Envoy & Envoy Deluxe Owner’s Manual
This owner’s manual uses signal words recommended by the
American National Standards Institute (see ANSI Z535.4) to designate levels of hazard seriousness. These signal words and their
designations are as follows:
DANGER: Indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This signal word is to be limited to the most extreme situations.
WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
It may also be used to alert against unsafe practices.
Note to European Customers: The Envoy regulator models 350-3110 and 350-3120 have passed EN250:2000 tests for CE Certification. However, they were not tested under EN250:2000 Section 5.11.3 and therefore are not rated for diving in water temperatures below 50° F. (10° C. ). See page 6 for more details.
The Envoy Deluxe models 350-5110 and 350-5120, have not yet been submitted for EN250 Certification and are not CE marked for sale in the European Community.
EN250:2000 Certification extends to 50 m.
Breathing air used in Zeagle Scuba regulators should meet European EN12021 standards.

Limited Lifetime Warranty To The Original Owner
1. Your regulator is guaranteed against defects in materials and workmanship. This guarantee does not cover normal wear, or damage from accident, abuse, neglect, alterations, improper usage, or failure to follow reasonable care and maintenance as outlined in this manual. Under this limited warranty, Zeagle will either repair or replace, at its sole option, any original equipment or parts that fail to perform as intended. Shipping and Labor charges are not included and must be paid by you. To validate your warranty, you must fill out and return your warranty registration card within 30 days of purchase. This Limited Lifetime Warranty excludes filters, hoses, O-rings, diaphragms and mouthpieces, which are warranted for two years from the regulator’s date of purchase. Filling out the card requires printing CLEARLY the serial numbers of both the first and second stages. The first stage serial number is stamped on the first stage on the side of the regulator (fig. 1). The second stage serial number is stamped on the mouthpiece tube (fig. 2). To read this serial number you must fold back the flexible silicone mouthpiece to expose the numbers. Each serial number consists of a pre-fix letter followed by six numbers. All of the digits of both the first and second ID # stages must be CLEARLY printed on Fig. 1 your warranty registration card for your warranty to be activated.
2. For proof of original ownership, you must save the original purchase receipt. It is your record of when and where the regulator was purchased.
It also lets you know when your annual service should be performed.
3. To keep the original-owner Limited Lifetime Warranty in effect, you must have your regulator inspected and serviced annually, within 30 days before or after the anniversary of the purchase date. Failure to do so will invalidate your warranty. This servicing must be performed by an authorized Zeagle dealer. Save the receipts from this servicing for your records.
4. This limited warranty applies only to the original purchaser, and then only to certified divers.
5. Sometimes products from other manufacturers are attached to Zeagle Equipment. This warranty does not cover those other products or make any claims as to the performance or suitability of those other products.
6. This limited warranty applies only to regulators sold in the USA through authorized Zeagle Systems dealers.
7. This warranty gives you specific legal rights. You may also have other rights that may vary from state to state.
8. This warranty applies only to regulators purchased from Authorized Zeagle Dealers located within the United States. The regulator must be picked up by the original owner at the dive store. Regulators shipped to the customer in another location are not covered. Warranty coverage in countries other than the US varies. Outside the US your dealer will be able to get further Warranty information from the Authorized Zeagle Regional Distributor.
Disclaimer And Limitation On Remedy (Some states do not allow limitations on how long an implied warranty lasts or do not allow exclusion of incidental or consequential damages, so the following limitations or exclusions may not apply to you.) Zeagle expressly limits any and all warranties, expressed or implied, to the terms of the limited warranty as set forth above. Your remedies are limited to those contained herein and are in lieu of all other remedies, whether based on breach of warranty or contract, negligence, strict product liability or other tort.
Zeagle specifically disclaims liability for any consequential, special or indirect damages arising out of the use of Zeagle Equipment.
CAUTION Scuba products are subject to conditions of extreme wear and corrosion. Inspection and maintenance are required to ensure continued performance. Zeagle recommends that you have your regulator inspected and serviced once a year on the anniversary date of its purchase at any authorized Zeagle dealer worldwide. Zeagle Scuba equipment should be used by certified Scuba divers only.
1. Scuba diving is an adventuresome activity that involves a degree of risk. Zeagle Systems Inc. Self Contained Underwater Breathing Apparatus (SCUBA) equipment is only to be used by those trained and certified by a nationally recognized scuba training agency. Diving without the necessary training in safe diving procedures, or without observing the practices outlined by your training agency for your level of certification, is extremely hazardous and could result in serious personal injury or death. This owner’s manual is in no way meant to be a substitute for the instruction received from a certified scuba training agency.
2. Zeagle regulators must be serviced only by dealers or technicians trained and authorized to service Zeagle Scuba equipment. At no time should any unauthorized person attempt to repair the regulator or adjust any nuts, bolts or screws other than those used to mount the regulator to, or dismount it from the tank valve. Scuba equipment that is not properly serviced might malfunction during use, putting the diver at risk of serious personal injury or death.
1. The high-pressure outlets (HP Ports) are distinctly larger than the low-pressure outlets. Only devices with fittings, hoses and components designed for the full tank pressure that the regulator will be mounted on, such as Submersible Pressure Gauges, are to be installed in these ports.
