The CAIRE Liberator is the stationary component of the
Liberator/Stroller supplementary oxygen system. The
Liberator incorporates a stainless steel cryogenic container
with the valves, plumbing, and associated hardware required
to deliver gaseous oxygen to the patient at near ambient
temperature.
The Liberator is comprised of four major assemblies.
Grouped according to function, they are:
1. Cryogenic Container – This assembly is a double walled,
vacuum insulated dewar for storing liquid oxygen at approximately -300 degrees Fahrenheit. The inner pressure vessel is designed to safely hold liquid oxygen and
is protected from over pressurization with the primary relief valve. The vacuum insulation between the inner and
outer vessel keeps the outside heat from evaporating the
cold liquid
2. Breathing Circuit – This circuit consists of the manifold
assembly, fixed orifice rotary flow control valve (FCV),
a breathing coil, and a warming coil. It withdraws liquid
oxygen from the cryogenic container, warms it to near
ambient temperature, and meters the oxygen gas to the
patient. The water that is formed when the cold liquid is
converted to gas is collected in the condensate bottle.
An economizer regulator is used to reduce any excessive head pressure while oxygen is being provided to the
patient.
3. Shroud Assembly – The shroud assembly houses and
protects the breathing circuit and liquid level meter.
Labels listing safety information and patient operating
instructions are affixed to the side of the shroud.
4. Meter – This system uses a capacitance probe and an electronic level meter (LED) readout to measure and display
the product contents at the touch of the meter switch.
An optional roller base can be provided to help move
the Liberator.

Oxygen, as it exists at standard atmospheric pressure and
temperature, is a colorless, odorless, and tasteless gas.
Oxygen constitutes 21% of the atmosphere, by volume. Aside
from its well-documented ability to sustain life, oxygen also
supports combustion, even though it is nonflammable. Many
substances which will burn in air, burn at a faster rate and at
a higher temperature in an oxygen enriched atmosphere. A
few materials that do not burn in air will burn as the oxygen
concentration increases. Some greases and many liquid solvents become extremely hazardous materials when placed in
an oxygen-enriched environment. In its liquid form, oxygen
is still odorless and tasteless, but is now pale blue in color.
At an operating pressure of 20 psig, the temperature of liquid oxygen is about -280° Fahrenheit. Skin exposed to such
a low temperature can become severely frostbitten.
These hazards require that certain safety precautions be taken
when working with or around gaseous and/or liquid oxygen:
1. Never permit combustible substances such as greases,
oils, solvents, or other compounds not oxygen compatible to contact any component of the unit exposed to
higher-than-atmospheric concentrations of gaseous or
liquid oxygen. This especially applies to tubing, fittings,
and valves.
2. Keep the oxygen equipment away from open flames or
electrical appliances such as heaters, stoves, toasters,
and other devices with heating elements.
3. Never permit smoking in an area where oxygen equipment is repaired, filled, or used.
4. Always wear goggles, a face shield, and insulated gloves
when working with or around liquid oxygen.
While CAIRE equipment is designed and built to the most
rigid standards, no piece of mechanical equipment can ever
be made 100% foolproof. Strict compliance with proper
safety practices is necessary when using a Liberator or
Stroller. We recommend that our distributors emphasize
safety and safe handling practices to their employees and
customers. While safety features have been designed into the
unit and safe operations are anticipated, it is necessary that all
distributor personnel carefully read and fully understand
WARNINGS, CAUTIONS, and NOTES throughout the man-
ual. Periodic review of this information is recommended.
WARNING: Excess accumulation of oxygen creates an oxygen-enriched atmosphere (defined by the Compressed Gas
Association as an oxygen concentration above 23%). In an
oxygen-enriched atmosphere, flammable items may burn vigorously and may explode. Certain items considered non-combustible in air may burn rapidly in such an environment. Keep
all organic materials and other flammable substances away
from possible contact with oxygen; particularly oil, grease,
kerosene, cloth, wood, paint, tar, coal dust, and dirt which
may contain oil or grease. DO NOT permit smoking or open
flame in any area where oxygen is stored, handled, or used.
Failure to comply with this warning may result in serious
personal injury.
