1.2 Function
• The AtmoSafe is an electrically operated medical device,
cleaning the air in medically used rooms from fume and
gas constituents arising from vaporising of human or
animal tissue. This fume arises typically when using laser
or electro-surgical devices and is consisting as a rule of
water vapour, aerosol, and organic gases.
• The AtmoSafe improves the environmental conditions in
the operating theatre:
- Reduction of the dust load by removing respirable
particles
- Improvement of view
- Removal of foul-smelling and partly toxic organic
gases
- Evacuation and ltering of hazardous bio-aerosol
(ltration of viruses)
• The AtmoSafe draws in the fume-laden air through a de-
vice positioned at the surgical application part or through
a separate hose, manually held near the application part.
By means of a high-efciency lter the drawn-in air is
cleaned of the hazardous matter and returned again into
the ambient air.
• Cleaning of the air refers to constituents like aerosol,
which is being retained by means of an ULPA high-efciency particle lter, as well as to organic gases, which,
amongst other characteristics, feature a smell unpleasant
for human beings, retained by a special gas lter.

5.0 Operation
5.1 Initial starting up
Prior to shipment each AtmoSafe is being inspected by the manufacturer for function and safety.
In order to make sure that the appliance is working safely after transport and installation, the
following points should be observed: The user should put the appliance into operation only if the
manufacturer or the supplier
Peruse safety information in part 2.0 prior to starting up the device for the rst time.
1. has carried out a functional test on the appliance at the place of operation
2. has instructed the person responsible for operating the device on how to handle the device
by means of the operating instructions.
6h
14
Following transportation at low temperatures (<0°C) the appliance must be held for up to six
hours at ambient temperature before rst start-up. When the device has not been acclimatised
evacuation cannot be activated The device is protecting itself.
5.2 Assembly
The device has to be positioned on a stable base; attention must be paid to the load carrying
capacity.
The base must not be soft (foamed material or similar), so that the exhaust air openings are not
covered.
5.2.1 Installation together with a surgical device
The power cable of the surgical device must be tted with an inlet connector for non-heating apparatus according to IEC 320.
This inlet connector for non-heating apparatus is plugged into the auxillary mains socket (, Fig.
3) on the rear of the AtmoSafe. The AtmoSafe is now controlling the power input of the surgical
device by means of the internal ISA device (Internal Synchronous Activation) and, in this way,
effects auto activation. Auto activation means that the evacuation mode is switched on as soon as
the thermal surgical function of the surgical device (Cut, coag,...) is activated.
Prior to rst use of the surgical device auto activation must be calibrated once. How the AtmoSafe
is to be adapted to the surgical device is said in Chapter 5.7.5 Calibration of auto activation.
10
Auto activation of the AtmoSafe works with most surgical devices in the power range 50 W...1400
W (for inst. ERBE ICC 350, ICC 50,...)
Only compatible devices may be connected to the auxiliary mains socket (,Fig. 3).
5.2.2 Main lter
• After having taken off the packaging and the plugs, please slide the main lter (, Fig. 1, p. 15)
into the lter shaft of the unit until it locks. Take care that the lter cover is on the right side.
When there is no main lter in the unit evacuation cannot be activated.
