15
Oxygen Cylinder Replacement

• Carefully tighten the yoke screw that holds the
  oxygen cylinder to the regulator.
• Tighten the Velcro strap on the O2 cylinder.
• Open the valve on the cylinder. If a leak is
  heard, repeat steps. If the cylinder continues to
  leak at the regulator, replace the stat-o-seal.
• Verify the whistle chirp. If cylinder leaks,
  tighten yoke screw and/or repeat steps.
• If yoke area is not protected unit must be stored
  with O2 bottles installed.

16
Pressure Gauge

• BioPak 240 is provided with a luminescent chest
  mounted pressure gauge.
• Gauge indicates service life only when O2
  cylinder is opened.
• Gauge will take up to 1 minute to read full
  pressure, due to flow restrictor.
• If severed gauge line occurs, flow restrictor
  will limit flow to 0.5 l/pm to allow safe egress.

17
Pressure Gauge

• Approximate pressure readings/safe working time
• 3000psig 4 hours.
• 2250psig 3 hours.
• 1500psig 2 hours.
• 750psig 1 hour.

18
Yoke

• Keep Yoke and Regulator area clean!!!!!
• Check the placement and condition of the STAT-O-
  SEAL.
• Pin Safety System.

19
Regulator Operation

• Factory adjusted regulator reduces the pressure
  from the O2 cylinder to approx. 265-275 psig.
• A flow function test is performed during the the
  turn-around process.
• The regulator is designed to fail in the open
  position.
• A failing regulator will be identified by an
  extremely high flow reading during the flow test.
• Users are not authorized to adjust, modify, or
  repair any parts of the regulator.

20
Yoke can always be stored with the rubber valve
cap when not in use.
21
Emergency Bypass Valve

• Emergency bypass valve is for emergency use only.
  
• The valve will add additional oxygen over and
  above the constant flow and demand valve. Valve
  rate is 80-100 l p/m
• Can be manually operated if the user is not
  receiving enough O2, allowing O2 to flow directly
  into the breathing chamber.
• To operate the bypass valve push button for 2
  seconds to add O2 to the breathing chamber.

22
Emergency Bypass Valve

• If use of the bypass is necessary the user is to
  evacuate the zone.
• Caution, excessive use of the emergency bypass
  will significantly decrease the duration of the
  BioPak.
• Use of the bypass will not clear a fogged
  face-piece.

23
Alarm Whistle

• The BioPak 240 is equipped with a audible 92db
  alarm whistle.
• The alarm will sound for 30-90 seconds, when
  cylinder pressure drops to 600-750 psig, or 20 -
  25 of the unit service life.
• Once alarm sounds user has approx. 1 hour of work
  time remaining.

24
Alarm Whistle

• When the Biopak 240 is turned on, the user should
  hear a chirp from the alarm to signal that the
  alarm is working properly. Alarm will also chirp
  after unit is turned off, with more than 750 psig
  remaining in O2 cylinder.

25
Cooling System

• The CO2 absorption process of the BioPak 240
  generates heat. This heat is removed by use of
  the gel tube. Cooling medium is non-toxic gelled
  water.
• Good for 4 hours at an ambient temp of 75 degrees
  F. NOT A CORE BODY COOLING SYSTEM.
• Place canister in standard freezer in a
  horizontal position for at least 8 hours if
  completely thawed.

CO2 Absorbent Canister

• In the absorbent canister, carbon dioxide (CO2)
  which is generated by the human body as a
  by-product of metabolism, is chemically removed
  from the breathing gas mixture. It is important
  to remove this out of the recycled breathing gas
  as it can be toxic over a period of time. The
  BioPak 240 uses LimePak to absorb CO2 by the
  following equation
• CO2 Ca(OH)2 CaCO3 H2O
• Or Carbon Dioxide Calcium Hydroxide Calcium
  Carbonate (limestone) water
• Or base acid salt

Carbon Dioxide Absorbent Filling

• Ensure the absorbent canister has been
  disinfected and the white disk is completely
  dried.
• Using LimePak fill the canister with absorbent to
  the fill line and outer ring line (up hill). Foam
  pad should be seen protruding from each hole in
  the stainless steel lid.
• If movement is felt heard when canister is
  lightly shaken, open and top off with more
  LimePak.

