NOTE

Prior to using a new unit, wipe the surface and the inside with a wet cloth for hygienic reasons. Wash all the removable parts in warm water with detergent.

WARNING!

Open the door slowly and carefully. When opening the door during operation, or after preparation, a large volume of steam is released, and condensed hot water may drip from the lower door edge. There is a risk of scalding.

Microwave oven cooking principles

Place the food evenly. Place thicker areas at the edges.

Watch the cooking time. Cook for the shortest of the prescribed times, and if necessary, for longer.

Overcooked food can ignite.

Cover the food when cooking. Covers prevent spattering and enable more even heating.

Turn around pieces of food such as chicken or hamburger when cooking. Big pieces, such as roast meat, must be turned more than once.

Move meatballs and similar food from the edge towards the centre and vice versa halfway through the cooking time.

Selection of dishes

Ideal dishes for microwave ovens are transparent, for microwaves. They allow the energy to penetrate the cover and food. Microwaves can't penetrate metal, which is why metal or metal-decorated dishes should not be used.

When cooking in a microwave oven, do not use containers/packaging made of recycled paper, as they may contain small metal particles that can cause sparking and subsequent ignition due to microwave radiation.

We recommend circular or oval dishes rather than square or rectangular ones, as the food in the corners tends to be overcooked.

If you are unsure of the suitability of your dishes for heating in a microwave, perform the following test:

1. Fill the microwave-safe container with 1 cup of cold water (250 ml). Put it in the microwave together with the empty dishes in question.

2. Cook at maximum power for 1 minute.

3. When done, touch the dishes carefully. If the empty dishes are warm, do not use them for microwave cooking.

Do not exceed 1 minute of cooking.

CLEANING AND MAINTENANCE

Clean the unit after each use to prevent the accumulation of grease, burned-on remnants of food, and unpleasant smells.

Turn the unit off, unplug the power cord from the wall outlet, and let the unit cool before cleaning and after use.

Do not immerse the power cord, plug, or appliance into water or any other liquid.

Wash the replaceable parts in tepid water with detergent and rinse in clean water.

Clean the inner and outer surfaces and door sealing with a wet cloth. You can use a liquid cleaning agent. Do not use sponges, steel wool, abrasive cleaners or solvents (gasoline, thinners, etc.). You might damage the protective layer.

You can remove odors from the inside by pouring lemon juice and the skin from a lemon into a microwave bowl filled with water, and leaving the bowl for 5 minutes in the oven while operating. Dry the inside with a soft cloth afterwards. If you need to replace the inner light bulb, contact the distributor.

If you do not keep the unit clean, the surfaces can be damaged, which may lead to a shorter service life and dangerous situations.

Installation

1. To install the appliance, select a flat surface that provides enough free space for ventilation openings.

• The minimum height for installation of the appliance is 85 cm.
- The rear of the appliance must be placed against the wall. Leave a minimum distance of 30 ~cm above the top surface of the oven, a minimum distance of 20 ~cm is required between the oven and adjacent walls.

GROUNDING INSTRUCTIONS

This appliance has to be grounded. It is equipped with a supply cable with a grounding conductor and grounding plug. It must be connected to a socket that is correctly installed and grounded. In the case of a short circuit this grounding reduces the risk of electric shock. It is recommended to connect the unit to a separate electric circuit. The use of high voltage is dangerous, and any damage to the oven can cause a fire or other emergency.

WARNING!

Incorrect use of the protective conductor can cause the risk of electric shock.

Note: If you have any questions concerning the grounding or electrical connection, contact a qualified electrician or servicing technician. Neither the manufacturer nor the distributor is responsible for injury or damage caused by incorrect electric connection. The conductors in the supply cable are colored as follows:

Green and yellow - protective/grounding conductor Blue - medium conductor Brown/black - phase conductor

If an extension cord is required, use only a 3-wire extension cord.

The microwave oven is equipped with a short power cord to reduce the risk of tangling or tripping over a longer cord.

• When using a long cord set or extension cord, the following must be observed:
• The ratings of the electrical cords should be at least as large as the electrical ratings of the appliance.
• The extension cord must be a 3-wire cord with a grounding conductor.
• The long power cord should not hang over a worktop or table where children could pull on it or trip over it unintentionally.
