5. GE 1 Safety Precautions VAN Read Operating Instructions Thoroughly Prior to Operation A The AFE Series lab ovens are not designed for use with any flammable solvents or gases or for materials that may contain flammable solvents or gases Use only a grounded outlet that is rated for your model s electrical requirement Oven exterior walls and doors may become hot to the touch when operating at higher set temperatures Do not leave the oven unattended during operation especially when processing materials that have flash point temperatures lower than the model oven s maximum operating range Do not modify the oven or control parameters to operate the oven above the stated maximum operating temperature TSR Set up A iy a d Position unit in its ultimate operating location Keep a minimum of 2 of airspace around the unit and a minimum of y 10 above the unit Important The exhaust ports should NOT be used as chamber access for temperature measuring ee probes Insertion of any such probe or device Me damage AREA i or unbalance the circulating fan blade at the top of the oven CO h f chamber Ww f Install adjustable shelf by placing the ends of the wire shelf bracket into the corresponding holes located on the inner sides of the oven at the desired height Push the ends of the bracket into the holes until the first bends in the bracket are against the wall then rotate the bracket down Place the shelf on the brackets FIG 1
