USING SAFELY: rules and recommendations
To ensure that the equipment is used safely, the user must abide by the set standards of hygiene and professional
diligence.
The following points should also be kept in mind:
- During use, dust and fragments of material from the patient's mouth or the device being used may be thrust into the
surrounding environment (organic and inorganic particles, metal dust, liquids, potentially infected fluids and biological
materials):
PERSONNEL MUST DULY PROTECT THEIR EYES, BREATHING PASSAGES, MOUTH AND SKIN by wearing
safety glasses, face shields, masks and disposable gloves.
Operate the suction system at high speed in all operations likely to result in a discharge of materials, dust and aerosols
to minimise their dissemination.
N.B.: it is not advisable to use drinking water to supply the dental unit, since it may lead to the formation of a
biofilm in the waterlines and thus facilitate germ proliferation inside the unit itself.
It is recommended to supply the unit exclusively with dedicated liquids (Isotonic Saline Solution or I.P.Purified
Water) using the Separate Supply system.
SERVICING
It is indispensable
to supply the syringe with air and water conveniently filtered. Regular maintenance of the filters in
the unit and draining the condensate from the compressor tank is therefore recommemded.
Grease O-rings (3 - fig. 2) with silicon lubricant S1 once a week. Wearing protective disposable gloves, apply a small
amount of S1 on fingers and lubricate by it.

GENERAL SPECIFICATION
The Threesteril syringe is available just in the three ways (cold) model.
It allows supply of either water, air or spray (i.e. water and air
simultaneously) by pressing control A (water), B (air) or A and B together
(spray effect) fig. 1.
Air supply may be adjusted according to the pressure applied on control B.
The nozzle may be rotated.
Warning!
Before every use, check that the nozzle and the external casing are
correctly fitted onto the syringe body.
Do not use the instrument if it is visibly damaged. Contact an
authorised technical service centre.
CONNECTION TO THE UNIT
The inner body of the Threesteril syringe is already connected to the unit. Fit
the outside body paying attention not to press A and B controls (Fig. 1) amd
rotating slowly into the position that allows a complete fitting until it clicks.
The dental equipment has been setted by Castellini S.p.A. to supply water and
air with correct pressure for the syringe:
air press.:
water press.
Do not exceed in any case these pressure ranges.
