alfi Vacuum carafes and vacuum flasks with glass liners - Manual

Congratulations on your purchase of an alfi product. We thank
you for your confidence in our product. This manual contains
some important instructions relating to its use and care. If you
follow these instructions, your alfi vacuum flask will last for
years to come.
alfi vacuum carafes and vacuum flasks
keep drinks at their proper temperature
for hours. The glass liner (1) is made of
double-walled alfiDur toughened glass.
A vacuum is created between the two
glass walls (2) and the capillary (3) seals
the glass liner air-tight. This vacuum
prevents direct heat transfer. The
insulation glass in the vacuum area is
silver coated to improve the vacuum
insulation performance by reflecting radiant heat. Some
models, such as Dan Tea and Cool Bottle, include transparent
glass liners without silver coating. In this case, the fill line and
the colour of the drink can be seen from the outside; the
vacuum insulation performance is slightly lower (see also the
following temperature diagrams). Note: streaks in the glass

Construction of an
alfi vacuum flask
Construction of an
alfi vacuum flask
liner are due to the manufacturing process and do not
influence durability or insulating capability.
Use
Before using the vacuum carafe or vacuum flask for the first
time, check to make sure that the bottom screw is tight. If
necessary, use a coin to tighten the bottom screw by turning it
clockwise. Check the screw from time to time to ensure that
the seal between the glass liner and spout remains tight. Just
before filling the vacuum flask, rinse it with hot water if the
drink is to be kept warm or cold water if the drink is to be kept
cool, in order to improve the insulation performance and
prevent breaking the glass liner. Never use a microwave oven,
conventional oven, stove or hotplate to pre-heat the flask. Fill
the vacuum flask only up to about 2 cm below the spout.
The stopper on alfi vacuum carafes with
hinged lids (Fig. 1) can be opened by
pressing the hinge lever. To fill the
carafe, open the lid all the way.
To pour liquid from vacuum carafes with
one-hand pouring button (Fig. 2), simply
depress the button. To fill the carafe, turn
the lid counter clockwise and pull it up to
remove it. After filling the carafe, depress
button 2 or 3 times to adjust the seal
properly.
To pour liquid from vacuum carafes with
screw top lids (Fig. 3), open the lid ½ a
turn counter clockwise. You do not have
to remove the entire lid in order to pour.
Use warm water and washing-up liquid to clean the inside of
the vacuum flask. The alfi cleaning brush with its soft foam
head simplifies this job. Do not use metal or hard plastic
cleaning brushes. You can remove stubborn stains with alfi
CleanTabs cleaning tablets. After cleaning the flask, carefully
rinse it with water and allow it to dry.
Cleaning and care
Use soft, damp cloth to clean the outside of the vacuum flask,
then dry it with another cloth. Do not use coarse-grained,
abrasive cleaners, scouring pads, sponges or similar items.
Like silver jewellery or cutlery, silver plated vacuum carafes can
tarnish over time. The vacuum flask is delivered in a protective
bag that prevents or delays the surface tarnish. Clean the
silver-plated vacuum flask regularly to ensure a long-lasting,
brilliant shine. For best results, use commercially available
silver polishing cloth or silver care product such as Purargan
from WMF.
Please do not place your alfi vacuum flask in the dishwasher
or immerse it in water if it is not expressly described as
dishwasher safe!

After years of normal use, individual parts such as vacuum
flask stoppers or sealing rings can wear out. The following
spare parts are available for many models: insulating glass
insert, sealing ring, screw lid, stopper and bottom screw. Your
local dealer or alfi customer service can repair your alfi vacuum
flask.

Safety instructions
alfi quality guarantee
- Vacuum carafes and vacuum flasks with glass liners are only
suitable for use where they can be set on a table.
- Do not use the vacuum flask to store or transport ice cubes.
Transporting ice cubes can damage the insulating glass
insert.
- Do not use the vacuum flask to store or transport carbonated
beverages unless such use is expressly designated.
- Do not use the vacuum flask to keep milk products or baby
food warm (risk for bacteria growth).
- Glass insulation inserts are fragile. If a vacuum flask with a
glass insert falls or is not handled properly, the glass insert
can break. Do not drink directly from the vacuum flask
because it could contain glass splinters, especially if the seal
no longer seems tight.
- Do not allow unsupervised children to touch the vacuum
flask.
- alfi vacuum flasks are suitable only for use with food
products.
