Do not alter, modify, or substitute any components without approval of the manufacturer. 6.
REMOVING THE AIR MASK may be recharged to 2216psig. (this applies to steel cylinders only). Steel cylinders without the plus (+) sign stamped after the latest test date must be removed from service. All other cylinders which are not 3AA type shall be filled to the designated service pressure only (as found on the DOT approval or stamping). For cylinders manufactured under a U.S. DOT exemption (i.e.
COLD WEATHER OPERATION SUGGESTED PROCEDURES FOR COLD WEATHER OPERATION Moisture can cause problems in SCBA if it freezes. However, moisture can cause freezing problems even if the surrounding air is above freezing. This is due to air flowing from the cylinder through the regulator drops from cylinder pressure to close to atmospheric pressure very quickly. As it does so it expands, causing the air and the regulator to become colder.

QUICK-FILL SYSTEM OPERATION QUICK-FILL SYSTEM OPERATION WARNING For transfilling operations using the Quick-Fill System, do not use any transfilling hose assembly or fittings other than those supplied by MSA specifically for the Quick-Fill System. Use of any other transfilling hose assembly and/or fitting can result in serious personal injury or death, and will void NIOSH approval. The Quick-Fill System may be used for transfill operations as described in this manual.
QUICK-FILL SYSTEM OPERATION FILLING INSTRUCTIONS FOR QUICK-FILL SYSTEM WARNING • • Do not connect a Quick-Fill System equipped Low Pressure SCBA to an unregulated secondary air source with a pressure greater than 2216psig. The Quick-Fill System equipped low pressure air mask is rated for a maximum working pressure of 2216psig. As an additional safety feature, the SCBA has a pressure relief valve which automatically vents at 2525psig.
QUICK-FILL SYSTEM OPERATION Note: If the secondary air source does not have a sufficient volume of air, the SCBA cylinder will not reach full service pressure. After approximately 45-60 seconds, pressure between the secondary air source and the SCBA cylinder will be equal. WARNING Do not transfill if the donor's audible alarm is ringing or NightFighter Heads-Up Display /ICM Unit Gauge are flashing.
QUICK-FILL SYSTEM OPERATION and close the cylinder valve. Air pressure in the regulator will drop, and the leak will slow down. c. Quickly replace the protective dust cap on the male fitting. This will form a redundant seal. d. Open the cylinder valve and return to fresh air immediately. 2. Preparing the Quick-Fill System for Storage: a. Press in on the center of the quick-disconnect dust cap to release any pressure in the Quick-Fill System hose. b. Roll up the hose and place it in its protective pouch.
URC ASSEMBLY OPERATION URC ASSEMBLY OPERATION WARNING • All NFPA 1981-2002 approved SCBA are equipped with a URC Assembly (Universal Rescue Connection) fitting. The URC Assembly is a male quick-fill inlet for use by Rapid Intervention Crews for emergency filling operations. The system also includes an automatically resetting pressure relief valve.
URC ASSEMBLY OPERATION PRECAUTIONS FOR USING URC ASSEMBLY 2. To attach the Quick-Fill System hose to the URC Assembly: a. Remove the rubber dust cap from the male inlet fitting on the URC Assembly. Be sure that the cylinder valve is fully opened. b. Remove the rubber dust cap from the female fitting on the Quick-Fill System hose. c. Push the female fitting on the male fitting until it snaps in place. Pull on the hose to be sure the fitting snapped into place.
URC ASSEMBLY OPERATION 1. If you are in fresh air and the dust cover will not stay on the URC Assembly because air is leaking, correct the condition before using the SCBA. 2. If you are filling the URC Assembly in a contaminated atmosphere and the dust cover will not stay on the URC Assembly because air is leaking: a. Immediately reconnect the Quick-Fill System hose to seal off the leak and return to fresh air. b. If you cannot reconnect the hose, reach behind and close the cylinder valve.
