4.1) Handpieces The unit is supplied with handpiece lubings which accept industry standard handpiece connectors, of various styles. All are tightened to the hose by their respective hose nuts, which use right hand threads. The threads are fine and great care should be taken to ensure that they are not crossed : hold the nut and handpiece square with each other and use as little force as possible when 'starting'the thread. Continue to tighten when there is an easy feel to the mating of threads. Tighten firmly to ensure that the handpiece gasket is compressed sufficiently to prevent air and water leaks. Depending on the ordering specification, one or more of the following fitting styles will be fitted. The illustrations show the hose ends. Align the holes and tubes as indicated : Ensure that the foot control is NOT OPERATED when attaching/detaching instruments, you can engage the locking handle to prevent this.

5) FUNCTTONAL DESCRTPTTON The Trionic 5 is a pilot air controlled dental unit, designed to provide, as appropriate, drive air, spray air and spray water to industry standard, air powered dental instruments, such as high speed turbine handpieces, low speed air motors, air powered 'sonic' scalers and a 3in1 airlwater syringe. Automatic selection control is provided, to ensure that the required services are switched through to the instrument in use. Controls are also provided to allow the adjustment ol air and water flows to suit the instrument fitted and to adjust the degree of spray to that desired. By linklng the air control system to airlelectric conve(ers, the capability of the Trionic 5 is extended to the control of electrically powered instruments, allowing the customer to choose from a range of electric micromotors, piezo-electric ultrasonic scaler and composite curing light, if preferred. There is also an option of a low voltage power source and appropriate instrument hoses, to allow the use of suitable instruments incorporating fibre optic illumination. The air operated foot controls supplied with the unit, disc or lever type, incorporate a variable pressure regulator, the output of which increases with increasing pressure on the disc or lateral movement of the lever. lt is thus possible to control the speed of rolary instruments. A pilot valve in the foot control may be engaged/disengaged by actuation of the spray select switch or button. When engaged, this valve is operated early in the movement of the foot control disc or lever and the signal used to open the spray air and water valves in the unit and thus provide coolant to the handpiece in use. A second pilot valve in the foot control, operated by a switch on the disc type or when the lever movement is to the right of eentre, is used to reverse the direction of electric micromotors, when fitted. A pressurised water bottle system is used to provide spray coolant for the unit, so that it can be installed without dependence on a mains water supply. Such independence is often a mandatory requirement according to the interpretation of bye laws by the local water company. The coolant system incorporates twin bottles and the facility to switch between one bottle and the other at the press of a switch. Power to the electrical circuits of the Trionic 5 is derived from a safety extra low voltage supply (24 volt ac iransformer). The 'basic' circuitry incorporated into the 'motherboard' of each unit acts to 'interface' the membrane switch panel and indicator lamps to other circuit elements. A unit specified with air instrumentation only still utilises the basic circuitry, to power the 3in1 syringe water heater and on/off switch and to control the selection of coolant from bottle A or bottle B, via a solenoid valve. Since the basis of the unit control is by pneumatic means, the removal ol electrical power to the unit will not be catastrophic : operation will 'drop back'to provide normal control of air powered instruments, with coolant available from one of the bottles. However, when the unit is fitted to a ECO 19 chair, i.e. CONTOUR package,it will not continue to operate as the chair is fitted with electrical solenoids that will shut down the air supply.

6) OPERATTNG TNSTRUCTTONS Before operating the unit, ensure that your installer has set the unit with the correct air and water pressures and particularly that an in-line handpiece gauge has been used to adjust the running pressure of air powered instruments, like air motors and turbines, to the manufacturer's recommended values.

6.1)Heighl Adjustment

See figure 2 Standing to the rear of the unit when making adjustments will allow a proper lifting poslure and lifting where indicated will result in the least strain being placed on the unit. When lowering the unit, keep clear of projections or sharps which could cause injury. lncreasing the height of the work surface on a cart is accomplished by simply grasping the rear underside of the unit and lifting upwards. The unit will stay in position when released. It may be necessary to rest the ball of the foot on the rear of the cart base in order to prevent the base from lifting. Protect the surface of the cart base, if applying pressure by foot, to avoid scuffing.

