2.1 Components

• Actuator Body: Contains the motor and gear mechanism.
• Linear Rod: Extends and retracts to provide linear motion.
• Mounting Brackets: For secure attachment to the bed frame.
• Power Cable: With a 2-pin connector for power supply.
• Remote Port Cable: With a 4-pin connector for remote control integration.

3. Setup and Installation

Important: Before beginning installation, ensure the adjustable bed is unplugged from the power source. Always verify that the replacement actuator matches the specifications and connector types of your original actuator.

3.1 Pre-Installation Checks

1. Confirm the model number on your existing actuator is HJA35.
2. Verify that your bed's power supply and remote control connections are compatible with the 2-pin power connector and 4-pin remote port of the new actuator.
3. Ensure the bed frame is stable and clear of obstructions.

3.2 Installation Steps

1. Disconnect Power: Unplug the adjustable bed from the wall outlet.
2. Remove Old Actuator: Carefully detach the old actuator from its mounting points on the bed frame. Disconnect its power and remote cables.
3. Mount New Actuator: Position the new HJA35 actuator in the same location as the old one. Securely attach it using the existing mounting hardware. Ensure all connections are firm and stable.
4. Connect Cables: Connect the 2-pin power cable from the actuator to the bed's power supply. Connect the 4-pin remote port cable to the bed's remote control system. Ensure connectors are fully seated.
5. Cable Management: Route cables neatly to prevent pinching or entanglement during bed operation.
6. Test Functionality: Plug the adjustable bed back into the power outlet. Test all functions of the bed (head up/down, foot up/down) using the remote control to ensure the actuator operates smoothly and correctly.

4. Operating Instructions

The Richmat HJA35 actuator functions as a component within your adjustable bed system. Its operation is controlled directly by the bed's remote control unit.

4.1 Basic Operation

• Use the designated buttons on your adjustable bed's remote control to extend or retract the actuator, thereby adjusting the position of the bed sections (e.g., head or foot).
• The actuator will move the bed section until the button is released or the maximum/minimum extension limit is reached.

4.2 Duty Cycle

The HJA35 actuator has a duty cycle of 10%, Max. 2min ON/18min OFF. This means the actuator can operate continuously for a maximum of 2 minutes, after which it requires an 18-minute rest period to prevent overheating and ensure longevity. Adhering to this duty cycle is critical for the actuator's performance and lifespan.

5. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your Richmat HJA35 actuator.

5.1 Cleaning

• Periodically wipe down the exterior of the actuator with a dry, soft cloth to remove dust and debris.
• Do not use liquid cleaners or solvents, as these can damage internal components.

5.2 Inspection

• Regularly inspect the power cable and remote port cable for any signs of wear, fraying, or damage.
• Check the mounting points to ensure the actuator remains securely fastened to the bed frame.
• Listen for any unusual noises during operation, which could indicate an issue.

Note: The actuator is not designed to be opened or serviced by unauthorized personnel. Attempting to open the unit will void any warranty and may result in damage or injury.

6. Troubleshooting

If you encounter issues with your Richmat HJA35 actuator, refer to the following common troubleshooting steps.

6.1 Actuator Not Responding

• Check Power: Ensure the adjustable bed is securely plugged into a working electrical outlet.
• Check Connections: Verify that the 2-pin power connector and 4-pin remote port connector are fully and securely seated in their respective ports.
• Remote Control: Ensure the remote control has working batteries and is functioning correctly. Try re-pairing the remote if applicable to your bed model.
• Overheat Protection: If the actuator has been used continuously, it may have entered its thermal protection mode. Allow it to cool down for at least 18 minutes before attempting operation again.

6.2 Actuator Makes Unusual Noises

• Obstructions: Check for any objects or debris that might be obstructing the movement of the bed mechanism or the actuator itself.
• Mounting: Ensure the actuator is securely mounted and not loose, which could cause rattling.

If the issue persists after performing these checks, contact customer support for further assistance.
