CLEANING THE OVEN
On the stainless exterior, deposits of baked on splat­ter may be removed with any of the following ele­ments: Grade FFF Italian Pumice, Liquid Nu Steel, Permapass, Samea or Cameo paste, Nu Steel, or Du­Bois Temp. Heat tint and heavy discoloration may be removed with one of the following: Penny-Brite, Copper-Brite, DuBois Temp., Paste Nu Steel, 5 to 15% phosphori c acid. Apply cleaners when the oven is cold, and always rub with the grain of the metal. The racks and rack supports may be cleaned by re­movingthem from the oven and soaking them in a so­lution of ammonia and water.
Care should be taken to keep liquids away from tem­perature probes, heating elements etc. and avoid spraying the oven’s electrical connections and ther­mostat.
PREVENTATIVE MAINTENANCE
The best preventative maintenance measures are, the proper installation of the equipment and a pro­gram for routinely cleaning the ovens. This oven re­quires no lubrication, however, the venting system should be checked annually for possible deteriora­tion. If maintenance or repairs are required, they
should only be performed by qualified service per­sonnel.
Remember: Always disconnect the power supply be­fore cleaning or servicing the appliance!
