WARNING: Warnings tell about a condition that can cause injury to

the user or the patient.

CAUTION: Cautions tell about a condition that can cause damage to
the vaporiser and may result in injury to the user or the patient.

This manual and all its associated documentation must be studied thoroughly
before any attempt is made to install, operate or maintain any part of the
Apollo Tec 3 Style vaporiser. Failure to do so may result in user / patient
injury.

Special attention must be paid to each Warning and Caution as it appears in
the manual.

WARNINGS

The Apollo Tec 3 Style vaporisers are NOT MRI compatible.
Do NOT fill the Apollo Tec 3 Style vaporiser with any anaesthetic agent other

than the one specified on the front label. Any other agent used other than the
one specified can prove dangerous to the patient.

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 3 of 27

Do NOT overfill the Apollo Tec 3 Style vaporiser with any anaesthetic agent
above the maximum fill level as this may affect the performance of the device.
If it is over filled, then drain out the excess as described until the correct level
is regained before use.

There is no interlock fitted to the Apollo Tec 3 vaporiser therefore ONLY one
vaporiser to be connected at any one time to avoid cross contamination.

The Apollo Tec 3 Style vaporiser must NOT be used between zero and the
first calibration, if applicable.

Keep the Apollo Tec 3 Style vaporiser upright at ALL times.
Ensure ALL connections are gas tight before using the machine.
Before use, ALL connections must be checked for leaks and functional tests

MUST be performed as described in the anaesthetic machine user manual.
The dial control must be OPEN during all filling and draining operations.
Do NOT drain the anaesthetic agent into any other container other than a

correctly marked container for disposal. Anaesthetic agents must be treated
as pharmaceutical products and must never be drained into an open container
or reused in case of contamination. The liquid must always be disposed of as
a hazardous chemical.

After draining the Apollo Tec 3 Style vaporiser always ensure the drain plug is
fully tightened before replacing the screw cap (if applicable – dependant on
vaporiser configuration).

Do NOT turn the control dial on during filling, or attempt to fill the vaporiser
beyond the full mark.

When filled with anaesthetic agent the dial control must be set at “OFF” when
not in use and/or during transportation.

Anaesthetic agents are poisonous; great care must be taken to avoid the
spilling of an agent during filling or draining to prevent the risk of persistent
inhalation of trace concentrations from the atmosphere.

Expired anaesthetic gases must be removed from the operating theatre by an
appropriate anaesthetic gas scavenging system.

Periodically check the agent level. The Apollo Tec 3 Style vaporiser must be
filled at appropriate intervals. The vaporiser will function satisfactorily as long
as the anaesthetic agent is above the minimum level mark on the agent level
indicator.

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 4 of 27

Agent specific filling cannot be assured when bottles without collars are used.
Ensure the Apollo Tec 3 Style vaporiser is secured in an upright position for a

minimum of 10 minutes before it is connected to a patient or a breathing
system. Excess dosage may be delivered if the vaporiser is moved suddenly
during use.

The Apollo Tec 3 Style vaporiser MUST be connected so that the flow of the
gas to the patient is as indicated by the arrows on the device. The delivered
concentration will be incorrect if the flow is reversed.

The Apollo Tec 3 Style vaporiser has a relatively high resistance and must
NOT be incorporated in a breathing system downstream of the common gas
outlet.

Do NOT put water or any other solvent in the Apollo Tec 3 Style vaporiser.
Use the specified anaesthetic agent only.

Do NOT use the Apollo Tec 3 Style vaporiser if it has been dropped.
Do NOT carry the Apollo Tec 3 Style vaporiser by the control dial.
Do NOT immerse the Apollo Tec 3 Style vaporiser in any liquid including

water.
Do NOT sterilise the Apollo Tec 3 Style vaporiser.
Do NOT modify, tamper with or disassemble the Apollo Tec 3 Style vaporiser.

If the vaporiser is modified in any way there is danger of damaging the
vaporiser and the accuracy of graduation.

Do NOT use if changes in the performance of the device have been identified.

CAUTIONS

The Apollo Tec 3 Style vaporiser may be pressurised. Turn the screw cap
slowly when filling or draining vaporisers which are filled with screw cap fillers.

Turn the vaporiser dial control to “OFF” when not in use.
Halothane vaporisers must be periodically drained to prevent the build-up of

Thymol.

2. Description

2.1 General

The Apollo Tec 3 Style vaporiser is designed for “out of circuit” use in fresh
gas supply of a continuous flow techniques of inhalation anaesthesia. Each
vaporiser is agent specific and is clearly labelled with the anaesthetic agent
that it is designed for.

