How to use
To use the Deltaco 665-U, align the coupler with the two corresponding standard sockets or plugs and insert firmly until a secure fit is achieved.

After installation, check the connection for stability and that no excessive heat is generated during initial use. Disconnect by pulling the coupler straight out without twisting, keeping fingers clear of contact points.
Usage recommendations
Use the coupler only with compatible standard sockets and within the rated electrical limits of the connected devices. Avoid exposure to water, high humidity, or extreme temperatures. If the coupler becomes damaged, shows signs of overheating, or the fit becomes loose, discontinue use and replace it. For fixed or high-load installations, consult a qualified electrician to ensure safe and correct use.
