For your safety
● The ATMOS® Chair 31 P may only be operated in rooms
used for medical purposes, but not in areas subject to
explosion hazards. Explosion harzards may result from
the use of combustible anaesthetic agents, skin cleansing
agents or disinfectants.
● The ambient conditions specifi ed in section 9.0
"Technical specifi cations" must be strictly observed!
®
● To guarantee safe operation of the ATMOS
must be screwed tightly onto the fl oor. To avoid damages,
check, prior to this fi xing, whether there are feed lines
(heating, current, water etc.) in the fl oor.
● Before connecting the device to the power line, check
that the voltage and frequency ratings of the power line
correspond to those indicated on the type plate.
● Ensure that your patients sit in the middle of the seat.
A constant unilateral strain on the seat can damage the
surface.
● For current entry, only the supplied power cable (or an
equivalent one) may be used.
● Correct configuration in assembly of country-specific
connections:
green/yellow protective conductor (PE)
blue neutral conductor (N)
black resp. brown phase (L)
● Prior to every application of the equipment make sure that
all connecting lines are technically safe and in proper condition. Damaged leads must be replaced immediately!

● Before the patient takes a seat, when he gets up
from the chair and prior to starting the examination
(after positioning of the patient), make sure that the
swivel joint is arrested (multifunction lever in top
position).
● ATMOS neither guarantees error-free function nor
is ATMOS liable for personal injury and damage to
property if
• original ATMOS parts are not being used,
• the advice for use in these operating instructions
is not being observed,

and repairs have been carried out by personnel
not authorised by ATMOS.
● The warranty will be rendered invalid in case of da-
mages caused due to the utilization of accessories or
consumables which are not approved by ATMOS for
use with this chair.
● Please note:
A medical insulating transformer with earth leakage
monitor or any similar safety system acc. to EN 60
601-1 is required, if several devices are connected
over one common power supply. The transformer
must correspond to the power consumption of all the
devices to be connected.
● When connecting several devices to an insulated
ground receptacle, the allowed strain and leakage
current have to be observed!
Prior to use a visual inspection is required. If any
parts are defective the ATMOS

First of all press the collar bushings (503.0735.0) from inside,
on the left and right, into the front drillings of the seat base
frame. Afterwards bring the upper part of the pre-assembled
component (with the fold-away foot plate in front) in correct
position between the two bushings. Feed the axis (197 mm
length, REF 503.0721.0) through the drillings of the seat
base. A plain washer is installed on either side and the retaining washer is slided into the groove of the axis.
Press the collar bushing (503.0736.0) from outside into the
stiffener. Remove retaining washer and washer from the
axis at the lower bottom end of the seat frame. Pull the axis
back to the right. Lift the stiffener and bring it into the correct
position with the axis and slide it forward again. Afterwards
the plain washer is installed on either side and the retaining
washer is slided into the groove.
3.5 Fixation of the back rest
Insert the back rest into the provided opening. The round
bolts are locked into place in slightly tilting them forwards (

Always observe the concentration specifi cations and
instructions by the respective manufacturer.
● In chapter 5.3 Recommended disinfectants“ all sur-
face and instrument disintectants are stated which are
suitable for disinfection.
● Do NOT use
- disinfectants containing concentrated organic
or anorganic acids or bases, since these may cause
corrosion damages.
- disinfectants containing chloramides, phenol
derivatives or anionic tensides, since these may
cause stress cracks in the plastics used.
5.2 Cleaning the unit's surfaces and upholstery
● The surfaces of the ATMOS
5.3 and 5.4. Nevertheless after any length of time discolourations could possibly develop.
● Substances such as blood need to be removed immediately to prevent stains on the cover material of the upholstery.
● The unit itself can be wiped off with a moist (not wet) cloth.
Do not use any abrasive cleaning agents. For the upholstery usual dry foam may be used.
Treatment with a commonly used care product for artifi cial leather is recommended once a week in order to keep the
upholstery soft and smooth.

d = (3,5 / V1) * √(P)
d = (3,5 / E1) * √(P) 80-800 MHz
d = (7 / E1) * √(P) 0,8-2,5 GHz
where „P“ is the max. power in watts (W)
and D is the recommended separation
distance in meters (m).
Field strengths from fi xed transmitters, as
determined by an electromagnetic site (a)
survey, should be less than the compliance level (b).
Interference may occur in the vicinity of
equipment containing following symbol.
11.0 Notes on EMC
NOTE 1 With 80 MHz and 800 MHz the higher frequency range applies.
NOTE 2 These guidelines may not be applicable in all cases. The propagation of electromagnetic sizes is
infl uenced by absorptions and refl ections of buildings, objects and people.
a The fi eld strength of stationary transmitters, such as base stations of cellular phones and mobile terrain radio
equipment, amateur radio transmitters, cbm broadcast and TV stations cannot be exactly predestined.
To determine the electromagnetic environment in regard to stationary transmitters, a study of the location
should be considered. If the measured fi eld strength at the location where the ATMOS
is used exceeds the above compliance level, the ATMOS® Chair 31 P is to be observed to
verify the intended use. If abnormal performance characteristics are noted, additional measures might
be necessary, e. g. a changed arrangement or another location for the device.
b Within the frequency range of 150 kHz to 80 MHz the fi eld strength should be below 3 V/m.
11.4 Recommended separations between portable and mobile RF Communications
equipment and the ATMOS® Chair 31 P

The ATMOS
are controlled. The customer or user of the ATMOS® Chair 31 P can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF Communications equipment and the ATMOS® Chair 31 P as recommended below, according to the maximum output power of the communications
equipment.
