your purchase. Your decision to purchase Kasco’s
VFX model Aerator will not disappoint you. The VFX
model Aerator will be a great addition to your body
of water. It will help improve the water quality by
adding much needed oxygen and circulation. It will
also enhance the aesthetics of the pond or lake with a
beautiful pattern. The lighting package (if purchased)
will illuminate your aerator for beauty at night. We
thank you for choosing Kasco for your aerator needs

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 qualied
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 specic
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 sufcient
voltage is supplied to the aerator motor. Unit should
be protected by a GFCI. Control panels must be
installed by a qualied electrician. (See Installation
instructions).
Kasco aerators are lightweight, energy efcient, 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.

7. See “Mesh Screen Attachment” section before
connecting the bottom screen to the oat. Position the
Bottom Screen (Part #B9) over the oat so the motor
housing (can) passes through the large hole in the center of the screen. Remove the center three 3/8” Lock
Nuts from the 9” Bolts and place the Bottom Screen
Clips (Part #B13) over the bolts as shown. The power
cord can be slid under the bottom screen between the
oat and screen where two oat sections come together before the 3/8” Lock Nuts are replaced. Replace the
three inside Lock Nuts and tighten all 3/8” Lock Nuts
using the 9/16” wrench and socket.
