IMPORTANT
SAFEGUARDS

When using electrical appliances, basic safety precautions should always be followed,
including the following:
IMPORTANT SAFEGUARDS 2
GENERAL
1. Read all instructions carefully before using the appliance.
2. The roaster is only intended for commercial use.
3. Incorrect operations and improper use can damage the appliance and cause injury to the user.
4. Do not touch hot surfaces. Use handles or knobs.
5. To protect against electrical shock do not immerse cord, plugs, or roaster in water or other
liquids.
6. Always turn o the power button and unplug from outlet when not in use and before cleaning.
Allow to cool before turning o.
7. The use of accessory attachments or software not recommended by the appliance manufacturer
may cause injuries, fire or electric shock.
8. Do not use outdoors.
9. Do not let cord hang over edge of table or counter or touch hot surfaces.
10. Do not place on or near a hot gas or electric burner, or in a heated oven.
11. Always attach plug to appliance first, then plug cord into the wall outlet. To disconnect, turn
any control OFF, then remove plug from wall outlet.
12. Do not use appliance for other than intended use.
13. The roaster operates at high temperatures, and must be kept away from flammable materials,
including chemicals, fabrics, and paper.
14. The roaster must be placed on a heat resistant and slip proof surface that will not allow the
roaster to slide.
15. Allow 20cm of space around the sides and front of the roaster.
16. Never use the ROEST from within a cabinet.
17. Never leave the ROEST unattended during pre-heating and roasting. Also, do not leave the
roaster unattended until 2 minutes after the cooling process has started, to ensure no fire is
present.
18. There is a risk of the coee beans catching fire during roasting. Parts of the roaster also
becomes hot enough to cause burns.

19. The smoke from roasting may be harmful. Please ensure adequate venting of smoke.
20. The instructions for cleaning the appliance must be followed. They are located in
section called Maintenance.
21. The appliance must not be operated by means of an external timer or separate remote-control
system.
22. This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved:
• Children shall not play with the appliance
• Cleaning and user maintenance shall not be made by children unless they are older than 8 and
supervised
• Keep the appliance and its cord out of reach of children less than 8 years
23. If the supply cord is damaged, it must be replaced by a special cord or assembly available
from the manufacturer or its service agent.
24. If coee beans or etc. are sucked in by the ventilation, they will be ejected (shot out) at a
high speed from the exit ventilation hole. Especially this can happen through the cooling tray.
Therefore, the ventilation exit hole must never be directed against people and a person must
never look inside the ventilation exit hole when the roaster is on. We recommend to always use
at least a small ventilation hose to create a 90-degree angle.
25. This appliance is intended to be used in cupping labs, coee shops, roasteries and household and
similar applications such as: sta kitchen areas in shops, oces and other working environments;
- farm house; - bed and breakfast type environments.
26. Save these instructions.

ALTERATIONS SERVICE & ACCESSORIES
1. Do not modify the roaster without permission from the producer.
2. Any accessories not recommended by the manufacturer must not change the operation of the
coee roaster or interfere with normal operation.
3. If disassembling is necessary, allow the machine to completely cool before service is carried
out. Always disconnect the power plug before disassembling the roaster.
4. Do not operate the roaster if not fully assembled.
5. Do not operate the coee roaster if it is damaged or you suspect a malfunction.
6. Do not attempt to service the roaster yourself unless instructed to do so by us. The use of
accessory attachments other than those supplied or recommended by the manufacturer may
cause hazards and can void your warranty.
ELECTRICAL
1. To avoid electric shock, do not operate the roaster in a wet environment or near water. Any
cleaning should be with a moist or dry cloth and should only be performed when the roaster is
cooled down and with the power cord disconnected. Some parts may be removed for additional
cleaning. Please see the cleaning section.

2. The power cord and USB cord must be arranged in such a way that they will not be tripped
over, or able to pull the roaster o the table. Keep the cords away from the front part of the
roaster, which may get very hot and can melt the wire.
3. The roaster needs a dedicated electrical circuit with ground (earth). Do NOT plug other
appliances into this circuit.
4. If an extension cord is needed, please make sure it meets the minimum requirements of power
rating and is fully grounded (earthed). Do not connect other appliances to cord.
MECHANICAL
1. Never touch moving parts, and do not place hands or fingers inside the drum while the roaster
is connected. This includes the trier hole, hopper and the side where beans exit.
2. Never place hands or fingers inside the ventilation exit at the back. The fan has metal impellers
that can create injuries.
3. The coee roaster is heavy, and care should be taken when moving the roaster. Only move the
roaster when it is completely cooled down. Do not lift the coee roaster by the handles, cha
collector or any other detachable parts.
ROASTING
1. When the coee beans ware dropped into the cooling tray, they are extremely hot, and should
not be touched until cooled completely.
2. The operating environment should be clean and free from dust and sand.
3. ROEST is only for roasting coee beans. Roasting other food/items will void the warranty.
4. After roasting has finished the roaster will return to “roasting standby mode” and will be ready
to roast another batch.
5. When roasting is done please leave the roaster to cool down (see page 31).
6. Do NOT disconnect the power until properly cooled down or you can risk damages.
7. The cha collector should be emptied after each roast session or after every 25 roasts.
8. After 1000 and 5000 roasts, the roaster must be cleaned (see page 41)
9. The roaster is designed for profile roasting, minimum 5 minutes roasting cycles. Meaning the
temperature goes down to below 250 degress celcius between each roast. The roaster shall
therefore not be used on maximum power in manual mode. If the environment temperature
reaches 320 degrees Celsius the electrical element will be turned o.
