4.5 Caution - electronics
• This equipment contains dangerous voltages. Non-compliance with warnings
from this manual or failure to follow the instructions contained in this manual
can result in loss of life, severe personal injury or serious damage to property.
• There is a risk of serious injury when the safety equipment (emergency stop) is
not functioning or inoperative. There is a danger to life due to unauthorized or
uncontrolled switching on! Unauthorized or uncontrolled switching the roaster
back on can result in serious injury.
• There is a direct danger to life from electric shock when touching live parts. Dam-
age to insulation or individual components can be life-threatening.
• Care must be taken to ensure that all the pipework connected to the coffee
roaster is installed voltage-free, in order to prevent leakage on the machine
which will affect the connections.
• The main input can carry dangerous voltages even if the roaster is inoperative.
• Ensure that appropriate circuit-breakers/fuses with the specified current rating
and type are connected between the power supply and roaster.
• During maintenance on any of the electrical parts, be sure the coffee roaster is
disconnected from the main net: pull the plug.
• Take particular note of the general and regional installation and safety
regulations regarding work on dangerous voltage installations (e.g. EN 50178), as
well as the relevant regulations regarding the correct use of tools and personal
protective gear.
4.6 Caution - gas connection
• Improper connection of gas supply can cause fire and/or explosions. The gas
supply should be installed, adjusted, and tested by a qualified gas installer.
4.7 Caution - heat
• The piping from and to the coffee roaster can reach high temperatures just like
the coffee roaster. It is up to the user to make the provision so that the pipes can
not be touched and/or to apply the clearly visible warning.
• Surfaces of the coffee roaster can become very hot during operation. Contact
with hot surfaces causes severe burns.
4.8 Caution - fire
• The risk of fire arises if the coffee beans are not released in time. Giesen Coffee
Roasters advises not to exceed the bean temperature by 220 °C / 428 °F, and not
to exceed the air temperature by 250 °C / 482 °F.
