Important Safety Instructions

Please read and follow this 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.

  • Under NO circumstances should anyone enter the water with the electrical equipment plugged in and/ or in operation. 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 internal 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 qualified electrician. · Ground Fault Circuit Interrupters (GFCI) should be tested upon each installation and every month thereafter to ensure proper operation.

General Owner’s Instructions

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.

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.

Please see the proper Assembly and Installation Instructions enclosed in this manual. Each is specific 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 float. If you have a light kit, make sure that the unit cord is tied to one side of the float and the light cord to the other for balance. Note: It is extremely important to test the GFI breaker in the control panel upon each installation/reinstallation of the unit to ensure proper functioning.

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).

Kasco aerators are designed and engineered for continuous duty, such as on fish farms or other aquaculture applications, or ondemand use, as needed in a recreational water feature. During flotation operation, the water is pulled from 360 degrees around the unit and from below the unit. The water is pulled upward and thrust through the flotation 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 sufficient voltage is supplied to the aerator motor. Unit should be protected by a GFCI. Control panels must be installed by a qualified electrician. (See Installation instructions).

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.

  6. Turn upright. Secure power cord to rope hole
  7. If ready to install in the pond, go to Installation instructions. Light Kits can also be installed at this time, go to Light kit instructions.

VFX Installation Instructions

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 float for each foot of depth (Ex. A 6 foot deep pond would require an anchor 18 feet horizontally from the float.)

Alternate Installation Instructions:
In ponds where the water level fluctuates significantly, 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.

Control Panel Installation

  1. 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. 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/flexing 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 to be waterproof. It is also advised to mount the panel out of direct sunlight if possible by mounting the panel in a North direction. Also, mount the panel above the potential flood plain to prevent water entry during a possible flood event.
  2. Set Timer in the control panel to desired ON and OFF times per the Instructions for each specific timer.
  3. Follow all local and national electrical codes for this installation and Consult a qualified electrician or service person if needed.
    a. (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!
    b. (For 240V Installations ­ 3400H, 4400H) All electrical connections to this panel must be made with proper strain relief cord grip fittings or with conduit connections as required by local and national electric codes.

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.
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 interruption that is sufficient. 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 [email protected].

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 fishing 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 flow 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.

WINTER STORAGE: In regions where there is significant 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. 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 32OF. 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.

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 sufficient 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 Sacrificial 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).
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 Kasco Marine, Inc. at 715-262-4488 for your nearest Authorized Repair Center.

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 Fault Interrupter (GFI) breaker that trips can in- dicate an electrical service problem, water contamination in the unit and/or cord, bad breaker, control box problems, motor problems, etc. Try to find 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.
“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 first 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 byan 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 find 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 buildup of algae, calcium or organic matter on the unit, remove the debris and, if caught early enough, the unit should be fine. Contact a Kasco representative before restarting the unit.
“My Aerator flow seems to fluctuate 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 flow or pattern will fluctuate 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.
