Only use utensils that are suitable for use in microwave combination ovens.
See 'Procedure for preparing the appliance for use'.
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 con-
taining 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. Eggs in their shell and whole hard boiled eggs should not be heated in mi-
crowave ovens since they may explode even after microwave heating has ended.
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.
Liquids and other foods must not be heated in completely sealed containers
as the build-up of steam may cause them to explode.
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.
Precautions when using the microwave combination oven
Microwave heating of beverages can result in delayed eruptive boiling.
Therefore care must be taken when handling the container.
When handling hot liquids, foods and containers, care should be taken to
avoid scalds and burns.
As with any cooking appliance, care should be taken to avoid combustion of
the items within the appliance.
Instructions for safe us e of the mi crow a ve c om bination oven
When heating liquids using microwave only or combination function, the
contents should be stirred prior to heating to help prevent eruptive boiling.
3 For your safety
eikon e2s Service and Repair Manual CE 16
The contents of feeding bottles and baby food jars must be stirred or shaken
and the temperature checked before consumption, in order to avoid burns.
Items should be unwrapped when using convection and combination func-
tions.
Excess fat should be removed during ‘roasting’ and before lifting heavy con-
tainers from the oven.
Food with a skin, e. g. potatoes, apples, sausages, etc. should be pierced
before heating.
When heating food in plastic or paper containers, keep an eye on the oven
due to the possibility of ignition.
Food in combustible plastic or paper containers should be transferred to a
microwave/oven proof container to avoid the possibility of ignition.
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.

3.4 Summar y of hazards

General rules for dealing with hazards and safety precautions

The microwave combination oven is designed to protect the user from all hazards that can reasonably be avoided by design measures.
The actual purpose of the microwave combination oven, however, means that there are still residual risks; you must therefore take precautions to avoid them. A safety device can provide you with a certain degree of protection against some of these hazards. You must ensure, however, that these safety devices are in place and in working order.
The nature of these residual risks and what effect they have are described below.

Hazard points

The following illustration shows a Merrychef e2s microwave combination oven:

Excessive microwave energy

The microwave combination oven generates microwave energy . An operation with an open or damaged door or cavity can result in external and internal burns of body parts following exposure to microwave energy.

Heat generation (1)

The microwave combination oven becomes hot inside the cavity and on the inside of the appliance door. This poses a risk of burns on hot surfaces inside the microwave combination oven, and also on hot appliance parts, food containers and other accessories used for cooking.

Hot steam / vapour (2)

When cooking food the microwave combination oven may generate hot steam and vapour which escapes when the appliance door is opened and which is removed through the air vents on the rear of the microwave combination oven when the appliance door is closed. This poses a risk of scalding from hot steam when the appliance door is opened. Take particular care when opening the appliance door if the top door edge is below your field of vision.

eikon e2s Service and Repair Manual CE 25

Hot liquids

Foodstuffs are cooked in the microwave combination oven. These foodstuffs may also be liquid, or liquefy during cooking. This poses a risk of scalding from hot liquids, which may be spilled if not handled properly.

Live components (3)

The microwave combination oven contains live parts. This means a risk from live parts if the cover is not in place.

Contact with cleaning chemicals

The microwave combination oven must be cleaned using special cleaning chemicals. This poses a risk from cleaning chemicals, some of which can cause skin burns.

Parts moving against each other (4)

For various actions, such as opening/shutting the appliance door or cleaning the appliance door, there is the risk that you will crush or cut your hand.

Undercooking of food products

Ensure all food is hot before serving to protect your guests from microbiological contamination of foodstuffs.
