Decide where to install the machine according to the overall arrangement，lighting and avaiability of the clinlc.Put the machine in a clean,dry,draughty and cool place as good working conditions.Make sure that the dental chair chassis contacts the even and solid floor．Under the floor box，there must be inlets/outlets for water，gas and electricity for the
machine within the range of l40X120mm．The water inlet pipe and air intake pipe should be
the 8X5 pipes.The drainpipe should be the hosepipe at中Φ40mm(3／2”)．The port of each pipe is about 40mm away from the the floor．The input wire should be the 3—core 1mm Jacketed cord.about 40mm away from the floor．And connect the protective ground wire well．For the detailed dimensions，please see Fig.2.
Unpack the W／CASE to verify that the whole machine is intact. And check whether the accessories and spare parts are complete and intact according to the packing list．For any questions，please inquire the dealer or our company at once.
Firstly，put the dental chair in the right place．The design of this machine considers the stability of the whole machine,so the foot-fixing screws are unnecessary．But the dental chair chassis must contact the even and solid floorfor fear of accidents
In case of rotation or declining of the whole machine due to the uneven floor，one can fasten the six M12 inner hexad flat end fixing screws into the six M10 screwed boles on the dental chair chassis，and make it fully contact the floor．During the adjustment，Please keep the whole machine even and guarantee as many contact points as possible，so as to ensure the stability of the whole machine.
4. Installing the mouth lamp
Put the wire from the light arm through the lampstand，and then connect the two well．After that．connect the wire connector on the lamp arm to that in the dental cabinet，and put them into the column．Then put the lampstand onto the column，and put the lamp arm in the right place(Note：don’t damage the wire．)
Connect the lamp base wire inserter through the decorative jacket to the lamp arm wire inserter，insert the lamp base handle into the lamp arm hole，and fasten with screws(see Fig.3)，and then cover the screw and seam with the decorative jacket.
Testing and adjustment
Connect water and air pipeline and power supply. The water pressure should be maintained between 0.2~0.4MPa, and an excessively low pressure will not be able to ensure supplying the water required for normal operation, while an excessively high pressure will affect the water-tightness of unit. The regulating range of filter-regulator should be 0.55~0.6Mpa, and if this is not the case, the filter-regulator should be adjusted accordingly to ensure that air pressure is within the correct range. To do so, open the base cover, pull up the rotating handle on the top of filter-regulator for about 10mm(as shown in figure 4), then rotate the handle clockwise for greater pressure and anticlockwise for smaller pressure.
The turbine hand-piece is a precision part. Please read product manual before using the turbine hand-piece
The water used by the hand piece directly comes from the water tank whose output pressure is determined by the pressure of air entering the water tank, while the air pressure is controlled by a dedicated reducing valve provided inside the base of dental unit. To check the pressure, open the base cover and check the pressure meter on the reducing valve, whose value should be 0.2MPa, and if this is not the case, the reducing valve should be adjusted accordingly to achieve this value. The method is same as that for adjusting the filter-regulator.
Pick up the turbine hand-piece from the hanger and step on the pneumatic-control switch(large switch), the hand piece will rotate and cooling water will be ejected, and the hand piece is ready for operation. Attention: at this time, the pressure indicated by the pressure meter on the instrument tray is the working pressure of hand piece (*１), which must not exceed the rated maximum pressure to prevent damage. If the working pressure needs to be adjusted, please use the main control valve provided on the back of instrument tray for the purpose(as shown in figure 5). Turn it clockwise for smaller pressure and anticlockwise for greater pressure, and please adjust carefully by degrees. When the small switch is pressed, the hand piece will not rotate, but only send out air for blowing off chips.
After replacing the bur in high-speed hand piece, try pulling it outwards to make sure that it is properly installed.
2. Saliva aspirator
The unit is equipped with a saliva aspirator which will be ready for working when it is picked up from the hanger. As water is needed for weak suction, water supply must be connected and the minimum working pressure must be ensured. Suction (low) is water suction. Connection through water source is required, and minimum water level is required to be ensured; suction (strong) is air suction. Connection through air source is required, and minimum air level is required to be kept
3. Water storage bottle
The water used by the hand piece directly comes from the water storage bottle, and it is necessary to fill medical distilled water into the bottle in a timely manner. The way of filling water: turn off the air lock on the chassis and wait until the compressed air inside the bottle is discharged, hold the bottle with both hands and rotate it clockwise to remove it, fill water in it and rotate anticlockwise to press it tight against the bottle cap (paying attention to water-tightness), reinstall the bottle, turn on the air lock and the filling process is completed.
