning top and bottom edges of mesh.
Secure mesh vertical seam at the top, bottom and

middle using (3) cable ties.

Note: Extra hardware may be included

8. On power cord lengths of 100 feet or longer with
the watertight Quick Disconnect, the power cord is
shipped separately. It should now be attached to the
stub cord by lining up the male and female halves of
the disconnect and hand tightening the blue collar. On
these cords, the Additional Strain Relief should be

attached to one of the lower oat brackets as pictured.

If you receive a 3 chain strain relief (6 or 8 gauge

cord), attach one chain to each of the three lower oat

brackets. If there is not Strain Relief, use the Nylon
Cable Tie provided to secure the cord to a rope to
prevent damage by the propeller. Double check the
Quick Disconnect to make sure the threaded collar has
not come loose in shipping before placing in the water.

Overlap vertical edges

Attach 3 cable ties

2. Insert existing stainless steel screen centered inside
mesh cone with approximately 2 inches of mesh
overlap to the top ring of the screen. Attach mesh
to the top ring of the screen in (3) equally spaced
locations using cable ties.

Attach 3 cable ties

to top ring equally spaced

VFX Installation Instructions

Before installing 3 phase units (2.3, 5.3) into the pond,
please refer to 3 phase startup procedure.

Use the ropes to position the aerator in the desired
location in the pond/lake. Anchor the ropes or secure
them to the shoreline so the ropes are free of slack, but
not tight. To prevent twisting of the unit due to torque,
you should place the anchor at least 3 feet from the

oat for each foot of depth (Ex. A 6 foot deep pond

would require an anchor 18 feet horizontally from the

oat.)

2 inch overlap

3. Flip mesh and screen assembly over and use
remaining cable ties to secure mesh to small bottom
diameter of the stainless steel ring.

Attach 2 cable ties

to bottom ring equally spaced

ALTERNATE INSTALLATION

In ponds where the water level uctuates signicantly,

you may need to suspend a small weight (12” of 1”
galvanize pipe works well) at the mid-point of the
rope to take up any slack as the water level drops. The
weight should be light enough so the aerator can rise
as the water level rises. This can also help hide ropes
by sinking them further below the surface.

4. Clip off excess cable tie material once mesh is
secured into place. Go back to assembly instructions
to continue with connecting the bottom screen to the

oat.

Control Panel Installation

STEP ONE
Inspect the panel for any damage and any components that
may have loosened during shipping.

Control panel must be installed a minimum of 5ft (3m in
Canada) from the inside wall of the pond, unless separated
from the body of water by a fence wall, or other permanent
barrier that will make the unit inaccessible to persons in the
water.

This control panel requires a 240V or 208V - 4 wire service
(L1, L2, N, & G) and must be fed with a power circuit
protected by a circuit breaker or a fused disconnect switch
to provide circuit protection and a disconnection means.
C-85 panel requires at least a 30amp protected circuit
feeding the panel.
C-95 panel requires at least a 40amp protected circuit
feeding the panel.

Connect your power feed as detailed in the wiring diagram
provided with this panel.

Install the control panel to a post structure, side of a
building, or other reliable means. This structure must

support the panel and prevent movement/exing of the

panel. Use #10 x 1” or longer screws in the mounting
points of the control panel to secure to the post structure.
NOTE: The control panel must be hung upright in order to
be waterproof. It is also advised to mount the panel out of
direct sunlight if possible. Mounting the panel in a North
direction will prevent heat buildup inside the panel. Also,

mount the panel above the potential ood plain to prevent
water entry during a possible ood event.

STEP TWO
Set Timer in the control panel to desired ON and OFF times

per the Instructions for each specic timer.

STEP THREE

Follow all local and national electrical codes for this

installation and Consult a qualied electrician or service

person if needed.

(For 120V Installations)
Plug the aerator cord into the C-25 outlet labeled “UNIT”.
If lights are included, plug the Transformer cord into the
C-25 outlet labeled “LIGHT”. Now you are ready to plug
the C-25 into the 120V power supply on the post and EN­JOY YOUR NEW KASCO AERATOR!