WARNING: In the event a unit is dropped, tipped over, or
unreasonably abused, immediately, but cautiously, raise the
container to its normal vertical position. If substantial container damage has occurred, remove the liquid oxygen from
the vessel in a safe manner (RP 24). Purge the unit with an inert gas (nitrogen) and promptly return it to CAIRE for inspection. The container should be prominently marked
“CONTAINER DROPPED, INSPECT FOR DAMAGE.”
Failure to comply with these procedures may result in personal injury and can seriously damage the container.
WARNING: Personnel must remove liquid oxygen and depressurize the Liberator or Stroller before removing parts or
loosening fittings from a unit. Failure to do so may result in
personal injury because of the extreme cold of the liquid oxygen and the pressure in the vessel. External valves and fittings
can become extremely cold during liquid transfer.
WARNING: During transfer of liquid oxygen, components
will become extremely cold. Care should be used to avoid any
contact with these components, as serious burns may result.
WARNING: Keep filled unit upright at all times. Tip over
of filled unit may result in liquid oxygen leakage and/or oxygen enriched atmosphere.
WARNING: Only use replacement equipment which is compatible with liquid oxygen and has been cleaned for oxygen
use. Do not use regulators, fittings, hoses, etc. which have
been previously used in a non-oxygen service.
CAUTION: The Liberator should be moved by utilizing the
roller base or hand truck. The Liberator must be used, stored,
and transported in a vertical position. Do not lay, store, or
ship on its side.
IVTheory of Operation
Page 7
Filling
The Liberator is filled by connecting a pre-purged transfer
line with a fill adapter from a larger liquid oxygen source to
the Liberator female (side fill) or male (top fill) quick disconnect valve. The Liberator vent valve is opened. The pressure of the oxygen gas above the liquid in the source container forces liquid oxygen through the transfer line and into
the Liberator inner vessel.
There will be some oxygen vaporized during filling. This
gas is discharged through the vent valve. When the Liberator
is full, liquid oxygen is expelled. Closing the Liberator vent
valve and disconnecting the fill adapter from the Liberator
QDV terminates the fill process.
Saturation Pressure
The saturation point of a liquid is a steady-state condition
where the liquid has absorbed the maximum amount of heat
it can. Such a liquid is defined as being at its saturation pressure. For each saturation pressure, there is a corresponding
temperature; the higher the saturation pressure, the higher
the liquid temperature.
There are two conditions which can seriously affect the
overall efficiency and operation of the system:
1. Saturation pressure of the liquid oxygen in the fill source
is substantially higher than the Liberator operating pressure (oversaturated).
2. Saturation pressure of the liquid oxygen in the fill source
is substantially lower than the Liberator operating pressure (undersaturated).
For example, when a Liberator is filled from a liquid source
saturated at 100 psig, larger transfer losses will occur. This
is because the Liberator is designed to operate at 20 psig,
and the liquid it is filled with is saturated at a much higher
pressure and at its correspondingly higher temperature. It is
necessary for this liquid to desaturate to a lower pressure and
temperature before the relief valve will close and the
Liberator will operate properly.
In order to become saturated at 20 psig, the liquid oxygen
must give up enough heat for its temperature to be lowered
to that temperature corresponding to a pressure of 20 psig, as
shown in the graph. It accomplishes this by a vigorous boiling action. All of the gas generated by this boiling is vented
through the primary relief valve, and is lost.
If the saturation pressure of the liquid oxygen in the filling
vessel is lower than the normal operating pressure of the
Liberator, e.g., 10 psig, then the pressure building rod of
the Liberator must function to raise the system pressure to
the operating pressure of 20 psig. It may require as much as
several hours for the undersaturated liquid to become saturated at 20 psig. The time required for saturation to 20 psig
depends on the initial liquid saturation pressure.

WARNING: Low oxygen flow rates to the patient may
result if the Liberator is filled with under-saturated liquid oxygen.
To minimize the effect of undersaturated liquid on the
Liberator, a fixed orifice has been installed in the outlet of
the vent valve. This orifice regulates the back pressure in the
unit during the fill process, resulting in more correct saturation pressures in the Liberator.
