There are a few things to keep in mind prior to cookin' like a pro:
• Electrical connections and any other work must be performed by Anova certified personnel only
• Always turn off and unplug the unit
• Make sure system is at room temperature
Disconnect circulator from power source. Check for signs of damage including pulled cord or physical damage to system or heaters. If any signs of physical damage are found send back for factory service and replacement parts.
