II. SAFETY INSTRUCTIONS The Hobart oven complies with all relevant safety standards. However, it doesn’t eliminate any risk such as the ones resulting from a unauthorised practices and usage of the oven. The operators should also respect the following instructions. Non authorised maintenance or cleaning and modifications made to the unit by non qualified technicians may cause a definitive failure of the oven and pose risk of injury to the operator. Please read carefully the instruction manual and ensure suitable training is undertaken for all persons who will be using the oven. Make sure that the installation, the maintenance and the modifications to the unit are appropriate and made by qualified technicians. Environnement Do not use the unit in a toxic or explosive environment. Do not use the oven if the temperature is below 4 C. Some components might be damaged. If the oven has been moved from a cold place (plane hold, ware house, etc, ) to its installation location, wait untill the oven has reached the ambient temperature before turning on the electrical supply. Do not store gas or flammable liquids near the oven. They would be a potential fire hazard due to the heat generated in operating the oven. Avoid placing the oven near equipment using hot oil (fryers etc). Water spilt or transferred onto hot oils/greases presents a high risk of burn. Handling Wear suitable gloves or other protective means to remove cooking utensils (pans, trays, core temperature probes ) from the oven cavity as it is cooking. Caution: They may be very hot. Remove the core temperature probe from the food before removing them from the cavity. Do not let the core temperature probe hang. Store it inside the storage compartment in the front cabinet below the display. When using pans containing liquids or food giving a lot of liquid while cooking, use the racks which below 1.6M height as identified to avoid the risk of over spillage and burns. Cooking Do not heat up flammable products. If you have to open the door during cooking, it is recommended to slightly open it to let steam escape and the fully open. This would avoid potential risks of steam or heat contact which could cause burns when a big quantity of steam escapes from the cavity. Do not watch inside the vent pipe nor leave the hand above it. Evacuated steam/heat at the same temperature of the cavity may be evacuated there. Maintenance Isolate the mains services before undertaking any service operations and before opening of the side panel(s) or of the display board. If you notice that one of the door glass is damaged (scratch, notch, cracks ), have it changed immediately. It might break if you were using it. It is very important to descale your oven to ensure optimal and secure operation of your oven. Your water consumption will thus be even lower than the rate of scale formation will be low.
