General safety warnings
The manufacturer developed and constructed the appliance so that damage
would not occur when the appliance is used for its intended purpose. The
manufacturer considers it his obligation to describe the following safety
measures in order to avoid further damages.
•When operating the appliance, it is necessary to observe laws and
regional regulations valid in the place of usage. In order to ensure safe
course of works, the operator and user are responsible for the observation
of regulations.
•The original packaging should be kept for the possible return of the unit.
Only original packaging guarantees an optimal protection of the appliance
during transportation. If it would be necessary to return the appliance
during warranty period, the manufacturer is not responsible for damages
caused by incorrect packing.
•If an undesirable event occurs in the operation of appliance, the user is
obliged to immediately inform his supplier to this event.
•This product is not intended for use in areas with the risk of explosion.
Possible explosion hazard if the compressor is used in the presence of
flammable anesthetics.
•Never put oxygen or nitrous oxide into the compressor. The electrical
components are not approved for oxygen or nitrous oxide use.
•This device can be used only with ventilator equipped with low pressure
alarm.
Safety warnings regarding the protection agaist electric current
•The appliance must only be connected to an appropriate power source
that has correct grounding. Reliable earth ground can only be achieved
when equipment is connected to a receptacle marked "hospital grade".
•Prior the connecting the compressor, verify whether the mains voltage and
frequency specified on the apparatus are in accordance with the local
supply.
•Prior to putting into operation, check for possible damages on the
appliance and the air connectors. Damaged cables and sockets/plugs
must be replaced immediately.
•In the case of a dangerous situation or a technical failure, immediately
disconnect the appliance from mains supply.
•During all repairs and maintenance:
- ensure that the mains plug is removed from the power socket,
- pressure pipes must be air vented,
- pressure must be released from pressure tank.
•Only a qualified expert can install this appliance.

USAGE ON PURPOSE
•The appliance can be installed and operated only in dry, ventilated and
dust-free area. Climatic conditions for operation - see Technical data.
•The compressor must stand on a flat, sufficiently stabile base with.
•The compressor must not be exposed to rain. The appliance must not be
used in humid or wet environments. Furthermore, it is forbidden to use it in
the presence of flammable liquids or gasses.
•Prior to the connection of compressor to the respiratory appliance, it is
necessary to assess whether the available medium meets the
requirements of the given appliance of use. Please, refer to the Technical
data for this purpose.
•Usage, other than the compressors intended use is not considered to be
safe. The manufacturer is not responsible for the damages implied if the
compressor is used for other uses. Such a risk is assumed only by
operator/user.
STORAGE AND TRANSPORT CONDITIONS
The compressor is dispatched from the factory in transport packing with the
pump fixed. Thus the appliance is protected from damage during transport. P
During transport, if it is possible, always use the original packaging of the
compressor. Always transport the compressor up right.
During transport and storage, protect the compressor against humidity,
contamination and extreme temperatures. Compressors that have original
packaging can be stored in warm, dry and dust-free areas.
Keep the packaging material, if possible. If it is not possible, dispose of the
packaging material in an environment-friendly way.
The compressor can only be transported pressure-free. It is necessary to
release the pressure from the pressure tank and pressure hoses prior to
transport, and to release any possible condensatet. Secure motor inside
before shipping!
Prior to transport it is necessary to fix motor inside the compressor
(Chapter 5.)

19. Tube for supporting equipment
The appliance consists of an oil-free piston compressor driven by a single-
phase electric motor, of filtering and drying equipment, of a pressure tank
and of a pressure regulator. The compressor is placed in a box lined with
noise reducing material. The appliance thus produces filtered compressed air
without any traces of oil with reduced humidity contents.
The air compressor has an input, air fitting labeled WALL (9) that allows you
to connect to an outside air source. When an outside compressed air source
that is connected to the inlet WALL fitting supplies air above adjusted output
pressure the air pump will not be activated even though the power switch is
in the ON position. Instead, the air from the outside source will be directed to
the compressor's air output. When the outside air source pressure is less
than adjusted output pressure (or is not connected) and the power switch is
in the ON position, the air pump is activated and supplies compressed air
through the air output.
The air pump sucks the atmospheric air through air intake filter (12).
Compressed air is cooled in the cooler (15), continue in the filter (14) and
condensed liquid from the water trap is automatically released to the
evaporative tray. The air continues through the check valve to the pressure
tank (11) and through the pressure regulator with the output filter (13) to the
OUT (10). The fans operate while the air pump works, or also during the
pause, when the temperature in the cabinet is over 40°C (104°F). Any
increase of temperature in the cabinet over 80°C (176°F) - cooling failure - is
signalled by the red indicator (3) and by acoustic alarm. The Control
electronics (16) control running the air pump according to pressure in the
pressure tank (11). A safety valve (17) prevents the maximal allowable
pressure in the pressure tank.
