IMPORTANT GENERAL INFORMATION SECTION ONE
a) General
The following details are to be seen as a guide only and are not intended to be a comprehensive
list of safety precautions.
i) Qualified persons
Persons servicing and repairing Pneupac ventilators and regulators must be adequately trained and
certified by the manufacturer for this task and must be fully conversant with the relevant contents of
the User's Manual supplied with the equipment. Engineers must perform service repair and testing of
equipment in line with both Health and Safety at Work regulations and their own employer’s
procedures and observe appropriate precautions necessary when handling pressurised gases.
This Maintenance Procedure should be read fully before commencing servicing and testing.
ii) Frequency Checking
Regular performance checking of the paraPAC ventilator must be carried out with equipment
calibrated to ensure accuracy under the flow patterns generated by the ventilator.
The user should determine the frequency of periodic checks dependent upon the intensity of use.
Normally this would be not more often than once every 6 months but at least once every 2 years.
iii) Oxygen Safety
WARNING: Oil, grease or combustible lubricants, other than those approved for oxygen
service, must never be allowed to come into contact with the parts of the ventilator,
oxygen regulator, cylinder, repair tools or repair surfaces used in the servicing of this
equipment. Particular care should be taken to avoid any trace of contamination around
the oxygen inlet and outlet ports of the ventilator. Oil or grease oxidise readily and in
the presence of oxygen will burn violently.
Regulator assemblies must not be immersed in liquid at any time.
iv) Note to Service Engineers
It is the responsibility of the customer to present the equipment in a fit condition for use and therefore
servicing (if this is not your responsibility). This should enable you to quickly assess the condition of
the equipment overall and any obvious damage.
v) MRI:
When the ventilator is being used/or likely to be used in an MR Environment, it is important
that only MR compatible spares or accessories are used. This must be checked as part of the on
site maintenance procedure.
vi) CE marking
The paraPAC ventilators described in this manual carry a CE mark to certify that they have been
manufactured to conform to the requirements of the European Medical Devices Directive 93/42/EEC.
To ensure that this equipment is maintained to the requirements of the Directive only accessories,
ancillaries and spares authorised by the manufacturer should be fitted. All such parts sold by Smiths
Medical have /CE incorporated in their order code. Parts that are not marked with /CE are only for
sale outside the countries bound by the Directive.

504-2033 Iss. 1j 4 April 2005
b) SAFETY INFORMATION FOR MEDICAL GAS CYLINDERS
1) The warnings on the previous page relating to the use of oxygen are particularly relevant to gas
cylinders and cylinder pressure regulators.
2) All personnel handling medical gas cylinders should have adequate knowledge of the
properties of the gas, precautions to be taken and the correct operation of the equipment.
3) Check the cylinder for the name of the gas and the colour code to ensure that the correct
cylinder is being used.
4) Before using a cylinder check it and its valve are in good condition. If there appears to be any
damage do not use it.
5) All cylinders are fitted with a colour-coded ring on the valve stem showing when it is due for
inspection or test. Check that the cylinder is within date. If not do not use it.
6) Completely remove the plastic seal from the valve. Open the valve momentarily to blow any
contamination out of the valve outlet. Ensure that the outlet is not directed towards any person.
7) Ensure that the connecting faces on the cylinder and the regulator or fitting are clean and free
from scoring or damage.
8) The regulator or fitting can now be attached, using only a reasonable amount of effort to
tighten the connection. Never use a hammer or lever.
9) Always open the cylinder slowly.
10) Always close the cylinder fully before disconnecting a cylinder and fit a cap or tape to the
cylinder valve outlet to keep it clean.

SECTION THREE
PROCEDURE FOR PERIODIC CHECKING OF
paraPAC P200/200D/220D
1. Record the serial number and model of the paraPAC and, where applicable, the serial
number located on the regulator assembly body.
Using the Pneupac datecode chart, check if the regulator assembly requires the
recommended 4 - 5 year complete disassembly service (refer also to Maintenance Manual
504-2008 for High Pressure Regulator Assembly).
