(2) Characteristics of the product

-

The product’s dual direct roast/hot air roasting method uses a combination of

radiation and hot air for superb results and even roasting.

-Designed to maximize heat efficiency for quick roasting up to 15 minutes faster,
preserving the unique flavor and aroma of the beans.

- By controlling the damper you can control the volume of the air exhaust and achieve
your specific roasting profile and aroma.

- Strong blower motor allows for fast cool down (as quick as 2~3 min)

- The safety system terminates the gas supply and shuts off the heater if the preset
MAX temperature is exceeded.

2) A gear safety cover is attached for user safety against the rotation of pulley and
bearings between the drum and control box

-Make sure the gear cover is sealed before you use the product

-Fully cool the machine down before you open the cover to perform maintenance

1) Hazardous voltage
This label is to warn of hazardous voltage.
Turn off the power to avoid any electric
shock or burns before using

2) Moving parts
This label is to warn of its moving part. Use
the safety cover to avoid any injury. Always
turn off the power before doing any
Maintenance

3) Burns
This label is to warn of possible burns. Do
not touch its surface as it’s hot

2) Emergency Stop Switch

-This button is used to prevent exposure to heat and electricity in case of
emergency

- Do not stop the drum or blower when the machine is overheated. Doing so may
cause a fire or breakdown

- The drum will keep working after emergency button is pressed

- Do not stop the drum or blower when they are overheated. The machine’s
special design makes fire or breakdown likely if the drum is completely stopped.

3) Overheating protection device

-Once roasting temperature on the product’s temperature display window reaches
the preset temperature, the heat supply is cut off to avoid overheating

-Do not reset the temperature above the originally pre-programmed temperature.
Otherwise, the machine will overheat.

4) Overflowing voltage protection system

- Power shuts off in the event of electrical malfunctions (short circuit, etc.)

5) Fire extinguishing safety device : Consumer safety device prevents overheating
and automatically shuts off gas when power is off

6) Short circuit protection device : Users should contact their own Gas maintenance
company