3 Phase: (2.3, 5.3)
Refer to your 3 phase control panel instructions

Single Phase: (3400H, 4400H, 8400, 5.1)
STEP THREE (For 240V Installation)

All electrical connections to this panel must be made

with proper strain relief cord grip ttings or with conduit

connections as required by local and national electric codes.

The bottom of the enclosure is reserved for eld installation

of these connections.

L1 connects to Terminal #1
L2 connects to Terminal #2
N connects to Terminal N
G connects to Terminal GROUND - located on
chassis plate

Be sure to provide adequate sized power conductors
to prevent excessive voltage drop. Consult with your
electrician to properly size power feed conductors. Use
copper conductors only.

Aerator power cord connection:

Your aerator (pump) will be provided with a exible power

cord for connection to this control panel. If the power cord
has a plug, you will need to cut it off. The power cord
conductors (black, white, green) will need to be stripped
back 1/2”. The outer black jacket should be stripped
back at least 3inches. Follow the connection diagram for
terminating these three wires to the terminal blocks in the
control panel.

Black connects to Terminal #4
White connects to Terminal #5
Green connects to Terminal G

Light Kit connection:

If you purchased a Kasco light kit(s) for your aerator,
follow the light kit installation instructions for mounting

the light kit(s) to the aerator oat.

This control panel requires a hardwire connection for
the light kit(s). To connect the light kit(s) you will need
to cut off the power cord plug that is molded to the light
kit power cord. Strip back the black outer jacket of the
light kit power cord at least 3inches to reveal the three
internal wires of the power cord. (black, white, and green
conductors). These three wires will need to be stripped
back 1/2”. Follow the connection diagram for terminating
these three wires to the terminal blocks in the control panel.

Maintenance Recommendations

** Under No Circumstances should anyone enter the
water while a aerator is operating. **
** Please keep the original box for maintenance ship­ping. **

The following maintenance procedures can be uti­lized to ensure many years of quality performance
from your Kasco aerator and reduce the need for more
costly repair work.

However, when the water is thrust into the air, it is ex­posed to the colder air temperatures longer and can ac­tually make ice thicker on the pond/lake. Storage over
winter is best in a location that is out of the sun and
cool, but above 32

O

F. When storing units during the
offseason, it is important to store them upside down
if they are going to be sitting for long periods of time.
Units that sit upright on a shelf for many months, or
even years have a greater likelihood of seals drying
out. Storing upside down will ensure oil is lubricating
the seals and prevent drying.

PROPER INSTALLATION: Proper installation of
Kasco equipment will include a power source with
ground fault interruption (GFI). For aerator models,
the C-25 control (120V) or C-85 (240/208V) included
with the unit have built-in ground fault interrup-

tion that is sufcient. Ground fault interrupters are

a safety feature that can also alert you to electrical
leaks in the equipment. It is extremely important to
test the GFI upon installation, each reinstallation, and
monthly thereafter to ensure proper operation. If you
have repeat, consistent trips on your ground fault, the
equipment should be disconnected and removed from
the water. The power cord should be inspected for
damage and you should call Kasco Marine at 715­262-4488 for further instructions or email Kasco at
[e-mail].

OBSERVATION: Operating equipment should be
observed on a regular basis (daily, if possible) for any
reduction or variation in performance. If a change
in performance is observed, the equipment should be
disconnected from power and inspected for any ma­terial that may have clogged the system or wrapped
around the shaft of the motor, especially plastic bags

and shing line. Even though Kasco Aerators and

aerators are among the most clog-resistant on the
market, it is impossible to protect against all items that

can clog equipment and still maintain a ow of water.

These materials can be very damaging to the equip­ment under continued operation and must be removed
as soon as possible. ALWAYS UNPLUG THE UNIT
BEFORE ATTEMPTING TO REMOVE CLOGS.