7

Decreasing the height of the unit is accomplished by moving and holding the catch knob upwards, identified in the diagram, then exerting downward pressure on the back of the unit. lf after a long period in one position, the catch knob is difficult to move, lift the unit a little upward and try again. Fleleasing the catch knob will again lock lhe unit in position. Check that the catch knob is properly down when adjustment is finished.

Verlical motion of the unit is controlled by a damping device, to prevent the unit crashing downwatds. Thus there is resistance lo movement which can make it feel stiff. Continued downward pressure, rather than an increase in force, will result in the desired downward movement. DO NOT be tempted to lubricate the damping device inside the unit" This would result in virtuai complete loss of damping.

To alter the height o{ chair attached units, loosen the colunm clamping screw using a hexagon key. Raise or lower the unit to the required height and retighten. DO NOT twisi the unit head whilst doing so as this would alter the rotational stop position. See figures 3 & 4 for cart and module uni1s, figure 5 for chair attached units, lor identification ol shut off valves and switches. First, turn on the air supply, by turning the lever through 90 degrees, in the direction of the arrow. Observe that there are no air or water leaks and then switch on the electricity supply, by moving the green rocker switch/indicator to the I position. The indicator will light. On chair attached versions, switching on the electrics will atomatically turn ON the air and water supply.

6.2) Turning On

With the power now on, observe the states of the control panel indicators. (figure 9)

IMPORTANT

It is essentialto reset the water source selector to position A before proceeding. Switching to A is used to reset an internal circuit. (A false B indication may be given if it occurs when switching on from the mains.) Thereafter, A and B may be selected at will. Change the settings to those desired at the beginning of the work session by operating the appropriate buttons. (see figure 9 for details) When scaler and/or micromotor are fitted, the power and speed limit settings may come on at any position on the .l scale. lt is good practice to reset the scaler and micromotor settings to position , before starling work. When the scaler andlor micromotor are not fitted opfions, the relevant indicator lamps will remain illuminated in the No.8 and No. 4 positions , respectively, to act as power on indicators. B

6.3) Liquid Coolant The unit has been configured to Switch between bottle A and bottle B at will, this provides the user with continuous uninterrupted use as each bottle can be replenished while still using the other. Alternatively, one of the bottles may be filled with a suitable medicant for root work or for flushing the instrument hoses. The reservoir bottles are screwed into special 'caps' housed in the unit head. These caps are fitted with a restrictor valve, so that the bottles may be removed, even when pressurised by the air supply. Escape of air is limited to a small hiss.

To remove a bottle for filling, grasp it around the 'shoulder', which is a stronger part, and unscrew in lhe direction shown by the arrows in the diagrams. Fill to a level below the neck and replace, by screwing up in the opposite direction. DO NOT over tighten. When the bottle is seated, the hiss will be heard to die away, giving assurance of a seal. Note that air pressure building up in the bottle makes it easier to handle, so slowly refitting is an advantage.

HANDPIECE CIBCUIT

Pressing button A on the touch panel will diverl the contents of bottle A (left hand bottle, when viewed from the front of the unit) to the handpiece circuit and light the adjacent indicator. The contents o{ A will then be expressed independently of the contents of bottie B. Pressing button B will likewise divert the contents of bottle B to the handpiece circuit, independently of A and light the adjacent indicator.

Reminder : Button A must be pressed after switching electricity on from the mains. B may subsequently be selected, if desired. Since the bottles work independentty, it is possible to refill the idle one while work continues with the other.

General : D 0 check the bottles regularly for damage and discard suspect ones - they are inexpensive to replace. Use ol bottles with nicks and cuts should parlicularly be avoided.

as plastics can deteriorate through per annum is recommended. least twice at Replacement exposure. and daylight atmospheric D O replace bottles routinely, even when apparently not damaged,

DO NOT allow the bottle in use to run out of coolant. Air can then enter the spray circuits and is a cause of spluttering at shut off (see section 9.3).

DO NOT use aggressive irrigants which may damage the unit or hanpieces.

10

6.4) Operation of lnstruments The unit is specified for the operation of one instrument at a time. When lifting an instrument from its holder, a small air leak is allowed from the instrumen: holder valve (bleed valve). This signal is sensed by the unit which then automatically primes air, water and electrical supplies, as appropriate, for the selected instrument. Operation of the foot control then completes the function of feeding the requisite supplies through the instrument in use.

