III Equipment Description
Spirit 300, 600 & 1200

Figure 1: Spirit Unit

CAIRE, Inc.’s Spirit units serve as the portable components of the
CAIRE Reservoir/Spirit supplementary oxygen system. Enclosed
in a durable leather-look case, Spirits incorporate a stainless steel
cryogenic container with the valves, plumbing, and associatedhardware required to deliver gaseous oxygen to the patient at nearambient temperature.

3. Case – The case is made of a durable leather-look material which houses and protects the cryogenic container, thebreathing circuit, and the oxygen conserving device (OCD).

The Spirit is comprised of six major assemblies. Grouped according to function, they are:

5. Filling Circuit – The filling circuit consists of a quick disconnect device (either side fill or top fill) and associated plumbing, allowing the Spirit unit to be easily filled from sources
with a variety of connectors.

1. Cryogenic Container ­– This assembly is a double-walled,
vacuum insulated dewar for storing liquid oxygen at approximately -183° Celsius.
2. Breathing Circuit – This circuit consists of the manifold
assembly and a breathing coil. It utilizes liquid oxygen fromthe cryogenic container and warms it to near ambient temperature, so oxygen gas can be delivered to the patient.

4. Spring Scale – The spring scale uses a mechanical scale to display the liquid oxygen contents based on the weight of the unit.

6. Oxygen Conserving Device – This assembly uses a pressuretransducer to detect negative pressure created when a patient
inhales. A set volume of oxygen gas is then delivered to thepatient cannula tube via an electronically controlled valve.
NOTE: The oxygen conserving device (OCD) is unique to
CAIRE, Inc. with US Patent No. 6,910,­482.

V Safety

These hazards require certain safety precautions to be taken whenworking with or around gaseous and/or liquid oxygen:
1. Never permit combustible substances such as greases, oils,
solvents, or other compounds not oxygen compatible tocontact any component of the unit exposed to higher-thanatmospheric concentrations of gaseous or liquid oxygen. This
especially applies to tubing, fittings, and valves.
2. Keep oxygen equipment away from open flames or electricalappliances such as heaters, stoves, toasters, and other devices
with heating elements.
3. Never permit smoking in an area where oxygen equipment isrepaired, filled, or used.
4. Always wear goggles, a face shield, and insulated gloves whenworking with or around liquid oxygen.
While CAIRE, Inc. equipment is designed and built to the mostrigid standards, no piece of mechanical equipment can ever bemade 100% foolproof. Strict compliance with proper safety practices is necessary when using any Spirit unit. We recommend thatour distributors emphasize safety and safe handling practices totheir employees and customers. While safety features have been
designed into the unit and safe operations are anticipated, it isnecessary that all distributor personnel carefully read and fully
understand WARNINGS, CAUTIONS, and NOTES throughout
the manual. Periodic review of this information is recommended.

Spirit 300, 600 & 1200 Technical Service Manual • 11805120 L

Spirit 300, 600 & 1200

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 burnin air, burn at a faster rate and at a higher temperature in an oxygen enriched atmosphere. Other materials that do not burn in air
will burn as oxygen concentration increases. Additionally, many
greases and 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 pale blue in color.
At an operating pressure of 1,4 bar (20 psig), the temperature ofliquid oxygen is about -173°C (-280° F). Skin exposed to such a
low temperature can become severely frostbitten.

VI Theory of Operation
Filling (Figure 2)
1. MethodOCD

The Spirit is a portable unit designed to be filled by the patientfrom a CAIRE-manufactured reservoir.
LiquidGas
Vent Valve

Fill Connection
(QDV)
Gas

The unit is filled by coupling the quick disconnect valve of theSpirit with the quick disconnect valve on the Reservoir andopening the vent valve on the Spirit. A pressure differential
causes liquid oxygen to flow up the Reservoir fill tube, throughthe coupled quick connectors, and into the inner vessel of theSpirit.

Spirit 300, 600 & 1200

Figure 2: Filling

There will be some oxygen vaporized during filling. This gas
is discharged through the vent valve. The unit can be considered full when liquid oxygen is expelled from the vent valve.
Closing the vent valve and separating the units terminates thefill process.
2. Saturation Pressure
Liquid oxygen saturation pressure can seriously affect theoverall efficiency and operation of a Spirit unit.
Figure 3: Operation Pressure Above 20 PSIG

Gas toPatient
OCD

Economizer(Open)

Warming
Coils

a. If the saturation pressure of the liquid in the fill source isgreater than 30 psig (2,1 bar), high filling losses and/or frozen relief valves may result.
b. If the saturation pressure of the liquid in the fill source islower than 18 psig (1,2 bar), below tolerance flow rates may
result.
These problems can be prevented by always ensuring theReservoir is properly filled according to its respective service
manual.
Oxygen Withdrawal (Figures 3, 4)

Gas

With oxygen in the unit, and the vent valve closed, the pressurein the inner vessel will remain at or near the primary relief valvepressure of 25 psig (1,7 bar).
In the Spirit, as in all vacuum-insulated cryogenic containers,
some liquid (oxygen in this case) is always evaporating into agas. The rate of generation of this gas (called head gas) is called
the normal evaporation rate (NER). When the flow selection
knob is in the off position, this gas will build up pressure until
it is released between 21.9 psig (1,5 bar) and 24.2 psig (1,7 bar)through the primary relief valve.
When the flow selection knob is at any setting other than off, andthe economizer valve is open (pressure above 20 psig [1,4 bar]),gaseous oxygen is forced from the head space in the inner vessel,through the economizer valve, to the OCD. This process conSpirit 300, 600 & 1200 Technical Service Manual • 11805120 L

7 12

VI Theory of Operation
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 (1,4 bar), the economizer
valve closes. This causes liquid oxygen to flow up the withdraw
tube and through the warming coil where it expands and warms
into gas.
The gas then flows through the economizer regulator body to the
OCD assembly where its flow is metered to the patient according
to the flow selection knob setting and patient demand.
As the pressure in the container increases over 20 psig (1,4 bar),the economizer valve opens and the cycle repeats, maintaining thecorrect gaseous oxygen flow to the patient.

