3General safety instructions
This chapter provides information about residual risks and hazards despite compliance with the intended use of
the device. Generally applicable safety instructions that should generally be complied with are listed here.
Action- and situation-based safety regulations are presented as well and precede the relevant action or
situation.
The information here such as ‘Basic rules of conduct’, 'Operator's obligations' etc refer only to already legally
required compliance requirements such as the workplace regulations according to German law.
3.1 General behaviour
This appliance meets the current state of the art and complies with all acknowledged technical safety-
related regulations. Nevertheless hazards may still arise.
Only use this appliance when it is in fault-free condition and according to the
instructions in this user guide.
During all phases of the appliance's life please ensure that the appliance is safely
integrated into its environment.
Do not make any conversions or modifications to the appliance.
3.2 On use of electrical appliances
Safety instructions according to EN 60745-1:
Work area
Keep your work area clean and tidy. A messy or unlit work area can cause accidents.
Keep children and other persons at a distance when using the product.
Electrical safety
The plug on the unit must fit in the socket. Do not modify the plug in any way. Never use an adapter
in combination with earthed appliances. Using an unmodified plug and a suitable socket will reduce
the risk of an electric shock.
Avoid bodily contact with earthed surfaces such as pipes, heating units, cookers and refrigerators.
The risk of an electric shock is greater when your body is earthed.
Keep the appliance away from rain or damp. Allowing water to get into an electric appliance will
increase the risk of electric shock.
Do not misuse the cable by using it to remove the plug from the socket. Always remove whilst
holding onto the plug. Keep the cable away from heat, oil, sharp edges or the moving parts of other
appliances. Using damaged or tangled cables increases the risk of electric shock.
When working with an appliance outdoors, only use extension cables which are permitted for
outdoor use. Using an extension cable suitable for outdoor use reduces the risk of electric shock.
Potential risk of fire due to heat build-up. Unwind the cable from the spool to prevent any heat build-
up or cable fire. The coupling must have splash protection, must be made of rubber or be rubber-
coated.

Safety guidelines for persons
Be attentive and pay attention to what you are doing, act rationally when working with an electrical
appliance. Do not use the appliance when tired or under the influence of drugs, alcohol or
medication.
Just one moment of inattention whilst using the appliance can result in serious injury.
Make sure the appliance cannot be switched on unintentionally. Double check that the main switch is
in the "OFF" position before inserting the plug in the socket. Connecting the appliance to the power
supply while it is switched on can cause an accident.
Careful handling and use of electrical appliances
Never use an electrical appliance with a faulty switch. An electrical appliance which can no longer be
switched on or off is dangerous and must be repaired.
Keep unused electrical appliances in places where children are not able to reach them. Do not allow
the appliance to be used by persons who are not familiar with it or persons who are not familiar with
this user guide. Electrical appliances are dangerous when in the hands of inexperienced persons.
Handle the appliance carefully. Make sure all moving parts of the appliance work perfectly and are
not jammed, also check whether any parts are broken or damaged to the extent that operation of the
appliance is impaired. Have any damaged parts repaired before using the appliance. Many accidents
are caused by poorly-maintained electrical appliances.
Use electrical appliances, accessories etc. in accordance with these guidelines and in a manner that
is specified for this particular appliance type. When using the appliance, please take into account the
working conditions and the work being carried out. Using electrical appliances for other uses than
that intended can lead to hazardous situations.
Service
Only have the device repaired by qualified and authorised staff. Only use original spare parts. In this
way you can ensure that the appliance remains safe.
3.3 Operator's duties
Operator
The operator is the person who operates the appliance for commercial or economic purposes either
himself/herself or lets others use it and bears the legal appliance responsibility for protection of the
user, staff or any third parties during operation.
Operator's duties
The appliance is used in commercial applications. For this reason, the operator of the appliance must
meet all legal duties relating to work safety.
In addition to the safety instructions in this guide, the safety, accident prevention and environmental
protection regulation applying to the application of the appliance must be complied with.
In particular, the following shall apply:
The operator must be familiar with the applicable work safety regulations and identify, by carrying out
a risk analysis, any additional hazards which are due to the place where the appliance is used.
These hazards must be addressed in the form of operating instructions governing the operation of
the appliance.
During the whole service lift of the appliance, the operator must verify if the operator's operating
instructions reflect the current versions of the applicable regulations. If necessary, the operator must
update the operating instructions accordingly.
The operator must define and assign the responsibilities for installation, operation, repair,
maintenance and cleaning clearly.

General safety instructions

3.4 Personnel qualification
Safe operation requires certain technical skills and personal qualification of each person.
The responsibility for organization lies with the ‘Designated Representative’ (operator).
According to EN 50110-1, the Designated Representative is a 'person assigned the direct
responsibility for the performance of the work. If necessary, this responsibility can be assigned partly
to other persons. [...] The designated representative must instruct all persons involved in the work on
all hazards which may not be obvious for them’.
The work may only be performed by ‘instructed persons’ who have been trained accordingly.
Training, instructions must be repeated, proper understanding must be verified (ideally by way of an
appropriate test).
Only ‘Qualified Staff’ is allowed to carry out repair work.
IEC 60204-1 defines qualified personnel as "persons who, on account of their training and relevant
experience are in the position to recognise risks and avoid potentially dangerous situations."
Electrical work may only be carried out by trained and experienced electricians.
Electro-technically instructed persons may only work under the supervision of a qualified electrician.
Work on the cooling unit should only be carried out by authorised skilled personnel
like a refrigeration specialist.
Repairs and/or overhaul during the warranty period may only be carried out by
the Rieber service department, otherwise any resulting claims may be void.
3.5 Provide protective equipment for personnel
Ensure that the personnel wears the personal protective equipment appropriate to
the relevant situation.

# Hot holding function
The radiant heat on the heating surface produces an air current.
The air evenly distributed by a fan ensures uniform hot holding of the food/meals.
Water in the water tank provides for air humidity / steam. The moist air enrichment
increases the thermal conductivity and prevents the meals from drying out.