Foot Control Functions Figure 5 explains the foot control functions. The handle will lock the lever for safety when changing burs or tips. Raising the handle unlocks the lever. Tucking the toe of the shoe under the raised handle allows the control to be lifted and moved, without hands. After placement, push the handle back, to rest on the umbilical where it exits the rear. DO NOT leave the foot control lever in its raised position. lt may be vulnerable to items being lowered onto it. Operate the lever with the side of the foot. Choose wet or dry operation by use of the spray select buttons. Note that for electric micromotors, the direction of lever movement automatically determines forward/reverse of the motor, but that for air instruments the control has no influence on direction. Output from the foot control, and hence the speed of rotary instruments, varies with the degree of movement of the lever. However, lf a piezo ultrasonic scaler is fitted, the control acts as purely on/off and does not affect power. Note that water spray MUST be selected for the ultrasonic to work.

Figure 7

FOOT CONTROL FUNCTIONS

With the handle lowered, the lever will be prevented lrom moving. To raise it, press down on the ear with the side of your sole.

Pressing down fully on this button willturn water spray OFF

Pressing down fully on this buiton will turn water spray ON

Electric motors will run in REVERSE

Electric motors will run FORWARDS

Moving the lever in either direction will stad lhe selected instrument, increasing it's speed the further it is moved

Electric Micromotors A top speed limit may be set (refer to figure 9). This prevents the operator from exceeding a desired speed. The

foot control then gives variation from the staft up speed to the set limit. Note that on limit 1, there is only a small foot control movement between the staft up speed (dictated by the Bien Air controller) and the limit speed. The speed ranges are intended to allow the dental surgeon to subjectively determine a desirable maximum according to the nature of work.

Ultrasonic Scaler The power setting of the scaler may be chosen as one of 8 steps. (See figure 9) Refer to the scaler manufactures booklet for in{ormation on the use of the scaler. Also see the notes under section 9) 'Precautions'

11

6.4) Operation of lnstrumentscont... Spray Controls The amount of water in the spray to individual instruments is adjustable by the spray water control valves (See figure 6). The controls may be operated by hand or alternatively, by the autoclavable key supplied. This is inserled through the small hole in the centre of the control knobs. lndividual spray air control is also provided on each control block. This varies the amount of spray air to each instrument. Note that some high speed turbines require spray air, but others do not, they bleed off some of the drive air. lf your turbine requires spray air, then only water iets would be evident when the spray air control is turned right down. Low speed motors do generally require spray air. Adjust the amount to suit your preference, but see the notes in section 12.7.vi regarding the balance of pressures.

Flush Conlrol

Pressing the flush button with a instrument selected, will allow water to pass through that particular instrument. It is a good idea to use the flush lacility after each use of an instrument, to reduce the risk that contaminants have been drawn back into it. Using the flush button makes a simple contribution to the reduction of cross infection risks.

6.5) Tumbler and Bowl Flush Buttons These are simple membrane switches designed to be used with the Tridac CS'M' spittoon units, when requested with remote tumbler and bowl flush operation. They may be used with other products provided that the switch ratings are rigidly adhered to and that the circuit they are used in complies with the Safety Extra Low Voltage requirements of lnternational Standard BS EN 60601-1 . This will often mean introducing an isolating relay or simiiar between the host product and the Trionic switch circuit. Contact your supplier for advice. Note : liming of the bowl flush and tumbler fill circuils of the Tridac spittoons commences when lhe operating

button is released.

