NOTICES There are three different types of notices that you should be familiar with, a NOTICE, CAUTION, and WARNING. A NOTICE is a special note used to call attention to a particularly important point. CAUTION is used to point out a procedure or operation which may cause equipment damage. The WARNING notice is the most important of the three because it warns of an operation that may cause personal injury.
SAFETY SAFETY SAFETY SAFETY SAFETY WARNING The fryer may be equipped with an oil proof, electrical supply cord with a three prong safety plug. This is to protect operators from electrical shock hazard in the event of an equipment malfunction. DO NOT cut or remove the grounding (third) prong from this plug. WARNING There is an open flame inside the fryer. The unit may get hot enough to set near by materials on fire. Keep the area around the fryer free from combustibles.
SAFETY SAFETY SAFETY SAFETY SAFETY WARNING Ensure that the fryer can get enough air to keep the flame burning correctly. If the flame is starved for air it can give of a dangerous carbon monoxide gas. Carbon Monoxide is a clear odorless gas that can cause suffocation. WARNING If your appliance operates on line voltage, the power supply must be disconnected before servicing or cleaning the appliance. WARNING The fryer must be properly restrained to prevent movement or tipping.