Operation
With liquid oxygen in the unit and the flow control valve and
vent valve closed, the pressure in the inner vessel will remain
near the primary relief valve setting of 23 psig.
In the Liberator, as in all vacuum-insulated cryogenic containers, some liquid (oxygen in this case) is always evaporating into a gas because no insulating system is perfect.
The rate of generation of this gas, with the flow control
valve closed, is called the normal evaporation rate (NER).
This gas is lost through the primary relief valve.
When the flow control valve is at any setting other than off,
and the economizer valve is open (pressure above 20 psig),
gaseous oxygen is forced from the head space in the inner
vessel, through the economizer valve, to the breathing coil.
This process conserves or “economizes” liquid oxygen by
withdrawing the head gas first, instead of allowing it to escape through the relief valve.
In the breathing coil, the cold gaseous oxygen is warmed to
near-ambient temperature while flowing to the flow control
valve, where it is metered and dispensed.
Whenever gas is removed from the space above the liquid
oxygen, the inner vessel internal pressure begins to drop
slightly. When the pressure drops to 20 psig, the economizer
valve closes, forcing liquid oxygen up the withdrawal tube
and through the warming coil where it becomes gas.
The gas then flows through the bypass tee to the breathing
coil, the flow control valve, and then the patient.
As the pressure in the container increases over 20 psig, the
economizer valve opens, and the cycle repeats, maintaining
constant oxygen flow, at the set flow rate, to the patient.

Liquid Level Measurement
Liberators are equipped with a unique liquid level measurement system. This system measures the level of liquid oxygen
inside the unit with a capacitance probe and displays that liquid level on an LED bar graph meter called "Sur-Cal 3".
The liquid level probe consists of two concentric stainless
steel cylinders, which are inside the inner vessel. As the liquid oxygen level rises, the capacitance of this assembly goes
up. The meter measures this capacitance and displays it on
the LED bar graph.
Electrical connection between the Sur-Cal 3 meter and
the probe is made via a single conductor plug connector. The
male plug carries the coaxial cable from the meter. The female receptacle carries the same wire from the probe. A single ground wire is connected from the meter to a male spade
terminal on the corresponding meter ground wire. The SurCal 3is equipped with a short-circuit indicator which turns
all LED’s “off” when capacitance above approximately
375pF is reached.
The meter is powered by a nine volt battery. The meter has
a low battery (LOW BATT) indicator which signals the need
for battery replacement.

Transport
CAUTION: Always ship, store, or transport a Liberator,
empty or full, in an upright position, properly secured to prevent damage.
Specifically designed roller bases are available for moving
the Liberators short distances on smooth surfaces. Hand
trucks are also available for moving the Liberators.
The Liberator 20, 30, 37, 45 and 60 may be moved about or
transported in a vehicle while full without damage. However,
the equipment should not be dropped or handled roughly, or
necktube damage may occur.
Filling
1. Fill Source
a. Fill source must contain a sufficient amount of liquid
oxygen to completely fill the Liberator (approximately
120% of Liberator volume).
b. The liquid oxygen in the fill source must be saturated
at 35-60 psig (50 psig is optimal).
c. The fill source must have correct fitting (5/8” * 45°
male flare) to connect to transfer line.
WARNING: Fill source must be in a well ventilated area
to prevent formation of oxygen enriched atmosphere.
2. Fill Procedure
a. Required Equipment:
♦ Fill source as outlined above
♦ Liquid oxygen transfer line
♦ Male transfer line adapter for side fill Liberators
♦ Female transfer line adapter for top fill Liberators
♦ Liberator vent valve wrench
♦ Eye protection
♦ Insulated gloves
b. If refilling partially filled Liberator, verify flow rates are
within tolerance specifications before filling.
c. Verify that liquid level meter is operating properly. The
LED display should indicate approximate level in unit.
The low battery LED should not be lit.
NOTE: If flow rates are out of specifications or liquid
level meter operates improperly, refer to Troubleshooting/
Repair section.
d. Verify that fill source has enough properly saturated
(35-60 psig) liquid oxygen to fill Liberator.
e. Connect transfer line to fill source. Connect proper
transfer line adapter to transfer line.
f. Fully open liquid valve on fill source.
