adapter) and apply some Krytox (or, equivalent) lubricant.

G. Re-tape the DISS Oxygen connector, threaded portion, with sealant tape.

H. Re-install the DISS Oxygen Connector(s), screwing it closed, snugly, with the crescent

wrench.

2. Replacement of Rubber Bellows and Inspection of Exhalation Diaphragm Valve

A.Removal of Ventilator and Bellows Systems from Main Frame:

1. Turn anesthesia machine on the Vaporizer side of the machine.

2. Using a flat head screwdriver, remove the ventilator retaining screw.

3. Lay the machine down in its normal operating position.

4. Remove the two retaining knob/screws on the backside of the ventilator.

5. Disconnect the ventilator gas power tubing from the Ventilator GasPower Toggle Selector

Switch by pushing in on the tubing and simultaneously pushing inwards on the retainer

ring located on the tubing inlet receptacle.

6. Remove the ventilator/bellows system by pulling the assembly forward from the main

frame.

B. Removal of Rubber Bellows from Bellows Base, Inspection of Exhalation Valve

Diaphragm Valve and Installing New Bellows

1. Turn the clear plastic bellows canister cover counter-clockwise until the four plastic

retainer parts are clear of the black plastic retainers, (located on the top of the base of the

bellows assembly) and gently remove the clear plastic bellows canister cover, using an

upwards motion.

2. Remove the rubber bellows from the Bellows Base.

3. Each time the bellows assemblies are opened for inspection and cleaning, all visible

components must be carefully inspected and damaged parts must be replaced.

Bellows: The bellows is an elastomer material and deteriorates over time. Inspect the bellows

every six months if the system is in use. Inspect on the appropriate schedule (annual, to a

period of 3 years) if the system is in long term storage. Replace the bellows if there is any sign

of deterioration.

Exhalation Valve Diaphragm: The exhalation valve diaphragm valve is under the bellow and

can be removed by loosening the three thumbscrews.The valve seat is now visible.

WARNING: During inspection and cleaning (to remove contamination) of the valve seat and

diaphragm, use a soft cloth or brush. Abrasive materials may damage the seat and should not

be used.To preclude damage caused by the patient breathing into the valve, you should use

a bacterial filter in the expiratory breathing circuit.

Clean the seat (A) and the metal disk (B) attached to the base of the diaphragm valve

thoroughly and remove any contamination from the surfaces of both components.

NOTE: Any anesthesia breathing circuit filter may be used.

After cleaning, check the small O-Ring (C) located in the bellows base under the diaphragm

valve is in place.The system will not function if the O-Ring is not in place.

Refit the diaphragm valve assembly to the bellows base and reassemble the bellows

assembly.

4. Install new bellows to bellows base by placing the bottom bellows crease over the lip of

the bellows retainer. (See photos to the right.)

NOTE: Once the bellows is installed, turn the vent/bellows system upside down and observe

that the bellows fully expand and the folds are evenly opened. Re-adjust the bellows fold

where it is attached to the base and re-observe the expansion.

5. Using Krytox (or equivalent lubricant) place a small amount of the lubricant on the hard

plastic top ring of the bellows.

6. Using Krytox (or equivalent lubricant) place a small amount of the lubricant on the

bottom ring of the clear plastic bellows canister cover.

7. Re-install the clear plastic bellows canister cover by pushing the clear canister down

firmly over the bellows base, then turning the canister cover clockwise until the retainers

are completely covered by the retainer clips.

8. Re-install the ventilator/bellows system:

A. Place the ventilator/bellows system partially in place.

B. Re-install the ventilator power tubing into the Gas Selector Switch receptacle by pushing

the tubing firmly into the receptacle, then pulling the tubing backwards, firmly.

C. Push the ventilator/bellows system back into its normal position.

D. Re-install the two ventilator base knob-screws from the backside of the machine frame.

E. Turn the entire machine onto the vaporizer side of the system.

F. Re-install the ventilator retaining screw into the bottom of the ventilator through the

bottom of the machine frame.

3. Mandatory Replacement of Gas Manifold - High Pressure Color-Coded Tubing

Every five years or, at any necessary time, each of the 10 color-coded tubes that attaches

to/from the Gas Manifold should be replaced using the following procedure:

NOTE: The end of the color-coded tubing must be squarely cut; angled ends may not seat

properly.

A. Green (oxygen) and Yellow (Air) Tubing:The connectors from the Gas Manifold to each of

the following components are of the "push-to-insert-and-lock" type.

B. To dismount, push in on the outer ring and pull the tubing out.

C. To re-insert, push the end of the green tubing into the receptacle and then use a "pulling"

action to lock the tube in place.

Green Tubing Positions From Gas Manifold to:

A. Auxiliary O2 Flow Selector

B. O2 Pressure Gauge

C. O2 Flush Valve

D. O2 Flowmeter

E. O2 Position on Ventilator Gas Selector Toggle Switch

F. O2 Concentrator/High Pressure O2 Selector Toggle Switch

G. O2 Low Pressure Alarm

H. O2 Very Low Pressure / O2 Concentrator Pressure Alarm

Yellow Tubing Positions From Gas Manifold to:

A. Air Pressure Gauge

B. Air Position on the Ventilator Gas Selector Toggle Switch

C. Air Flowmeter

II. ROUTINE FUNCTIONAL TEST : The functional test may be done at annual intervals or at

any time that internal componenets have been replaced.

NOTE: The Routine and Annual Functional Test may be carried out at any interval.This test will

indicate any malfunction of the machine or its components and the Operator or Biomedical

Technician will be able to rectify any component that is not functioning properly.

Test Procedure:

1. Assemble and install all components needed for routine clinical use of the machine as

outlined in the Operators Manual, or the Laminated Set-Up Card.

2. Perform the Pre-Use Checklist and Laminated Set-Up Card (with photos) in sequence.This

Checklist is contained in the Operators Manual; the separate Pre-Use Checklist laminated

card and Set-Up Card are provided with each machine.

NOTE: If the machine passes the Pre-Use Checklist with zero problems, proceed to the

Calibration Guide in the next section.

CAUTION: If the machine does not pass the Pre-Use Checklist, correct the problem(s)

encountered, then proceed with the Calibration Guide.The Problem Solving Guide on page 13

of this Manual will assist the Operator in resolving possible common problem situations.

Calibration Guide:

CAUTION: The factory utilizes pressurized Air and Oxygen set at 50 PSI for all testing. It is

recommended that this pressure be used when possible. If higher or lower inlet pressures are

routinely utilized the ventilator may be re-calibrated at pressure inputs from 40 to 70 PSI.

Calibration Materials Required:

• Source gas of air or oxygen

• Appropriate hose set to connect to gas source

• Pre-Use Checklist

• Operating Ventilator

• Test Lung

• Patient Tubing Circuit

Procedure:

• Attach the patient circuit to the equipment and to the test lung.

• Set Minute Volume control knob to 10 LPM.

• Set Frequency conrol knob to 13 BPM.

• Ensure the bellows is fully inflated.

• Pressurize the ventilator and allow the system to cycle several times.

• Verify the following values on the test lung:

Minute Volume = 10 LPM

BPM = 13 per minute

Tidal Volume = 770 MI

NOTE: Values should be +/- 10% of settting.