30
Carbon Dioxide Absorbent Canister Installation

• Ensure canister o-ring is in place and properly
  lubricated using DOW 111.
• Press canister into place in the breathing
  chamber, and replace stainless steel cover.
  Ensure all cover snaps are engaged properly, and
  label is properly orientated.

31
Absorbent Replacement

• The absorbent must be replaced
• Each time the unit has been used.
• If ambient air is introduced into the system for
  more than 1-hour.
• Units may be stored with filled absorbent
  canisters for up to 1 year provided the LimePak
  has not expired.

32
Units will be stored with the Stainless Steel Lid
turned 90, to identify empty canister
33
LimePak

• Shelf life of five years.
• Once opened the LimePak has a shelf-life of one
  year. The keg must be marked with the date
  opened.

38
Donning Procedures

• Place BioPak 240 with the harness up.
• Lengthen the shoulder straps so that the free
  ends extend two or three inches.
• Don the BioPak 240 like a suit coat.

39
Donning Procedures

• Bend at the waist and pull the shoulder straps
  tight onto your shoulders.
• You may loosen the shoulder straps to let the
  weight of the unit rest on your hips if desired.
• Tighten the waist belt.
• Connect the chest strap, do not over tighten
  because it will constrict breathing.
• Don facemask.

40
Donning Procedures

• Perform face mask check by blocking the
  inhalation port with your hand and inhaling.
  Mask should collapse on to your face. However,
  if mask leaks when you inhale with the inhalation
  port covered, adjust mask for better fit or check
  the exhalation check valve.

41
Donning Procedures

• Perform second face mask check by covering the
  exhalation port with your hand and exhaling. The
  facemask should push from your face by the
  pressure of your exhalation. If the mask is not
  pushed away, check the inhalation valve.
• Connect the facemask exhalation port (Red) first.

42
Donning Procedures

• Connect the inhalation side (Green) next. After
  the mask is donned and fully connected, open the
  oxygen cylinder valve fully counterclockwise and
  back ¼ turn.
• Verify chest-mounted pressure of 3000 PSIG. Note
  it is normal for the gauge to take up to a minute
  and a half to come up to full pressure due to the
  flow restrictor in the gauge line.

43
Emergency Operation

• The emergency bypass valve is used manually to
  supply oxygen to the breathing chamber in the
  event of failure of the demand valve or flow
  restrictor. Add additional bursts as required to
  maintain an adequate supply of breathing gas.
  Remember Oxygen is your friend. Unnecessary
  over-use of the Emergency Bypass will shorten
  your duration.

44
Emergency Operation

• Warning the bypass valve is intended for
  emergencies only and WILL NOT clear facemask
  fogging. WASTEFUL use of the bypass valve
  seriously reduces the duration of the unit.

45
Emergency Operation

• Emergency actions
• Equipment failure, such as blocked line.
• Try bypass, exit area.
• Severed pressure gauge.
• Exit area.
• Over-actuation of demand valve inside unit.
• Leak in system exit area. Bad facemask seal
  adjust facemask fit, and tighten hoses.
• User warning symptoms that require immediate
  attention
• Any feeling of nausea, dizziness or illness.
• Rapid pressure drop on chest mounted gauge.
• Any difficulty inhaling or exhaling.
• Smoke or other contaminants in the facemask.

