5.3.1 Attaching the Mixing Tip to a Pentamix 3 Cartridge

왘

Release the locking lever by pushing up the lock (Fig.13) and push the
lever all the way up until it snaps into place (Fig.14).

왘

First place the mixing tip with the CE symbol pointing upwards only
on the tip of the mixing shaft (Fig.15). Turn slightly to align the mixing tip
with the corresponding outflow openings of the foil bags (Fig.16).
Attach the mixing tip and press down firmly to insure that the mixing tip
is seated tightly on the outflow openings (Fig.17).

- Caution: Never attach the mixing tip only to the outflow openings of

the foil bags when the mixing shaft has been withdrawn. This could
prevent the full insertion of the mixing shaft into the mixing tip.
In this case, the operating light will blink and the unit will not start
(see Section 6).

왘

Press the locking lever down until it audibly snaps into place (Fig.18).

5.3.2 Attaching the Mixing Tip to a Pentamix 2 Cartridge

왘

Open the unit cover.

왘

Release the lock.

왘

First place the mixing tip with the CE symbol pointing upwards only on
the tip of the mixing shaft (Fig.15). Turn slightly to align the mixing tip
with the corresponding outflow openings of the foil bags (Fig.16).
Attach the mixing tip and press down firmly to insure that the mixing tip
is seated tightly on the outflow openings (Fig.17).

왘

Press the locking lever down until it audibly clicks into place (Fig.18).

왘

Close the unit cover.

5.4 Starting a New Cartridge

왘

Press the “Start” button (Fig.19). The Pentamix 3 unit can be operated
using either the left-hand or right-hand “Start” button.

왘

When a new pair of foil bags is started, please wait

5-15 sec.

until

pressure has built up in the cartridge; the foil bags will then open
automatically.

왘

Once the bags are open, one of the two pastes, which are of different
colors, may flow out first, producing an uneven mixture. For this reason,

observe the flow of the two pastes, discard any uneven mixture,
and do not apply the paste until the mixture shows a homogeneous
color

(Fig.19).

왘

After mixing, leave the mixing tip on the cartridge as a seal!

5.5 Loading the Impression Tray and Penta Elastomer Syringe

왘

Press the “Start” button. The Pentamix 3 unit can be operated using
either the left-hand or right-hand “Start” button.

- The unit extrudes paste only as long as the “Start” button is held

down. When the “Start” button is released, the motor audibly
continues to run briefly. This movement relieves the pressure on the
foil bags to minimize the unnecessary flow of the pastes.

- Do not lock the “Start” button as this can lead to hazardous situations

and undesired continuous operation. For safety reasons, use the unit
only when the cover is closed.

왘

Tilt the tray to load it. Fill the tray continually from one side to the other,
keeping the opening of the mixing tip immersed in the paste (Fig. 20
or 21). If necessary, use a spatula to smooth the impression material
surface.

왘

When filling a Triple Tray

, fill one side first. Release the “Start” button

briefly and turn the tray over, then fill the other side.

왘

A mixing tip may be used only as long as the mixing shaft inside the
mixer rotates smoothly. If the mixing process is interrupted for more than
30 seconds, the material inside the mixing tip will begin to set, and a
new mixing tip must be attached (see Point 5.3, “Attaching the Mixing
Tip”). If the mixing unit is operated when there is set material inside it,
the unit will turn off automatically to prevent damage.

왘

Attach the rear opening of the Penta Elastomer Syringe (after removing
the plunger) to the mixing tip opening and press the “Start” button
(Fig. 23).

- CAUTION: Not all Penta impression materials can be syringed.

Please refer to the Instructions for Use of the specific product.

5.6 Re-starting a Partly Empty Cartridge

왘

After prolonged storage (especially for silicones), use an instrument to
remove any plugs that may have formed from the outflow openings of the
foil bags.

왘

It may be necessary to start the unit without a mixer to check the paste
flow.

왘

Attach a new mixing tip and start the mixing procedure.

5.7 Replacing a Cartridge

If a cartridge is nearly empty, we recommend to have a second cartridge
ready for use at hand so that it is possible to replace the exhausted
cartridge quickly. This cartridge should be prepared as described under
5.4 “Starting a New Cartridge”.

Experienced personnel can even replace a cartridge while filling a tray. You
can save time by attaching the full mixing tip from the empty cartridge to
the prepared new cartridge. Do not forget to move the plungers into contact
with the bags!

Lifetime of the mixing tip: see 5.5.

5.8 Storage of Partially Used Cartridges

왘

Foil bags which have been started and partially emptied must be stored
only in the cartridge and with attached and filled mixing tip.

왘

Store any cartridges with partially used foil bags either horizontally
or with the mixing tip point down (Fig. 24). If stored improperly, the
impression material may flow backwards, which would prolong the
restarting time or cause the base and catalyst pastes to mix.

5.9 Fill Level Gauge

The fill level gauge shows how much material remains in the foil bags.

If the plungers have snapped into the uppermost position, the red fill level
marker is not visible.

When the red marker reaches the first line, there is still enough impression
material in the unit to fill completely either a large impression tray or three
Triple Trays (Fig. 25).

When the foil bags are completely empty, the red fill gauge marker
disappears, and the unit shuts off automatically.

5.10 Disposal of Consumable Materials

Dispose of used mixing tips and empty foil bags in residual waste. Be sure
to comply with local waste disposal regulations.
