4. Setup and Installation

Before installing the new actuator, it is crucial to verify the compatibility and functionality of your existing recliner components. Always troubleshoot the switch/remote or power supply before replacing the motor.

4.1 Pre-Installation Checks

• Verify Model Number: Ensure the model number on your existing actuator matches 3MTRE 3MRE157-200T.
• Power Supply: Confirm your power supply is functioning correctly and matches the required specifications (DC29V 2A).
• Hand Control/Switch: Test your hand control or switch for proper operation.

4.2 Installation Steps

1. Disconnect Power: Unplug the recliner from the main power outlet.
2. Remove Old Actuator: Carefully detach the old actuator from the recliner frame. Note the orientation and connection points.
3. Mount New Actuator: Secure the new Uetmulik Emomo actuator to the recliner frame using appropriate hardware. Ensure it is firmly attached and aligned correctly.
4. Connect Cables: The actuator features three distinct cable connections:
   • Power Supply Connection: Connect the 2-pin flat round female connector from the actuator to your recliner's power transformer.
   • Head Motor Connection: Connect the 2-pin flat round male connector to the head motor (if applicable).
   • Hand Control Connection: Connect the 5-pin female connector to your recliner's hand control unit.
5. Secure Connections: Ensure all plugs are fully inserted and secure.
6. Restore Power: Plug the recliner back into the main power outlet.
7. Test Functionality: Test the recliner's movement using the hand control to ensure the actuator operates smoothly in both directions.

5. Operating Instructions

Once installed, the Uetmulik Emomo actuator operates in conjunction with your recliner's existing hand control. Pressing the appropriate buttons on your hand control will extend or retract the actuator, moving the recliner mechanism.

• Operate the recliner smoothly, avoiding sudden or forceful movements.
• Adhere to the specified duty cycle of 1 minute ON / 8 minutes OFF to prevent motor overheating. Allow the motor to cool down if it has been in continuous operation.
• Do not attempt to manually force the recliner mechanism while the actuator is engaged.

6. Maintenance

Regular maintenance helps ensure the longevity and reliable operation of your actuator.

• Cleaning: Keep the actuator and its moving parts free from dust, dirt, and debris. Use a dry, soft cloth for cleaning. Avoid using harsh chemicals or abrasive cleaners.
• Connection Checks: Periodically inspect all cable connections to ensure they remain secure and free from damage.
• Lubrication: The internal components are pre-lubricated. Do not attempt to lubricate the internal mechanism unless specifically instructed by a qualified technician.
• Environmental Conditions: Ensure the actuator is not exposed to excessive moisture, extreme temperatures, or corrosive environments.

7. Troubleshooting

If your recliner is not functioning correctly after actuator replacement, perform the following troubleshooting steps:

1. No Movement:
   • Check if the recliner is properly plugged into a working power outlet.
   • Verify that the 2-pin power supply connector is securely attached to the power transformer.
   • Inspect the power supply unit itself for any signs of damage or malfunction.
   • Ensure the 5-pin hand control connector is fully inserted and the hand control is functional.
2. Partial Movement or Intermittent Operation:
   • Check all cable connections for looseness or damage.
   • Ensure the actuator is not obstructed by any part of the recliner mechanism or external objects.
   • Allow the motor to cool down if it has been operating continuously for an extended period, as it may have reached its duty cycle limit.
3. Unusual Noises:
   • Disconnect power and inspect the actuator for any foreign objects or damage to the moving parts.
   • Ensure the actuator is correctly mounted and not rubbing against the recliner frame.

If issues persist after performing these troubleshooting steps, contact the seller or a qualified technician for further assistance.
