3.2 Operator’s obligations
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 obligations
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 regulations 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 life 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.
•The operator must make sure that all personnel working with the appliance have read and
understood this guide. In addition, the operator must train the personnel and inform them of
the hazards involved at regular intervals.
•The operator must provide the personnel with the necessary protective equipment and
make sure that they wear it.
In addition, the operator must ensure that the appliance is always in a perfect technical condition. For
this reason, the following shall apply:

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’ . Train the operating personnel
for the respective work task; also in accordance with the operating instructions. Check
understanding by means of practical implementation. Repeat the instruction at least once a
year.

3.4 Avoid risks
This chapter describes general, appliance-specific safety instructions. In the following section, additional safety
information relating to a particular operation or situation is placed before the appropriate operation step or
description of the situation.
3.4.1 Risks due to transport of mobile appliance
Numerous hazards such as crushing can arise when transporting this heavy product.
➢acs…varithek®appliances may only be moved manually. Machine-aided transport, e.g. using fork
lift trucks or lift trucks, is not permissible. There is a risk of injury, and the appliance could be
damaged.
➢Remove accessories and transport them separately.
➢Disconnect the connection cable. Unplug the mains plug.

➢Carry out transport with an adequate number of people.
➢Transport only permissible using the castors.
➢Secure the appliance against inadvertently rolling away with the ‘parking brake’.
➢Wear safety shoes to prevent injuries.
CAUTION
►Do not push or pull the appliance over sharp edges. Observe the permissible step
height of maximum 4 mm, otherwise the castors or ‘castors with parking brake’
could be damaged.
►We are not able to rule out the possibility of marks appearing on the floor due to
friction with castors or the formation of scratches due to split cracks in the castors,
for example.

►Lift the appliance using at least 4 people. Another person quickly pulls the pallet
together with the 2 profiles away. Only appropriately trained personnel are
permitted.
➢ATTENTION
Do not unload from the pallet using a fork-lift truck, as this could cause substantial damage.
Lift / deposit a heavy load evenly with your knees bent and your upper body
straight and upright. Your feet should be at least hip-width apart and your
abdominal muscles braced. Breathe out. Do not twist your spine.
Example
➢Ensure that there are no protective foils on the inside or outside of the appliance.
# Clean the appliance
➢Clean the appliance thoroughly before using for the first time.
Clean with a damp cloth and rub dry with a clean cloth.

6 Use
This chapter provides information on the use and operation of the appliance.
6.1 Information on safe use
➢Before each use, check the appliance for any visible damage. The appliance is at room
temperature and is dry. Only use in dry rooms in the building.
➢The socket outlet must be easily accessible so that the unit can be disconnected from the power
supply at any
time.
➢Only operate the appliance with adequate lighting.
Equip the appliance with suitable accessories
➢Do not use gas cooking devices. Do not flambée.
➢For the deep-fryer, use an insertion mask that prevents slipping in the system module. Only
use one deep-fryer on the appliance, as otherwise the extraction and circulating air cleaning
system may be overloaded and odours may develop.
Example
Quickly exchangeable varithek®cooking
modules.
Highly efficient thanks to perfect heat transfer
with thermoplates®.
User tip
Only use correctly sized cooking units.
►Use cooking modules from the Rieber varithek ® range. Roasting, grilling, cooking,
wok cooking and frying. Use
varithek®functional components.
➢Contact Rieber customer service for assistance.
‘Manufacturer’s address’, page 35
➢Only operate appliances with the same voltage, i.e. 2x 400 V or 2x 230 V.

Use

Rieber GmbH & Co. KG
6.2 Ensure undisturbed extraction of steam and vapour
User tip
If the extraction is interrupted, unpleasant odours can develop.
►Make sure that the top edges of the cooking units do not exceed the maximum top
edge in the cooking area.
►With one-sided extraction, type ‘ec’: Place cooking units with higher odour
emissions during cooking and roasting on the right-hand side, as the extraction
effect is more intensive here.
►Ensure that the parts of the upper extraction area are completely assembled.
Ensure that the cutting board (option) is in position.

Allow the ventilation to run on briefly if necessary, so that the vapours rising due to
residual heat cannot spread to the surrounding environment.
➢Press ON/OFF button to switch off.
▌The display goes out. The display is black.
User tip
►We recommend letting the extraction system run on for another 10
minutes at the end of the cooking process, so that the vapour caused by
the residual heat cannot disperse into the environment.
6.3.3 Adjust ventilation intensity
Adjust intensity, levels 1 to 4
➢Press the PLUS button (5), to increase the level.
Press the MINUS button (4), to decrease the level.
