This document serves as an instruction manual for the Toshiba MM-EM25P(WH) microwave oven, providing comprehensive guidance on its safe operation, installation, usage, and maintenance.
Product Safety
The manual begins with crucial safety instructions to minimize risks such as fire, electric shock, injury, and exposure to excessive microwave energy. Users are advised to read and follow specific precautions regarding microwave energy exposure and to ensure the appliance is used safely, especially around children. It emphasizes that children should not play with the appliance and that cleaning and user maintenance should only be performed under supervision. The supply cord, if damaged, must be replaced by the manufacturer or a qualified service agent. A warning is issued regarding lamp replacement, stressing that the appliance must be switched off to avoid electric shock. Furthermore, it highlights the danger of anyone other than a competent person carrying out service or repair operations that involve removing covers that protect against microwave energy exposure.
Liquids and other foods should not be heated in sealed containers due to the risk of explosion. When heating food in plastic or paper containers, constant supervision is necessary to prevent ignition. Only microwave-safe utensils should be used. In case of smoke, the appliance must be switched off or unplugged, and the door kept closed to stifle flames. Microwave heating of beverages can lead to delayed eruptive boiling, requiring careful handling of containers. Contents of feeding bottles and baby food jars must be stirred or shaken, and their temperature checked before consumption to prevent burns. Eggs in their shell and whole hard-boiled eggs should not be heated in microwave ovens as they may explode. Regular cleaning of the oven and removal of food deposits are essential to prevent surface deterioration, which could adversely affect the appliance's lifespan and create hazardous situations. If a temperature probe is provided, only the recommended one should be used. The microwave oven should not be placed in a cabinet unless specifically tested for such installation.
The appliance is intended for household and similar applications, including staff kitchen areas, hotels, motels, farmhouses, and bed and breakfast environments. It is designed for heating food and beverages; drying food or clothing, or heating warming pads, slippers, sponges, and damp cloths can lead to injury, ignition, or fire. Metallic containers are not permitted during microwave cooking. The appliance should not be cleaned with a steam cleaner and is intended for freestanding use, with its rear surface placed against a wall. It is not designed to be operated by an external timer or separate remote-control system.
Product Introduction
The manual provides precautions to avoid possible exposure to excessive microwave energy. Users are warned against operating the oven with an open door, as this can result in harmful exposure. It is crucial not to break or tamper with safety interlocks. No objects should be placed between the oven front face and the door, and soil or cleaner residue should not accumulate on sealing surfaces. If the door or door seals are damaged, the oven must not be operated until repaired by a competent person. An addendum notes that failure to maintain cleanliness can degrade the apparatus's surface, affecting its lifespan and potentially leading to dangerous situations.
Grounding Installation
To reduce the risk of injury, proper grounding installation is emphasized. Touching internal components can cause serious injury or death, so users are warned not to disassemble the appliance. Improper use of grounding can result in electric shock, and the appliance should not be plugged into an outlet until properly installed and grounded. The appliance is equipped with a grounding wire and plug, which must be connected to a properly installed and grounded outlet. A qualified electrician or serviceman should be consulted if grounding instructions are unclear. If an extension cord is necessary, only a 3-wire grounding-type extension cord should be used, with an electrical rating at least as great as the appliance's. The cord should be arranged to prevent it from draping over countertops where it could be pulled by children or tripped over.
Cleaning
Cleaning instructions are provided to maintain the appliance. Users must unplug the appliance before cleaning. The oven cavity should be cleaned with a slightly damp cloth after each use. Accessories should be cleaned in soapy water. The door frame, seal, and surrounding parts require careful cleaning with a damp cloth. Harsh abrasive cleaners or sharp metal scrapers should not be used on the oven door glass to avoid scratching and shattering. A cleaning tip suggests placing half a lemon in a bowl with 300ml of water and heating it on 100% microwave power for 10 minutes to easily clean cavity walls, then wiping with a soft, dry cloth.
Utensils
The manual includes a section on suitable and unsuitable utensils for microwave use. A caution warns that only competent persons should perform service or repair operations involving the removal of covers that protect against microwave energy exposure. For non-metallic utensils, a test procedure is provided: fill a microwave-safe container with 1 cup (250ml) of cold water along with the utensil, cook on maximum power for 1 minute, and if the empty utensil feels warm, it is not safe for microwave cooking. The cooking time for this test should not exceed 1 minute.
A table lists materials that can be used in a microwave oven:
- Browning dish: Follow manufacturer's instructions; the bottom must be at least 3/16 inch (5mm) above the turntable.
- Dinnerware: Microwave-safe only; do not use cracked or chipped dishes.
- Glass jars: Remove lids; use only to heat food until warm, as most are not heat resistant.
- Glassware: Heat-resistant oven glassware only; ensure no metallic trim and no cracked or chipped dishes.
- Oven cooking bags: Follow manufacturer's instructions; do not close with metal ties; make slits for steam.
- Paper plates and cups: For short-term cooking/warming only; do not leave unattended.
- Paper towels: Use to cover food for reheating and absorbing fat; use with supervision for short-term cooking.
- Parchment paper: Use as a cover to prevent splattering or a wrap for steaming.
- Plastic: Microwave-safe only; follow manufacturer's instructions; "Microwave Safe" label recommended. Some plastic containers may soften; "boiling bags" and tightly closed plastic bags should be slit, pierced, or vented.
- Plastic wrap: Microwave-safe only; use to cover food to retain moisture; do not allow it to touch food.
- Wax paper: Use as a cover to prevent splattering and retain moisture.
Materials to be avoided in a microwave oven include:
- Aluminum tray: May cause arcing; transfer food to a microwave-safe dish.
- Food carton with metal handle: May cause arcing; transfer food to a microwave-safe dish.
- Metal or metal-trimmed utensils: Metal shields food from microwave energy and metal trim may cause arcing.
- Metal twist ties: May cause arcing and fire.
- Paper bags: May cause fire.
- Plastic foam: May melt or contaminate liquid when exposed to high temperature.
- Wood: Will dry out, split, or crack.
