Fixed Oxygen System. The System is designed to provide supplemental oxygen for the pilot and passengers. The System consists of a 77 cu ft bottle and a pressure regulator assembly located in the aft fuselage, a four (4) or five (5) place distribution manifold located in the headliner, a control panel located in the center console next to the flap switch, a filler port with a manual pressure gage located in the aft wall of the baggage compartment, related oxygen lines and System electrical lines, and up to five (5) flow devices consisting of either constant flow meters, or demand regulators, with either a cannula or face mask for each user. The FAA Approved flow devices consist only of Precise Flight A4 or A5 constant flowmeters, or the Precise Flight demand flow conserver. The A4 and A5 flowmeters are constant flowmeter options that are calibrated and adjustable for altitude to supply oxygen to either oxygen conserving cannulas, standard cannula, up to 18,000ft, or masks for altitudes up to the maximum operating altitude of the Cirrus SR22 /SR22T or 25,000ft whichever is less. The PreciseFlow® demand flow conservers are calibrated and adjusted by the user for altitude to supply oxygen to either dual lumen cannulas up to 18,000ft, or dual sensing masks for use to altitudes up to the maximum operating altitude for the Cirrus SR22/ SR22T or 25,000ft whichever is less.  Note  Facemasks covering the nose and mouth are required above 18,000ft per 14 CFR Part §23.1447. The cockpit control electrically actuates the regulator allowing oxygen flow into the aircraft cabin. The cockpit control will annunciate O2 REQ’D if the System is not selected ON and the aircraft is above approx. 12,000ft PA to alert the requirement of oxygen in the cabin. Once the oxygen is selected ON, the quantity display illuminates indicating the presence of oxygen in the cabin. System faults are indicated by the FAULT Annunciator. Steady fault indication signifies a problem with the aircraft wiring and will disable the System. When a steady fault indication is present, the System is disabled and will not reset until Cirrus Design Approved Oxygen Systems Section 9 SR22 Precise Flight, Inc. Supplements SR22T Fixed Oxygen System FAA Approval Date: _________________ Document No.: 102NMAN0001 Rev.: F Page 9 of 48 power is cycled to the controller. This can be done by cycling the OXYGEN / CABIN LTS circuit breaker, or by cycling aircraft power. Flashing LED FAULT indication specifies an oxygen pressure fault to the distribution manifold. The oxygen quantity display will flash red if the bottle pressure falls below 400 psig.  Note  When the System is first engaged, the FAULT light may briefly flash until proper pressure is sensed at the overhead distribution manifold. This is normal, as pressure may bleed off when not in use.  Note  In the event of an electrical failure on Main Bus 2, oxygen will remain on in the cabin. Aircraft electrical power is required ONLY to turn the System ON and OFF. The System is designed to remain ON during an electrical failure, but oxygen quantity indication will be lost. Disconnecting the lines from the manifold will prevent the free flow of oxygen in the cabin. Prior to flight, the pilot should turn System ON to ensure sufficient oxygen quantity (pressure) exists for the flight and for passenger requirements using the duration charts included in this Supplement. The System is selected ON at the oxygen control at pilot discretion to meet personal physiological or FAA flight rule requirements. The System requires the user(s) don an Oxymizer cannula, a standard cannula, or an oxygen mask for the constant flowmeters. All users will subsequently set the flowmeter ball or the altitude knob on the PreciseFlow® to the pressure altitude indicated on the primary flight display, or above that altitude to meet the pilot or passenger physiological requirements if additional oxygen is needed. The flow devices provide the means to distribute the appropriate amount of oxygen for the pressure altitude of flight and indicate the presence of flowing oxygen to the pilot and users. All flow devices must be checked periodically (recommended intervals of less than 10 min.) to ensure flow and correct settings, as well as the oxygen control panel quantity indication. All delivery systems must be properly set to the corresponding altitude with each change in pressure altitude. Cirrus Design Approved Oxygen Systems Section 9 SR22 Precise Flight, Inc.

