APISQUEEN U92 Pro Underwater Thruster User Manual

1. Introduction

The APISQUEEN U92 Pro is a newly upgraded underwater thruster designed for various marine applications, including fishing boats and inflatable boats. It features an external rotor design to prevent sand ingress, delivers high torque with low power consumption, and offers enhanced energy efficiency and reduced energy usage. This manual provides essential information for the safe and effective use of your U92 Pro thruster.

2. Safety Information

⚠ WARNING: This product can expose you to chemicals including phthalates (DEHP), which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.

• Always ensure proper insulation and secure connections for all wiring to prevent electrical hazards.
• The maximum operating voltage for the thruster must not exceed 29V. Exceeding this voltage can cause severe damage to the unit and pose a safety risk.
• When operating the thruster, ensure that the thruster wires are not too loose. Excessive slack can cause the wires to be drawn into the thruster, leading to damage to the unit and potential entanglement.
• Keep hands, loose clothing, and other objects clear of the propeller during operation to prevent injury.
• Do not operate the thruster out of water for extended periods, as this can lead to overheating and damage.

3. Package Contents

Depending on the purchased variant, your package should include the following:

• APISQUEEN U92 Pro Underwater Thruster (with or without integrated ESC)
• Remote Control (if purchased as a kit)
• Necessary wiring for connection

Please inspect all components upon receipt and contact your vendor immediately if any items are missing or damaged.

5. Setup Instructions

Follow these steps to properly set up your U92 Pro Underwater Thruster:

5.1. Wiring the Thruster (if ESC is separate)

1. Connect the thruster's three-phase wires to the ESC (Electronic Speed Controller) in any order.
2. If the thruster rotates in the wrong direction during initial testing, simply swap the order of any two wires to reverse the rotation.

5.2. Connecting the ESC to the Receiver

1. Insert the ESC signal wire (ensure the copper-plated side is facing right) into channel 1 or channel 2 of your receiver.
2. Note: This ESC model features a built-in BEC (Battery Eliminator Circuit), which provides 5V power to the receiver. If you are using an ESC without a built-in BEC, an external UBEC (Universal Battery Eliminator Circuit) must be connected to supply power to the receiver.

5.3. Power Connection

1. Connect the power supply or battery to the device.
2. Important: The maximum voltage for the power supply must not exceed 29V.

6. Operation

Once the thruster is properly set up and connected:

1. Turn on the remote control.
2. Submerge the thruster in water.
3. Push the joystick on the remote control to rotate the thruster.
   • Push the joystick up to move the thruster forward.
   • Pull the joystick down to move the thruster backward.
4. When not in use, first disconnect the battery or power source from the thruster, then turn off the remote control.

7. Maintenance

To ensure the longevity and optimal performance of your U92 Pro thruster, follow these maintenance guidelines:

• Cleaning: After each use, especially in saltwater, rinse the thruster thoroughly with fresh water to remove any salt, sand, or debris.
• Inspection: Regularly inspect the propeller for any signs of damage, entanglement (e.g., fishing line, weeds), or wear. Ensure the external casing is intact and free from cracks.
• Wiring: Check all electrical connections for corrosion or damage. Ensure wires are securely fastened and not loose, which could lead to them being sucked into the thruster.
• Storage: Store the thruster in a clean, dry place away from direct sunlight and extreme temperatures.
• The U92 Pro is designed with an external casing process suitable for long-term immersion in water and is resistant to mud and sand, reducing the need for frequent deep cleaning of internal components.

8. Troubleshooting

9. User Tips

• Power and Performance: Users have noted the U92 Pro's powerful thrust (over 10 kg) and quiet, smooth operation. For heavier loads or larger boats (e.g., a 2-person, 250kg inflatable boat), the 24V version is recommended for its higher thrust capabilities.
• Durability: The thruster's robust casing and external rotor design provide excellent protection against water and sand, making it suitable for long-term immersion and use in challenging marine environments. It resists overheating even after prolonged use.
• CW vs. CCW: The choice between CW (Clockwise) and CCW (Counter-Clockwise) thrusters typically depends on your specific setup and desired direction of rotation, especially when using multiple thrusters. If you are using a single thruster, the direction can be reversed by swapping two of the three-phase wires if needed.
• Energy Efficiency: The U92 Pro is designed to be energy-efficient, consuming less power while delivering high performance.
