Each aerator should have its own starter complete with heaters or adjustable overload
protection sized for the rated current and set properly (usually to the motor’s service
factor amp draw). A fused disconnect should also be provided on the main circuit.
Comply with all local electrical codes.
8.2 CABLE SELECTION
Waterproof 4 conductor SEO, or similar, type electrical cable must be used to connect
the aerator motor to the electrical control box when three phase power is used. Three
wire cable is recommended for single phase power. Refer to the electrical cable
selection chart at the end of this manual, to determine proper wire size.
8.3: ELECTRICAL ACCESSORIES
Connect the electrical cable to the aerator motor following the wiring diagram inside the
motor junction box cover or on the motor nameplate. If illegible, the wiring diagram
can be found at the motor manufacturer’s website.
Wiring diagrams for DOL (Direct On Line) and Delta change from model
to model. Incorrectly wiring a motor will seriously damage the motor
and void the warranty.
Make sure a proper ground is always provided and securely attached to
the motor grounding lug. Failure to do so will void the motor warranty
and could cause serious injury.
A watertight cable grip (
FIGURE 14)
should be used to affix the electrical cable to the
motor junction box. This clamp is available from AEROMIX as an option, or can be
supplied by your electrician. Support the electrical cable in a way which provides slack
to allow the aerator to be adjusted in its mounting cradle.
Make sure the electrical cable is secure well away from the aerator propeller.
After installation, check that the proper voltage is being provided a check for continuity
of the ground.