2. Check Condition of Carry Case
i) Check case lids as they can tear on hinges due to mishandling.
ii) Check wooden stiffeners in side panels for rigidity.
iii) Check elastic and Velcro strapping for condition and security.
iv) Check case exterior for signs of splitting along the edges.
v) Check carry handles for security and tears.
vi) Check all zips for security and operation.
3. Check condition of Regulator Assembly
i) The warnings in Section One relating to the use of oxygen are particularly relevant to
gas cylinders and cylinder pressure regulators.
ii) Check that the cylinder valve is closed and the regulator assembly is de-pressurised.
iii) Disconnect the equipment probes from the regulator assembly.
iv) Release the T-handle slowly and remove the regulator assembly from cylinder.
v) Check that the T-handle is straight, undamaged and screws in and out freely.
vi) Check that the T-handle retaining circlip is in position.
vii) Check that the hexagonal nut on the pin-index yoke is tight.
viii) Ensure that the gas indexing pins are in position and are secure.
ix) From June 1997 a sintered filter has been fitted into the end of the pin-index yoke
nipple. Check that this filter (where fitted) is clean and not blocked. (The filter may be
replaced as described in Section 4 of the Maintenance Manual (504-2008) for High
Pressure Regulator Assembly).
x) Check the gas specific outlet connector and assembly for slackness and tighten if loose.
xi) Check that the relevant probe fits correctly into the connector.
xii) Check that the gauge is not loose and has not been bent in relation to the regulator.
xiii) Inspect the gauge for visible damage front and back. Ensure that the gauge indicator
needle is positively against the zero position stop.
xiv) Check that the gauge is fully protected by its rubber shroud and that the shroud is not
damaged.
xv) Check that the two rubber blow-out discs in the over-pressure relief ports are in place in
the regulator body.
xvi) Check that the secondary relief valve on the corner of the regulator block is not
damaged or blocked. If damage is evident the regulator must be changed.
xvii) If a Constant Flow Selector Head is fitted check the condition, looking for damage to
the head and/or the outlet connector.
xviii) Check that the head is securely fastened to the regulator manifold.
xix) Check that the Constant Flow Selector Head clickstop mechanism is effective.
xx) Check that any movement between the pin-index yoke and the regulator assembly
disappears when the assembly is attached to a cylinder.

504-2033 Iss. 1j 8 April 2005
4. Check condition of cylinder key
i) Replace if cracking is apparent.
ii) Check attachment cable is not frayed or damaged. Replace if necessary.
5. Check Regulator output
i) Fit a new seal (500-276) to the Regulator Assembly.
ii) Connect the pin-index yoke to a cylinder at least three quarters full.
iii) Connect the Test Unit to the outlet connector of the Regulator Assembly.
iv) Ensure that the Test Unit output is pointed away from the operator and that the flow/no-
flow switch is in the ‘Off’ (no-flow) position. Open the cylinder valve slowly allowing
gas into the regulator and the Test Unit. With no flow the pressure gauge on the Test
Unit will show the static output pressure of the regulator. Record this pressure which
should be between 50 - 80 psi (345-552 kPa) (50-70 psi (345-483kPa) for CE regulator
assemblies).
v) Slide the flow/no-flow switch to the ‘On’ (flow) position. This allows gas to flow
through the regulator and out of the Test Unit. The pressure gauge on the Test Unit
now shows the dynamic output pressure of the regulator. Record the result and switch
off the flow as soon as the reading is noted. This dynamic pressure will be lower than
the previous static pressure but should be no less than 45 psi (310 kPa).
vi) Re-check the static pressure reading and in particular check that it does not creep
continuously higher such that it eventually exceeds the upper allowed pressure of 80 psi
(552 kPa) (70 psi (483 kPa) for CE regulators). If the pressure continues to creep
upwards the main valve seat is leaking and the regulator needs corrective servicing.
vii) The above procedure should be repeated using a cylinder not more than a quarter full.
viii) Close the cylinder valve. The contents gauge should maintain a constant reading.
