1. Place the submerged unit of the oil skimmer at the location where floating oil accumulates in the oil-water separator. Adjust the four adjustable floats to ensure the unit remains level, and position the top surface of the oil collection cylinder 10–30 mm below the oil surface.
2. Place the surface unit of the skimmer on the ground adjacent to the separator, as close as possible to the submerged unit. Ensure it is level and stable, and verify that its elevation does not exceed the suction lift limit of the oil pump.
3. Connect the control box power cable to the main power supply and connect the power cables for the oil collection motor and the oil pump motor. The power cable for the oil collection motor must be a three-phase, four-wire cable with black rubber insulation to prevent electrical leakage.
4. Start the oil collection motor and observe whether the oil on the surface is being drawn into the collection cylinder. If not, adjust the wiring connections to ensure the motor rotates in the correct direction for proper oil collection.
5. Connect the thick-walled, oil-resistant rubber hose between the vacuum tank and the oil collection cylinder. Connect the pipe fitting on the clean water overflow trough to the separator using a standard rubber hose or galvanized steel pipe; the discharge end should be submerged 300–500 mm below the liquid surface to avoid disturbing the oil layer on the pool surface.
6. Open the air release valve on the vacuum tank and fill the tank with tap water or clean water from the separator using the priming funnel; then, close the valve tightly. The vacuum tank enables continuous oil extraction by creating negative pressure during pump operation. There is no need to refill the tank with water before restarting the pump.
7. Start the oil collection motor and let it run for a few minutes before starting the oil pump. Once the secondary separation tank is full, clean water will discharge from the overflow trough's hose fitting, and floating oil will slowly overflow from the oil discharge pipe.
8. To enhance oil removal efficiency, adjust the control nut to regulate the thickness of the oil layer based on the quality of the oil overflowing from the discharge pipe.
