MH EDS O 2 D2-2G 1 or 2 Person Electronic Digital Pulse-Demand Aviation Oxygen Delivery System INSTRUCTION MANUAL Thank you for purchasing the MH EDS O2D2- 2G Pulse-Demand Oxygen Controller. The EDS Pulse-Demand O2D2-2G is patented innovative oxygen control technology that... -
Page 2: Introduction
INTRODUCTION The patented MH EDS O2D2-2G (O2D2) is a one or two-user aviation oxygen delivery device. It is designed to deliver aviation oxygen in the most efficient, comfortable and convenient way possible. With its user-selectable settings, apnea alarm and small size, the O2D2 is the most portable and flexible electronic digital oxygen delivery system in the world. -
Page 3: Getting Started
GETTING STARTED The O2D2 is designed to be used with MH Cylinder Pressure Regulators. Pilots who intend to fly with the O2D2 are advised to familiarize themselves and their passenger with the system prior to using it. Four cannulas and two face masks are included with the O2D2 unit. -
Page 4: Inserting & Removing The Batteries
ON THE TUBING WITHOUT PUSHING IN THE COLLAR; IT WILL DAMAGE THE CONNECTOR. STORING THE MH EDS O2D2-2G When not being used, the O2D2 unit, oxygen tubes, cannulas, etc., should be disconnected from the oxygen supply and stored in a secure manner to ensure that dirt and debris do not become lodged in the inlet and outlet tubes. The supplied tote bags or a zip-top plastic bag is a good storage container. -
Page 5: Modes Of Operation
They also can be used with the MH cannula in situations where more oxygen may be required over the normal ‘N’ and ‘D’ settings. Since F-Mode settings are calibrated for use with the MH Alps face masks, only use the approved MH EDS or ALPS face mask. -
Page 6: Alarms And Alerts
18,000 feet, the aircraft should have a supplementary gauge, visible during flight by the pilot, to determine the cylinder oxygen pressure. You should also carry an EOS (Emergency Oxygen System) such as the MH Co-Pilot as a back-up safety feature in case the other system stops working. -
Page 7: Third Party Regulator
To use the MH EDS O2D2-2G with a third-party regulator or built-in oxygen system with a pressure higher than 20 psi, it is mandatory that you use the MH EDS IN-LINE REGULATOR (EDS ILR) to ensure correct flow pressure. The EDS-ILR goes between the third-party regulator or built-in system and the O2D2 to reduce the flow pressure to the appropriate level. -
Page 8: Troubleshooting
4. Check O2D2-2G outlet tubing for obstructions. • The O2D2-2G does not trigger: 1. Try using the Flared-Tip cannula included with the kit (MH part number 00EDS-1084-01) • When using the face mask, no oxygen pulse on inhalation: 1. Make sure the face mask is sealed against the skin. -
Page 9: Warranty
MH EDS O2D2-2G become defective within the warranty period return the EDS Unit with a description of what/why it is not functioning and we will repair or replace it, at our discretion, free of charge (you pay only shipping to MH). -
Page 10: Maintenance Questions
Portable Systems: ™ I have one of your portable MH-EDS PULSE DEMAND™ units. It seems to be operating just fine, should I send it in for any type of routine service or testing? Yes. Even though your pulse-demand unit will generally let you know if there is a problem and has been designed to be relatively maintenance free except for batteries, it should be sent in on a regular basis for performance inspection and service. -
Page 11: Auto Compensation
AUTO COMPENSATION INFORMATION EDS O2D2-2G Auto-compensation Altitude compensated breathing sensor Because absolute atmospheric pressure lessens as a function of altitude, breathing efforts assert less pressure upon breath- ing sensors to the point at which they may not properly detect breathing while at higher altitudes. Additionally, as the partial pressure of CO2 drops below a normalized point with altitude, one’s breathing efforts also diminish. -

Page 13: What Every Pilot Should Know About Oxygen
WHAT EVERY PILOT SHOULD KNOW ABOUT OXYGEN What Is Air? The air surrounding us is a mixture of gases consisting of 78% nitrogen and 21% oxygen. The remaining 1% is made up of argon, carbon dioxide, and traces of rare gases. What Is Oxygen? Under normal conditions, pure oxygen is a colorless, tasteless, odorless, non-combustible gas. - Page 14 How Should An Oxygen System Or Equipment Be Selected? Your MH Sales Engineer can help you at 800-468-8185. He or she can assist the pilot in selecting the system best suited to the specific airplane and the pilot’s special needs.
