2.6 Risks of burns
CAUTION
CAUTION
2.5 Risk of scalding
Caution, risk of scalding!
Heated liquids can cause scalding.
During unloading, hot liquids can leak over the edge of the baking trays.
■Prior to opening the door, always check that there is no water in the baking
chamber.
■If, in case of errors, there is water in the baking chamber, do not take the

Hot steam can cause scalding.
Hot steam can escape at the rear of the device, through the exhaust air vent.
■Set up the device in a manner that no personal injury is caused by the es-
caping steam.
Despite safety technology hot steam and heat escape when the device door is
open.
■Step aside when you open the door.
■Ensure that no other people are in front of the dooropening.
■Open the door carefully.
Hot water can cause scalding. If the solenoid valve is defective or the steaming
valve permanently switched on, hot water can collect in the baking chamber.
■In this case, immediately shut off the on-site water supply.
■Further operation is prohibited.
Caution, risk of burns!
Risk of burning on hot surfaces. The frame, the glass of the machine, and the
surfaces of the baking chamber heat up and become hot.
■Wear heat resistant gloves.
■Open the door carefully.
■Prior to cleaning, let the device cool down.

Page 10
Caution, risk of cutting!
The door of the device is made of glass. There is a risk of cuts from broken
glass.
■When unpacking watch out for any glass damage.
■To avoid cuts, wear suitable gloves.
CAUTION
Caution, respiratory irritation!
During baking in the oven substances can escape, which arise from the manu-
facturing process.
These substances can irritate the respiratory system.
■Ventilate the premises at the initial start-up carefully.
There is a risk of aerosol formation. Do not spray the cleaning agents on hot
surfaces! These aerosols can be inhaled, which can lead to respiratory tract
irritation.
■Wear suitable protective equipment.
■Allow the device to cool down.
■Spray the cleaner onto a suitable cleaning cloth.
CAUTION
CAUTION Caution, risk of crushing!

■Direct the steam upwards.
■Route the exhaust pipe in a manner that steam egress through the air vents
is not possible.
■Keep the necessary distance to safety devices.
3.2 Prevent damage to the device and other objects
3.3 Prevent damage to the device and components
Technical damage!
Escaping humidity can cause a short circuit.
■Attach the water supply lower than the power supply.
■Route the exhaust pipe in a manner that steam egress through the vents is
not possible.
■Collect emerging condensate.
■Drain the compensate away via a suitable medium.
NOTICE
Cold, heat and humidity may damage parts of the device.
■Place the device in a dry, frost-free room.
■Pay attention to the ambient temperatures.
■Ideal temperature range for operation: 50 - 105 °F [10 - 40 °C]

Page 12
Technical damage!
There is a risk of heat accumulation. Components can fail and put the device
out of operation.
■Keep the indicated minimum distance.
■Note the installation plan for the device.
Damage to the device can be caused when the device is placed horizontally.
■Transport the device or device combination always in a vertical position.
■Always move the device combination in conjunction with the transport pallet
and a suitable truck.
■The device combination can be moved, on its own rollers, a maximum
distance of 118 inches [3 meters] for service, maintenance and cleaning
purposes.
NOTICE
Salt residues and aggressive acid residues may damage the surfaces of the
baking chamber.
■Remove salt residues and aggressive acid residues in the baking chamber
daily.
The shop oven is equipped with an LED light strip. This is located between
the two glass panels of the oven door. The LED light strip is fragile and can be
damaged by detergents or mechanical cleaning.
■Do not bring the light strip in contact with detergents.
■Do not bring the light strip in contact with cleaning objects.
■Do not wipe with cleaning cloths over the light strip.
The Dibas 64 blue with optional automatic door is equipped with an automatic
sliding door. When manually pushing there is the risk that components may
be damaged and the automatic door is permanently disabled.
■Always open the automatic door using the “Door” button.
The use of unsuitable cleaning agents leads to damage to the equipment. The
WIESHEU GmbH put a major effort to recommend detergents that on one
hand provide excellent cleaning performance and on the other hand do not
attack and damage the shop oven.
■Use only the cleaning agents indicated.
■Never use abrasive or scouring objects.
Do not lift the Dibas above the baking chamber. These can deform or damage.
■ Move the lifting unit in the specied slots on the rear panel of the device.
The device is equipped with a frequency converter, which can be damaged by
voltage spikes.
■After disconnecting the power plug from the mains wait 1 minute until all
components have completely discharged.
■Then reconnect the mains plug to the mains supply.
