Preparation - Buffalo DM868 Mode D'emploi

UK
Maintenance
• Ensure to locate the unit vertically after cleaning.
• During cleaning, do not damage the interior components. Should any damage occur, call BUFFALO
agent or qualified technician. Do not attempt any unauthorized repairs to avoid accidents.
• Always use fresh water. If the water is reused many times, mineral substances may adhere to the
surface of the components, thus influence the appliance's performance.
• For use, do not place hot appliance in cool water or vice versa. Let it cool down to room temperature
then lower into cool water for use. Otherwise the function and lifetime will be affected.
De-scaling
Why... Normally tap-water contains minerals. When water is heated to a certain temperature,
there will be scales accumulated on the heater or surface of the appliance, which will
affect its performance and contaminate the outlook as well.
We suggest cleaning the machine after every 20 times of use, or when accumulated
working time amounts to 100 hours or less. Or you can clean your appliance at
different intervals as water quality varies in different places.
When... After every 100 hours of use, the displays shows "CLEAN". Meanwhile, the unit beeps
every time it is switched on to remind cleaning is needed.

Preparation

A container over 18cm high, food grade vinegar (e.g. white vinegar)
How... 1. Put the unit into the container. Then fill the container with water and appropriate
amount of vinegar (ratio: 5g vinegar to 10L water) up to the Max marking on
the unit. CAUTION: Should any vinegar splash onto your eyes, rinse
immediately with fresh water and turn to a doctor if needed!
2. Plug in the unit. Press and hold
cleaning mode (working under 80°C for 3 hours).
3. Press
power automatically.
4. Dispose of the solution of water and vinegar properly. Do not use the same solution
for a second time. If the results are not satisfactory, repeat the above operations.
5. Clean the unit and container with fresh water thoroughly, then dry and store in a
well-ventilated place.
