2 Table of ontents PR System Description & Operation 1 asic PR omponents & Suggested Installation Layouts 2-5 Mechanical & Pneumatic Technical Information 6 on ongratulations on choosing the Mountain High PR (Pneumatically ontrolled Regulator) system. The PR system is a completely integrated, pneumatic powered oxygen regulator, designed to provide you with unmatched control, safety, comfort, and convenience at an affordable price. The design intent of the PR allows it to be used with any off-the-shelf G-540 cylinder valve, providing the ability to remove the cylinder for refilling purposes. If removing the cylinder is not convenient, a 4-SE high pressure access port is provided on the back of the PR to allow for an installation of a remote fill port and/or a remote pressure gauge, thus providing you with a variety of options for your installation application needs. (see pages 3 and on for diagrams of installation suggestions). The PR is not intended to be used as the main high pressure shut off, rather it is for giving the customer ease of use during flights and options for cylinder installation location. The valve of the cylinder should be turned off during times of aircraft storage as to mitigate any oxygen system drainage. It is not necessary to close the cylinder valve during refueling, lunch stops, leg stretches, etc. The 1/8" O.D. pneumatic lines that connect the remote ON/OFF toggle switch to the PR are flow restricted to a minute 1/64 liter-per-minute to prevent against the low pressure oxygen contributing to a shut-off event emergency. The PR is intended to be use with any G-540 cylinder valve with a service pressure range of 500 psig. to 2400 psig. (nominal 1850 psig.). The functioning high pressure inlet range is 3,000 psig MX. Operating past this inlet pressure will not cause damage, rather it may cause the PR to be forced open, causing a "safety venting" through the low pressure outlet.

The control valve (red) is moved up (open) and down (off) pneumatically via the external control switch.

3 The PR is constructed from 6061-T6 luminum and anodized to an operational and construction color-coding system. The wetted parts (parts that are directly exposed to and controlling HP oxygen) are rass and stainless steel. The control valve (red) is moved up (open) and down (off) pneumatically via the external control switch. The pressure is supplied by the internal main regulator and is flow restricted so that control line breaches pose no hazards in overt flow of oxygen. 1

It connects directly to any oxygen cylinder with a G-540 (US) or optionally with DIN-477 (European) valve. Flow of oxygen to the user is controlled pneumatically through a set of color-coded pneumatic signal-lines that run to a panel mounted on/off switch. The PR can be ordered in various phases from just the PR regulator to complete PR multi-place built-in aviation oxygen systems. Once your PR system is plumbed, you can use any of our oxygen delivery systems including the EDS pulse-demand system and operate them at the same time others are using MH3 or MH4 flowmeters. maximum number of six (6) self-sealing bulkhead outlets can be mounted in many ways to suite your needs. You can add EDS stations at any time. EDS O 2 D 2 Two-Place Pulse-Demand Oxygen unit The intended use of the PR is for use as an aviation oxygen system where a typical cylinder pressure range would be from 500 to 2,400 psig (nominally 1850 psig). The PR is intended to be used with any off-the-shelf G-540 valve cylinder at pressures up to 3,000 psig. The PR provides a means to remotely control the low pressure outlet circuit for convenience and safety sake. The PR regulator directly connects (by hand) to the service/refill port of any oxygen cylinder with the standard G-540 (US) or optionally DIN-477 (Euro) valve allowing the cylinder to be easily removed for refilling or service. n auxiliary port on the rear side of the regulator body (not shown) is provided for an optional remote oxygen fill station and presure gauge. The PR system is not intended to be the main turn-off for the high pressure of the cylinder used. The PR has a minute amount of weepage under operating pressure, therefore, the main cylinder valve must be turned off during times of storage to mitigate cylinder drainage. The PR operates by using a small fraction of the regulated out let oxygen to pneumatically operate a control valve in the PR body. The 1/8" O.D. pneumatic lines that connect the PR to the on/off control switch are flow restricted so that the regulated lowpressure oxygen does not contribute to any safety hazard in the event shut-off emergencies are required. In distressed situations, the amount of oxygen that may flow from a complete line cut would be about 1/64 liter per minute. This flow is many orders lower than what will be spilled from a severed 1/16" high-pressure remote gauge capillary line. Over-pressure relief of the PR is intrinsic of its design. During times of over pressure by means of the regulator not limiting to the specified pressure, the pneumatically operated control valve then acts as a pressure relief valve where the oxygen from the cylinder will be safely vented through the over-pressure fitting outlets of the installed system. 3

It does not directly turn the high-pressure supply of oxygen on & off. It is not intend to be the main turn-off for the high pressure of the cylinder. The PR may have a minute amount of weepage under operating pressure, therefore, the main cylinder valve must be turned off during times of storage to help mitigate cylinder drainage.

The PR regulator system can be used with virtually any oxygen cylinder with a G-540 valve. Use the EDS O 2 D 1 or O 2 D 2, MH3 or MH4 with the PR regulator system.
