Safety Information
Read these instructions carefully before using your regulator, and
keep this manual for future reference.
Following the care and maintenance section at the end of this book-
let will help ensure reliable service.

Limited Lifetime Warranty To The Original Owner
1. Your regulator is guaranteed against defects in materials and work-
manship through the useful life of the product subject to the following
limitations. 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 stages must be CLEARLY
printed on your warranty registration card for your warranty to be acti-
vated. You can also go to www.zeagle.com to register on-line.
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. 3

CAUTION
Scuba products are subject to conditions of extreme wear and cor-
rosion. Inspection and maintenance are required to ensure contin-
ued 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.
WARNING
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.

6
CAUTION
1. The high-pressure outlets (HP Ports) are dis-
tinctly larger than the low-pressure outlets. Only
devices with fittings, hoses and components
designed for the full tank pressure that the regu-
lator 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 fit-
tings 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).

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, convul-
sions, drowning, and death.
Zeagle regulators are manufactured using materials suit-
able 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 techni-
cian.
NITROX USE
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.
WARNING

The Flow-by Piston ReZort body is light and com-
pact. It has five low pressure ports with carefully
designed internal ducting that results in extremely
high flow capabilities for a regulator of this type. The
piston and spring are the only moving assemblies in
the ReZort making it extremely rugged and easy to
service. The ReZort first stage reduces the high pres-
sure air contained in the cylinder to an intermediate
pressure of approximately 135 psi (9.2 BAR). Zeagle
first stages are designed to do this with outstanding
reliability. The ReZort first stage comes in Yoke (310-
5210), and DIN connection (310-5220) versions.
ReZort FIRST STAGE FEATURES
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.
DANGER

ENVOY SECOND STAGE FEATURES
The Zeagle Envoy second stage is pneumatically bal-
anced and is among the most advanced diver adjustable
breathing systems available. No fixed or “automatic”
system can achieve an ideal level of breathing perfor-
mance under all conditions.
DIVE / PRE-DIVE VENTURI LEVER
This lever controls the
sensitivity of the regula-
tor. The Plus and Minus
Positions for the lever
are marked on the case
beside the lever. To avoid
unexpected venturi free
flows at the surface, or
when jumping into the
water, the lever should be set in the PRE-DIVE “-” (for-
ward) position. As soon as the diver is ready to descend,
the lever should be moved to the DIVE “+” (back) position
(as shown in Fig. 3 above).

Fig. 3.

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 / Pre-Dive
Lever is moved back to the DIVE “+” Positive 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.
10
NOTE: Ask your authorized Zeagle Scuba dealer for
in-store instructions and training on the use of the Dive
/ Pre-dive Venturi Lever. Your dealer will show you
how to make adjustments to get the desired breath-
ing 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.

11
WET BREATHING
The 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 at the bottom. This means
that water will settle in the mouth tube area and sometimes is ingested
by the diver. Atendency 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.
PRE-DIVE CHECK
1. Before mounting any regulator onto a tank valve, you must first
open the valve briefly to blow out any water trapped in the outlet area
of the valve. Failure to perform this simple step will often result in water
and other contaminants being blown into the interior of the regulator,
which in turn will cause future mechanical problems in the regulator.
2. Prior to each dive always check to make certain your regulator has
no potential water leaks by inhaling on the regulator with the dust cap
in place or with the regulator mounted on a valve with the air turned off.
You should be able to draw in very little if any air. If you can draw in any
quantity of air, either the exhaust valve is failing to seal properly, or there
may be a pinhole leak in the mouthpiece or second stage diaphragm.
Note, with the dust cap OFF, it is normal to be able to inhale air through
any scuba regulator.

12
If you hear any leaks, turn the tank valve off. Do not use the regulator
until the source of the leak has been found and corrected by an authorized
Zeagle Scuba service technician.
CAUTION
Lifting the tank by the regulator or hoses may loosen a previously tight
connection, which could cause unexpected air loss and put the diver at
risk during a subsequent dive. You could be physically injured by high
pressure air or parts that are propelled by high-pressure air.
WARNING
3. Just before turning on the tank air valve, check to make sure that all
of the hose connections are tight and that the regulator body is aligned
properly, with no kinks in the hoses.
4. Turn the tank valve on slowly, check for air leaks and proper breath-
ing function of the regulator. If any unusual leaks are heard, do not dive
with the regulator. Take the regulator to your authorized Zeagle dealer
for inspection and repair if necessary.
POST-DIVE CARE
1. After the dive, dry the dust cap and place it securely on the regula-
tor inlet. On multiple tank dives, keep water out of the regulator inlet
when changing the tanks. Neglect of these simple procedures is a
major cause of corrosion and wear in scuba regulators.

13
It is essential that your regulator is checked at least annually by an
authorized Zeagle regulator technician. Unusually heavy use, or use
in dirty or contaminated water may result in the need for more frequent
service. Aservice record has been provided at the end of this manual to
assist you in keeping your regulator’s service up to date.
MAINTENANCE
2. With the dust cap securely in place, rinse the first and second stage
in clean fresh water. DO NOT purge the regulator before or during rins-
ing since this may introduce water into the second stage and the low-
pressure hose. After rinsing, reconnect the regulator to an air supply
and thoroughly shake all excess water from the second stage. Press
the Purge cover (with the regulator attached to a pressure source) sev-
eral times to blow the rinse water out of the inner mechanism. Allow
the entire regulator to air dry before storing. For reasons of hygiene,
equipment subjected to frequent use in training, rental, etc. should
finally be rinsed in water containing a suitable sterilizing agent. The best
sterilizing solutions for your regulator are soap based. If any stronger
chemicals are used, make the immersion very brief and rinse the regu-
lator out again thoroughly. Failure to rinse sterilizing chemicals out of
the regulator will cause serious damage to plastic parts of the regulator.
This will result in cracking of hard plastic parts and shrinking or swelling
of soft plastic parts.
NOTE: DO NOT USE SOLVENT CHEMICALS TO CLEAN THE
REGULATOR.
3. Store the clean dry regulator in a clean bag or storage box, away from
sunlight, excessive heat and humidity.