WARNING: Wear insulated gloves and eye protection whenever working with liquid oxygen.
VIII Operation
Page 12
g. For male fill adapter:
Purge transfer line by placing adapter poppet (remove
protective cover) against side of unit and pressing in until poppet opens. Hold the poppet open for approximately five seconds, then release.
NOTE: Purge the transfer line any time fill source valve
has been closed.
h. Wipe reservoir fill connector with lint free rag if moist.
i. Weigh unit as required by local and federal standards.
j. Open reservoir vent valve.
k. Connect transfer line (liquid hose) to reservoir to begin
fill.
l. Connect a pressure gauge to oxygen outlet and open
the flow control valve to 2 lpm or greater.
m. While filling throttle the vent valve as required to keep
pressure at 20 psi nominal.
An alternate method to throttle the vent valve is to attach a flow meter to the oxygen outlet, set the flow control valve to 2 lpm, and then throttle the vent valve to
maintain a flow of 2 lpm. This is equivalent to using a
pressure gauge.
n. When liquid spurts from vent outlet, disconnect trans-
fer line.
o. Close reservoir vent valve immediately after removing
transfer line.
p. Disconnect pressure gauge (or flow meter) from oxygen
outlet.
CAUTION: Do not allow excessive venting of liquid
oxygen through the vent valve. Prolonged exposure may
freeze the valve in the open position.
q. Replace protective cover on adapter QDV and hang
adapter and transfer line using hook provided.
r. Verify that all flow rates are within tolerance specifi-
cations. Verify that liquid level meter indicates full.
NOTE: The liquid level indicating system is accurate
only after the vent valve is closed, and the oxygen has
been stabilized for five minutes.

Routine Maintenance/Schedule B, Continuous
Page 14
Schedule B – Continuous
A. Introduction
Continuous maintenance is a set of test or inspections done
consistently to assure equipment is functioning properly. It
can be done with equipment in service, by drivers or other personnel.
1. If a unit fails to pass a given test, it should be taken out of
service and sent to the Repair Center/Department for further inspection.
2. Schedule – Checks are made when the driver sees patient
and when moving equipment between patients.
B. Procedure
These inspections/ tests are done by driver as part of the
Standard Fill Procedure every time the reservoir is filled.
1. Visual Inspection:
a. Broken shroud.
b. Cold sweaty bottle (vacuum problem).
c. QDV not deformed.
2. Check prescription flow rate(s). Erie liter meter (± 0.25
lpm) can be used.
3. Check meter. Push meter button before fill and verify that
battery is not low and that meter is within one LED of
table below. After filling, verify that meter reads full.
These inspections/tests are done between patients.
1. Visual Inspection:
a. Broken shroud/flow control knob.
b. Cold sweaty bottle or excessive venting from relief
valve (vacuum problem). Some venting from relief
valve is normal.
c. QDV not deformed.
d. Inspect under shroud (without removal) for any visible
dirt or contaminants.
e. Inspect drain tube for visible dirt. Clean with a 6” cot-
ton swab to remove dirt.

X Repair Procedures
RP1 – General
The following procedures have been carefully prepared to
allow proper removal and replacement of defective components and should be used in conjunction with the
Troubleshooting Chart and the tests in this section.
WARNING: Make sure the unit is empty and vent valve is
open before replacing any component, except shroud assembly components or Lip Seals.
WARNING: The worker’s hands, tools, and clothing
should be free of all oils and greases.
WARNING: Parts that are welded in place must not be replaced in the field. Should these parts fail, return complete assembly or sub-assembly to factory for repair. DO
NOT use solder or silver solder to repair broken welds.
WARNING: The manufacturer of Krytox warns users not
to allow Krytox fluorolubricant to contaminate tobacco
products. Wash Krytox from hands before smoking.
WARNING: Do not use glues, thread locking compounds
or unapproved sealants on any repairs.
CAUTION: When replacing components, make sure that new
part is oriented exactly the same as original part prior to installation.
CAUTION: Some components require a specific amount of
torque when assembling. Follow torque requirements where
specified.
