Limited Lifetime Warranty To The Original Owner
1. Your regulator is guaranteed against defects in materials and work-
manship. This warranty 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
to Zeagle 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. You can also register your regulator at www.zeagle.
com on the internet in the “Product Support” section. The
first stage serial number is stamped on the top flat portion
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 prefix
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 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 through autho-
rized Zeagle Systems dealers.
7. This warranty gives you specific legal rights. You may also have
other rights that may vary from state to state.
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 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 pur-
chase at any authorized Zeagle Scuba 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 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 prop-
erly serviced might malfunction during use, putting the diver at risk of
serious personal injury or death.

CAUTION
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
Cold water is defined as water at a temperature of 50 degrees F (10°
C) or lower. However, in cold water there is a risk of the first or sec-
ond 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. It is not possible to completely
eliminate regulator freezing under all conditions. In order to reduce
the possibility you should:
1. Avoid pushing the purge button in the second stage during cold
water diving operations.
2. Enter the water and submerge without delay.
3. Avoid high rates of breathing, and excessive inflation of buoyancy
devices or dry suits. The deeper the dive the greater the risk.
4. Do not practice buddy breathing, etc. while in cold water.
5. Do not use your regulator to fill lift bags, etc.

7
6. Keep YOUR regulator in YOUR mouth. In an emergency, offer or take
the spare regulator. When taking the spare regulator, do not hit the
purge
button to clear the water (if possible). Clear the regulator with as long a
first exhalation as is safely possible.
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%.
FIRST STAGES
The first stage reduces the high pressure air contained in the cylinder to
a constant intermediate pressure of approximately 135 p.s.i. (9.2 BAR).
Zeagle first stages are designed to do this with outstanding reliability.
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
DANGER
Using nitrox (i.e., gas mixtures containing oxygen in excess of 21%)
requires special training and proceedures. Improper use of nitrox can
lead to personal injury, convulsions, drowning, and death.
Use of gas mixtures containing oxygen in excess of 40% with this regu-
lator, can lead to fires and explosions, causing severe personal injury
and death.
DANGER

8
The 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 477 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. Always mount the regulator on the valve
with the clear diaphragm (and black diaphragm trim ring) downwards as
shown in Fig. 3, 4, 5.
DRY ENVIRONMENTAL SEALING
The Zeagle Flathead-VI dry first stage environmental sealing system
does not require packing with messy silicone oil, or grease. This sys-
tems helps keep the main spring / ambient pressure sensing chamber
clean and dry, and works extremely well in cold water conditions.
SECOND STAGE FEATURES
The Zeagle ZX 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 ZX second stages are
equipped with separate diver controls for both cracking resistance
and venturi boost, to allow 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.
