DE-ICER MANUAL
8
Under NO circumstances should anyone enter the water while a de-icer is operating. Turn off and discon
-
nect electrical power prior to any maintenance or servicing. RCD (Residual Current Device) or GFCI are safety
features that can also alert you to electrical leaks in the equipment. It is extremely important to test the
GFCI upon installation, following each re-installation, and monthly thereafter to ensure proper operation. If
you experience repeated or consistent ground fault trips, disconnect the equipment and remove it from the
water. The power cord should be inspected for damage, and you should call a Kasco distributor or represen-
tative for further instructions. If the supply cord becomes damaged, contact Kasco for replacement instruc-
tions or reach out to an authorized service center in order to avoid electrical hazards.
Observation
Operating equipment should be observed on a regular basis (daily, if possible) for any reduction or varia-
tion in performance. If you observe a change in performance, 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 among the most clog-resis
-
tant 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 DISCONNECT POWER TO THE UNIT BEFORE ATTEMPTING TO REMOVE CLOGS.
Cleaning
Remove equipment from the water at least once per year 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. buildup will become an insulator that blocks heat transfer. In warmer regions,
we recommend removing and cleaning the motor at least two to three times per year depending on condi-
tions. In most cases, a power washer will be sufficient if the unit and algae are still wet. Avoid power-wash
-
ing the mechanical seal area directly.
Seal And Oil Replacement
This is a sealed motor assembly, and seals will wear out over time (similar to brake pads on a car). Replace-
ment 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.
Sacrificial Anode
A sacrificial anode is supplied on the shaft of all Kasco De-icers for protection of the equipment from corro
-
sion and electrolysis. The anode should be 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 anode in all installations, at least every two to three
months.
Seal replacement and all other repair services should be performed by Kasco or a Kasco-trained Authorized
Repair Center. Please contact your Kasco distributor or representative for your nearest Authorized Repair
Center.
Unit Storage
When storing units during the off-season, it is important to store them with the cage 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 help
prevent drying.
