4. Installation

Before beginning installation, ensure you have identified the correct replacement motor by checking the label on your existing motor. Verify that the power supply and hand control are functioning correctly before replacing the motor itself.

Installation Steps:

1. Disconnect Power: Unplug the recliner or lift chair from the main power outlet.
2. Access Motor: Carefully position the furniture to access the existing motor. This may involve tilting the chair or removing a fabric cover.
3. Disconnect Cables: Disconnect the 2-pin flat round power transformer connection and the 5-pin hand control plug connection from the old motor.
4. Remove Old Motor: Detach the old motor from the chair frame. This typically involves removing pins or bolts that secure the motor to the frame and the reclining mechanism. Note the orientation and mounting points.
5. Install New Motor: Position the new Fruhdi RMT Model R8112 motor in the same location and orientation as the old motor. Ensure the minimum install size of 375mm (14.76 inches) and stroke of 198mm (7.80 inches) are compatible with your furniture's mechanism. Secure the motor to the chair frame using the provided pins or original hardware. Ensure it is firmly attached and does not wobble.
6. Connect Cables: Connect the 2-pin flat round power transformer cable to the corresponding port on the new motor. Connect the 5-pin hand control plug to its designated port. Ensure all connections are snug and secure.
7. Test Functionality: Before fully reassembling the furniture, plug the chair back into the power outlet. Carefully test the recliner's movement using the hand control to ensure the motor operates smoothly and correctly through its full range of motion.
8. Final Assembly: Once confirmed operational, reassemble any covers or components removed during installation.

Note: If the chair does not operate correctly after installation, refer to the Troubleshooting section.

5. Operation

The Fruhdi RMT Power Recliner Motor Actuator operates in conjunction with your furniture's existing hand control remote and power supply. Once installed and connected, the motor will respond to commands from the hand control to extend or retract the linear shaft, thereby moving the reclining mechanism.

• Ensure the chair is plugged into a functional power outlet.
• Use the buttons on your hand control remote to initiate reclining or lifting actions.
• Release the button when the desired position is reached.
• Avoid forcing the mechanism if it encounters an obstruction.

6. Maintenance

The Fruhdi RMT Power Recliner Motor Actuator is designed for minimal maintenance. Regular care can help ensure its longevity and smooth operation.

• Cleaning: Periodically wipe the exterior of the motor and accessible parts of the linear shaft with a clean, dry cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
• Inspection: Occasionally inspect the motor and its connections for any signs of wear, damage, or loose wiring. Ensure mounting pins and bolts remain secure.
• Lubrication: The internal components of the motor are factory-lubricated and generally do not require additional lubrication. If the linear shaft appears dry or sticky, a small amount of silicone-based lubricant can be applied to the exposed shaft, avoiding the motor housing.

7. Troubleshooting

If your recliner or lift chair is not operating correctly after motor replacement, perform the following checks:

• No Movement:
  • Ensure the chair is securely plugged into a live electrical outlet.
  • Check all cable connections to the motor, power transformer, and hand control. Ensure they are fully inserted and secure.
  • Verify that the power supply unit (transformer) is receiving power and functioning correctly. Some transformers have indicator lights.
  • Test the hand control remote. If possible, try a known working remote or inspect the remote's cable for damage.
• Intermittent Movement or Unusual Noises:
  • Inspect the motor's mounting points. Ensure it is securely fastened and not loose.
  • Check for any obstructions in the reclining mechanism that might be impeding the motor's movement.
  • Ensure the linear shaft is clean and moves freely.
• Motor Overheating:
  • Avoid continuous operation for extended periods. Allow the motor to cool down between uses.
  • Ensure there are no obstructions causing the motor to work harder than necessary.

If troubleshooting steps do not resolve the issue, it may indicate a fault with the motor, power supply, or hand control. Contact the manufacturer or a qualified technician for further assistance.
