1 Important information

1 Important information

General

This technician's manual contains all details for the maintenance and repair of your STATMATIC
device. The instructions for operation, maintenance and changing of spare parts must be complied
with so that the device can operate correctly. The content of this Technician's Manual may be
modified without notice in order to reflect modifications and improvements to the STATMATIC.
This Technician's Manual must be used in conjunction with the Operating Instructions.
The STATMATIC has been developed and manufactured in line with the latest quality and safety
standards.
You should nevertheless take certain precautions during installation and operation.
Protect STATMATIC and any aerosols used from heating up to above 50° C.
SciCan original spare parts must be used for operation or repair as these have undergone extensive
safety, function and specific suitability testing. SciCan also accepts product liability for these parts.
Any modifications made by third parties and any installation of parts other than SciCan original
spare parts will lead to the expiry of warranty claims and authorizations.
Observe all warning notes on the device and in the Operating Instructions.
The device must be supplied only with the voltage noted in the Operating Instructions and on the
device.
Users must not attempt to service the device themselves beyond the points explained in the
Operating Instructions.
Instruments must be sterilized after maintenance with the STATMATIC. The manufacturer's
specifications for the instruments maintained as well as national guidelines must be complied with
during this process.

Purpose

The STATMATIC is intended for the internal cleaning, servicing and maintenance of handpieces,
angle pieces, air motors and turbines used in dentistry.
For further information about the suitability of certain instruments for maintenance, please consult
the manufacturer's instructions.

User qualification

The STATMATIC must only be used by specialist, practically trained and qualified personnel. During
the development and design of the STATMATIC we worked on the assumption that dentists and
their assistants were the target group.

Non-designated operation

The STATMATIC must only be used for the applications defined in the purpose.
The STATMATIC is not intended for operation in potentially explosive areas.

Disposal

Expendable materials:

The waste materials produced are harmless to humans and the environment. They must be
recycled or disposed of in compliance with the applicable national regulations.

Devices and accessories at the end of service life:

We point out that this product is subject to the EC Directive (2002/96/EC) for waste in electrical and
electronic equipment and that within Europe it must be disposed of in a specific manner.

2 Installation)

2 Installation

Environmental conditions

A series of factors can influence the performance of your STATMATIC. Please look closely at these
factors, then choose a suitable place for installing the device.

• Temperature and relative humidity

Do not install your STATMATIC in a place with exposure to direct sunlight or close to a source of
heat (e.g. heaters). The recommended operating temperature is between 5 and 40 °C with a relative
humidity of between 25 and 85%.

• Environment

The STATMATIC should be operated in a clean, dust-free environment.

• Work space

The STATMATIC should be installed on a flat, even, water-repellent and oil-impervious surface.
Do not install and operate the device on a sloping surface.*

• Electromagnetic environment

The STATMATIC has been tested for electromagnetic emissions and meets the applicable
standards. Although the device does not emit radiation, it may nevertheless be influenced by other
devices that emit radiation. We therefore recommend you to keep the device away from potential
sources of interference.

• Electrical requirements

Use correctly earthed and fused power sources within the nominal voltage range shown on the label
at the rear of your STATMATIC.
Avoid using multiple sockets. When using power strips with overvoltage protection, only ever
connect one STATMATIC to the power supply. The mains input plug on the rear of the device must
be used as an isolator from the mains power supply.

• Connections to utilities

Plug mains plug into socket.
Attach compressed air hose to coupling secure it.
The compressed air must display 4 - 4.5 bar on the manometer.
If anything other than this is displayed, pull out the handle on the pressure adjustment and turn it to
the right or left until 4 - 4.5 bar is displayed.
Push the handle on the pressure adjustment back in and lock it into position.
In order to ensure safe and trouble-free functioning, use only compressed air in accordance with the
specifications in Technical Data.