7) PRECAUTTONS 7.1) General Safety Mains voltages are present in control boxes :- DISCONNECT THE ELECTRICAL SUPPLY before service or maintenance. NOTE: The input side of the mains switch remains live, disconnect the supply at the mains isolating swiich serving the installation. EACH NIGHT AND WHENEVER THE EQUIPMENT IS LEF| UNATTENDED FOR LONG PERIODS, USE THE CONTROLS PROVIDED TO SWITCH OFF AIFI, ELECTRICITY AND WATER SUPPL S. Tumbler and spittoon switches on the Trionic membrane switch panel are rated for 24 VOLTS MAXIMUM, 1 WATT MAXIMUM, with a resistive load. DO NOT connect higher rated loads without a suitable isolating inter{ace or relay. lf in doubt, ask your engineer or consult Tridac for advice. lf the tumbler and spittoon switches are used, or if any other connection is made between the unit and an ancillary power supply, it MUST be ensured that the latter conforms to the requirements of international standard EN 60601-1 , for safety extra low voltage. The connection of any ancillary power supply MUST NOT introduce an earth reference to lhe Trionic low voltage circuit. The Trionic circuit MUST REMAIN FLOATING.

7.2) Ultrasonic Scaler

The handpiece lead of a piezo-electric ultrasonic scaler carries high frequency, high voltage power. lt is possible this could interlere with electronic devices brought into close proximity : -

ENSURE THAT THE SCALER IS NOT USED ON PAT!ENTS WITH CARDIAC PACEMAKERS Polarity of the two wires in the handpiece lead lS IMPORTANT. lf the lead is removed and refitted, ENSURE that the wiring is correctly terminated, in accordance with the note on the circuit board. The frictional effect of the high energy, high frequency oscillations of an ultrasonic scaler will give rise to localised heating if conlact is made with other materials (like rubbing two sticks together to start a fire). To avoid injury to the patient, the scaler tip should be kept moving at alltimes. DO NOT ALLOW THE TIP TO DWELL WHILE lN CONTACT WITH ORAL TISSUE. Use copious coolant spray to reduce the risk.

7.3) Water Bottle System The pressurising air to the water bottles comes from the unit's low pressure air regulator. The system is intended to operate at a maximum pressure of 2.7 bar (40psi) :DO NOT INCREASE THE SETTING OF THE LOW PRESSURE REGULATOR ABOVE THIS VALUE. Check the condition of the bottles regularly (see section 6.3). They must be undamaged and must particularly be free of nicks and cuts. Note that they are easy and cheap to replace. Water from the bottles is not filtered. KEEP FOFIEIGN PARTICLES OUT OF THE BOTTLES.

7.4) Electric Micromotors Cooling The motors are cooled by forced air from the drive air circuit of the dental unit, which is adiustable by a restrictor screw in the control block (see section 11.7.i). Air pressure must be sufficient to displace an oil seal fitted to the front shaft of the motor, thus allowing air to pass. There must be sufficient flow to maintain a safe case temperature when the motor is in use. Refer to the instructions supplied with the motor tor the manufacturer's recommendations on cooling. Remove handpieces from the motor when not in use.

7.5) Fibre Optics Check that the voltage rating of the fibre optic bulbs in your handpiece is compatible with the unit ( 3.5 Volts nominal). A small amount of adjustment is possible about the nominal value. Have your technician check the voltage and, if necessary, adjust to suit your handpiece.

8) HYGIENE, DISINFECTION & CLEANING

When cleaning dental equipment, wear suitable protective clothing. This would include a face mask, eye protection and strong rubber gloves, household rather than surgical, as there is a danger that the latter could be easily split or punctured. Where not required for the process, switch off the power prior to cleaning. Keep water/solutions away from electrical devices Use disposable, soft cloths for cleaning. After carring out any of the following, dispose of all used contaminated materials, i.e, cleaning cloihs, barrier film etc as cllnical waste.

Change after each patient' 8.1) Barrier Protection : The surfaces of the Trionic 5 lend themselves to the application of thin film, barrier protection. Transparent films, like cling film, can be readily applied across the front panel, touch panel and tray holder surfaces , without adversely affecting function or visibility of controls. lt is highly recommended that this approach be used to minimise soiling and possible contamination. Additionally, the need to utilise disinfectant cleaners , which may be corrosive and possibly expensive, is very much reduced.

8.2) Surface Cleaning:

After each patient.