Supplements SR22T Fixed Oxygen System FAA Approval Date: _________________ Document No.: 102NMAN0001 Rev.: F Page 19 of 48 1.3 – PreciseFlow® Oxygen Conservers (PFOC) The PreciseFlow® Oxygen Conserver is a Demand Regulator calibrated and adjustable for altitude to supply oxygen to Standard Dual Lumen Cannulas up to a maximum altitude of 18,000ft MSL, or Dual Supply PFOC Masks up to a maximum operating altitude of 25,000ft MSL, or the maximum operating altitude of the aircraft whichever is lower. The system requires the pilot to don either a Dual Lumen Cannula or a PFOC Mask first, then the pilot will open the Oxygen Valve, noting oxygen quantity, and subsequently set the Altitude Dial to the pressure altitude chosen for flight, or at a setting above the altitude chosen to meet the pilot physiological requirements. Additionally the PreciseFlow® Oxygen Conserver can be set to constant flow for additional oxygen when required.  Note  Facemasks covering the nose and mouth are required above 18,000ft MSL per 14 CFR Part §23.1447.  Note  PreciseFlow® with Inline Regulator must be used with the Cirrus SR22/SR22T built in system. Figure 11 - PreciseFlow® Oxygen Conserver Breathing Station Kit (with Dual Lumen Cannula and Standard Dual Supply Mask Shown) Cirrus Design Approved Oxygen Systems Section 9 SR22 Precise Flight, Inc. Supplements SR22T Fixed Oxygen System FAA Approval Date: _________________ Document No.: 102NMAN0001 Rev.: F Page 20 of 48 There are three major reasons for using the PreciseFlow® Oxygen Conserver on a general aviation aircraft. One is the conservation of oxygen, allowing smaller portable or fixed oxygen bottles to be used or to increase the duration of usable oxygen for a given volume. The second is that the manner of delivery for a demand conserver is physiologically better. Third being that interrupted flow is better for the user’s nasal passages. Conservation - Utilizing demand flow and interrupting the flow of oxygen can provide a potential savings of 3 fold over continuous flow systems. The three fold savings is derived from a standard breathing cycle with 1/3 of the cycle being inhalation and exhalation taking the remaining 2/3. The PreciseFlow conserver defaults to constant flow with rapid breathing (breathing over 22 breaths per minute) as hysteresis in the mechanical system defaults the unit to constant flow. Delivery – The ability to deliver a bolus of oxygen improves oxygen saturation by allowing the first air of the inhalation cycle to be more fully enriched with oxygen. It is this gas that participates in gas exchange in the lungs with the remainder of the breath providing the pressure to allow the gas to exchange across the lung surface into the blood. This bolus of oxygen can be felt and encourages the user to breath through the nose. Comfort – The ability to interrupt flow keeps the dry oxygen gas from flowing over the nasal passages continually. The lack of dry gas flow allows the nasal passages to remain moist. The comfort level encourages oxygen usage for people with sensitivity to nasal discomfort. The PreciseFlow® Oxygen Conserver provides the means to efficiently distribute the appropriate amount of oxygen for the pressure altitude of flight, and indicate the presence of flowing oxygen to the pilot or passengers. The PreciseFlow® Oxygen Conserver Flow Indicator and oxygen quantity gauge should be checked periodically at an interval of no more than every 10 min. The PreciseFlow® Oxygen Conserver should be set for each change in pressure altitude or for personal physiological requirements. This supplement is applicable when supplemental oxygen is required by the applicable operating rules, and provides mounting instructions. The different mode combinations for the PreciseFlow® Oxygen Conserver unit are shown in Figure 12 where the first picture shows a typical operation setting for flight between 16,000ft and 22,000ft. The unit is set to conserve using the Cirrus Design Approved Oxygen Systems Section 9 SR22 Precise Flight, Inc. Supplements SR22T Fixed Oxygen System FAA Approval Date: _________________ Document No.: 102NMAN0001 Rev.: F Page 21 of 48 mode select dial, and the altitude is set to ‘16K’. Instructions provided to the user state that the PreciseFlow® Oxygen Conserver should be adjusted to the next higher altitude from where flight is being conducted. Above 18,000 ft where a mask is required, constant flow is to be selected with a dual supply mask as indicated with a box around the altitudes on the altitude selection knob, and the ‘constant’ on the mode select knob. If physiological requirements differ for the user, the ‘constant’ mode, or a higher altitude setting may be selected at any altitude. The THP setting is calibrated to flow 4LPM of Oxygen. This far exceeds the minimum flow requirement of 2.3LPM at 25,000ft should additional oxygen be required by the user. The conserve mode process is accomplished by an internal flow control disk that controls the flow of oxygen and a valve system controlled on the inhalation and exhalation cycles of the user within the unit. This breath cycle is sensed through the use of a dual lumen cannula, or the dual port mask. A calibrated orifice controls the flow rate is set by the altitude knob at the end of the unit. Figure 12 – PreciseFlow® Oxygen Conserver – Mode Combinations  Caution  Use of cannulas recommended only for person who have demonstrated the ability to be properly oxygenated with these delivery devices. Precise Flight Inc. encourages the use of a pulse oximeter while using supplemental oxygen system as people’s physiological differences can alter oxygen saturations from person to person.

This cannula is unique in that it provides both oxygen delivery and sensing to the PreciseFlow® Oxygen Conserver. The sensing port is required to provide a pressure drop to the PreciseFlow® during inhalation, signaling the conserver to provide oxygen through the deliver line. Figure 14 - Dual Lumen Cannula First attach the Dual Lumen Cannula to the PreciseFlow® Oxygen Conserver, one tube connector to the Delivery side, and the other to the Sensing side as shown in Figure 15.

Please make sure you are wearing the cannula with the tab pointing down (found at the base of the nasal prongs - see Figure 16). Figure 16 - PreciseFlow Conserver Cannula Usage 2. Flow can be restricted if the small diameter tubes that lead to the nasal prongs on the cannula get pinched under a headset. The best solution is to put the cannula on over your headset so the tubes rest on the outside of the earpieces. 3. Adjust the PreciseFlow Oxygen Conserver to the desired altitude and breathe through the nose.  Note  Proper Oxygenation above 16,000 feet using the PreciseFlow Conserver and Dual Lumen cannula requires deliberate and consistent deep breathing through the nose.  Note  Cannulas are limited to a maximum altitude of 18,000ft MSL per 14 CFR Part §23.1447.

As you clean the equipment pay close attention to the condition of the lines and silicone moldings to ensure no tears or kinks have occurred. Carefully restore oxygen components. 8.2.1 – Flowmeter Anti-Static Periodic anti-static treatment may be required on the flow meter should the ball act ‘sticky’ or function erratically. This is caused by the handling of the flowmeter and a simple cleaning is required. The use of de-ionized water with a very mild oxygen and breathing safe detergent is needed. Remove the cannula or mask and add a few drops of this solution in the end of the tube and let it reach the tapered tube of the flowmeter. Then run clean oxygen through the flowmeter until dry. The flowmeter is then ready for use 8.3 – Oxygen Bottle Removal See FAA-Approved Instructions for Continued Airworthiness for the Precise Flight Oxygen System for oxygen bottle removal instructions.
