Maintenance Recommendations

Under No Circumstances should anyone enter
the water while a unit is operating. Turn Off and Dis-
connect electrical power prior to any Maintenance or
Servicing
RCD (Residual Current Device) or GFCI are a safety
feature that can also alert you to electrical leaks in the
equipment. It is extremely important to test the RCD
upon installation, each reinstallation, and monthly
thereafter to ensure proper operation. If you have
repeat, consistent trips on your ground fault, the equip-
ment should be disconnected and removed from the
water. The power cord should be inspected for dam-
age and you should call a Kasco Marine distributor or
representative for further instructions.
If the supply cord becomes damaged, it must be
replaced by an authorized service center, or similarly
qualifi ed 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 observed, the equipment should be dis-
connected 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 fi sh-
ing 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 fl ow of water. These
materials can be very damaging to the equipment un-
der continued operation and must be removed as soon
as possible. ALWAYS DISCONNECT POWER TO
THE UNIT BEFORE ATTEMPTING TO REMOVE
CLOGS.
WINTER STORAGE: In regions where there is
signifi cant 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 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
O
and cool, but above 0 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 be-
come 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 de-
pending on conditions. In most cases a power washer
will be suffi cient 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 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 Sacrifi cial Zinc Anode is supplied
on the shaft of all Kasco 50Hz Aerators & Circula-
tors 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 associ-
ated 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.
Pollution of the liquid could occur due to leak-
age of lubricants. If leakage is detected, shutdown and
have the unit removed for repair.