The Apollo Tec 3 Style vaporiser is temperature, flow and pressure
compensated so that its output remains relatively constant despite cooling
due to the vaporisation and variations in inlet flow.

The Apollo Tec 3 Style vaporiser provides accurate concentrations of
anaesthesia gases in the fresh gas supply; the concentration is specified
using the dial on vaporiser. The fresh gas supply must be between 0.5 and
10LPM.

The Apollo Plug on Block Tec 3 Style vaporiser is designed to be used on a
Selectatec Compatibility Block only.

Warning: If the vaporiser has been inverted, connect to a gas

scavenging system, set the dial to the top output and purge
the system with the carrier gas at 5LPM for 5 minutes.

Warning: improper use may result in patient injury.

Caution: Ensure the vaporiser is kept upright at all times.

Caution: Turn the vaporiser to the OFF position when not in

use.

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 7 of 27

2.2 The Dial Control

To set the desired concentration of anaesthetic agent, a single Dial Control
with a concentration scale calibrated in % of anaesthetic agent vapour per
volume (v/v) is used. This Dial Control incorporates a release button (see Fig
1 and 2) to help prevent accidental rotation of the dial from the “OFF” to the
“ON” position. A counter-clockwise rotation of the dial and simultaneous
depression of the release button is required to set the vaporiser to the on
position.

Figure 1 Apollo Tec 3 Style Vaporisers

3 Specifications

Apollo Tec 3 Style vaporisers are calibrated at 71.6°F (22°C) +/- 1°C using an
oxygen carrier gas at a flow of 3 litres/minute. The variation in output with
temperature, flowrate and duration of use is small, and the variation of output
when used with Intermittent Positive Pressure Ventilation is negligible.

The output of the vaporiser is affected by barometric pressure, and it may be
necessary to use a correction factor when analysing the output, especially at
high altitudes >1500 metres. The barometric pressure is not normally of
clinical significance

4 Installation

The Apollo Tec 3 Style vaporiser must always be mounted between the flow
meter unit and the patient breathing circuit, but upstream of any absorber or
humidifier. The vaporiser must be connected so that the flow of gas to the
patient is as indicated by the arrows on the device.

Check the integrity of the fittings to ensure that they are leak tight. If in doubt,
seek advice from the manufacturer of the equipment to which the vaporiser is
attached.

Ensure that the vaporiser is cleaned prior to first use. Remove the vaporiser
from its packaging, clean the exterior of the Tec 3 style vaporiser with a cloth

dampened with CE marked disinfectant as per the manufacturer’s

instructions.

Never allow cleaning agents to accumulate in the filler or gas inlet and outlet
ports or around the dial control.

4.1 General

Unless otherwise specified, all Apollo Tec 3 Style vaporisers are supplied as
standard with either 23mm Cagemount fitting inlet and outlet ports or a
Selectatec compatible ports.

Warning: Do not lift or support the vaporiser by the control dial, handle
with care at all times.

Warning: Do not use vaporiser if the liquid level is below the minimum
marker.

Warning: Allow the vaporiser to acclimatise to ambient temperature of
the location it is being used in, before the vaporiser is used.

20 March 2019 Page 11 of 27

4.2 Mounting the Vaporiser - Cagemount

Remove any dust caps before mounting. Cagemount fitted vaporisers have
the standard 23mm tapered ports: male (inlet) on the left and female (outlet)
on the right when viewed from the front, see Figure 1. There are two M6
threaded holes at the rear of the vaporiser, which are utilised to secure the
vaporiser onto the backbar of the anaesthesia machine using appropriate M6
studs and spacers.

(i) Lightly smear the tapers with oxygen safe grease such as Fomblin

UT18.

(ii) Push the gas tubing fully onto appropriate tapers and fully tighten

the vaporiser securing nuts.

Warning: Ensure all joints are gas-tight before using the machine,
perform a backbar function test as described in the anaesthetic
machine User Manual.

Warning: For cagemount models only one vaporiser to be connected at
any time.

4.3 Mounting the Vaporiser - Selectatec

Warning: Before fitting the vaporiser to the Selectatec manifold ensure
that the “O” rings on each manifold port valve are in good condition and
no foreign matter around the mating surface, this could cause leaks if
not checked correctly.

