Maintenance Recommendations

** Under No Circumstances should anyone enter the

water while a aerator is operating. **

** Please keep the original box for maintenance ship-

ping. **

The following maintenance procedures can be uti-

lized to ensure many years of quality performance

from your Kasco aerator 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 (GFI). For aerator models,

the C-25 control (120V) or C-85 (240/208V) included

with the unit have built-in ground fault interrup-

tion that is sufficient. 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

[email protected].

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 ma-

terial that may have clogged the system or wrapped

around the shaft of the motor, especially plastic bags

and fishing line. Even though Kasco Aerators and

aerators 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 equip-

ment under continued operation and must be removed

as soon as possible. ALWAYS UNPLUG THE UNIT

BEFORE ATTEMPTING TO REMOVE CLOGS.

WINTER STORAGE: In regions where there is sig-

nificant freezing in the wintertime, the 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 ex-

posed to the colder air temperatures longer and can ac-

tually 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 32

O

F. 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.

CLEANING: Aerators 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 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 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 cli-

mates where the aerator 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 VFX Model aerators for protection

of the equipment from corrosion and electrolysis. The

zinc anode should 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 pre-

caution, 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. Any alterations or changes

made to Kasco units by an unauthorized source will
