1. Safety Instructions ATTENTION! Read these instructions carefully before plugging in and operating the unit! As with all units, for safe operation, both the standard safety instructions and the special safety instructions in this operating manual must be carefully followed to ensure correct functioning and safety while operating. 3M ESPE guarantees for trouble-free operation of the Pentamix system only if 3M ESPE system components are used exclusively. 1. The unit must only be used in strict accordance with the following instructions. We have no liability for any damage arising from any other or improper use of this unit. 2. A dangerous condition can result from condensation build-up. Before using the unit, allow the unit to reach room temperature, particularly when moving it from a colder to a warmer environment. 3. The power plug must be connected into a suitably grounded socket. If using an extension cable, make sure that the ground line is not interrupted. 4. Position the device so that the power plug is accessible at all times. 5. The unit must be securely placed either on a flat non-skid surface or mounted to a stable, reenforced wall. 6. Use only Penta™ materials in poly bags in combination with the Penta™ cartridges and Penta™ mixing tips, manufactured by 3M ESPE. 7. Close the cover of the unit before operating. 8. Do not lock the start button. Continuous operation is hazardous. 9. Always turn off the unit and disconnect the plug from the power source before changing the plunger discs. 10. When changing the plunger discs, you must position the smooth side of the new discs to coincide with the poly bag surface (the opposite side of the discs with a fan-shaped design should face toward the plunger rods). Otherwise the poly bag might be damaged. 11. In order to avoid any electrical shock, do not insert any objects into the unit. 12. Use only genuine 3M ESPE parts when replacing defective components as directed in these operating instructions. We have no liability for any damage caused by the use of non-3M ESPE parts or failure to fully comply with these operation instructions. 13. If, for any reason, it is possible that the safety of a unit has been compromised, that unit must be removed from operation and identified in such a way that it is not inadvertently operated again by a third party. For example, do not use unit if it does not work as specified or is visibly damaged. 14. Keep solvents, inflammable liquids and powerful heat sources away from the unit as these may damage the plastic housing. 15. Do not allow cleansers to get into the unit during cleaning; an electrical short or a dangerous malfunction may occur. 16. Only a properly trained, authorized technician should open the unit housing and repair the unit.

2. Description of the Product Pentamix™ 3, manufactured by 3M ESPE, is an automatic mixing unit for processing of Penta™ impression materials. Penta impression materials, manufactured by 3M ESPE, were specifically designed for this device and are supplied in specialized poly bags. Only this form of packaging permits the use in the Pentamix device. Each Penta™ poly bag is sealed with a PentaMatic sealing cap. The external geometry of the sealing cap ensures proper positioning on the cartridge. After the Pentamix device is started up, a special internal device opens the poly bag once sufficient pressure is established by the plunger. The connection pieces located on the PentaMatic sealing caps serve for proper attachment of the mixing tip. The cartridges, labeled like the product, and the PentaMatic sealing caps are the components of a mechanically sound unit for processing of pastes in the Pentamix device that allows a change of products without intermediate cleaning of the device and no loss of paste. 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 utilize the performance capability of the Pentamix 3 unit (e.g., maximum mixing speed) to the full. 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 or issues an error message (see Failures and Error Messages). The Pentamix is supplied as a table-top unit, but can be converted into a wall unit with the commercially available wall mounting brackets.

5.3.2 Attaching the Mixing Tip on a Pentamix 2 Cartridge 8 Open the access door of the unit. 8 Release the locking lever. 8 First place the mixing tips only on the mixing shaft (Fig. j). Turn slightly to align the openings of the mixing tips with the corresponding outflow openings on the cartridges (Fig. k). Attach the mixing tips. Press again to insure that the mixing tips are seated tightly on the outlet openings (Fig. l). 8 Press the locking lever down until it audibly clicks into place. 8 Close the access door of the unit.

5.4 Starting a New Cartridge When starting a new pair of poly bags, first of all the pressure in the cartridge has to build up evenly. Both poly bags open automatically after some 5-15 seconds due to the pressure exerted by the plunger. This event is easy to hear. Catalyst and base paste bags may not open at exactly the same time.

