The Pentamix 3 unit is compatible with all Penta cartridges and Penta mixing
tips. Steel-reinforced Penta cartridges (recognizable by the metal ring) and
red Penta mixing tips are required to exploit the full extent of the performance
capability of the Pentamix 3 unit (e.g., maximum mixing speed). When
cartridges made completely of plastic and materials which do not satisfy
requirements are used, the unit automatically adjusts the mixing speed as
a precaution.
The Pentamix 3 is supplied as a tabletop unit, but can also be mounted on a
wall using the commercially available brackets.
2.1 Comparison with Pentamix 2
• The Pentamix 3 unit can be disconnected from the power supply by using
the main switch on the upper side of the housing (Fig. 7).
• A green LED light on the upper side of the housing shows that the unit is
ready for operation (Fig. 7). The LED light blinks during the self-test when
the unit is turned on and whenever the operating condition does not allow
safe clinical use.
• The Pentamix 3 unit can mix pastes twice as fast as the Pentamix 2.
Pentamix 3 automatically recognizes if the appropriate Penta foil bags with
safety label or metal-reinforced Penta cartridges have been inserted.
Pentamix 3 sets the optimal mixing parameters for the specific material
being used.
• When the "Start" button is released, the Pentamix 3 unit automatically
relieves the tension on the foil bags by withdrawing the plungers, which is
indicated audibly by the sound of the drive motor.
• Safe operation at higher mixing speeds cannot be guaranteed unless
Penta foil bags with safety labels and metal-reinforced Penta cartridges
are used. This is why the Pentamix 3 unit has been designed to adjust
mixing parameters to correspond to the mixing speed of the Pentamix 2
unit when other components are used.
• The locking lever of the inserted Penta 3 cartridge can be opened when
the unit cover is closed so that the mixing tip can be replaced even when
the cover is closed (Fig.14).
• Since the locking lever of the Penta 3 cartridge snaps into a fully open
position, only one hand is required to change the mixing tip (Fig.16).
• Hand wheels and "Start" buttons have been placed on both sides of the
Pentamix 3 unit so that it can be used easily by both right-handed and
left-handed persons.
• The insertion of the cartridge into the Pentamix 3 unit is simplified by the
plungers snapping into place in the uppermost position.

4.1 Tabletop Installation
To connect the power cable, use the hand wheel to retract the mixing shaft.
Close the cover and lay the unit on a suitable pad with the front of the unit
facing down (Fig.1).
Remove the cover on the back of the housing by pressing the two snap
locks (Fig. 2) in the direction of the arrows (Fig. 3).
Thread the power cable through the opening in the cover and plug it into
the power socket on the unit (Fig. 4).
Replace the cover on the back of the unit. Make sure that the noses of
the cover slide firmly into the openings in the housing (Fig. 5) and that the
snap locks audibly click into place (Fig. 6).
Caution: Never operate the unit without replacing the cover;
otherwise, the stability of the unit cannot be assured!
Insert the power cable toward the back in the cable feedthrough.
Insert the power cable of the Pentamix 3 unit into a grounded electrical
socket. If an extension cable is used, make sure that it also provides a
ground wire.
Place the Pentamix 3 unit on a non-slip, level surface and press the main
switch on the upper side of the unit to turn it on (Fig. 7). After blinking
several times, the operating light burns steadily to indicate the unit is ready
for operation.
5. Operation
5.1 Loading the Cartridge
Please carry out the steps in the following sequence exactly.
Have ready one foil bag of base paste and one of catalyst paste as well as
a matching, steel-reinforced 3M ESPE cartridge for a 3M ESPE Penta
impression material. The colors on the foil bag cap and the locking lever or
the product names on the foil bag and the locking lever must be the same.
Insert the foil bags into the unlocked cartridge. The locating lugs make
sure they are correctly seated (Fig. 8).
Press down on the cartridge locking lever until it audibly clicks into place
(Fig. 9).
5.2 Inserting the Cartridge
The Pentamix 3 unit works with both Pentamix 3 cartridges (recognizable by
the locking lever) and the older Pentamix 2 cartridges (recognizable by the
handle on the side).
5.2.1 Inserting the Pentamix 3 Cartridge
Open the unit cover (Fig.10).
Use the hand wheel to retract the plungers until they stop. The plungers
now snap into the uppermost position, and it is not necessary to hold
them in place with the hand wheel.
Hold the cartridge by the handle and insert it into the unit parallel to the
unit opening (Fig.11).
Close the unit cover.
Use the hand wheel to move the plungers forward until the plungers meet
marked resistance from the foil bags (Fig.12). The mixing process cannot
be started until the plungers are touching the foil bags.
Attach a new mixing tip prior to beginning mixing (see Section 5.3).
5.2.2 Inserting and Removing a Pentamix 2 Cartridge
Open the unit cover.
Use the hand wheel to retract the plungers until they stop. The plungers
now snap into the uppermost position.
Insert the cartridge into the unit parallel to the unit opening.
Use the hand wheel to move the plungers forward until the plungers meet
marked resistance from the foil bags. The mixing process cannot be started
until the plungers are touching the foil bags.
Attach a mixing tip prior to begin mixing (see Section 5.3).
To remove the Pentamix 2 cartridge from the unit, use one finger to lift it
by the cartridge handle from below.
5.3 Attaching the Mixing Tip.
Always Attach a Mixing Tip Before Use!
Foil bags equipped with a PentaMatic sealing cap may be used exclusively
with 3M ESPE Penta mixing tips.