CLEANING: Aerators should be removed from the
water at least once per year (at the end of the season
in cold climates) to clean the exterior of the system,
especially the stainless steel motor housing (can). The
motor housing is the surface that dissipates heat into
the water and any algae, calcium, etc. build-up will be­come an insulator that blocks heat transfer. In warmer
regions it is recommended that the motor is removed
and cleaned at least two to three times per year de­pending on conditions. In most cases a power washer

will be sufcient if the unit and algae are still wet.

SEAL AND OIL REPLACEMENT: This is a sealed
motor assembly and seals will wear out over time
(similar to brake pads on a car). Replacement of the
seals and a change of oil after three years may add
longevity to the operation of the motor, saving you
the cost of more expensive repairs. In warmer cli­mates where the aerator runs most or all of the year,
it is a good idea to replace seals more regularly than
you would need to in colder climates where the unit is
removed from the water for several months.

ZINC ANODE: A Sacricial Zinc Anode is supplied

on the shaft of all VFX Model aerators for protection
of the equipment from corrosion and electrolysis. The
zinc anode should be updated (replaced) if reduced to
half the original size or if white in color. Corrosion
from electrolysis is more commonly associated with
saltwater or brackish water, but as a matter of pre­caution, it is important to periodically check the zinc
anode in all installations (at least every two to three
months).

WINTER STORAGE: In regions where there is sig-

nicant freezing in the wintertime, the aerators should

be removed from the water to protect them from the
expansion pressure of the ice. In many areas, aerators
will keep some amount of ice open through the winter.

18

Seal replacement and all other repair services should
be performed by Kasco Marine or a Kasco trained
Authorized Repair Center. Any alterations or changes
made to Kasco units by an unauthorized source will

void the warranty. This includes tampering with the
unit, power cord, and/or control box. Please contact

Note: Only complete motor assemblies will be ac­cepted for warranty repair. The power cord and all
other components must be returned with the motor
as originally assembled. Any missing parts will be
replaced at the customer’s expense and, if determined
to have caused the failure, could void the entire war­ranty. Some parts are essential for structural support
during shipping and others, such as the power cord,
are essential to properly diagnose potential causes of
failure. It is not necessary to return the control box or

oat with the motor assembly.

Warranty is void if:

• The aerator is not maintained properly according
to the Maintenance Recommendations supplied in
this Owners Manual.

• The aerator is returned for repair without the
power cord or if the unit, control box, or power
cord are altered in any way from original ship­ment. Cuts in the power cord are not covered
under warranty.

• The aerator is damaged by unauthorized tamper­ing.

• The Sacricial Zinc Anode around the propeller
shaft shows signicant deterioration. (The Anode

must be inspected periodically and replaced if
necessary.)

Please include the Repair Form received from Kasco
Marine or your local distributor with the shipment. If
no Repair Form is available, include your name and
physical address for return delivery of the repaired
unit and a daytime phone number and/or e-mail ad­dress for correspondence regarding the warranty
claim.

Any expedited shipping method for the return of the
unit is at the customer’s expense. Kasco Marine will
return units repaired under warranty at our expense via
ground freight within the continental United States.

Other Repairs:
Most failed equipment can be repaired at substantially
lower costs than replacement with new. Please ship

19

zation Number and/or Repair Form so we know the
repair is coming.

Kasco Marine does estimates on repairs at the request
of the customer. The request for estimate should be
included in the letter that accompanies the returned
unit and must include a daytime phone number and/or
e-mail address. Estimate options are as follows:

We will contact the customer with a total after the unit
has been evaluated, but before the work is performed.
We will repair the unit only if repair costs are under a
stated dollar amount. Example: “Please repair if total
is under $150.00 before shipping charges.”

All estimates that are rejected for repair will be de­stroyed unless otherwise directed by the customer. If
the customer would like the unit returned, the unit will
be restored as closely as possible to the condition in
which it was received and shipped at the customer’s
expense for shipping and handling charges.

