A fixed platform for the combi steamer is a permanently fixed worktable or stand. These platforms are
not intended to be mobile and so are not equipped with features that would help to move them.
Mobile platform
A mobile platform for the combi steamer is, for example, a wheeled worktable or a stand on castors or
stacking kit on castors.

Warning of hazard from hot food, hot food containers and hot liquids
There is a risk of burns from hot food and hot food containers if con‐
tainers tip out of the shelf levels or food spills from containers that are
not held level. This risk is especially high for shelf levels that lie above
the sightline of the user.
Spillage of hot liquid foods can result in scalds if the upper shelf levels
are loaded with liquids or foods that produce liquid during cooking. Do
not use the higher shelf levels that lie above your sightline for liquid
foodstuffs or food that will liquefy during cooking.
Tip-over hazard warning for the combi steamer
There is a risk of the combi steamer toppling over if moved. Always
take great care when moving the combi steamer.
Tip-over hazard warning for the transport trolley
There is a risk of the transport trolley toppling over if moved. Always
take great care when moving the transport trolley. When moving the
transport trolley, watch out for objects in the way or unevenness in the
floor.
Damage or detachment warning for appliance connections
There is a risk of the appliance connections being damaged or de‐
tached if the combi steamer is moved. Always ensure there is enough
length in the supply cables and pipes when moving the combi steam‐
er. After moving, always secure the combi steamer against rolling
away.

3.4 Summary of hazards
General rules for dealing with hazards and safety precautions
The combi steamer is designed to protect the user from all hazards that can reasonably be avoided by
design measures.
The actual purpose of the combi steamer, 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 pro‐
tection 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 size 6.10 gas combi steamer as an example of all table-top units:
Heat generation (1)
The combi steamer becomes hot inside the cooking chamber, on the inside of the appliance door and
on the vents and pipes on the top of the combi steamer. This poses:
■
A fire risk from heat given off by the combi steamer
■
A risk of burns on hot surfaces outside and inside the combi steamer, and also on hot appliance
parts, food containers and other accessories used for cooking
■
A risk of burns on the vents and pipes on the top of the appliance
■
Risk of burns on hot accessories and fittings used during cooking if they have been removed from
the appliance after cooking and set down elsewhere. This applies in particular to mobile shelf
racks (not applicable to ConvoSmoke) or to smoker boxes (only applicable to ConvoSmoke)
Hot steam/vapour (2)
The combi steamer generates hot steam and vapour, which escapes when the appliance door is
opened, and which is removed through the air vent on the top of the combi steamer when the appli‐
ance door is sitting closed. This poses:
■
A risk of scalding from hot steam when the appliance door is opened. You are protected from the
hot steam by the appliance door and its safety catch, provided you use the venting position when
opening the appliance door and generally make sure that the appliance door is intact. Take particu‐
lar care when opening the appliance door if the top door edge is below your field of vision, which is
the case for an appliance in a stacking kit.
■
A risk of scalding from hot steam and hot fat if a water spray is sprayed into hot fat
■
A risk of scalding from the high temperatures of the vents and pipes on the top of the appliance
User manual 25
3 For your safety
Hot liquids
Foodstuffs are cooked in the combi steamer. 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 dealt with properly
Live parts (3)
The combi steamer contains live parts. This poses:
■
A risk from live parts if the cover is not in place
■
A risk of electric shock if the combi steamer is cleaned externally using a hand shower
Fan (4)
The combi steamer contains either one or two fan wheels, depending on the appliance size. This
poses:
■
A risk of hand injuries from the fan wheel in the cooking chamber behind the suction panel if the
suction panel is not fitted in place properly
Contact with cleaning agents
The combi steamer must be cleaned using special cleaning agents. This poses:
■
A risk from cleaning agents, some of which can cause skin burns
Parts moving against each other (5)
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.
Hand shower (6)
There is a hand shower on the combi steamer that can result in various hazards:
■
A risk of scalding if water is sprayed into the hot cooking chamber using the hand shower, e.g. for
cleaning
■
A risk of scalding when the combi steamer is located in the immediate vicinity of equipment for
heating liquid fat, and water is sprayed into this equipment with the hand shower
■
A risk of scalding if a container of hot fat is standing in the cooking chamber into which water is
sprayed with the hand shower
■
A risk of electric shock if the combi steamer is cleaned externally using the hand shower
Break in the cold chain
The cold chain of chilled food may be broken if food is placed in the cooking chamber ahead of time,
e.g. when using a start time preset for the cooking program, or if cooking is interrupted. This poses:
■
A risk to your guests from microbiological contamination of foodstuffs
Gas (7)
This combi steamer is a gas appliance. This poses additional hazards:
■
Explosion hazard if a gas pipe is faulty or leaking
■
A risk of burns from hot exhaust gas at the exhaust outlet
■
A fire risk from hot exhaust gas above the gas appliance
■
A risk of lack of oxygen in the kitchen if a burner is poorly adjusted, there is an insufficient supply
of air for combustion and/or insufficient removal of exhaust gas extraction system.
