Working with the microwave combination oven

Follow the instructions below:

▪ Only those persons who satisfy the requirements stipulated in this installation and operating manual

are permitted to use the microwave combination oven.

▪ Only use the microwave combination oven for the specified use. Never, under any circumstances,

use the microwave combination oven for other purposes.

▪ Take all the safety precautions specified in this installation and operating manual and on the micro-

wave combination oven. In particular, use the prescribed personal protective equipment.

▪ Only stand in the working positions specified.

▪ Do not make any changes to the microwave combination oven, e. g. removing parts or fitting

un-approved parts. In particular, you must not disable any safety devices.

IMPORTANT SAFETY INSTRUCTIONS

When using electrical appliances basic safety precautions should be followed, including the following:

To reduce the risk of burns, electric shock, fire, injury to persons, or exposure to excessive microwave

energy:

▪ Read all instructions before using the appliance.

▪ Read and follow the specific 'PRECAUTIONS TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE

MICROWAVE ENERGY'.

▪ This appliance must be grounded. Connect only to a properly grounded outlet. See 'GROUNDING

INSTRUCTIONS' on page 57.

▪ Install or locate this appliance only in accordance with the provided installation instructions.

Restrictions on use

▪ Use this appliance only for its intended use as described in the manual. Do not use corrosive

chemicals or vapors in this appliance. This type of oven is specifically designed to heat, cook or

toast food. It is not designed for industrial or laboratory use.

▪ Never use the appliance to heat alcohol, e. g. brandy, rum, etc. Food containing alcohol can more

easily catch fire if overheated. Observe caution and do not leave the appliance unattended.

▪ Never attempt to deep fry in the oven.

▪ Some products such as whole eggs and sealed containers – for example, closed glass jars – are

able to explode and should not be heated in this oven.

▪ Do not operate the appliance using microwave only or combination function without food or liquid

inside the cooking chamber as this may result in overheating and may cause damage.

▪ The appliance should not be used to dry linen.

▪ Do not attempt to operate the appliance with: an object caught in the door, door that does not close

properly; a damaged door, hinge, latch, sealing surface or without food in the oven.

▪ Do not use the cavity for storage purposes. Do not leave paper products, cooking utensils or food in

the cavity when not in use.

▪ Do not store any materials, other than manufacturer's recommended accessories, in this oven when

not in use.

Precautions when using the microwave combination oven

▪ When handling hot liquids, foods and containers, care should be taken to avoid scalds and burns.

▪ Liquids, such as water, coffee or tea are able to be overheated beyond the boiling point without

appearing to be boiling. Visible bubbling or boiling when the container is removed from the micro-

wave combination oven is not always present. THIS COULD RESULT IN VERY HOT LIQUIDS

3 For your safety

eikon e2s Service and Repair Manual UL 20

SUDDENLY BOILING OVER WHEN THE CONTAINER IS DISTURBED OR A UTENSIL IS

INSERTED INTO THE LIQUID.

▪ As with any cooking appliance, care should be taken to avoid combustion of the items within the

appliance.

Instructions for safe use of the microwave combination oven

▪ When heating liquids using microwave only or combination function, the contents should be stirred

prior to heating to help prevent eruptive boiling.

▪ Items should be unwrapped when using convection and combination functions.

▪ Excess fat should be removed during ‘roasting’ and before lifting heavy containers from the oven.

▪ Food with a skin, e. g. potatoes, apples, sausages, etc. should be pierced before heating.

▪ In the event of glass breaking or shattering within the oven, ensure that food is totally free of glass

particles. If in doubt, dispose of any food that was in the oven at the time of the breakage.

▪ Switch off the appliance at the end of all the cooking sessions for that day.

To reduce the risk of fire in the oven cavity

▪ Do not overcook food. Carefully attend appliance when paper, plastic, or other combustible materi-

als are placed inside the oven to facilitate cooking.

▪ Remove wire twist-ties from paper or plastic bags before placing a bag in the oven.

▪ Food in combustible plastic or paper containers should be transferred to a microwave/oven proof

container to avoid the possibility of ignition.

▪ Do not use paper products when appliance is operated in the toaster mode.

▪ Oversized foods or oversized metal utensils should not be inserted in a microwave/toaster oven as

they may create a fire or risk of electric shock.

▪ Do not cover racks or any other part of the oven with metal foil. This will cause overheating of the

oven.

▪ If materials inside the oven ignite, keep the oven door closed. Turn the oven off, and disconnect the

supply cord, or shut off power at the fuse or circuit breaker panel.

Requirements to be met by operating personnel

▪ As with any appliance, close supervision is necessary when used by children.

▪ This appliance should be serviced only by qualified service personnel. Contact nearest authorized

service facility for examination, repair, or adjustment.

Requirements relating to the operating condition of the microwave combination oven

▪ As with all electrical appliances, it is recommended to have the electrical connections inspected at

least once a year.

▪ Never remove the external covers of the appliance.

▪ Never remove any fixed internal parts of the appliance.

▪ Never tamper with the control panel, door, seals, or any other part of the appliance.

▪ Do not cover or block any openings on the appliance including air vents/filters and steam outlet.

▪ Never hang dish towels or cloths on any part of the appliance.

▪ Do not operate this appliance if it has a damaged cord or plug, if it is not working properly, or if it has

been damaged or dropped.

▪ The appliance must not be operated without the air filter in place.

▪ If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly

qualified persons in order to avoid a hazard.

▪ Do not immerse the supply cord or plug in water.

▪ Keep the supply cord away from heated surfaces.