Fault Interrupter (GFI) breaker that trips can in­dicate an electrical service problem, water contamina­tion in the unit and/or cord, bad breaker, control

box problems, motor problems, etc. Try to nd out the

answers to these questions before you contact
Kasco to narrow down the problem.

• How long does it take to trip the breaker?

• Does it always take the same amount of time to

trip?

• How many times has it tripped?

• Has there been any electrical problems in the area

recently?

“My Aerator seems to run slowly.”

This can also be a symptom of several possible
problems. There could be an electrical problem where
the unit is not getting the proper voltage. This could
also indicate a problem with the motor of the unit,
which needs to be looked at by an Authorized Repair
Center. Check that the unit is receiving the proper
voltage, and, if so, contact Kasco for further steps.

Billing:

All non-warranty repairs will be returned to the cus­tomer prepaid with Visa or Mastercard or shipped
C.O.D. with C.O.D. charges unless otherwise directed.
Kasco Marine will contact for credit card informa­tion upon completion of the estimate at the customer’s
request.

Troubleshooting Tips

Below are some helpful troubleshooting tips. If a
problem occurs, please double check the assembly and
installation instructions as well as the instructions for
the proper control panel. More troubleshooting tips
can be found at www.kascomarine.com (under the
technical tab)

“My Aerator trips the ground fault interrupter in the
C-25, C-85, or C-95.”

This is the most common symptom of several
possible problems. To correctly diagnose the problem,
you will need to collect more information. A Ground

“My Aerator hums, but will not start. When I spin
the prop with a stick, it starts up.” (single phase units
only)

This indicated a problem with the Starting
Capacitor. Each Kasco aerator is equipped with a

Starting Capacitor to get the unit going when it is rst

plugged in. If it is operating, but not spinning and can
be started by spinning the prop with a stick, the Start­ing capacitor needs to be replaced by an Authorized
Repair Center.

“My Aerator turns itself off and back on without the
timer and without tripping the GFI breaker.” (single
phase units only)

Each Kasco aerator has a Thermal Overload
built in that will turn the unit off when it overheats.
Once the unit has cooled down, it will start back up. If
you are noticing these symptoms, the unit should be
unplugged immediately because the Thermal Overload
will continue to turn on and off until it burns out and
damages the motor. The unit should be unplugged and

taken out of the water to nd the cause of the problem.

The problem could be one of many, such as, low water
levels, build-up on the unit to prevent heat dissipation,
something inhibiting the free rotation of the shaft, etc.
If something is caught in the unit or there is a build-up
of algae, calcium or organic matter on the unit, remove
the debris and, if caught early enough, the unit should

20

be ne. Contact a Kasco representative before restart­ing the unit.

“My Aerator ow seems to uctuate and/or be less

than usual.”

This can occur because of a few different rea­sons. Most of the time, this symptom is caused from
unit being clogged with debris. A mat of weeds, many
leaves, plastic bags, etc. can clog up the unit and cause
it to be starved of water. If the unit does not have the
proper amount of water, the ow or pattern will uc­tuate up and down and look sporadic. If you are see­ing these symptoms, unplug the unit and clean away
the debris that is clogging up the screen. Another
possibility if these symptoms are noticed, is a chipped
or damaged prop that is causing the unit to wobble and
not pump properly. When the unit is unplugged, check
the prop for damages and replace if damage is found.

“The GFI breaker trips randomly and sporadically.
Sometimes it is a few hours of operation, other times it
can be days or weeks.”

This is referred to as a Nuisance Trip. This
usually occurs where the unit is installed a great
distance from the initial electric service on the prop­erty where the ground stake is placed. It is caused by
either induced current in the ground wire or a base
voltage difference due to soil pH levels. To resolve
the problem, contact an electrician and install a local
grounding stake. This may eliminate the induced cur­rent and any base voltage differences. This problem
can also be caused by a bad breaker or receptacle or
having unbalanced incoming voltage lines.
