Ambient conditions:

• Transport / storage:

- -10...+50°C;

- 30...95 % air humidity without condensation

- at an air pressure of 500...1060 hPa

• Operation:

- +10..+35°C;

- 30...95 % air humidity without condensation

2.0 For your safety

For your safety

• The Chair E 2 has been designed in accordance with IEC 601/ EN 60601. The equipment conforms to VDE Safety Class I and must only be connected to a properly installed earthed socket.

• The Chair may only be used in supervised operation (IEC 60601-1 / EN 60601-1).

• Prior to  rst start up, check whether the supply voltage indicated on the chair corresponds to the value of your local power supply.

• For mains supply, only use the power cable supplied (or an equivalent one).

• Check proper assignment when assembling country-

speci c connections:

- green / yellow: protective conductor

- blue: neutral conductor

- black or brown: phase

• Prior to  rst starting up, all connecting leads must be checked on damage. Damaged cables must be replaced.

• To disconnect the chair from the power supply,  rst remove the plug from the safety connection socket. Then disconnect the connection line from the chair. Never touch plug or cables with wet hands.

• Please observe the ambient conditions stated in the technical data (chapter 7.0).

• The Chair E 2 is not designed for the use in medical areas

with an explosion hazard. Explosion-hazardous areas

may be caused by the use of  ammable anaesthetics,

skin cleansing products and skin disinfectants.

• Ensure that the patient sits in the middle of the seat. A constant unilateral strain on the seat can damage the surface.

• The user must be familiar with the operation of the chair.

• ATMOS is not liable for personal injury and damage to property if

- no original ATMOS parts are being used,

- the advice for use in these operating instructions is not being observed.

• 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.

• The electric motor is protected by an integrated thermal protection switch. After 1.5 minutes of continued operation, the motor requires a cool down period of approx. 8.5 minutes. If the thermal protection switch is activated, the motor requires a cool down period of approx. 20 minutes.

3.0 Setting up and starting up





3.1 Assembly

• Always place the device on a level, safe surface.

Mains voltage and fuse:

Mains voltage: 230 V / 50 Hz (120 V / 60 Hz)

Fuse:

• Thermal fuse: 3 A (230 V)

• Thermal fuse: 6 A (120 V)

3.2 Starting up

• Position the chair at the allocated space. Any  oor

unevenness must be compensated for.

• Check that the upper part of the chair can rotate freely.

• Peruse safety information in part 2.0 prior to starting up the

device for the  rst time.

• Finally, connect power cable.

3.3 Electrical connection

The ATMOS® Chair E 2 is supplied with a power cable and IEC connection. The power cable is plugged into the IEC connection on the rear side of the base and is connected to a properly installed earthed socket.

The electrical connection values (voltage and nominal frequency) as well as the data for fuses can be found on the type plate above the connecting socket.

Disconnection from the power supply is only possible by pulling the power plug!

 There is no indication that the device is powered!

 In the case of non-use, service and repair work and

cleaning, the chair must be disconnected from the power supply by pulling the power plug.

4.0 Operation

The height adjustment is controlled via the two foot switch buttons marked with arrows. The left foot switch button is for the upwards movement, the right for the downwards movement.

The arm rests can be folded backwards; that makes it easier for handicapped persons to be transferred from the wheelchair to the examination chair.

The backrest inclination can be controlled by means of the control elements attached to the side of the backrest.

Arm rests, foot support and backrest are coupled for synchronous movements.

The electric motor is protected by an integrated thermal

protection switch. After 1.5 minutes of continued operation, the motor requires a cool down period of approx. 8.5 minutes. If the thermal protection switch is activated, the motor requires a cool down period of approx. 20 minutes.

4.1 Positioning the patient

Ensure that the patient sits in the middle of the seat.

A constant unilateral strain on the seat can damage the surface.

4.2 Adjusting the seat height

The seat height adjustment is controlled by the 2 foot

switches ( g.2):

5.0 Cleaning and care

5.1 General information on cleaning and disinfection

Prior to cleaning

Medical chairs like the ATMOS® Chair E 2 must always be operational and reliable.

Therefore, we recommend:

Prior to each use:

if required

 The described measures relating to cleaning and

disinfection resp. sterilisation do not replace the relevant instructions which must be adhered to prior to operation!

• For disinfection, you may use all surface and upholstery disinfectants listed in chapter 5.3 and 5.4 “Recommended disinfectants”.

 Always observe the concentration speci cations and

instructions by the respective manufacturer!

• Do not use

- Disinfectants which contain organic or inorganic acids or bases as they could cause corrosion damage.

- Disinfectants containing chloramides, phenol derivatives or anionic tensides, as these may cause stress cracks in the material used for the housing of the unit.

5.2 Cleaning and disinfection of the device surface and upholstery

If liquid has penetrated the device, it may not be operated again until it has been checked by the authorised customer service centre.

• The surface of the ATMOS Chair E 2 is resistant against all the recommended surface disinfectants stated in chapter 5.3

and 5.4. Nevertheless after a longer period of use discolouration could occur. Polar solvents (e.g. acetone or chlorinated hydrocarbons (CC)) may not be used for cleaning and disinfection.

• Disconnect the power plug from the power supply prior to cleaning and disinfecting the device surface.

• The device itself can be wiped off with a moist (not wet) cloth.

• Substances such as blood must be removed immediately to prevent stains.

Do not use aggressive or abrasive cleansing agents. For the upholstery standard dry foam may be used.

Treatment with a commonly used care product for arti cial leather is recommended once a week in order to keep the upholstery

soft and smooth.

5.3 Recommended surface disinfectants

The surfaces of the ATMOS® Chair E2 can be cleaned / wiped with disinfectants containing the following active ingredients:

• QAV (quaternary ammonium compounds)

5.4 Recommended disinfectants for the upholstery

Disinfectant Ingredients in 100 g Manufacturer

Green & Clean SK Di alkyl dimethyl ammonium chloride < 1 g Metasys, Rum (Austria)

Alkyl dimethyl ethyl benzyl ammonium chloride < 1 g Alkyl dimethyl benzyl ammonium chloride < 1 g

Within the frequency range of 150 kHz to 80 MHz the eld strength should be below 3 V/m.

11.4 Recommended safety distance between portable and mobile RF Communications equipment and the ATMOS® Chair E 2

The ATMOS customer or user of the ATMOS between portable and mobile RF Communications equipment and the ATMOS the maximum output power of the communications equipment.

Chair E 2 is intended for use in electromagnetic environment in which radiated disturbances are controlled. The

Chair E 2 can help prevent electromagnetic interference by maintaining a minimum distance

For transmitters for which the maximum nominal output is not indicated in the above table, the recommended safety distance d in meters (m) can be determined using the equation belonging to the respective column whereas

P is the maximum nominal output of the transmitter in watts (W) acc. to manufacturer's specication.

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 emanation of electromagnetic waves is affected by

absorption and reection of buildings, objects and people.
