Assembly Steps
1. Please remove all packaging materials before use
2. The Air Inlet is assembly to the Air Inlet Snap Ring
3. The Exhaust Fan Body is assembly to the Exhaust Snap Ring
4. Connect the USB cable to the USB connector to start using
Instructions for Use
1. Use the USB cable to connect to a power bank or use an USB-AC adapter for power
supply.
(The AC adapter must be powered by an output voltage of 5V and current over 0.3A)
2. Turn on the power on the USB cable and the fan will start moving.
3. It is recommended to pair Sandbox Smart F2 Fan with a coffee bean roaster. When the
coffee bean roaster is on, turn on the fan and adsorb the coffee bean roaster’s
ventilation outlet with the ventilation inlet. The hot air from the coffee bean roaster is
quickly discharged by the fan.
4. When to use the fan bracket: The F2 fan will accelerate the heat discharge of the roaster,
so if the exhaust fan is attached to the roaster and the roasting profile is abnormal, it is
recommended to change the F2 air inlet to be attached to the fan bracket, and At least 2
cm away from the air door of the roaster. (If you use Sandbox Smart R1 roaster with F2,
please be sure to use the fan bracket to avoid affecting the roasting profile of R1)
5. When to use the air inlet cover: When you only need one air inlet to concentrate the
exhaust effect, you can replace one of the air inlets with the air inlet cover (B part).
6. Please turn off power when not in use.
