This manual provides instructions for the Hamilton Beach 20L Manual Microwave. It is intended for domestic use only. Ensure the appliance is placed in a dry, non-corrosive area with adequate ventilation (10 cm at the back, 5 cm at the sides, and 20 cm above). Always ensure the appliance is properly earthed before use.
Product Overview
The microwave features a door lock, viewing window, rotating ring, rotating axis, turntable, control panel, waveguide cover, and a door release button. Refer to the diagram on page 6 for specific component locations.

Control Panel
The control panel consists of two main dials:

- Power Dial: Used to select the desired cooking power level (6 levels available).
- Timer Dial: Used to set the cooking duration, up to 30 minutes per session.
Turning the power dial clockwise increases the power level. Power levels range from Low (20%) to High (100%).
Using Your Appliance
Starting a Cooking Session:
- Place the food in the oven and securely close the door.
- Turn the Power Selector dial to choose the desired power level.
- Use the Timer knob to set the appropriate cooking time.
Notes:
- The oven starts cooking as soon as the timer is turned.
- For times under 2 minutes, turn the timer past the 2-minute mark, then return it to the desired time.
- To stop the microwave during cooking, press the door release button.
- Always return the timer to the zero position when removing food before the set time ends or when the microwave is not in use.
Utensils Guide
Use microwave-safe containers made of heat-resistant ceramic, glass, or plastic. Avoid metal containers, as they may cause sparks. Never use plastic film that touches high-fat foods, as it may melt.
Cooking Tips
- Food Arrangement: Place thicker sections of food towards the outer edges of the dish and thinner parts in the centre.
- Standing Time: Allow food to stand for a few minutes after cooking to finish the process and enable even heat distribution.
- Checking Doneness: Ensure steam is rising from all parts of the dish. Poultry joints should move easily, and fish should appear opaque.
Cleaning & Care
Always disconnect the appliance from the power outlet and allow it to cool down completely before cleaning.
- Clean the interior with a damp cloth, using mild detergent if needed.
- Wipe the exterior, avoiding water in ventilation openings.
- Regularly clean the door, seals, and window with a damp cloth.
- Avoid abrasive cleaners and steam cleaners.
- To remove odours, microwave water with lemon juice.
Safety Warnings
- Do not heat liquids or sealed containers, as they may explode.
- Do not use if the door or seals are damaged.
- Only trained individuals should perform repairs involving microwave protection covers.
- Do not place the appliance in a cabinet; it is for free-standing use only.
Disposal
This device is governed by the European Directive 2012/19/EU on waste electrical and electronic equipment (WEEE). Do not dispose of this device as normal domestic waste; use an officially approved waste disposal company.