If the pressure decays at a visible rate, a leak is occurring and corrective servicing is
required.
ix) Vent the pressure by sliding the Test Unit switch to the ‘On’ position and then remove
the Test Unit.
x) Re-open the cylinder valve slowly, observe the contents gauge, then close the cylinder
valve. The gauge should maintain a constant reading. If the pressure decays at a
visible rate the outlet connector/s may be leaking and need corrective servicing.
xi) Where a Constant Flow Selector Head is fitted (500-A958) check the performance as
follows:
(a) Connect a calibrated flowmeter (e.g. 2-25 L/min; 500-82636) to the outlet
connector of the Flow Head.
(b) Using the table below check performance of the Flow Head across the range:
Set Flow L/min Actual flow L/min
2 1.8 – 2.2
5 4.5 – 5.5
10 9.5 – 10.5
15 14.5 – 15.5
xii) Replace the Regulator Assembly if any of the above checks fail or repair as
detailed in the High Pressure Regulator Assembly On-Site Routine Service
Procedure (504-2008).

504-2033 Iss 1j 9 April 2005
6. Check the Condition of the Input Hose
i) From 1st January 2002 pressure hoses are date coded and should be replaced after 5
years. Check the label on hose for replacement date.
ii) Check the hose for damage, cuts and abrasions.
iii) Check that there is no internal damage to the hose by feeling the rigidity of the hose
and looking for sloppiness.
iv) Ensure there is no delamination of the hose and no blisters or bubbles on the surface
(check again when the hose is pressurised).
v) Check union ends for signs of kinking and/or damage to hose or union.
vi) Replace hose if any of above is apparent.
7. Check the condition of the paraPAC
i) Check the ventilator looking for damage to the gas input and output fittings, the gauge
and gauge surround, the gas supply indicator, the control knobs, the case and the labels.
On the P220D check the Nebuliser outlet connection is not blocked and the
manufacturers plug is still attached to the ventilator casing. On ventilators fitted with
the EP option check that the manometer connection is secure and is not blocked.
ii) Check that the sintered filter in the input connector is clean and not obscured. Change
the input connector or filter if the filter is dirty. To change the filter, first remove the
connector and seal from the ventilator. The filter can be replaced by removing the O-
ring (W5520). The conical filter (W9151) should now be pushed from the connector.
Both O-ring and filter should be replaced. Refit the connector with a new sealing
washer (W5582).
iii) Check that the input and output connectors are secure. Tighten if necessary.
iv) Check that the control knobs move smoothly, are not loose on the spindles and do not
rub on the front panel. If the spindles are bent the knob may rub on the front panel on
one side only and the needle cartridge may be damaged.
v) Rotate each control knob to its extreme limits to verify that the knob has not moved on
the spindle.
a) The Frequency knob should align with both ends of the calibration marks, i.e. at
8 bpm and 40 bpm but should also engage the click stop position at 12 bpm.
b) The Tidal Volume knob should align with both ends of the coloured indicator
band.
c) The dot on the On/Off (CMV/Demand) switch should align with the calibration
marks and there should be no intermediate position.
d) The dot on the Air Mix/No Air Mix switch should align with both indicated
positions with no intermediate position. The knob should click into position at
the No Air Mix position and spring back to the Air Mix position when released
from the click position. (continued)

504-2033 Iss. 1j 10 April 2005
7. Check the condition of the paraPAC (continued)
v) e) The Variable Relief knob should align with the calibration marks at each end of
the scale.
vi) If the index mark on any knob side or end cap is misaligned it must be corrected before
further calibration checks are carried out.
vii) To relocate the Frequency and Tidal Volume knobs, remove the end cap from the knob.
viii) Using an appropriate knob collet spanner (e.g. 500-82073), release the knob from the
spindle.
a) For the Frequency knob, rotate the spindle until it engages the click-stop
position and set the indicator line on the knob at 12 bpm. Ensure that the knob
has a clearance of 0.5mm from the front panel and retighten. Check that the
knob aligns at the 8 bpm and 40 bpm positions respectively.
b) For the Tidal Volume knob rotate the spindle fully anticlockwise till it reaches
the stop and set the indicator line on the knob align with the end of the coloured
band. Ensure that the knob has a clearance of 0.5mm from the front panel and
retighten. Rotate the knob and check that it aligns with the opposite end of the
band.
