Instruction Manual
6.3 Mixing alginate Set the desired mixing time from the scale of 4-28 seconds. Alginates
are usually mixed during 10-12 seconds.
Mixing time, water amount and water temperature have influence on
the segregation time.
Close the lid of the mixing bowl and secure it with a twist.
Make sure it fits and is firmly closed.
Dose the correct amount of water with the measuring cup and fill it into
the mixing bowl.
Mechanic mixing requires some ml less water then manual mixing.
Mechanical mixing considerably shortens processing and segregation
time compared to manual mixing.
Dose the alginate as suggested by the manufacturer and fill it into the
mixing bowl.
Slight fluffing (aeration) of the alginate before use leads to better mix-
ture quality.
Shake the bowl up and down, closing the drill hole with your thumb.
Insert the mixing bowl into the device and close its cover.
Press START. The device automatically stops after the mixing proce-
dure.
Remove the mixing bowl from the device and open the lid with a slight

stances using unclean cloths for drying.
Never use solvent-containing products or cleaning agents (i.e. benze-
ne, alcohol etc.).
Make sure that no fluids enter the inside of the device as this may lead
to irreparable damage.
9.3 Cleaning of accessories Accessories are made of plastic and are easy to clean. Residues of
alginate, polyether and silicon can be removed and cleaned with
a kitchen paper after hardening. Clean scaled accessories with a
soft fabric or cloth, possibly adding warm water and a non-abrasive
household cleaning agent or cleaning solution. Then wipe the acces-
sories with a soft fabric or cloth and clear, lukewarm water. Avoid un-
der any circumstances using unclean cloths for drying.