Cleaning of the unit's sudaces may be accomplished safely by wiping with a soft cloth, dampened with a mild

delergent solution. Ensure that the cloth is squeezed out. DO NOT soak the unit. Dry the unit after cleaning. Aggressive detergent based products, such as proprietary / domestic floor cleaners may damage the surfaces and must be avoided. Also avoid abrasive cleaners, which will dull, and eventually thin, the surface coating. The approved disinfectant cleaners may be used after cleaning. Use liquid product applied to a cloth - do not use spray application directly on to the unit,

Allow surfaces to dry completely before applying barrier protection. This is particularly important with self adhesive films - low tak adhesive mixed with alcohol, for example, may not remain low tak! Solvents can have a temporary adverse effect on even resistant paint surfaces, but the paint will recover when dried. Sealing the paint under a film before it dries could damage the surface. Recommended Detergent: Near neutral washing-up liquid, diluted. e.9." Fairy liquid"'

8.3) Water Line Flush

After each patient.

Detach the instruments for cleaning and sterilisation, then flush the used instrument hoses into a suitable bowl, by pressing the flush button. This will purge selected hoses with a flow of coolant, minimising any potential for contaminated hose internals. Disinfection: Alpron may be used in the water bottles as a continuos anti-microbial agent.

8.4) lnstrument Trays

After each patient. provided with the unit are suitable for autoclaving at temperatures up to 135C. instrument trays The aluminium Prior cleaning may be accomplished by washing in mild detergent and rinsing clear. DO NOT use hypochlorite solulions or other disinfectants which react on contact with metals. Alter each patient. 8.5) Instrument Hoses The silicone tubing material and metal ferrule nut may be cleaned with a cloth dampened with detergent. Once cleaned they may be wiped with approved disinfectants.

Avoid aerosol cans as the solventslpropellants can swell and degrade silicone materials. Any 'stickiness' of the surface of the silicone, after cleaning, can be overcome by wiping the hoses with a cloth lightly dusted with talc.

8.6) DCI Syringe, Micromotor, Ultrasonic Scaler and any other instruments. All of these should be cleaned and disinfected in accordance with their separate manufacturer's instructions.

9) MAINTENANCE & ADJUSTMENTS Handpieces and attachments should be maintained in accordance with the respective manufacturer's directions. Few pa(s of the Trionic 5 unit require any routine maintenance, outside of that described under Hygiene & Cleaning. However, the items below may require adjustment or periodic attention.

9.1) Pressure Regulators It should be checked that the air pressure regulators are holding their set plessures, which should be at the values listed in the specifications section. A build up of debris can cause the performance to deteriorate. Have your service technician check this annually. lf the regulators are suspect, have them serviced - the service kit contains a new diaphragm and seals to restore original performance.

Access to Pressure Regulators First, switch off electrical power. Catt units house the regulators in the upright column. See figure 12 Chair attached units have the regulators fitted in the base of the chair. To gain access in a cart, lift the unit head to its' full height, remove screw A and pull off cover B. Cabinet mounted units house the regulators in the wall mount services box. see figures 3 & 'l 1. Remove the nut securing the air handle in place. Pull off the handle then turn the cover retaining latch as indicated. Remove the cover. On chair attached units, remove the front cover on the chair base, the regulators are positioned on one side.

9.2) Air Filter Element A clogged filter in the high pressure air filter/regulator (AR.1) can restrict the air supply and reduce the performance of air powered instruments. The condition of the element will depend on the quality of the air supply and it may remain serviceable. However, it is a good idea to replace the filter element when the regulators are checked, as it is an inexpensive part.

9.3) Purging Air from Water Circuit Any air present in the water control circuits of the Trionic unit can cause spluttering or run-on of water when instruments are stopped. Air may be present in the water pipes for several reasons : The unit has just been installed. The water bottles have been allowed to run dry. Air, initially dissolved in the water, has been freed and has accumulated.

To purge air from the system, first ensure that the water bottles are filled. Then starting at one end, select a instrument hose for which a spray control valve exists, remove detachable instruments/motors and hold or hang the hose ends over a basin. Open the spray control valve several turns to allow a copious flow of water. Press the flush valve button on the right of the unit (towards the rear) until a steady flow of water is emitted, then return the hose to it's holder. Repeat the exercise one hose at a time until all hoses have been flushed. ln practice, The unit will automatically clear the system of any air that has entered or built up, so the above procedure should not be necessary. lf the bottle runs dry while in use, simply switch to the other full bottle and continue to run the instrument until a constant supply of water is emitted.