ix) Refit the knob cap ensuring the line on the cap aligns with the line on the knob.
x) The On/Off (Demand/CMV-Demand), the Air Mix/No Air Mix switch and the
Variable relief switch knobs have a fixed position but the end cap can be relocated on
the front of the knob to give correct indication.
xi) If any of the caps on the above knobs have been removed for relocation or can be
rotated, relative to the knob, during normal operation they should be secured to the
knob with a very small drop of adhesive (DS354 C10/Loctite Prism 460).
xii) Check that the gauge surround is secure, the front panel label is secure and not
damaged (i.e. punctured) and the silence button is undamaged.
xiii) Check that the gauge is in the correct vertical position and has not rotated in the shroud.
xiv) Ensure that the battery cap is fitted in the correct orientation to suit the type of battery
installed (standard or MRI).
xv) Remove the existing battery and check when battery was last changed. If more than 12
months, insert a new battery of the correct type (ensure that if the ventilator is being
used, or likely to be used, in an MR environment battery part no W269-023 is used). If
service interval is less than 12 months, mark the battery, or service log for the
ventilator, with the date of replacement.
xvi) Replace any damaged labels.
xvii) Check that any accessories or spares added are MR Compatible including.
8. Check the Condition of the Patient Hose
i) Check the patient hose for damage, splits or small holes in the corrugated tube.
ii) If any defects are found replace the hose tube immediately.
iii) For EP Option circuits check that a complete circuit is available and has no defects.
iv) Check that the adaptor at the Patient Valve end of the circuit is undamaged, fits closely
onto the Patient Valve and the sensing line connecting spigot is not damaged.
v) Replace the filter (W7085) in the EP Option sensing line.

504-2033 Iss 1j 11 April 2005
9. Check the Condition of the Patient Valve
i) Check the Patient Valve assembly for cracks, splits and scoring to the connection faces.
ii) Disassemble the Patient Valve by unscrewing the two parts of the body and carefully
remove the valve element (lip membrane). Inspect the element by gently stretching,
looking for splits or tears. Replace if necessary.
iii) Carefully remove the annular disc surrounding the patient connector (200D only).
Inspect the element as ii) above. Replace if necessary.
iv) Reassemble the Patient Valve ensuring that the valve element is inserted the
correct way round and that the annular disc is correctly seated.
v) Recommend replacement if necessary.
10. Check the performance of the paraPAC P200/200D/220D (including alarm functions)
10.1 Check function of the Main Pneumatic Switch
i) Check that the Main Pneumatic switch is in the 'Off' or 'Demand' position.
ii) Without a gas supply connected to the ventilator module, select the 'On' or
'CMV/Demand' position.
iii) The gas supply indicator will stay red but the alarm LEDs will illuminate in sequence,
starting bottom left and rotating in a clockwise direction. After all 6 LEDs have lit a
Medium Priority alarm will sound and continue for 1 minute. If the ventilator is still
left switched on the alarm system will shut down.
iv) Connect the ventilator to an oxygen cylinder or supply (minimum requirement 60L/min
at 305 kPa ≈3 bar).
v) Select the ‘Off’ or ‘Demand’ position.
vi) Open the cylinder valve slowly. The gas supply indicator should now change from red
to white if the supply pressure is above the minimum specified.
vii) Select the 'On' or 'CMV Demand' position. The ventilator should now begin to cycle
and the alarm will go through the test sequence described in iii). The yellow Silence
LED (bottom right) will illuminate and no sound will be generated for 60 seconds.
After the 60 seconds silence the yellow Disconnect/Low pressure LED (top right) will
illuminate and continue to flash and a Medium Priority alarm will sound every 10
seconds. After a further 60 seconds, if no action is taken, the repeat rate will increase
progressively during the following 60 seconds to once every 5 seconds.
viii) Select the 'Off' or 'Demand' position and the ventilator should stop cycling. All the
alarm lights and audible signals should cease.
ix) If the ventilator continues to cycle after it has been switched off, then the Main
Pneumatic switch is leaking and must be repaired or replaced.
x) Remove the battery and insert a standard 1.5v AA size battery in its place. Select 'On'
or ‘CMV/Demand’. The alarms should show as in viii) above but the low battery light
should also flash.
xi) Select 'Off' or ‘Demand’. Refit the original battery.
xii) Select the 'On' or CMV/Demand' position.

