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.

• Under NO circumstances should anyone enter the water with the electrical equipment

plugged in and/or in operation. All Kasco De-Icers are ETL approved to UL and CSA stan­dards for safety in water. However, it is NEVER
equipment in operation.

• Caution should be used when dealing with any electrical and/or moving equipment. Al-

ways keep people and objects clear of the propeller when operating.

• 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 open water, especially cold water, which poses a

hazard in and of itself.

• Always disconnect the electrical power before servicing or removing your De-Icer.

• NEVER lift or drag the De-Icer by the power cord. This could damage the power cord and

make your De-Icer unsafe

• Kasco Marine recommends that precautions be taken around open water de-icing areas to

to operate. If you need to pull the unit, use the mooring ropes.

ensure the safety of the public, i.e., “Thin Ice” and/or “Open Water” signs, appropriate
lighting, fencing, or other safety measures required in your area.

• The De-Icer is supplied with an internal grounding conductor and a grounding-type attach-

ment plug. To reduce the risk of electrical shock, be certain that the De-Icer is plugged into
a GFI protected circuit.

• 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.

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, Warranty Claim, & Return Policy on pages 4 & 5). Please register your De-Icer online at:
www.de-icer.com/solutions_warranty_registration.htm

.

USE AND OPERA TION

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

Your Kasco Marine De-Icer is ready for immediate use (after installation). The motor is of an oil­filled design with ball bearings submerged in oil and equipment 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.)

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 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.

WARRANTY, WARRANTY CLAIM, & RETURN POLICY

2 Year Limited Warranty: Kasco

workmanship (except for the ropes, power cord, ropes, and propeller) under normal use and service. The
Kasco Marine, Inc. obligation under this warranty is limited to replacing or repairing free of charge any
defective part within two (2) years from the date of shipment. Customer shall pay shipping charges for

returning the unit to Kasco or an Authorized Repair Center.

THIS WARRANTY IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESSED OR IMPLIED,
AND ANY OTHER OBLIGATION OR LIABILITY WHATEVER ON THE PART OF KASCO
MARINE, INC. AND IN NO EVENT SHALL KASCO MARINE, INC. BE LIABLE FOR ANY
SPECIAL OR CONSEQUENTIAL DAMAGES.

Warranty is void if:

•

The De-Icer is not maintained properly according to the Maintenance Recommendations supplied in this
Owners Manual.

•

The De-Icer is returned for repair without the power cord or if the unit or power cord are altered in any
way from original shipment. Cuts in the power cord are not covered under warranty.

•

The De-Icer is damaged by unauthorized tampering.

•

The Sacrificial Zinc Anode around the propeller shaft shows significant deterioration. (The Anode must be
inspected periodically and replaced if necessary.)

Note: There are certain conditions under which no circulator can prevent ice damage such as ice that moves
due to wind or current, extremely cold weather where ice forms all the way to the bottom and in some cases
where the bottom water temperature is the same as ice (very shallow water). Effective operation can be some­what reduced when flow is restricted by too little bottom clearance.

Warranty Claim Procedure:

Check the ten-digit serial number printed either on the black cover of the motor or on the blue nameplate and
determine the year of manufacture according to the serial number scheme below:

Sample Serial #

6001

D 2 1725

•

The first two digits represent the reverse of the last two digits of the year of manufacture.

Example: 60 = 2006 model year.

•

The third and fourth digits represent the week of the year. (Ex. “01” for 1st week in Jan.)

•

The fifth digit represent the model. (Ex. “D” for 2400D)

•

The sixth digit represents the horsepower of the unit in fourths: 2 = 2/4 = 1/2HP, 3 = 3/4HP, 4 = 1HP.

•

The remaining four digits are sequential.

The best method for establishing warranty period is registering your De-Icer online at the below address and/or
the original receipt. If the customer has registered the De-Icer online at:
www.de-icer.com/solutions_warranty_registration.htm
Kasco Marine will have a record of the purchase and will be able to determine whether or not the unit still car­ies warranty coverage.

Once the warranty coverage has been established, the unit may be sent to any Kasco Authorized Repair Center
for evaluation and repair. Please call Kasco Marine at 715-262-4488 prior to shipping to receive a Return
Authorization Number and/or Repair Form, then ship to:

Kasco Marine, Inc.

Or call Kasco Marine at 715-262-4488 to locate your nearest Authorized Repair Center. You can also email
Kasco at [e-mail]

.

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 float with the mo­tor assembly, unless specifically asked to by a Kasco representative.

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 ac­cording to the instructions in the previous section. Again, it is best to call ahead for a Return Authorization
Number and/or Repair Form so we know the repair is coming.

Kasco Marine offers free 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 per-

formed.

• We will repair the unit only if repair costs are under a stated dollar amount. Example: “Please repair if to-

tal 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.

Billing:

All non-warranty repairs will be returned to the customer and billed C.O.D. unless otherwise directed. Kasco
Marine also accepts Visa and MasterCard credit card payments. Kasco Marine will call for credit card infor­mation upon completion of the repair at the customer’s request.

All other warranty and repair inquiries should be directed to Kasco Marine, Inc. at 715-262-4488 or

MAINTENANCE RECOMMENDATIONS

** Under No Circumstances should anyone enter the water while a De-Icer 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 De-Icer 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. 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 715-262-4488 for further instructions or email Kasco at ser­[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 fishing line. Even though Kasco De-Icers are 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.

• SUMMER STORAGE: You Kasco De-Icer can be used during non-freezing times of the year to improve

water circulation and prevent stagnant water areas and poor water quality. If you do decide to store the unit
during non-freezing times it is not necessary to store Kasco motors upside down. All internal seals are fully
lubricated while stored in an upright position.

• CLEANING: De-Icers should be removed from the water at least once per season 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 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 break 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 where the De­Icer runs most or all of the year, it is a good idea to replace seals more regularly than you would need to in
situations where the unit is removed from the water for several months.

• ZINC ANODE: A Sacrificial Zinc Anode is supplied on the shaft of all De-Icers for protection of the

equipment from corrosion and electrolysis. It is extremely important that the zinc anode 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; monthly in saltwater).

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.

DE-ICER INSTALLATION INSTRUCTIONS

De-Icing is often referred to as more of an art form than an exact science because each situation is different
and unique. Kasco offers three basic ways for De-Icer installation, Vertical or Rope Suspension, Universal
Dock Mount Installation, or Angled or Horizontal Float Installation. Different De-Icing objectives may re­quire different mounting/installation options.

STEP ONE

How and where to locate your 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. Both of these concerns or objectives are very different and may require very
different installations.

STEP TWO

Once you have determined your De-Icing objective, the next thing to do is determine the best location(s) for
installation. Remember, a De-Icer draws warmer, denser water from the bottom (39
mately 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. Up to a point, the deeper the water,
the warmer the water; however, if your De-Icer is installed too deep, the rising warmer water will not effec­tively spread at the surface, thereby reducing the De-Icing effect.
