STERILIZING AND DISINFECTING (CON’T)
The autoclaving parameters given reflect the recommendations of our component vendors.
These recommendations are not intended to supersede routine spore testing in accordance with
your state and local health department regulations, where required. It is highly recommended
that a spore test be done in any case to verify your autoclave at the parameters cited.
CAUTION! Scaler handpiece is NOT autoclavable.
Disinfect these items by wiping off any detritus or fluid and then wiping down with an
appropriate topical disinfectant. NEVER soak these items.
PURGING THE WATER SYSYEM
Purging the water system is done each day after the water is turned on and
each time an insert is changed. It is necessary to clear the water system of
air before operating the Scaler because entrapped air can cause the insert
to overheat and to make a high pitched squealing sound. Proceed by
turning on the water, turning on the unit and without the insert in place.
Hold the handpiece vertically with the insert end up and step on the pedal
allowing water to flow. Continue until the water flow is free of bubbles.
Note the mushroom shaped meniscus on the water as it leaves the handpiece.
With the handpiece still vertical and the system free of air, release the foot
pedal and slowly lower the insert into the handpiece. When the insert is
about 3/8”
(10 mm) from being fully inserted, push it the final distance with a twisting
motion. The twisting motion serves to lubricate and seat the “O” ring water
seal. Be sure that the insert is all the way in (fully seated).
When the system is purged and the insert is oscillating, the resulting lavage
flow forms a fine, fan shaped mist pattern as the water stream is dispersed
by the oscillating tip.
NOTE: Lavage flow from the insert depends on the procedure. The range is from 18 cc/minute to
40 cc/minute. Remember that lavage flow is necessary to cool the insert and the tooth.