The OCD is powered by 2 C-cell alkaline batteries. When battery
voltage is low, the LED indicator will blink red with every triggered pulse. The batteries should be replaced with new ones when
this happens. In the event of OCD malfunction, the flow selection
knob can be turned to the “CF” position. This setting bypasses allelectronics and delivers a continuous flow of 2 LPM to the patient.
CAUTION: For proper OCD function, a standard cannula should
be used. Its length should be less than 25 ft. (7,6 m) and it should
be designed for 6 LPM or greater continuous flow.
Liquid Level Measurement

LiquidOxygen Delivery – OCD (Figure 5)
All Spirits are equipped with electronic Oxygen Conserving
Devices (OCD). The OCD pressure transducer detects the negative pressure generated when the patient begins to inhale. Basedon the flow selection knob position, a solenoid valve is open fora predetermined length of time, dispensing a controlled volumeof oxygen gas to the patient. An LED indicator blinks green witheach triggered pulse.

Spirit units are equipped with spring scales for liquid level measurement. This system measures the level of liquid
oxygen inside the unit using a mechanical spring.
The spring scale display is calibrated to read empty
when an empty unit issuspended by its ring. As
liquid oxygen is transferred into the portable,
the weight increases andthe spring scale reflects
the increase. Calibration
can only be performed
while the unit is empty.

IX Routine Maintenance (Schedule A, 30-Month)

Schedule A – 30-Month
A. Introduction
Routine maintenance is a series of steps used to assure that equipment is functioning properly.
1. If a unit fails a given test, one of two things may be done.
a. Refer to Troubleshooting/Repair (Section X) of this manual.
b. Return unit to CAIRE, Inc. for repair.
2. Schedule A – Maximum of 30 Months between routine
main-tenance testing. Unit should be tested when a problem
is sus-pected.
B. Procedure
Follow the steps in order listed. If the unit fails any step, refer toTroubleshooting/Repair (Section X) of this manual.
1. Visual Inspection:
a. Look for damaged or missing parts.
b. Dry condensation pad for Spirit 1200. Replace if soiled.
2. Fill Unit:
a. Fill unit full of LOX.
b. Check for audible or visual leaks in QDV and vent valve.
c. Verify that spring scale reads full.

3. Check Efficiency of Unit:
a. Allow unit to sit after fill for 10–15 minutes.
b. Inspect bottle for cold sweaty condition and for excessive
venting from relief valve (some venting is normal).
c. If either condition is observed, conduct NER test (see RP26
in this manual).
4. Flow Test (Table 1):
a. Set flow selection knob to “CF”, run for at least 20 minutes.
b. Check all flow settings with the chart below (RP22)andcheck pressure is within a range of 18–22 psig (1,2–1,5 bar).

Spirit 300, 600 & 1200

There are two schedules for routine maintenance which the homehealth care distributor may follow. These schedules allow the distributor maximum flexibility while assuring that equipment is
operating properly.
CAIRE, Inc. recommends returning the unit to a CAIRE service
facility every 10 years for vacuum check and re-evacuation
if necessary.

IX Routine Maintenance (Schedule B, Continuous)
A. Introduction
Continuous maintenance is a set of tests and inspections performed consistently to ensure equipment is functioning properly.
It can be done with equipment in service by drivers or other personnel.
1. If a unit fails a given test, it should be taken out of service andsent to the Repair Center/Department for further inspection.
2. Schedule B – Checks are made when the driver visits patients
and when equipment is transferred between patients.
B. Procedure
These inspections are to be performed by driver or other personnel
when Spirit is in use by the patient (LOX in the unit). This procedure must be performed at least once per year.
1. Visual Inspection:a. Case not damaged or dirty. Flow control knob turns easily
with firm detent feel.
b. Condensation pad on Spirit 1200 is not soaking wet or
excessively dirty.
c. QDV pin not bent (male rotary QDVs).
2. Verify that scale reads correct liquid level.
3. Check CF flow rate. Erie liter meter (± 0.25 LPM) can be used.

4. Flow Test (Table 2):
a. Set flow control knob to “CF”, run for at least 20 minutes.
b. Check all flow settings with chart below (RP22) and checkpressure is within a range of 18-22 psig (1,2–1,5 bar).

X Repair Procedures
The following procedures have been carefully prepared to allow
proper removal and replacement of defective components andshould 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 case assembly components.
WARNING: The worker’s hands, tools, and clothing should befree of all oils and greases.

CAUTION: When replacing components, make sure the new partis oriented exactly the same as the original part prior to installation.
CAUTION: Some components require a specific amount of torquewhen assembling. Follow torque requirements where specified.
NOTE: All replacement parts that come in contact with LOX
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 fromdust, soot, and other contaminants as possible.

WARNING: Parts that are welded in place must not be replacedin 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.

NOTE: When replacing components with pipe/tapered threads,
use Teflon® tape. Apply Teflon® tape as a sealant to threads nearend of component, avoiding first thread..

WARNING: The manufacturers of fluorolubricant warn users not
to allow fluorolubricant to contaminate tobacco products. Wash
fluorolubricant from hands before smoking.

NOTE: When assembling new compression fittings, tighten 3/16”
tube nuts five flats after finger tight, and 1/4” tube nuts eight flats
after finger tight. When reassembling previously used compression fittings, tighten nuts one to two flats after finger tight.