1. Remove any dust caps before mounting.

2. Check all the port valve ‘O’ rings, ensure they are free from damage and
intact, replace if necessary.

3. Ensure the vaporiser concentration control dial is in the ‘OFF’ position.

4. Ensure that the locking lever is in the unlocked position.

5. Carefully lower the vaporiser onto the manifold so that the vaporiser Plug
on Block port covers the two manifold port valves. Ensuring the ports are
correctly engaged with the valves.

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 12 of 27

Caution: Make sure that the locking lever is pushed all the way down
before turning it. The mechanism can be damaged if the locking lever is
turned before it is at the full extent of its vertical travel.

Warning: To help to ensure correct operation, do not use a vaporiser
which is visibly out of line on the manifold or which can be lifted off the
manifold when the locking lever is in the locked position.

6. Push the locking lever all the way down and turn the lever a quarter turn
clockwise, to lock the vaporiser onto the manifold.

4.4 Vaporiser Removal from the Manifold

1. Turn the dial to the ‘OFF’ position, if the vaporiser is not completely
turned ‘OFF’ then it cannot be released from the manifold.

2. Turn the locking lever a quarter of a turn anti-clockwise to the
unlocked position which will release the vaporiser from the
manifold.

3. Carefully lift the vaporiser up from the manifold, handling it from the
main body.

5 Operating Instructions

5.1 General

Warning: Do not fill the vaporiser until the dial is in the ‘OFF’

position, do not turn the dial whilst filling or attempt to over fill
the vaporiser above the line.

Warning: Do not fill vaporiser with any other agent other than
the agent specified vaporiser labelling. The vaporiser is
designed for labelled specific agents only and filling of any
other agent can prove to be dangerous to the patient.

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 13 of 27

Warning: Do not drain agent into any container other than a

properly labelled drug specific container.

The vaporiser must be filled and operated in an upright position. If the
vaporiser is not completely in the upright position and deviates slightly this will
not affect the output or the safety of the vaporiser.

Periodically ensure that the agent levels are checked and that the vaporiser is
re-filled at regular intervals. As long as the vaporiser is above the line

then the vaporiser will function in accordance with its specifications.

Not exceeding two weeks ensure that the vaporiser is drained into a drug
specific container, ideally when the agent is low on the agent level indicator.
This helps to remove accumulated contaminants and stabilisers and oxidised
impurities preserving the drug purity. Less frequent draining maybe allowed if
the anaesthetic agent does not contain additives or stabilising agents.

If using infrequently, Halothane vaporisers must be drained after use. When
Halothane decomposes it releases halides which can corrode metal
components, especially when in contact with water. Halothane also contains a
preservative, which is added by the manufacturer to inhibit decomposition,
which can cause vaporiser components to stick.

5.2 Turning the vaporiser “ON” and “OFF”

To turn the vaporiser “ON” depress the dial control release button and turn the
dial in a counter-clockwise direction. See Figure 1.

To increase the concentration, turn the dial counter clockwise passed the zero
mark to the required % concentration.

To reduce the concentration, turn the dial clockwise.

To avoid inadvertent delivery of small concentrations of agent, the dial control
must be turned to “OFF” when the vaporiser is not in use. Ensure the Release
Button returns to the locked position.

The vaporiser must not be used set between the Off and the Zero mark

5.3 Filling & Draining

5.3.1 Screw Cap Filler (filling procedure)

Warning: Before filling a screw cap filler vaporiser, slowly unscrew the
cap to allow any pressure to vent out slowly.

1. Ensure that the dial is OPEN. Remove the screw cap by turning it
counter clockwise.

2. Do not tip the vaporizer during the filling operation as this will result
in over or under filling

3. Remove the filler cap by turning it counter-clockwise,

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 15 of 27

Figure 2 Filling a screw cap filler vaporiser

4. Check that the agent to be used is the same as that specified on
the front of the vaporiser. In a ventilated area, pour the anaesthetic
agent slowly into the filler opening, observing the agent level
through the agent level indicator.

Caution: If the vaporiser was dry before filling, the level will decrease
slightly as the wick absorbs the agent.

5. When the agent level reaches the maximum level mark on the
agent level indicator the vaporiser is full. Replace the screw cap by
turning it clockwise. To prevent leakage, ensure that the screw cap
is fully tightened.

5.3.2 Screw Cap Filler (draining procedure)

Caution: Do not allow the drainage container to become completely full
during draining.

1. Remove the screw cap to reveal the drain plug.

2. Position a properly labelled container under the drain spout.

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 16 of 27

3. Invert the screw cap and use the slot in the top to unscrew the drain
plug. Do NOT fully remove the drain plug.

4. Open the dial slightly.

5. In a ventilated area, drain the anaesthetic agent into an
appropriately marked container and dispose of according to local
regulations.