8

Once the bags are open, one paste may flow out before the other paste producing an uneven mixing ratio. For this reason, always make sure to check whether both pastes flow into the mixer and do not apply the paste until the mixture shows a homogeneous color (Fig. n).

Fig. n After mixing the mixing tip remains on the cartridge as a seal!

5.5 Loading the Impression Tray and Penta Elastomer Syringe 8 Press the “start” button. 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 pressed. The brief continued running of the unit which is audible is due to technical reasons and relieves the pressure on the poly bags, keeping the paste extrusion after stoppage to a minimum. Do not arrest the “start” button in order to avoid dangerous situations and continuous working. For safety reasons, use the unit only with closed access door. 8 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. o + p). If necessary, smooth the impression material with a spatula.

8 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 5.3 “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. 8 Put the Penta Elastomer Syringe, manufactured by 3M ESPE, (after removing the plunger) with its rear opening directly onto the mixing tip and press the “start” button (Fig. q).

Fig. q CAUTION: Not all Penta impression materials can be syringed. Please refer to the instructions for use of the respective product.

5.6 Re-starting a Partly Empty Cartridge After prolonged storing (especially silicones) clean the openings of the cartridge caps from possible plugs using an instrument. If necessary, start the unit without the mixer in order to control the flow of the paste. Attach a new mixing tip and start the mixing process. The filling level indicator allows control of the filling quantity. The unit turns off automatically once it is completely empty:

5.7 Exchanging a Cartridge If a cartridge is nearly empty, it is recommended to have a second cartridge at hand, ready for use, to be able to exchange quickly. This cartridge should be prepared as under 5.4 “Starting a New Cartridge”. Utilization capacity time of the mixing tip: refer to 5.5.

5.8 Deposal of Used-up Materials Dispose of used mixing tips and emptied poly bags together with residual garbage.

Remedy Check the power plug at the unit and the outlet to make sure it has been firmly connected. Please contact our Service Center. Use the hand wheel to move the plungers up against the poly bags. Check and adjust seating of the mixing shaft and mixing tips. Insert new poly bags in the cartridge. Certain Penta impression materials require steelreinforced cartridges (e.g., Express™ Penta™ Putty). Replace cartridge. Please contact our Service Center.

7. Maintenance and Care 7.1 Exchanging the plunger discs Always turn off the unit and disconnect the plug from the power source before changing the plunger discs. Only original parts may be used as replacements to insure safe operation. • If damaged, the plunger discs must be replaced. To exchange, unscrew the screw in the centre of the plunger disc. Remove the disc and screw a new one into place (Fig. l). When changing the plunger discs, you must position the smooth side of the new discs to coincide with the poly bag surface. The opposite side of the discs with a fan-shaped design should face toward the plunger rods; otherwise, the poly bags might be damaged.

7.2 Care • Clean all components with a soft cloth and, if necessary, a mild detergent. For disinfection use commonly available disinfection sprays. Under no circumstances use solvents or scouring agents as they will permanently damage the plastic. Do not allow detergent or water to enter the mixing unit. The following agents can be used for disinfection: Pursept-A (Merz) and FD 322 (Dürr). Pursept-A and FD 322 are not available in all countries.

7.3 Maintenance and Repair • No components inside the unit require servicing or repairing by the user. 3M ESPE will only take the responsibility for the safety, reliability and correct functioning of the mixer if: - Any modifications or repairs have only been carried out by personnel authorized to do so by 3M ESPE; - The electrical installation complies with all regulatory requirements; - The mixer is operated according to these instructions; • The plastic cartridges are, dependent on the frequency of being used, wearing parts and thus are not covered by the guarantee for this unit. They should be regularly checked as regards signs of wear and tear (e.g., fissures) and replaced with new ones two years after initial operation at the very latest. The use of worn or defective cartridges can have adverse effects on the mixing proportions, reducing the quality of the impression.
