Special information on the unit itself
The symbol on the scale of contents gage 1is to remind
you that the pressure reducer must never be allowed to
come into contact with combustible substances (oil, alco-
hol, grease etc.), as these may cause explosive reactions
with oxygen.
Serial number (SN): The first two digits of the unit number indicate the year of
manufacture. The following five digits are used for consec-
utive numbering of the individual units.

1. Description
1.1 Purpose
The pressure reducers are for administering medical oxygen at reduced pressure for various
devices from the medical and therapy fields and for administering oxygen to the patient via
a system (e.g. nasal cannula, oxygen mask, humidifier). The pressure reducers are intended
for connection to high-pressure oxygen cylinders (up to 20,000 kPa = 200 bar cylinder
pressure).
The pressure reducers are not intended to drive surgical tools.
1.2 User qualification
Patients must be instructed in the use of the device by qualified personnel before therapy
begins.
1.3 Function
During use, the oxygen from the cylinder passes through the cylinder valve and connecting
union 2into the body 3of the pressure reducer. The cylinder pressure (inlet pressure) can
be read on the contents gage 1.
A filter screw with an integrated sintered filter removes any impurities. Another sintered
filter reduces the flow of oxgen. The filter screw 11 is located in the opening of connecting
union 2. The second sintered filter is installed between connecting union 2and body 3.
In the reduction stage, cylinder pressure is reduced to the operating pressure (outlet pres-
sure) required in each case of between 0.5 and max. 5.5 bar, depending on type . The prin-
ciple used here, with crater-type bore and spring-loaded piston, ensures particularly
constant pressure, despite variations in flow.
All pressure reducers are protected against excessive pressure by a safety valve 10.
The following pressure reducers are described in these operating instructions:

8Description
EN
Fixed pressure reducer (Fix)
A constant flow is generated by a fixed orifice in oxygen
outlet 5.
The pressure reducers listed above differ in the length and
position of the connecting union 2.
Variable pressure reducer (Fine)
The piston is acted on by a second spring which is adjust-
able by means of a spindle system. This makes it possible
to set different operating pressures (outlet pressures). In
conjunction with the fixed orifice in oxygen outlet 5, you
can therefore set different flow rates. The flow setting is
read off at flow gage 6.
The pressure reducers listed above differ in the length and
position of the connecting union 2.
Multistep pressure reducer (Fast)
As in the fixed pressure reducer, these produce a constant
operating pressure (outlet pressure).
Multistep adjuster 4houses an orifice disk with orifices of
different diameters which are brought into line with oxy-
gen outlet 5by means of a locating system. This enables
you to set different flow rates.
The pressure reducers listed above differ in the length and
position of the connecting union 2.
Multistep pressure reducer (Fast II High Flow)
As in the Fast multistep pressure reducers, there is an ori-
fice disk with a variety of orifice diameters in adjuster 4
which is brought into line with oxygen outlet 5by means
of a locating system.
In addition to the flow outlet, there is a pressure outlet for
medical devices with an oxygen requirement in excess of
90 l/min. The pressure outlet and the flow outlet may not
be in operation simultaneously.

Oxygen outlets
Oxyway pressure reducers are available with different oxy-
gen outlets: variable pressure outlet and flow outlet (see
also “10. Technical Data” on page 29).
Flow outlets are intended for the direct supply of the pa-
tient, e.g. via nasal cannula, mask or intermediate humid-
ifier. Flow outlets have a 9/16 UNF thread.
Pressure outlets are intended to supply ventilators such as
the Medumat, modules or distributor bars. Pressure out-
lets have a G 3/8" thread.

2. Safety Information
2.1 Safety provisions
For your own safety, the safety of your patients, and to comply with the requirements of
EU Directive 93/42/EEC, please observe the following points:
General
Caution!
• Read these operating instructions carefully. They are part of to the pres-
sure reducer and must be available at all times.
• Before working with the pressure reducer, you should understand how
it works. In the event of queries, contact your authorized dealer or the
manufacturer.
• Use the pressure reducer for the designated purpose only (see “1.1
Purpose” on page 7).
• Have all inspection and servicing work carried out by the manufacturer
(Weinmann) or by a trained authorized dealer.
• If third-party items are used, functional failures may occur and fitness for
use may be restricted. Biocompatibility requirements may also not be
met. Please note that in such cases, any claim under warranty and liability
will be voided if neither the accessories nor genuine replacement parts
recommended in the instructions for use are used.
• A spare unit must always be kept handy in case of failure.
• Please observe the section “5. Hygienic preparation” on page 19 in order
to avoid infection or bacterial contamination.
•Inadequate supply of oxygen possible.
Never use pressure reducers with a flow outlet to operate medical devic-
es. The supply pressure of the flow outlets is inadequate for this and
could result in malfunctions or failures of the medical devices and thus in
a risk to the patient.
•Inadequate supply of oxygen possible.
With oxygen requirements in excess of 90 l/min, the pressure outlet and
the flow outlet may not be in operation simultaneously.
