ENGLISH
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.
왘
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.
왘
Put the Penta Elastomer Syringe (after removing the plunger) with its
rear opening directly onto the mixing tip and press the “Start” button
(Fig. 14).
!! CAUTION: Not all Penta impression materials can
be syringed. Please refer to the instructions for use
of the respective product.
왘
Cleaning the Penta Elastomer Syringe
Please refer to the pertinent Instructions for Use for information about
cleaning and disinfecting the Penta Elastomer Syringe.
5.7 Removing the Cartridge
!! Do not press the “Start”
button while removing
the cartridge!
왘
Turn the plunger adjustment knob anticlockwise with your right hand
until it stops and hold it in place. The plungers are now in the upper-
most position.
왘
Using your left hand, remove the cartridge from the device (Fig. 15).
5.8 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 mixer and start the mixing procedure.
5.9 Replacing a Cartridge
If a cartridge is nearly empty, we recommend that you have a second
cartridge ready for use at hand so that you will be able to replace
the exhausted cartridge quickly. This cartridge should be prepared as
described under 5.5 “Starting a New Cartridge”.
Do not forget to move the plungers into contact with the bags!
Lifetime of the mixing tip: see 5.6.
5.10 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 mixer.
왘
Store any cartridges with partially used foil bags either horizontally
or with the mixers pointing down (Fig. 16). If stored improperly, the
impression material may flow backwards, which would prolong the
restarting time or cause the base and catalyst pastes to mix.
왘
When there is a partially used cartridge in the unit and it is in park
position, the plunger discs hold the foil bags in the cartridge. It is not
necessary to remove the cartridge before parking the unit.
5.11 Fill Level Gauge
The fill level gauge shows how much material remains in the foil bags
(Fig. 17).
When the foil bags are completely empty, the red fill gauge marker
disappears, and the unit shuts off automatically.
5.12 Parking the Unit
The Pentamix Lite unit can easily be folded into a compact park position
when its operation is temporarily not required.
!! When swiveling the unit, use caution to
avoid the possibility of injury from jamming
or crushing your fingers.
왘
Before tipping the mixing apparatus of the unit containing a cartridge,
always be sure that the plunger discs are in the cartridge and that
the mixing tip which has been used is still in place. The cartridge may
otherwise fall out of the unit and be damaged.
왘
With one hand, slowly tip the mixing apparatus of the Pentamix Lite
mixing unit backward from the working position until it audibly snaps
into the park position (Fig. 18).
왘
Do not push the unit beyond the final position as this could lead to
technical problems.
5.13 Transporting the Unit
When in the park position, the Pentamix Lite unit can be easily transported
and stored.
!! When transporting the unit, use caution
to avoid the possibility of injury from jamming
or crushing your fingers.
왘
Move the unit into the park position before transport; see 5.12.
왘
Turn off the power switch on the Pentamix Lite unit and remove the
power cable from the unit.
왘
Grasp the unit from the side with one hand (Fig. 20) and carry it using
the carrying handle in the housing (Fig.19).
5.14 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.
The used-off-packaging of the Penta base paste is subject to the EU
Waste Electrical and Electronic Equipment Directive (WEEE) and must be
collected and disposed in the EU separately from other waste in accor-
dance with the local regulations for electric or electronic waste.
5.15 Return of Old Electric and Electronic Equipment
for Disposal
1. Collection
Users of electric and electronic equipment are required to collect their
old equipment separately from other waste in accordance with the
regulations of the specific country. Old electric and electronic equipment
must not be disposed of with unsorted household waste. This separate
collection is a prerequisite for recycling and reprocessing as an important
method for preserving environmental resources.
2. Return and Collection Systems
When your Pentamix Lite is no longer usable, do not dispose of the device
with household waste. 3M Deutschland GmbH has set up special disposal
facilities to handle the equipment. Details about the procedure for the
specific country can be obtained from the pertinent 3M subsidiary.
5.16 Notes
Before using the foil bag, record the batch data printed on the bag (batch
code, use-by date, 14-digit GTIN) for the office’s own documentation or
for questions to the manufacturer and archive the data so that they can
later be accessed at any time.
Penta Mixing Tips - Red are single-use devices and would be damaged
when removing set impression material.
Please keep the single-use accessory in the original bag to guarantee
the traceability of the batch.
