DESCRIPTION OF THE AIRPLANE AND ITS SYSTEMS 7.15 OXYGEN SYSTEM 7.15.1 GENERAL A four-place oxygen system provides the supplementary oxygen necessary for continuous flight at high altitude. An oxygen cylinder is located in the center section of the forward baggage compartment, in its own enclosed, vented compartment. A combined pressure regulator/shutoff valve attached to the cylinder automatically reduces pressure to the delivery pressure required for the operating altitude. The oxygen cylinder filler valve is located on the LH side of the oxygen compartment next to the cylinder in the forward baggage compartment. The 50 cubic feet (1.41 cubic meters) capacity oxygen cylinder may be filled to 1850 psi while installed in the airplane and has a pressure gauge located next to the filler valve to indicate the amount of oxygen in the cylinder. An identical gauge is located on the upper RH side of the instrument panel (above the circuit breaker panel). The oxygen supply shut-off control is located on the LH side below the instrument panel. It is cable connected to the oxygen regulator valve, controlling the oxygen system by pulling the green control knob out for “ON” and pushing the same knob in for system supply “OFF”. The system should be left “OFF” when not in use. Four (4) oxygen ports, two forward and two aft, are located in positions convenient to all four occupants. These ports are serviced directly from the oxygen cylinder. The oxygen ports are located (1 each) in the map pocket recess for the pilot and co- pilot. The passenger oxygen ports are located overhead in the “roll-over bar” next to the cabin speaker. The individual cannula or mask supply tubes are plug-in connected to each port and contain the individual flow adjustments (flow meter-needle valve) for each occupant. Note that these ports are serviced directly from the oxygen regulator valve. Continuous Flow Oxygen System DA 42 AFM with OÄM 42-102 Garmin GFC 700 Supplement S04 Page 9-S04-24 09-Mar-2021 Rev. 2 Doc. # 7.01.06-E It is the pilot’s responsibility to instruct each passenger in the use of this oxygen system prior to flight and to assure that there is adequate and comfortable supply of oxygen aboard for each occupant. The oxygen cylinder, when fully charged, contains 50 cubic feet (1.41 cubic meters) of aviator’s breathing oxygen under a pressure of 1850 psi at 21 °C (70 °F). Filling pressures will vary due to the ambient temperatures in the filling area and the rise of temperature resulting from the compression of the oxygen. Due to these factors merely filling the cylinder to 1850 psi will not result in a properly filled cylinder. Fill oxygen cylinders to the pressures indicated in the table shown below, based of the filling area’s ambient temperature. The oxygen system is limited to 1850 psi at 21°C (70 °F) ambient temperature. WARNING Oil, grease or other lubricants in contact with oxygen creates a serious hazard. Such contact must be avoided when handling oxygen equipment. Ambient Temperature °C (°F) Max. Filling Pressure [psi] Ambient Temperature °C (°F) Max.

Slide the loop adjustment collar (bola) down to enlarge the size of the loop: 2. With the back of the facepiece toward you, pick up the Oxysaver with one of the small flexible plastic tubes in each hand, as if putting on eyeglasses: DA 42 AFM with OÄM 42-102 Garmin GFC 700 Supplement S04 Continuous Flow Oxygen System Doc. # 7.01.06-E 10-Nov-2011 Rev. 1 Page 9-S04-27 3. Place the flexible plastic tubing over your ears (as if putting on glasses) and under your chin or pass the tubing over your ears and around the back of your head: 4. The facepiece should rest on you upper lip under you nose, with the oxygen delivering prongs extending well into and pointing towards the back of your nose. You may rotate these prongs for maximum comfort. 5. Slide the bola up toward your chin to hold the cannula snugly and comfortably against your face. 6. Screw the brass hose tip onto the manifold NOTE The use of each Oxysaver cannula system is to be logged by the hour and the system replaced with a new unit at 200 hours of use! Use the LOG delivered with each Oxysaver cannula. Continuous Flow Oxygen System DA 42 AFM with OÄM 42-102 Garmin GFC 700 Supplement S04 Page 9-S04-28 10-Nov-2011 Rev. 1 Doc. # 7.01.06-E c) Masks 1. Remove the rubber band from the reservoir bag and allow it to deploy. 2. Attach Aerox flowmeter to the oxygen hose of mask and then to the oxygen system. NOTE The reservoir bag must be in good condition and inflated before use! 3. Position the bottom of the mask as low as possible under the chin while positioning the narrow portion of the mask on the bridge of the nose. 4. Position the cradle above the ears so that it straddles the crown of the head. 5. Hook the lower headband straps below the ears and around the back of the neck. 6. Adjust the upper headband by pulling both straps at the same time. 7. Adjust the lower headband straps in the same manner. 8. Remove the mask to adjust the straps. 9. Do not over-tighten the straps. NOTE Return mask to Aerox for service 3 years from manufacture date. Manufacture date code is located on the re-breather bag.

Plug in the microphone plug in the applicable microphone jack (type: MSK-AEM only) d) Flowmeter installation/adjustment 1. Connect the flowmeter between the cannula /mask tube (outlet) and the delivery hose (inlet). NOTE When assembling the tube to the flowmeter, only push the tube as far as the second ferrule. 2. Connect the cannula/mask assembly to the assigned outlet manifold. 3. Hold the flowmeter in vertical position and turn the needle valve screw installed on the connector counterclockwise. Adjust flowrate to current altitude by using the correct flowmeter scale. NOTE For regular / “standard”- cannulas the “MASK” scale must be used.

NOTE When adjusted to the correct altitude the dispensing unit will deliver enough supplemental oxygen as required by “normal” people. Some people will require more oxygen. In that case adjust the flowmeter to a higher altitude. 4. Check flowmeter regularly to ensure adequate flow. 7.15.3 APPROVED OXYGEN The AEROX continuous oxygen system uses aviator’s breathing oxygen in accordance with MIL-PRF-27210 only. CAUTION Do not use oxygen with a lower purity grade than prescribed by MIL-PRF-27210. CAUTION The oxygen cylinder is limited to a pressure of 1850 psi at 21°C (70 °F) ambient temperature..
