Safety Instructions

CAUTION

•Under NO circumstances should anyone enter the water with the electrical equipment connected and/or in operation. 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 unit 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 unit installation, such as a canoe, and follow all boating safety rules and regulations, including wearing a PFD. (Personal Flotation Device)

•The unit is supplied with an internal grounding conductor. To reduce the risk of electrical shock, be certain that the unit is plugged/ connected to an approved GFCI protected circuit.

•Means for disconnection must be incorporated in the fixed wiring in accordance with local and national wiring rules.

•Consult a qualified electrician for electrical installation.

Note: Under certain conditions, no de-icer can prevent damage from ice movement caused by wind or current, or from extremely cold weather.

General Owner’s Instructions

INSPECT THE SHIPMENT

Immediately inspect your Kasco De-Icer 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 Instructions enclosed in this manual. Each is specific for your model and size of De-Icer and De-Icer accessory.

WARRANTY

Kasco De-Icers are the result of over 40 years of design and engineering. Kasco products are built to withstand the toughest conditions. Kasco Marine backs each De-Icer with a 2 Year Warranty. This warranty covers any and all manufacturers defects within 2 years from the date of purchase (See Warranty Policy). Please register your De-Icer online at: www.de-icer.com/solutions_warranty_registration.htm.

USE AND OPERATION

Kasco De-Icers are designed and engineered for continuous duty in the harshest environments, such as in marinas or other commercial applications, or ondemand use, as may be needed.

Your Kasco Marine De-Icer is ready for immediate use (after installation). The motor is of an oil-filled design with ball bearings submerged in oil and equiped with a thermal overload protection with an automatic reset. No further lubrication is necessary. It is extremely important that the installer make sure sufficient and proper voltage is available to the unit’s motor. The zinc anode located below the propeller must be in good condition in order to prevent corrosion damage to the unit. The zinc anode must be inspected periodically and replaced if it shows significant deterioration. Make sure to keep the motor housing clean from hard water deposits and/or algae. (See Maintenance Recommendations on page 6.)

Note: If the De-Icer has been stored or exposed to cold for an extended period without running, it may take a minute for the prop to get to full speed once power is supplied.

The De-Icer is also completely assembled, you do not need bolts, screws, nails, or brackets, unless an optional mounting device was purchased. All you have to do is suspend it in as little as two (2) feet of water from piers, docks, or boats and plug it into a properly grounded and GFI protected 15 amp outlet.

Kasco De-Icers are lightweight, energy efficient, and

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

Please Note: Under certain conditions, no de-icer can prevent damage from ice movement caused by wind or current, or from extremely cold weather causing ice to form all the way to the bottom and in some cases where bottom water temperature is the same as the ice. Effective de-icing can also be retarded when used in extremely shallow conditions.

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.

De-Icer Installation Instructions

Kasco offers three basic ways for De-Icer installation: Vertical Rope Suspension, Universal Dock Mounting kit, or Angled / Horizontal Float Installation. Different De-Icing objectives may require different mounting/

installation options.

STEP ONE

Locating a De-Icer depends on your De-Icing objectives. If ice expansion pressure is your concern, you may find it easier to have an open-water buffer between your dock or structure and the expanding ice pack.

If ice lifting or a combination of lifting/expansion is your concern, you may wish to keep your dock, structure, or boat area completely ice free. These objectives are different and may require different installations.

STEP TWO

Determine the best location(s) to install. A De-Icer draws warmer, denser water from the bottom (4OC is approximately water’s densest point) and circulates it upward to the surface. Around docks and boats water is usually fairly shallow, so look for somewhat deep water to install your De-Icer. However, if your DeIcer is installed too deep, the rising warmer water will not effectively spread at the surface, thereby reducing the De-Icing effect.

Note: A good guide is 4-6 feet deep for vertical installation, and slightly shallower for angled operation, but at least 1 foot off the bottom to prevent clogging from debris. In colder climates, warmer water is a more important factor than surface circulation, so you may wish to install your De-Icer deeper than the above guide lines. De-Icers generally will work in shallower water, but are less effective and due to the constraints of your installation, you may have to settle for a shallower installation. It is

recommended that you experiment with more than one possible location for the best installation results.

STEP THREE

When you have determined both your De-Icing objectives and best installation points, it is time to analyze what external constraints your De-Icing location (structures, i.e., dock, boat, etc.) may have that could affect the flow of warmer water at the surface. Any obstruction at the surface of the water may slow or stop the flow of warmer water. A natural current, such as in a river, will tend to force your DeIcing efforts downstream.

Once you have determined your external constraints,

you can choose your installation point(s). Some useful tricks you may wish to consider are:

•De-Ice from the upstream side and let the current help, rather than hinder.

•Boats are designed to allow water to flow from the bow to the stern with the least resistance. It is generally easier to De-Ice a boat by installing the De-Icer at or near the bow, angled to push the DeIcing flow of water toward the stern.

•It is generally easier to De-Ice a shallow area by bringing the warmer water from a deeper area into the shallow area. Angle your De-Icer from the deeper water toward the shallow water.

•When using more than one unit, it is better to angle all units in one direction, creating a current rather than installing De-Icers in opposing directions.

•In tidal waters, split the difference in water depth so the De-Icer is in shallow water at low tide and deep water at high tide. If you are De-Icing a boat, it is easier to tie your De-Icer to the boat and allow the boat and De-Icer to rise and fall with the tide together.

STEP FOUR

When installing your Kasco De-Icer for suspended operation with the provided ropes, make sure the ropes or suspension lines are spread at least 8 to 10 feet apart. The high starting torque of your Kasco De-Icer may cause suspension lines that are too close together to twist up and possibly damage the electrical power cord. Tie each rope with a secure knot from the dock piling, cleat, boat etc. so the De-Icer hangs vertically.
