Table 1.3: Safety devices - actions and checks
Hazard points
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.
Live components (3)
The microwave combination oven contains live parts. This means a risk
from live parts if the cover is not in place.
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.

1D. Hazards and safety precautions during installation and setting up
The information in this section should be read and understood by Facility Managers, Equipment Movers and
Service Technicians.
Personal protective equipment requirement
When installing or moving the appliance, ensure the following personal protective equipment is used:
•Protective gloves
•Safety boots
•Hard hat (e.g. when heavy loads are being lifted and working overhead)
To ensure local and national standards and regulations relating to workplaces in catering kitchens and the installation
location are observed, only Service Technicians are permitted to set up the appliance.
Safety precautions relating to the installation location
To prevent hazards that arise from the installation site and environment of the appliances, the following rules must
be observed:
•The floor adjacent to the appliance may be slippery. Clean up spillages immediately.
•The location for installation must comply with operating conditions requirements:
−The ambient temperature lies between +4°C /40°F and +35°C/95°F
−Not a toxic or potentially explosive atmosphere
−Dry kitchen floor to reduce the risk of accidents
•Minimum space requirement must be complied with:
−The minimum height of free space necessary above the top surface of the appliance is 50mm (2”).
−The minimum depth requirement is as follows:
▪Width of appliance = 406.4mm (16”)
▪Total depth with door open = 806.9mm (31.8”)
▪Counter depth = 499.0mm (19.6”)
−Safety clearance on left-/right-hand side / at rear: 0mm
•The appliance must not be installed directly under a fire alarm or sprinkler system. Fire alarm installations
and sprinkler systems must be set up to handle the level of steam and vapour expected to escape from the
appliance when the door is opened.
•There is a risk of fire from the heat emitted from hot surfaces. Therefore, flammable materials, gases or
liquids must not be located near, on or below the appliance.
•It must be possible to set up the microwave combination oven in the installation position so that it cannot tip
over or slide about. The supporting surface must comply with these requirements.
•Vibrations must generally be avoided when using wheeled oven stands or wheeled stacking kits.
•Heat sources in the vicinity must lie at a minimum distance of 500mm (20”).
•The appliance must be installed so that there is absolutely no possibility that liquid from the appliance or
liquid coming from cooking processes can reach deep-fat fryers or appliances that use hot, uncovered fat.
Deep-fat fryers or appliances that use hot, uncovered fat, and which are located in the vicinity must lie at a
minimum distance of 500mm / 20in.

•Requirements for supporting surface is met.
−The supporting surface must be flat and level.
−The supporting surface must have a non-slip surface.
−The supporting surface must be able to bear the in-use weight of the appliance, plus the weight of
the structure supporting the appliance as follows: 50Hz = 46kg /101lbs and 60Hz = 45kg / 99lbs.
Potential risks during installation and setting up
Risk of injury from lifting heavy weights incorrectly
When lifting the appliance, the weight of the appliance may lead to injuries, especially in the torso area. To avoid this:
•Use a fork-lift truck/pallet truck to move the appliance.
•Use suitable lifting gear.
•When lifting the appliance, use enough people for the weight of the appliance (value depending on age and
gender). Observe the local occupational safety regulations for lifting and carrying.
Risk of body parts being crushed when moving and setting the appliance down
To avoid crushing body parts, ensure these instructions are followed:
•Use suitable handling gear
•Move the appliance slowly and carefully, and secure it against tipping over
•Make sure centre of gravity is balanced and avoid jolts
•Ensure the supporting surface meets the requirements specified above
Risk of cuts from sharp edges
To avoid cuts, ensure personal protective equipment is used and exercise caution when handling sheet-metal parts.
Risk of trapping fingers or body in mechanical parts of the appliance
To avoid this risk, when opening or closing the door, ensure that the handle is used and keep clear of the door hinges.
Risk of electric shock from live electrical parts
Live electrical parts are to be found under covers, under the operating panel, along the mains power lead and on
metal parts adjacent to the appliance. As such, work on the electrical system must only be performed by qualified
electricians (as per EN50110-1 in EU or equivalent) from an authorised service company. To avoid risk:
•The appliance must not be installed or operated outdoors.
•The electrical supply must be connected in accordance with applicable local and national regulations and
regulations of the professional associations and of the relevant power supply company.
•Ensure that all electrical connections are in perfect condition and fixed securely.
•Make sure that the appliance is connected to an equipotential bonding system (EU).
•If two microwave combination ovens are installed in a stacking kit, both cases of the appliances and the
stacking kit itself must be grounded in a suitable manner and connected to an equipotential bonding system.