504-2033 Iss. 1j 12 April 2005
10.2 Check function of Air Entrainment N.R.V.
i) Set the Tidal Volume to 200 mL, the Frequency control to 25 breaths per minute and
the Relief valve to maximum.
ii) Select 'No Air Mix'.
iii) With a Patient hose and patient valve connected completely occlude the outlet port of
the patient valve and note the movement of the needle on the Inflation Pressure Monitor
on the front of the ventilator. (This is particularly important for the EP Option as no
pressure will be indicated unless a complete EP circuit is connected.) The needle
should rapidly rise to the 8x100Pa (80 cmH2O) mark. The pneumatic audible alarm
should sound and the red High Pressure LED (top left) should start flashing after 1/10
second. The High Priority alarm will sound after 1 second and both of these electronic
alarms will continue for 10 seconds after the occlusion is removed
iv) Remove the occlusion.
v) Select 'Air Mix'.
vi) Completely occlude the outlet port and again note the movement of the needle on the
Inflation Pressure Monitor. The needle should this time rise rapidly at first then slower
until the 80 x100Pa (80 cmH2O) is reached but with one smooth action. The pneumatic
and electronic alarms should again operate as in 10.2 iii).
vii) If the needle rises jerkily to the 80 x100Pa (80 cmH2O) mark, there is a fault within the
air entrainment NRV.
10.3. Check the CMV/Demand Function (200D/220D only)
i) Connect a test mask to the outlet port of the patient valve preferably using a Heat &
Moisture Exchange Filter to provide a contamination barrier, or use a test circuit
complete.
ii) Set the Tidal Volume to 800 mL, the Frequency control to 12 breaths per minute.
iii) After giving the ventilator 4 to 5 breaths to settle down, demand a full single breath at
the end of the expiratory phase. The green Breathing Detect LED (bottom centre)
should illuminate briefly. There should be a short delay and then the ventilator should
deliver a second breath.
iv) Continue to demand full breaths on the ventilator at a rate faster than 12 BPM, which
should inhibit the automatic cycling. For each breath taken the Breathing Detect LED
should illuminate briefly.
v) Stop demanding breaths from the ventilator and it should begin to auto cycle after the
correct expiratory time has elapsed.
vi) Repeat the test but gradually reduce the size of each breath whilst maintaining the rate.
The ventilator should continue to inhibit until the breath taken is too small in flow or
short in time to inhibit. At this point the ventilator should restart auto cycling.
vii) Repeat the test again but this time using short ‘panting’ breaths. The ventilator should
ignore these and continue cycling.
viii) Select the 'Off' or 'Demand' position. Now demand a breath from the ventilator. The
Demand Valve should now supply oxygen to the Patient Valve. No LEDs will
illuminate.
ix) Close the cylinder or supply and continue to demand breaths. When the supply is
depleted, the gas supply indicator should change from white to red and the internal
spontaneous breathing valve should open. There should be a slight increase in
breathing resistance as air is drawn through the spontaneous breathing valve from
atmosphere.

504-2033 Iss 1j 13 April 2005
x) Remove the patient circuit, patient valve and mask. If an HMEF was not used, clean
the patient valve as instructed in the User’s Manual.
10.4 Check Frequency with No Air Mix
i) Connect a Pneupac backpressure device and ratePAC to the outlet port of the
ventilator module.
ii) Select the 'On' or 'CMV/Demand' position.
iii) Set a backpressure of 15 x100Pa (15 cmH2O) on the backpressure device. The green
Cycle Indicator LED (top centre) should now illuminate briefly for each cycle of the
ventilator as the pressure passes through 10 x100Pa (10 cmH2O). This should continue
through Checks 10.4 to 10.7.
iv) Select ‘No Air Mix’.
v) Using the table to set the controls, check the frequency of the ventilator across the
whole range ensuring that the backpressure is maintained at 15 x100Pa (15 cmH2O)
when VDel is changed.
