18. A good facepiece seal is important to achieving full protection and proper SCBA duration.
19. Users should conform to MSHA/NIOSH guidelines concerning facial hair and the use of facemasks.
20. Replace the battery when the low battery alarm has activated, after 200 hours of use or every 6 months whichever comes first.
21. The connectors of the monitoring device may only be connected to a Biomarine BioPak 240R breathing Apparatus oxygen regulator, manifold block and breathing chamber.
22. The fiber optic cable may only be connected to the BioPak 240R remote gauge assembly.
23. Turn-Around maintenance procedures should be performed as soon as possible after each use.
24. It is acceptable to leave the oxygen cylinder in place until after washing and disinfecting has been completed.
25. Immediately after completion of BioPak use, remove the used CO2 scrubber canisters.
26. DO NOT submerge the Alarm Module during turn-around maintenance.
27. Do not allow any fluids to contact the input port of the pressure regulator.
28. Use only cleaners and disinfectants that are approved by Biomarine.
29. If Cleaning is not immediately possible after each use, at a minimum remove and discard the CO2 scrubber and moisture pad.
30. Remove the oxygen cylinder making sure the seal washer or outlet tube O-ring remains in place and install the regulator cover.
31. Thoroughly rinse all components in clean water to remove all disinfectant solution.
32. Chronic Obstructive Pulmonary Disease could limit or prevent the use of the BioPak 240 Revolution.
33. Place freeze forms onto a level surface in a freezer for a minimum of 8-hour period at a temperature of 10 degrees F or less.
34. If the optional magnetic wiper is utilized soak both chamois surfaces of the wiper pieces with water.
35. The manual(s) are the minimum recommended procedures for maintaining the BioPak 240R.
36. Failure to follow the minimum procedures presented in the manual(s) may violate government or agency approvals as well as void the manufacturer’s warranty.
37. To prevent mold growth, remove the moisture control foam pads after each use.
38. Do not pre-pack any BioPak that will be stored at temperatures at or below 32 degrees F.
39. Pre-packed carbon dioxide scrubbers may only be stored in the apparatus for a maximum period of 1-year.
40. Record the Carbon Dioxide scrubber serial number and use by date on to the maintenance tag or affix the scrubber label to back of tag.
41. Moisture control sponges must be installed dry when pre-packing the BioPak.
42. Apparatus that are pre-packed with the carbon dioxide scrubber shall be stored within the specific storage temperature and humidity levels and must be sealed air-tight in the apparatus.
43. Failure to install the moisture pad will result in scrubber flooding and cause elevated carbon dioxide levels in the inhalation gas.
44. Users are not permitted to mix versions of the Orbsorb within a BioPak.
45. Install two carbon dioxide scrubber canisters into the breathing chamber making sure that they are properly aligned and fully seated.
46. The alarm system battery shall be replaced after 200-hours of use, every 6-months or after the alarm system low battery alarm flashes with corresponding horn sounding.
47. The oxygen cylinder must be fully charged to above 1500 psi to perform a high-pressure leak test.
48. Use caution when installing the flow restrictor to ensure that the O-ring does not roll out of its gland.
49. The Cylinder should be inspected regularly for signs of damage to the outer wrapping.
50. The Turn-Around Maintenance Tag should be attached to the apparatus in a prominent location to show completion of all maintenance steps.
51. In addition to normal Turn-Around Maintenance, the SCBA shall be visually inspected, and pressure tested on a monthly basis if the apparatus is being used at least once a month or is placed in long term storage.
