Maintenance Recommendations
Under No Circumstances should anyone enter the water
while a unit is operating. Turn Off and Disconnect electri-
cal power prior to any Maintenance or Servicing
Ground fault interrupters are a safety feature that can also
alert you to electrical leaks in the equipment. It is extreme-
ly important to test the GFI upon installation, each reinstal-
lation, 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 a Kasco Marine distributor or representa-
tive for further instructions.
If the supply cord becomes damaged, it must be replaced by
an authorized service center, or similarly qualified persons
in order to avoid a hazard.
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 ob-
served, 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, espe-
cially plastic bags and fishing line. Even though Kasco
Aerators & Circulators 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 AT-
TEMPTING TO REMOVE CLOGS.
WINTER STORAGE: In regions where there is significant
freezing in the wintertime, 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 tempera-
tures 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 0 O C.
CLEANING: Equipment 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 mo-
tor 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 op-
eration of the motor, saving you the cost of more expensive
repairs. In warmer climates where the equipment 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 Kasco Aerators & Circulators for protection of
the equipment from corrosion and electrolysis. The zinc
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 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. Please contact your Kasco Marine, Inc.
distributor or representative for your nearest Authorized
Repair Center.