6. Ensure the drain plug is fully tightened before replacing the screw
cap. Turn the dial to “OFF”.

Caution: If used infrequently, Halothane vaporisers shall be
drained after use.

5.3.3 Keyed Filler (filling procedure)

1. The keyed filler consists of 3 keyed elements

• The anaesthetic agent bottle collar.

• The bottle adapter.

• The filling / draining unit fitted to the vaporiser.

2. Remove the cap and seal from the anaesthetic bottle. Check that
the bottleneck is not chipped.

3. Fit the bottle collar of the bottle adapter to the bottleneck and screw
together until fully tightened. The bottle is then ready for filling.

Caution: Always hold the bottle below the bottle adaptor end

and below the vaporiser filler port, until the bottle adaptor is fixed into
position in the vaporiser.

Caution: If there is liquid in the air tube of the bottle adaptor,
remove the adaptor from the drug bottle and gently shake the adaptor a
few times to clear the tube.

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 17 of 27

Caution: The vaporiser must only be filled using the correct
agent specific adaptor, the adaptor will not fit the filler socket if
incorrect adaptor is used.

4. Ensure that the dial control OPEN for filling and draining. Turn the
top retaining screw on the filler unit slowly counter clockwise as the
vaporiser may be pressurised and withdraw the dummy filler plug.

5. Check that the agent to be used is the same as that specified on
the front of the vaporiser. Hold the bottle upright below the filler
socket and bend the adapter so that its end is horizontal and the
two holes in the adaptor are facing downwards. Insert the adaptor
into the filler socket.

6. After insertion, turn the top retaining screw clockwise to tighten it
and seal the bottle adaptor in the filler socket.

7. Raise the bottle above the level of the filler socket, avoiding kinking
the adaptor tube. A steady stream of bubbles should emerge from
the adaptor inner tube within two seconds. If this does not occur,
remove the bottle adaptor from the vaporiser. Then remove the
adaptor from the bottle. Carefully shake the adaptor two or three
times to clear the tube, then repeat instructions from stage 1.

8. When the vaporiser is filled to the maximum level mark in the
agent level indicator, lower the bottle below the level of the filler
socket and wait for 5 seconds to allow any agent in the adaptor to
drain back into the bottle. Unscrew the top retaining screw and
remove the adaptor from the filler. If there is any excess liquid agent
allow this to escape from the filler socket completely, insert and fully
tighten the dummy filler plug to prevent gas from escaping through
the filler.

9. The Tec 3 Style vaporiser is now ready for use.

Caution: If the vaporiser was dry before filling, the level will

decrease slightly as the wick absorbs the agent.

Figure 3 Filling a Keyed Filler Vaporiser

5.3.4 Keyed Filler (draining procedure)

Caution: Do not allow the drainage container to become

completely full during draining.

Caution: The vaporiser must only be drained using the correct
agent specific adaptor, the adaptor will not fit the filler socket if incorrect
adaptor is used.

1. Fit the bottle adaptor to an empty bottle. Insert the bottle adaptor
with its two holes facing upwards into the drain socket. Tighten the
bottom retaining screw.

2. Ensure that the dial is in the “OPEN” position. Ensure that the bottle
is below the level of the drain socket and the tube is not kinked. For
draining purposes (and to allow air to vent) unscrew the top
retaining screw slowly as the vaporiser may be pressurised and
remove the dummy filler plug from the filler socket.

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 19 of 27

3. Open the drain valve by turning it counter-clockwise. Allow the
vaporiser to drain.

4. Open the dial slightly.

5. If it is not possible to complete the draining process, close the drain
valve, loosen the bottom retaining screw, then remove the bottle
adaptor from the vaporiser. Remove the adaptor from the bottle.
Carefully shake the adaptor two or three times to clear the tube,
then reassemble and repeat instructions from stage 1.

6. When draining is complete, close the drain valve (clockwise),
loosen the bottom retaining screw and remove the bottle adaptor.
Replace the dummy filler plug into the top filler socket and fully
tighten the top retaining screw in a clockwise direction. Then turn
the dial to “OFF”.

Caution: If used infrequently, Halothane vaporisers shall be drained after
use.

Caution: If Halothane Vaporisers are used frequently, the vaporiser shall
be drained weekly and the liquid disposed of as a hazardous chemical.
Periodic draining of Halothane vaporisers is required because
Halothane contains thymol as a stabilizing agent which is less volatile
and will accumulate in the vaporiser, and can cause the output
concentration to decrease. The thymol residue may also have clinically
detrimental effects on the patient (see Rodenburg - Alila: Anaesthesia,
1984: 38: 581-583).

