• Charging: Follow the instructions provided with your EV charging unit to initiate and monitor the charging process.
• Disconnecting: When charging is complete, or if you need to disconnect, firmly grasp the plug and pull it straight out from the receptacle. Avoid pulling by the cable.

Note: While designed for frequent use, it is recommended to avoid unnecessary plugging and unplugging to maintain optimal terminal contact over time.

7. Maintenance

Regular inspection and minimal maintenance will ensure the longevity and safe operation of your Leviton 1450R receptacle.

• Periodic Inspection: Periodically inspect the receptacle for any signs of damage, discoloration, or loose connections. If any issues are observed, disconnect power and consult a qualified electrician.
• Cleaning: Ensure power is OFF before cleaning. Wipe the surface of the receptacle with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Temperature Monitoring: During extended charging sessions, occasionally check the receptacle and plug for excessive heat. While some warmth is normal, excessive heat may indicate a problem. If you detect excessive heat, discontinue use and consult an electrician.