2. During installation, the O-ring hose fittings will seal with hand-tight pressure, but may come loose during use if not tightened carefully with a small wrench. Proper torque for the hose fittings is 40-45 in lbs. (4.5 - 5 joules) Excessive tightening will not help the seal and may damage the parts (see DEMA Guidelines No. 101, Low Pressure Hose Installation Caution Statement; ANSI American National Standard for Underwater Safety, paragraph 9.3.1).
COLD WATER DIVING
The Envoy regulator is not specifically designed for use in cold water.
Cold water is defined by C.E.N. standards as water at a temperature of 50 °F (10°C) or lower. In cold water there is a risk of the first or second stage freezing. The risk of freezing is increased as the ambient temperature gets lower, the air flow increases and/or the moisture content of the air supply increases. Regulators for cold water use should have environmentally sealed first stages to prevent water entry and lower the chance of freezing. If you plan to dive in very cold water, Zeagle has other models available that are more suitable. Ask your Zeagle Dealer for details and recommendations.
WARNING Extreme cold water diving such as diving under ice requires specialized training and procedures. Do not attempt these activities unless you are fully qualified and properly equipped to do so safely.
NITROX USE Zeagle regulators are manufactured using materials suitable for use with oxygen enriched gases (i.e., Nitrox, etc.) providing the oxygen content does not exceed 40%. The regulator must be kept “Oxygen Clean” and used only with certified clean air mixtures to maintain this status. Once the regulator is used with air not certified to be clean for enriched air use, the regulator will have to be cleaned again for enriched air use by a certified technician.
DANGER Using nitrox (i.e., gas mixtures containing oxygen in excess of 21%) requires special training and procedures. Improper use of nitrox can lead to personal injury, convulsions, drowning, and death.
DANGER Use of gas mixtures containing oxygen in excess of 40% with this regulator, can lead to fires and explosions, causing severe personal injury and death.
The Envoy First Stage may be attached to your Scuba cylinder by means of the standard yoke assembly for cylinders using a “post” type valve (fig. 3) or the optional DIN connector for cylinders utilizing a DIN valve (fig. 4). Zeagle offers a DIN to Yoke Converter p/n 330-0001 (fig. 5) that allows DIN fitted regulators to be converted for use with a “post” type valve in a few seconds without using tools.
SECOND STAGE FEATURES
The Zeagle Envoy second stage is pneumatically balanced and is among the most advanced diver adjustable breathing systems available. No fixed or “automatic” system can achieve an ideal level of breathing performance under all conditions. Zeagle Envoy Deluxe second stages are equipped with separate diver controls for both cracking resistance and venturi boost. This allows the diver to adjust the complete range of breathing characteristics. By using a combination of the two controls, it is possible to tune the regulator to give virtually ideal performance. The standard Envoy does not have a Resistence Control Knob.
RESISTANCE CONTROL KNOB (Envoy Deluxe Only)
This knob adjusts the spring load on the second stage valve and so varies the initial inhalation effort. To adjust the Resistance Control Knob to the easiest breathing setting, turn the knob fully counter-clockwise (fig. 6).
Sometimes a slight hissing flow of air may be heard at this setting. If this occurs, turn the knob clockwise (fig. 7) just enough to stop the hissing.
NOTE: Ask your authorized Zeagle Scuba dealer for in-store instructions and training on the use of the Resistence Control Knob and the Dive / Predive Venturi Lever. Your dealer will show you how to make adjustments to get the desired breathing results. To actually experience the effects of the adjustment range, the instruction should be conducted with the diver breathing through a regulator attached to a full air supply. The feel of the regulator breathing underwater is of course somewhat different from the feel of breathing above the surface.
OCTOPUS (Alternate Second Stage) USE The diver controls available on the Zeagle standard Envoy second stage make it an excellent choice for Octopus use. An Octopus Regulator is often subjected to conditions that may cause a free-flow. For example, jumping into the water or swimming in a strong current. To minimize this, move the Dive / Pre-Dive Lever forward to the “-” Minus position. When the Octopus Regulator is needed for delivering air to a diver, the Dive / PreDive Lever is moved back to the DIVE “+” position. Although breathing resistance will be somewhat greater, the regulator will still deliver ample air on demand if the Lever is accidentally left in the Pre-Dive position. Longer hoses are available from Zeagle for Octopus use.
WET BREATHINGThe Envoy second stage is much “drier” than many other second stage designs during use. However, it must be remembered that water (including the diver’s own saliva) will always settle to the bottom of the case. If the diver is in an unusual position (i.e. head down or upside down looking upwards) the exhaust valve is no longer at the bottom of the case and the mouth tube is. This means that water will settle in the mouth tube area and sometimes is ingested by the diver. A tendency to wetness is aggravated by slow exhalations while inverted. This is because the exhaust valve is flapping open with little air velocity, thus letting water in. Of course a regulator that begins breathing wetter than it has before, should be checked out by a technician, but avoiding long periods of inversion, and using shorter stronger exhalations if inverted, will keep the interior of the regulator drier.