5.3.5 Quick Fill Filler (filling procedure)

Warning: Ensure that the drain screw; located on the bottom front of the
filler body; is correctly tightened to prevent loss of liquid agent.

1. Remove the protective cap from the anaesthetic agent bottle filler,

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual
20 March 2019 Page 20 of 27

ensure that the filler or bottle is not damaged before use.

2. Remove the filler cap by turning it counter-clockwise and insert the
bottle nozzle into the filler port. Make sure that the bottle filler
nozzle keys are aligned with the index slots in the filler port, as
illustrated in Fig. 4.

3. Press the agent bottle fully into the port of the filler block. Fill the
vaporiser until the maximum level mark is reached on the sight

level indicator. Pay attention to the air return bubbles flowing into
the agent bottle this is guidance that the liquid is flowing.

4. Once the vaporiser is full and the continuous stream of bubbles has
stopped, release the agent bottle from the filler port.

5. Remove the agent bottle and replace the filler cap and agent bottle
cap. Make sure the filler cap is tight to reduce any possible leaks.

Caution: If the vaporiser was dry before filling, the level will

decrease slightly as the wick absorbs the agent.

Caution: The vaporiser must be drained into a correctly

labelled container.

1. Remove the cap from the quick fill filler.

2. Remove the protective cap from an empty agent bottle. Place the
drain funnel onto the nozzle of the agent bottle, ensuring that the
index slots in the drain funnel are aligned with the agent bottle
nozzle keys. Then screw funnel onto agent bottle to secure.

3. Insert the drain funnel into the keyed drain slot; which is located
underneath the quick fill filler block.

4. Unscrew the drain valve which will allow the vaporiser to start
draining, drain until empty. Open the dial slightly.

5. Once draining is complete tighten the drain valve to reduce the
potential of a leak.

6 Checking the Calibration

The performance of the Apollo Tec 3 Style vaporisers, which are in clinical
use, is monitored by observing patient signs and consumption of anaesthetic
agent. The vaporiser is to be used with halogenated anaesthetic agent
monitoring equipment complying with ISO/IEC 80601-2-55.

Some users may, however, wish to employ analysers to determine whether
any abnormalities of performance have developed. For field checking of the
state of calibration, many techniques and analysers are available. Norvap
International do not recommend any one technique or analyser, but account
must be taken of errors of use and calibration of analysers. Ensure that the
appropriate carrier gas is used. The reliability of both the vaporiser and the
analysis system must be realistically considered.

If user requires that calibration verification is carried out on a vaporiser, to
determine whether any abnormalities of performance have developed the
following points must be considered:

1. The test method must be so designed that it follows closely the
clinical conditions of use.

2. The sampling technique is fully respective of the vaporiser output
and that it ensures that the absorption of agent by connecting
tubing is negligible.

3. If a number of vaporisers are being tested together and a consistent
error is seen, it is very unlikely that it is due to a fault with the
vaporiser. The apparent error probably lies in the test method
employed.

4. Reproducibility and consistency within the analytical technique must
be used.

5. Considerations into the effects of the carrier gas composition.

6. If obscure results are obtained from what is expected the accuracy
of the test equipment and/or test technique must be questioned and
verified.

7. Considerations of the effects of altitude and ambient temperature
must be allowed for, the readings and output can vary under

Doc. No. 157 Issue 1.0 Draft Apollo Operations Manual

different conditions.

8. Residual vapour will always stay in an anaesthetic machine from
previous use, therefore don’t be alarmed if an analyser detects
small concentrations of agent for a short time at the machine outlet
after the gas flow is turned on but the vaporiser is off.

9. If a selectatec fitting is being used and the readings are low, a cross
leak or leak to atmosphere should be considered from the mounting
system over the vaporiser.

7 Maintenance

Warning: Do not disassemble, modify or tamper with the

vaporiser. This can cause damage to the product and will alter the
accuracy of the performance.

Tec 3 Style vaporiser in a safe working condition.

7.1 Schedule

Biweekly when the agent level is low, drain the vaporiser into a correctly
labelled container and discard of the agent according to local regulations. If
the anaesthetic agent does not contain additives or stabilising agents then the
latter sentence can be less frequent, however the procedure must be done
annually.

one (1) year including calibration annually at a Norvap International
authorised Service Centre.
