4. Installation

! ! Prior to installing the unit, make sure the power supply
corresponds to the supply quoted on the rating plate of
the unit.
! ! In order to work with the unit, the power plug must be connected
into a suitably grounded socket. In case of using an extension cable,
make sure that the ground line is not interrupted.
Pentamix Lite can be placed on any non-skid flat surface.The unit is
ready for operation as soon as the power cable has been plugged into
an electrical outlet and the power switch has been turned on.
The Pentamix Lite mixing unit can be permanently left in operational
mode. Power consumption in the standby mode is extremely low
(<1 W).

5. Operation

5.1 Swiveling the Unit into Working Position
! !
Safe and correct operation of the Pentamix Lite is assured only when
it is in working position. When swiveling the unit, use caution to avoid
the possibility of injury from jamming or crushing your fingers.
With one hand, slowly tip the mixing apparatus of the Pentamix Lite
mixing unit forward from the horizontal park position until it audibly
snaps into the working position (Fig.1).
Do not push the unit beyond the final position as this could lead to
technical problems.
5.2 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 3M ESPE Penta cartridge for Pentamix Lite.
Insert the foil bags into the unlocked cartridge (Fig. 2).
6
The locating lugs make sure they are correctly seated.
Press down on the cartridge locking lever (Fig. 3) until it audibly clicks
into place.
5.3 Inserting the Cartridge
Take the cartridge in your left hand.
Turn the plunger adjustment knob clockwise with your right hand until
it stops and hold it in place. The plungers are now in the uppermost
position.
Place the cartridge into the unit.
Rotate the plunger adjustment knob anticlockwise until the plungers
markedly touch the foil bags (Fig. 5).
! ! The unit cannot be activated
until the plungers touch the
foil bags.
Attach a mixing tip prior to begin mixing (see Section 5.4).
5.4 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.
Release the lock (Fig. 6).
First, place the mixing tip only on the tip of the mixing shaft (Fig. 7).
Turn slightly to align the mixing tip with the corresponding outflow
openings of the foil bags (Fig. 8). Attach the mixing tip and press down
firmly to insure that the mixing tip is seated tightly on the outflow
openings (Fig. 9).
Press the locking lever down until it audibly clicks into place (Fig.10).
5.5 Starting a New Cartridge
Press the green "Start" button on the cartridge (Fig.11).
When a new pair of foil bags is started, you must wait 15-25 sec.
until pressure has built up in the cartridge; the foil bags will then
open automatically.
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.12).
After mixing, leave the mixing tip on the cartridge as a seal!
5.6 Loading the Impression Tray and Penta Elastomer
Syringe
Press the green "Start" button on the cartridge.
Please note: A few seconds pass before the paste becomes visible in
the mixing tip.
The unit only functions as long as the "Start" button is held down.
As soon as the button is released, the paste does not flow any more.
When the "Start" button is released, the Pentamix Lite unit automatically
relieves the tension on the foil bags by withdrawing the plungers, which
is indicated audibly by the sound of the drive motor.
Tilt the tray to load it. Fill the tray bottom continually from one end
to the other, keeping the opening of the mixing tip immersed in the
impression material (Fig.13). If necessary, smooth the impression
material with a spatula.
A mixing tip may only be used as long as the mixing shaft inside the
mixer rotates smoothly. If the mixing procedure is interrupted for more
than 30 sec, the material inside the mixing tip begins to harden and a
new mixing tip must be assembled (refer to 5.4 "Attaching the Mixing
Tip"). If the mixer is operated while containing hardened material, the
catalyst nipple of the sealing cap can be damaged or may break away.
