1.4 Cleaning and disinfection Due to the many kinds of
medicaments and chemicals used in the dental surgery, upholstery or
paintwork surfaces as well as plastic parts may become damaged.
Since damage to surfaces caused by these products depends largely
on the time taken to react, it is imperative that the places
affected be immediately wiped with a damp cloth. The external parts
of the equipment should be cleaned and disinfected by using a
product which has proved to be effective against bacteria, fungi
and viruses (including HBV and HIV). However, as the active
elements in the disinfectants and sterilizing products have
aggressive effects, we recommend using products which contain no
more than the amounts shown below of the following products:
Ethanol 96% = max. 40g per 100g disinfectant Propanol = max. 35g
per 100g disinfectant 1.4.1 Cleaning and disinfection
instructions
WARNING! Always switch off the dental unit before performing any
cleaning or disinfecting procedure on the external parts.
WARNING! Make sure during cleaning that fluids do not penetrate
into the equipment since they may cause malfunction.
WARNING! In general, use only disinfectants which are approved
for use on painted surfaces and plastic surfaces in dental
medicine. Procedure Cleaning and disinfection are two closely
related operations and should be performed together. z Cleaning:
take a new piece of disposable paper or sterile gauze dampened with
the
chosen cleanser and wipe the dirty parts z Disinfection: dampen
clean paper or gauze with the chosen disinfectants such as
alcoholic disinfectants over the parts to be disinfected again.
Leave to work for about 10 minutes and then remove the residue with
dry disposable paper or sterile gauze.
If the parts are extremely dirty or contaminated, conduct a
pre-disinfection before the procedure of cleaning. That is, using
the paper or gauze with plenty of cleanser, generously apply the
disinfectant to the contaminated parts in order to cover them
thoroughly. Wait for the time recommended by the manufacturer to
allow the disinfectant to eliminate the bacteria and remove the
organic deposits.

instructions supplied with each
Handpieces Cleaning and disinfection z Operate as the
instruction of the motor provided with the motor stated. Syringe

spray nozzles of all the instruments on the dentists board and the
syringe on the assistants board. The disinfectant should be left to
work for a certain amount of time inside the lines in order to
disinfect them. To perform the disinfecting operation, proceed as
follows:
1. Keep the water bottle empty and switch the air pressure lever
to Pressure Increase to draw away the filth and dry the tubes.
2. Switch the air pressure lever to Pressure Relief. Remove the
white distilled water bottle by turning it in a clockwise direction
and install the pink bottle containing disinfectant.
3. Make sure the water regulators for the spray nozzles, which
are located at the bottom of the board, are open (otherwise no
water- or not enough water- will come out).
4. Take out the syringe and drain the water line. When air comes
out of the line, it means it has been fully drained.
5. Repeat the same procedure for the syringe on the assistants
board and for the rest of the dynamic instruments.
6. Switch the air pressure lever to Pressure Increase. 7.
Operate the dental instruments until disinfectant has been sprayed
out for seconds one
by one.
8. Keep the unit off for one or two hours.
9. Switch the air pressure lever to Pressure Relief, remove the
pink disinfectant bottle and reinstall the white distilled water
bottle.
10. Take out the syringe and drain the water line. When air
starts to come out of the line it means that it has been fully
drained.
11. Repeat these operations to drain the disinfectants out of
the lines leading the instruments. 12. Switch the air pressure
lever to Pressure Increase. 13. Operate the instruments and wait
until the distilled water starts to come out.
NOTE! Allow the distilled water to come out for at least 6-7
seconds.

9. Maintenance
NOTE! Proper maintenance can extend the cycle life of the unit!
In order to keep the dental unit in proper working order it is
essential to perform the routine maintenance operations as
indicated in the following. z Maintenance of the instruments
Maintenance instructions are supplied for each instrument.
WARNING! We advise performing the maintenance operations for the
instruments with the equipment turned off. z Check the voltage for
the power supply at intervals. The air pressure and water pressure
must
conform to the requirements of this unit. And the pipes must be
smooth. z Check the sensitivity for the movement of the dental unit
parts and the control buttons. z At the end of each work day, use
liquid germicide to clean ceramic bowl and spout. And clean
bowl filter under running water and with detergents available on
the market.
WARNING! Never use acids or abrasive products.
WARNING! Always wear gloves to perform this operation. z At the
end of each work day, clean the suction filter. Pull out the
suction filter and drop the dirty.
Reinstall it after the cleaning and make sure the installment
will not cause air leaks.
WARNING! Always wear gloves to perform this operation. z
Cleaning the air return line. Every month, check the filter of the
oil collector. If necessary,
replace the filter element. z Air filter: In order to guarantee
the proper operation of the unit, an air filter is designed to
locate
at the air inlet so as to prevent the impurity in air. The
filter collector must be cleaned or replaced timely to avoid
abnormal function of the unit. Generally, the filter should be
replaced every one month.
z Water filter: In order to guarantee the proper operation of
the unit, a water filter is designed to locate at the water inlet
so as to prevent the impurity in water. After a long time
operation, the dirty may jam the filter collector and the water
flow may be obstructed. Therefore, the filter collector must be
cleaned or replaced timely. Generally speaking, it should be done
every one month. And if any one of the following case happened, the
filter also should be cleaned or replace.
1. The filter collector has been used for more than 1 month; 2.
The filter collector is polluted; 3. The water coming out becomes
turbid.

The way to replace the filter collector: open the hydro-group
and disassemble the water filter. Then remove the shell of the
filter by turning it anti-clockwise. Take out the seal ring and
collector in turn. After cleaning or replacing, put them in the
original place. Please take care of the seal to avoid leaks.
z Working instruments For the maintenance operations, refer to
the manual supplied with each instrument.
10. Troubleshooting
NOTE! This part of instructions is intended to be an aid to
self-help. If faults cannot be localized with the aid of this
troubleshooting scheme, an engineer specially trained or authorized
