4. Safety Information
- Always ensure the power is off before installation or maintenance.
- Do not exceed the maximum connectable length of 200FT (4 strands).
- Use only with 120V power outlets.
- Ensure all connections are secure and waterproof caps are tightened for outdoor use.
- Keep bulbs and electrical components away from flammable materials.
- Do not attempt to modify the product in any way.
- The bulbs are shatterproof plastic, but handle with care to avoid damage.
5. Setup and Installation
Follow these steps to set up your VASTFIRE string lights:
- Unpack Components: Carefully remove all items from the packaging. Inspect for any damage.
- Bulb Installation: Gently screw each S14 LED bulb into its respective E26 socket on the string. Ensure they are finger-tight to prevent moisture ingress.
- Planning Placement: Determine the desired layout for your lights. Each strand is 50FT long, with a 9FT lead from the plug to the first bulb, 1.5FT spacing between bulbs, and a 1FT tail cord.
- Mounting: Use the provided zip ties and screw hooks to secure the string lights. The integrated loops on each socket allow for easy hanging. For best results, ensure the string is taut but not overly strained.
- Connecting Multiple Strands: If using multiple strands, connect them end-to-end using the waterproof connectors. Twist the connectors securely to ensure a watertight seal. You can connect up to 4 strands for a total of 200FT.
- Power Connection: Plug the string lights into a standard 120V outdoor-rated power outlet.

- Verify the outlet is receiving power.
- Ensure the remote control batteries are functional and the remote is pointed towards the receiver.

- Remote Not Responding:
- Replace the remote control batteries.
- Ensure there are no obstructions between the remote and the light string's receiver.
