Installation & Assembly

Included Components

The assembly includes the float platform, motor assembly, stainless steel debris shield, and three self-tapping screws. The assembly instructions call for a 3/8-inch wrench or socket screwdriver and two 1/2-inch wrenches or pliers.

Weighted Anchoring

Two 3/8-inch or thicker nylon anchoring lines attach to the unit's two eyebolts. For weighted anchoring, the lines extend outward approximately 25 feet at a 45-degree angle. The weighted anchors are positioned on the pond bottom at least 25 feet apart. Anchor weights are not included.

Shoreline Anchoring

The DA-20 can also be anchored from shore using two 3/8-inch or thicker nylon lines. The manufacturer recommends auger-style earth anchors or posts for shoreline anchoring. Anchoring ropes and shoreline anchors are not included.

Electrical Installation

A GFCI is required for operation, and Scott Aerator recommends using a licensed electrical contractor. The manufacturer specifically states that an extension cord should not be used to supply power to the motor. Proper cable sizing is important to maintain safe operating conditions and protect the motor.

Maintenance & Winter Operation

Routine Maintenance

The DA-20 requires very little routine maintenance under normal operating conditions. Scott Aerator recommends changing the propeller assembly about every five years and replacing quality nylon anchoring rope at five-year intervals when 3/8-inch or thicker rope is used.

Cleaning & Inspection

When the unit is removed from the water for service, wash it with high-pressure water and visually inspect the aerator to make sure debris or other material is not restricting water flow.

Winter Operation

The DA-20 is designed to remain in the water throughout winter. Scott Aerator recommends turning off the power supply during freezing conditions rather than removing the aerator. Once the water thaws in spring, restore power to the unit. The components are designed to withstand sub-zero conditions without damage.

Warranty

5-Year Motor Warranty

Standard Scott Aerator products are unconditionally warranted for five years against motor defects in materials or workmanship under normal operating conditions.

Other product components are covered by a 1-year warranty from the date of purchase, subject to the manufacturer's warranty terms.
