4. Setup
- Unpack: Carefully remove the power supply from its packaging. Inspect for any visible damage.
- Battery Installation (Optional for Backup):
- Locate the battery compartment on the underside of the power supply (refer to Figure 2.3).
- Remove the battery compartment cover.
- Insert two 9-volt batteries, ensuring correct polarity (+/-).
- Replace the battery compartment cover securely.
- Note: Batteries are for backup power only and are not required for normal operation. They allow the chair to retract to a seated position during a power outage.
- Connect to Motor: Locate the two-pin power cable from your lift chair motor. Connect this cable to the corresponding DC output port on the power supply (refer to Figure 2.5). Ensure a firm connection.
- Connect to Wall Outlet: Plug the AC power cord (not always included, typically uses a standard figure-8 connector) into the AC input port on the power supply (refer to Figure 2.4). Then, plug the other end of the AC power cord into a standard 120V AC wall outlet.
- Verify Power: The "DC Power" indicator light on the top of the unit (refer to Figure 2.1) should illuminate, indicating that the power supply is receiving power and is ready for operation.
5. Operating Instructions
Once the power supply is correctly connected and powered, your lift chair should function normally using its standard controls. The power supply continuously provides the necessary DC voltage to the chair's motor.
- Normal Operation: Use your lift chair's hand control to recline, lift, or adjust the chair's position as usual.
- Battery Backup Use: In the event of a power outage, the installed 9-volt batteries will provide temporary power to allow the chair to return to a seated position. This feature is designed for emergency retraction, not continuous operation.
6. Maintenance
- Cleaning: Keep the power supply clean and free from dust. Wipe with a dry, soft cloth. Do not use liquid cleaners.
- Ventilation: Ensure the power supply is placed in a well-ventilated area to prevent overheating. Do not cover it.
- Battery Replacement: If using the battery backup feature, check the 9-volt batteries periodically (e.g., every 6-12 months) and replace them if they are depleted or if the backup function does not work during a power interruption.
- Cable Inspection: Regularly inspect all cables and connections for signs of wear, fraying, or damage. Replace any damaged cables immediately.