The unit’s headrest can be adjusted between two positions including the adult position and children position, and the rotating angle and height of headrest are adjustable for these two positions(as shown in figure 6). To adjust the rotation angle, just hold the headrest, turn handle 1# to the required position and then tighten the handle. To adjust the height, simply pull up or push down the headrest to the required height, and the optimal position can be achieved by combining angle and height adjustment. Attention: it is important to ensure that the headrest is used only after it is securely locked into place after adjustment to prevent accident during use.
Attention: because the backrest of dental chair has a large range of motion, it is necessary to ensure that no object which may come into contact with the backrest exists within the range during operation in order to prevent accident.
Remark: *1. Technically, between the pressure indicated by the pressure meter on instrument tray and the actual working pressure of hand piece, there is a certain difference, which is exactly the pressure loss at the pipeline of hand piece. However, from the user’s perspective, it is important to regard the pressure indicated on the instrument tray as the working pressure of hand piece in order to prolong its service life.
1. Cleaning and lubrication of hand piece
Please consult the instruction manual for the hand piece.
2. Water filter
To ensure normal operation, the water used by the unit should conform to national standard for drinking water, and to achieve this, a water filter is provided at the water inlet of the dental unit’s base(as shown in figure 8) to block foreign matter in the water. Long-term operation will cause dirt to accumulate and obstruct filter element and the passing of water flow, and therefore it is important to clean or replace the filter element to ensure normal operation.
Normally, the filter element must be cleaned or replaced when:
(1) The unit has been used for more than one year;
(2) The pressure loss at filter element is above ０.１ＭＰa;
(3) The filter element is contaminated; or,
⑷. The effluent water becomes turbid;
Steps for cleaning or replacing the filter element: open the base cover, remove the water filter, remove the casing of filter by rotating it anticlockwise, remove the seal ring and filter element, reinstall the water filter after cleaning or replacement while paying attention to water-tightness.
To ensure the cleanness, dryness and stable pressure of air entering the unit, an air filter-regulator is provided at the air inlet of the dental unit’s base(as shown in figure 4) to ensure a stable air pressure which does not exceed the set value and to filter foreign matter and moisture in the air. The filtered moisture will be gathered in a filter cup, which will need to be drained when moisture reaches a certain level in order to ensure filtration effect.
Normally, the filter-regulator should be drained when:
(1) The unit has been used for more than one week;
(2) Water in the filter cup has reached 3/4 of its volume; or,
(3) The color of water in the filter cup has changed (no longer colorless and transparent).
The steps for draining the filter-regulator: open the base cover, rotate a nut at the bottom of filter clockwise to drain water, and then tighten the nut anticlockwise after water is fully drained. To maintain cleanness, a water absorbent such as cotton cloth, tissue or sponge may be padded at the water outlet to absorb water discharged.
4. Hanging valve
When the valve core of hanging valve is inserted into the hanger case, it is fastened by a holding screw. The distance between the valve core and probe is adjustable. Normally, the hand piece or saliva aspirator is put into the hanger, and the probe is pressed in. The valve core is moved leftward, and then a 4X1.2 rubber O-ring is used to seal the air outlet. If air flow could not be cut off after the hand piece is inserted, or air leakage is detected after saliva aspirator and hand piece are put into the hanger case, the holding screw may be loosened and the hanging valve may be moved rightward a bit to see if the valve can be locked to cut off air flow. If this still won’t work, the hanging valve must be disassembled to check if the O-ring has been damaged. A method is provided below for this purpose:
(1) Cut off air supply;
(2) Loosen the holding screw and remove the hanging valve;
Pull out the valve core to reveal the O-ring(as shown in figure 9).
The actuators of patient chair will not work when the hand-piece and suction works and remains the hanging valve empty.
5. Cleaning the unit
The enclosure should be cleaned using a wet cloth and neutral detergent to ensure the smoothness and elasticity of leather finish and avoid corrosion. Parts made of PU and ABS materials should be cleaned using soft cloth and soapy water; while metal coated parts should be cleaned using soft cloth and soapy water, or car wax.