NOTE: All replacement parts must be factory approved,
cleaned for oxygen service, and stored in sealed plastic bags.
The repair area must be clean and separate from other areas.
Room air should be filtered, and as free from dust, soot, and
other contaminants as possible.
NOTE: When replacing components with pipe threads, use
TEFLON tape thread sealant. Apply two rounds of TEFLON
tape to threads near end of component, avoiding first thread.
NOTE: When assembling new compression fittings, tighten
1/8", 1/4" and 1/2" nuts eight flats after finger tight and 3/16"

3. Adjust regulator to 20 psig. Open vent valve (Item 41)
to allow slow venting.
4. Allow Liberator to vent until 1-1/2 hours minimum
after vent valve (Item 41) defrosts.
RP26 – Flow Rate Test
NOTE: For flow rate test Liberator needs only to be 1/4 to 1/2
full.
a. Connect FCV outlet to flow meter inlet with respiratory
tubing. Make sure flow meter outlet is open and unobstructed and flow meter (Item G) is properly positioned.
b. Unit should operate for 1-1/2 hours minimum (overnight
is optimum). Test flow rate at each FCV (Item 24) position. Record all flow rates.
c. Flow rates must be nominal values within tolerances
listed in Specification section of this manual or unit fails
flow rate test.
NOTE: Be careful to allow for accuracy tolerances of
flow meter.
RP27 – Operating Pressure Test
a. Assemble pressure gauge (Item H) and adapter (Item J)
(use TEFLON tape).
b. Connect gauge assembly to DISS fitting on FCV outlet.
Open FCV (Item 24) to 6 lpm setting.
c. Read operating pressure on pressure gauge (Item H).
d. Operating pressure must be 18-22 psig or unit fails test.
RP28 – Flow Meter Verification
a. Flow meter accuracy is best verified by calibration lab-
oratory. Equipment should indicate liter per minute oxygen gas at 14.7 psia (0 psig) and 70° F.
b. Flow meter accuracy may also be tested by comparison
to one or more new, unused flow meters. This method
will increase confidence in accuracy of readings, but not
necessarily verify accuracy.
NOTE: If testing operating
pressure because of improper
flow rates, test immediately
after flow rate test.

When a Liberator is received, it should be inspected immediately, as outlined in Section VII, Unpacking and Setup
Instructions.
If a problem with the unit should be encountered, reference
should be made to the Troubleshooting Chart in Section X,
page 16-17. If these procedures do not provide a solution for
the problem, the following steps should be taken:
1. Call CAIRE, using one of the toll-free numbers, and request a Medical Technical Service Representative. State
the problem with the unit. If it is determined that the
problem cannot be solved by the distributor, a “Return
Authorization Number” will be assigned to the unit or
part(s). If a Purchase Order Number is to be referenced,
please give this number to the Customer Service
Representative at that time.
2. Carefully package the parts, or repack the unit in its original shipping container, precisely as shipped.
3. Write the Return Authorization Number on the top of the
shipping container.
4. Return the unit or parts by professional carrier to:
CAIRE, Inc.
3505 County Road 42 West
Burnsville, MN 55306-3803, USA
All equipment returned to CAIRE must be shipped
“prepaid.”
When the defective item(s) is received at CAIRE, it will
be serviced and returned to the distributor as soon as possible. A copy of the “Repair Cost Sheet” will be enclosed
giving a detailed listing of any maintenance performed.
Restocking Policy
If it becomes necessary to cancel an order with CAIRE
after the shipment has been received, use the following
“Restock Policy” procedure:
1. Notify the Customer Service Department at CAIRE
using one of the toll-free numbers. When contacting customer service personnel, it will be necessary to relay the
following information:
a. State the quantity and description of equipment to be
returned.
b. Give the Serial Number of each unit to be returned.
c. State the equipment purchase date.
2. A Return Authorization Number will be issued in the
name of the distributor by CAIRE for the equipment to
be returned. When the equipment is shipped to the factory, the Return Authorization Number must appear on
the packing slip.
3. All equipment must be returned “prepaid” to:
CAIRE, Inc.
3505 County Road 42 West
