8. Maintenance
8.1
Daily maintenance
Operational safety and utilizability of the device are directly connected
to the recommended care and maintenance measures. Regular main-
tenance and care are therefore indispensable. If there are any indica-
tions that a risk for the patient or operator could arise from abrasion
of components or from a technical error, the device is to be inspected
immediately by an authorized customer service or Mikrona’s customer
service and/or the fault is to be cleared.
Check the function of the magnetic main water valve every day. If
the magnetic valve for main water supply is working, only little water
should run from the multifunction syringe when pressing the specific
button after switching off the main switch (7.1 Main switch).
Take care that no water enters the device when cleaning as this may
cause errors.
Clean and disinfect the surface of the device regularly, e.g. with Dürr
Surface Disinfection FD 322 / FD 350.
8.1.2 Daily maintenance of the spittoon
The spittoon is tightly connected to the unit by adapter.
Clean and disinfect the surface of the spittoon regularly, e.g. with Dürr
Surface Disinfection FD 322 / FD 350.
It is recommended to regularly rinse the spittoon with tap water
throughout the day, for example to aspirate a glass of water through
the drain and the spittoon after each patient
It is recommended to disinfect and clean the spittoon at least once a
day with Orotol ultra. Application once a day: In the evening after the
last patient. Application twice a day: Before the lunch break and in the
evening.
After carrying out the disinfection, it is very important to observe the
residence time (DGHM: 1 h) before continuing to work on the corre-
sponding unit. The same applies to flushing.
In order to create an efficient solution with Orotol ultra (10g/liter) dis-
solve it entirely in lukewarm water right before use. It is not possible
to keep the solution in stock as it is only durable for a short period of
time.
Never clean the spittoon incl. the rinsing basin with a household clea-
ner. Due to potentially appearing foaming, neutralizing tensides and
insoluble abrasives the aspiration system may become disabled. For
in-between-cleanings of the drain, spittoon and rinsing basin use Oro-
tol MD 550 or Orotol MD 555.
Avoid under any circumstances to uncontrollably mix any products –
incl. disinfectants – by means of the spittoon (This may result in dama-
ge of the aspiration system).
8.1.1 Hygiene recommendations for
water-bearing systems
Before starting a new day of treatment, rinse all extraction points, such
as glass filler, turbine, micromotor, tartar remover and multi-function
syringe (without instruments attached) for two minutes with water.
This
significantly helps to reduce micro-bacterial accumulations caused by
stagnation.
It is further recommended to rinse used extraction points for 20 se-
conds with water after each patient and at the end of the day.
8.1.3 Cleaning and Disinfecting the spittoon valve unit
Press button for spittoon rinse.
Pour an amount of disinfectant into the spittoon, e.g. Orotol Plus.
Keep pressing button for spittoon valve until the disinfecting agent has
been completely sucked up.
Do not use foaming or aggressive cleaning agents.
