Kasco Marine 50Hz Aerator & Circulators - Manual (Page 9)

installation of the aerator as detailed in the aerator
owner’s manual.
Record the following data while the unit is operating
in the water under load:
Voltage: Amperage:
L1-L2 ____________ L1_______________
L1-L3 ____________ L2_______________
L2-L3 ____________ L3_______________
Current unbalance should not exceed 5% at full load
Installation Instructions
STEP ONE
Use the ropes to position the Unit in the desired loca-
tion in the pond/lake (secure the cord near power
source to prevent it from being dragged into the wa-
ter). Anchor the ropes or secure them to the shoreline
so the ropes are free of slack, but not tight. To prevent
twisting of the unit due to torque, you should place the
anchor at least 3m from the fl oat for every 1 meter of
depth (Ex. A 3m deep pond would require an anchor
9m horizontally from the fl oat.) For ease of removal,
you may choose to keep at least one anchor within
reach from shore, just below the water’s surface.
Correct Anchoring
Incorrect Anchoring
STEP TWO (ALTERNATE INSTALLATION)
In ponds where the water level fl uctuates signifi cantly,
you may need to suspend a small weight (30cm of
2.54cm galvanize pipe works well) at the mid-point of
the rope to take up any slack as the water level drops.
The weight should be light enough so the Unit can rise
as the water level rises. This can also help hide ropes
by sinking them further below the surface.
Control panels must be installed by a qualifi ed electri-
cian.
If unit is connected to a circuit protected by a fuse, use
a time-delay fuse with this pump.
You must verify motor rotation before installing
the unit in the water.
3phase Kasco units will run in a clockwise rotation
when looking down at the propeller/impeller. On J
series units the upper pump housing must be removed
to see the propeller/impeller. Stand clear of the
propeller/impeller while verifying rotation. Follow
the steps below.
Electrician:
Verify all screw terminal connections are tightened to 1.
specifi ed torque setting prior to energizing the panel.
Verify the electrical service (voltage and Phase)
2.
matches the control panel and aerator nameplates
ratings. Refer to your control panel instructions and
schematics for installation details.
Verify all switches, circuit breakers, and motor starters
3.
are in the OFF position
Connect electrical service to your control panel as
4.
shown in the electrical schematic that came with the
panel.
Connect the unit power cord to the panel as shown in
5.
the electrical schematic with your panel
Set the motor starter overload to the FLA rating on the
6.
aerator nameplate.
Pump rotation: Remove the upper pump housing (if 7.
you have a J series aerator ) by removing the three
screws attaching it to the lower pump housing. The
pump rotation is clockwise when looking down at the
propeller/impeller. Apply power to the control panel.
Turn on the 15amp control circuit breaker, and motor
starter.
Momentarily turn the Hand-Off-Auto switch to Hand.

This will run the aerator . Do not run the aerator for
more than a few seconds on shore. If the rotation is
not correct. Disconnect and lock out power from the
control panel. Swap any two of the
aerator power cord
wires in the panel. This will cause the motor to reverse
direction. Reapply power to the panel and verify the
rotation is clockwise.
Once rotation is verifi ed, with the power disconnected

and locked out again, reinstall the upper pump housing.
Run the
aerator one more time momentarily on
shore to ensure the housing was reinstalled correctly.
Disconnect and lock out power again and continue with
