• This oven contains no user-serviceable parts. Any repairs should be performed by an authorized service representative.

1. Before cleaning, cancel cooking and unplug the oven, then allow it to cool completely. Open the door for faster cooling.
2. Apply non-abrasive liquid cleanser or a mild spray solution to a soft, damp cloth or sponge (not directly on the oven surface) and wipe all parts of the oven, especially the oven interior.

Note: Do not use a dry cloth on the display screen, or it may be scratched.

3. To clean the glass door, use a glass cleaner or mild detergent and a soft, damp sponge or soft, plastic scouring pad.
4. Let all surfaces dry completely before plugging in or starting the oven.

Cleaning the Burner

• Apply a ceramic cooktop cleaner to the burner surface before using and whenever the surface is dirty.
• If any food spills on the burner surface, immediately use a metal razor scraper to remove the food or burned-on residue. This is more effective if the cooktop is still warm.
  

1. Do not use a dull or nicked blade.
2. Hold the scraper at about a 30° angle to the cooktop.
3. If used correctly, the metal scraper will not damage the surface.

• If water spills on the burner surface, wipe it immediately with a dry paper towel.

• Spills with sugar (such as preserves, ketchup, jellies, etc.) or melted plastic may cause pitting on the surface of the cooktop.
• Spills with food or water containing calcium (such as baking powder, wine, milk, spinach, etc.) may permanently stain or discolor the cooktop.

Cleaning the Accessories

• Apply non-abrasive liquid cleanser or a mild spray solution to a soft, damp sponge or soft, plastic scouring pad (not directly on the accessory surface). Wipe accessories and soak in warm, soapy water if necessary.
  1. To extend the life of the accessories, we do not recommend placing accessories in a dishwasher.
• To clean the splatter guard, soak it in a bowl with hot water and mild detergent.
  1. The splatter guard should be replaced when it is noticeably dirty or discolored (usually after 3 months, depending on oven usage).
• For stubborn grease:
  1. In a small bowl, mix 2 US tbsp / 30 mL of baking soda with 1 US tbsp / 15 mL of water to form a spreadable paste.
  2. Use a sponge to spread the paste on the trays and scrub. Let the trays sit for 15 minutes before rinsing.
  3. Wash trays with soap and water.
• Dry thoroughly.

Cleaning the Vents

• Use a vacuum cleaner with a brush or crevice attachment to clean the vents.
  
• Do not remove any panels from the oven.

Storage

1. Clean and dry the oven and all accessories.
2. Store the accessories in the oven. Make sure the oven door is closed.
3. Store the oven in an upright position.
   Do not store anything on top.

IMPORTANT SAFEGUARDS

READ AND SAVE THESE INSTRUCTIONS
Follow basic safety precautions when using your oven. Read all instructions.

Key Safety Points

• Do not touch hot surfaces. Use handle.
• The outside of the oven, including the door, is hot during and after use.
• The top and bottom heating elements (inside the oven) are hot during and after use.
• Always use heat-resistant gloves, pads, or oven mitts when handling hot materials, and when placing items in or removing items from the oven, including trays, racks, accessories, or containers.
• Steam may release from the sides of the door during cooking. This is normal. The door is vented to release steam created from cooking high moisture food, such as frozen bread.
• Water or condensation may build up and drip from under the door if you are cooking high moisture food. This is normal.
• Do not block any ventilation openings. Hot steam is released through openings. Keep your hands and face clear of openings.

General Safety

• When the oven is not in use, and before cleaning, unplug it from the outlet. Allow to cool completely before putting on or taking off parts.
• To protect against electric shock, do not immerse the oven, cord, or plug in water or liquid.
• Close supervision is necessary when the oven is used by or near children.
• Children should be supervised to ensure that they do not play with the oven.
• Do not use your oven if it is damaged, not working, or if the cord or plug is damaged.
  Contact Customer Support.
• Do not use third-party replacement parts or accessories, as this may cause injuries.
• Do not use outdoors.
• Do not place the oven or any of its parts on a stove, near gas or electric burners, or inside a heated oven.
• Be extremely cautious when removing a tray, basket, or rack if it contains hot oil, grease, or other hot liquids.
• Do not clean with metal scouring pads. Metal fragments can break off the pad and touch electrical parts, creating a risk of electric shock.
• Do not store anything on top of your oven while it is operating. Do not store anything inside your oven other than recommended accessories.
• The oven is not intended to be operated by means of an external timer or separate remote-control system.
• Only use as directed in this manual. Do not use oven for any purpose other than its intended use.
• This oven is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the oven by a person responsible for their safety.
• Do not allow children to clean or perform maintenance on the oven.
• Keep the oven and its cord out of reach of children.

Note: See Care & Maintenance for instructions on how to clean accessories.

While Cooking

• 
  To avoid risk of fire or electric shock, do not place oversized foods or metal utensils into the oven.
• Do not place paper, cardboard, or nonheat-resistant plastic into your oven, or any materials which may catch fire or melt.
• To avoid overheating, do not use metal foil in the oven unless directed. Use extreme caution when using foil, and always fit foil as securely as possible. If the foil contacts the oven's heating elements, this can cause overheating and risk of fire.
• Never put baking or parchment paper into the oven without food on top. Air circulation can cause paper to move and touch heating elements.
• Always use heat-safe containers. Be extremely cautious if using containers that aren't metal or glass.
• Keep your oven away from flammable materials (curtains, tablecloths, walls, etc.). Use on a flat, stable, heat-resistant surface away from heat sources or liquids.
• Immediately cancel cooking and unplug your oven if you see dark smoke coming out. Food is burning. Wait for smoke to clear before opening the oven door.
• When unplugging the oven, be cautious of hot surfaces.

Power & Cord

• This oven uses a short power-supply cord to reduce the risk of entangling or tripping.
• 
  To ensure continued protection against risk of electric shock, connect to properly grounded outlets only.
• Your oven has a 3-prong grounding plug, and should only be used with 120V, 60Hz electrical systems in North America. Always plug into a grounded electrical outlet. Do not modify the plug in any way.
• Do not let the power cord (or any extension cord) hang over the edge of a table or counter, or touch hot surfaces.
• The cord should be arranged so that it will not drape over the countertop or tabletop where it can be pulled on by children or tripped over unintentionally.
• To turn the oven off, press and hold . All the buttons will shut off except .
  Press and hold to turn the oven back on.
• 
  If the power supply cord is damaged, it must be replaced by Arovast Corporation or similarly qualified persons in order to avoid an electric or fire hazard. Please contact Customer Support.

Extension Cords

• Longer extension cords are available and may be used if care is exercised in their use.
• If a longer extension cord is used:
  • The marked electrical rating of the cord set or extension cord should be at least as great as the electrical rating of the oven.
  • The cord should be arranged so that it will not drape over the countertop or tabletop where it can be pulled on by children or tripped over unintentionally.
  • The extension cord should be a grounding-type 3-wire cord.