46
Doffing the BioPak 240

• Warning most breathing apparatus malfunctions
  are directly traceable to careless handling after
  use. Many years of trouble-free operations are
  possible if reasonable care is given to the
  BioPak.
• Close the oxygen cylinder valve.
• Remove facemask by pushing forward on two lower
  release buckles and continue pushing forward and
  upward to lift the facemask over the head.
• Unfasten chest and waist straps and lean forward
  slightly at the waist.
• Loosen on shoulder strap, then allow the other
  shoulder strap to slide from the other shoulder
  while swinging the BioPak 240 around your front.
• Remove unit and set it down.

47
Turn-Around Maintenance

• Clean the mask and hose as normal using
  disinfectant.
• Place the unit on a flat surface and remove the
  upper housing.

48
Turn-Around Maintenance

• Slide the stainless steel lid snap latches away
  from the four retainer pins and remove the cover
  by pressing it up around the edges with your
  fingers and down with your thumbs on the
  breathing hose connections. Do not pry up on the
  lid with any objects. This will result in damage
  to the o-ring and breathing chamber.
• Lift the carbon dioxide absorbent canister from
  the BioPak 240 by pressing it up around the edges
  of the plastic rim with your fingers and down
  with your thumbs on the breathing chamber. Never
  attempt to open the canister while in the BioPak.

49
Turn-Around Maintenance

• Once removed from the BioPak remove the CO2
  stainless steel cover by sliding the snap latch
  away from the retainer set pin and lifting the
  cover.
• Remove the filter pad, empty the contents of the
  canister into the trash.
• Check the o-rings on the inside and outside
  perimeter of the breathing chamber for abrasions
  or cuts. Wipe the o-ring with a clean cloth to be
  sure they are clean and dry, then apply a thin
  film of DOW 111 lubricant to them.
• Wipe out any particles of carbon dioxide
  absorbent remaining in the canister well.

50
Washing and Disinfecting

• Prepare a disinfecting solution by adding 1
  packet of Portion Pak disinfectant agent per
  gallon of water.
• First clean the facemask, hoses, breathing
  chamber lid, and coolant canister gel tube
  with disinfectant. These parts may be immersed in
  the disinfectant, and then rinsed several times.

51
Washing and Disinfecting

• Pour 1 about quart of disinfecting solution
  through the short coolant canister hose. Capping
  the end of the tube with your hand, move the tube
  up and down to thoroughly coat the inside of the
  tube and its corrugations with disinfectant.
  Allow the disinfectant to flow into the breathing
  chamber.

52
Washing and Disinfecting

• Repeat previous step using the exhalation hose.
  Take care to protect the flow restrictor assembly
  from getting wet. Minerals in water can deposit
  on the restrictor and severely limit its flow.
  Use a finger cot to protect the top of the flow
  restrictor.
• Rotate the unit several times to agitate the
  solution in the breathing chamber, thoroughly
  coating it.

53
Washing and Disinfecting

• Pour the solution out of the breathing chamber.
• Repeat this process several times using fresh
  water rinse.
• Allow the unit to air dry or connect to dryer
  unit.
• Immerse the absorbent canister, absorbent sponge,
  and the canister lid in the disinfectant. Wait
  until all other components are sanitized so that
  any absorbent dust left in the canister does not
  get onto the other parts of the BioPak. Be sure
  to squeeze disinfectant through the sponge
  filter.
• Repeat this process several times using fresh
  water rinse.

54
Flow Test

• The oxygen constant flow is preset at the factory
  to 1.78 LPM. To check the flow
• Remove the outer case cover, the breathing
  chamber lid, and the CO2 absorbent canister. This
  exposes the flow restrictor which is on the top
  side of the demand valve assembly.
• Slip the BioPak flow meter over the flow
  restrictor.
• Using two wooden tongue depressors, hold the
  diaphragm away from the demand valve.
• Open the O2 cylinder valve and measure the flow.
  The acceptable flow range should be at a minimum
  of 1.6 l p/m and a maximum of 2.2 l p/m. If the
  unit is not within these operating limits RED tag
  the unit.
