4.2 DISASSEMBLY OF THE ReZort FIRST STAGE FOR OVERHAUL
To view all of the parts used in the ReZort first stage, look at the inside front cover of this manual. The bracketed numbers in the text refer to the corresponding circled item numbers on the exploded view drawing.
4.2.1 Use 6” or 8” adjustable wrenches to disconnect all hoses from the first stage. Pull back the hose protector from the inlet end of the hose. Inspect the hoses for wear. Pay particular attention to the area where
the metal ferrules meet the rubber hose material. Remove and discard the O-rings from each end of the
hose. Clean, rinse, and blow-dry the interior bores of the hoses. Replace the hoses if necessary.
Note: Hose Protectors are easier to slide back from the 1st stage end of the hose if they are twisted and
pulled when the hose is still installed in the 1st stage. If a hose protector is particularly difficult to pull back,
try removing the hose and soaking the hose protector end in hot water to soften it up. Temporarily reinstall
the hose and try pulling and twisting the hose protector again.
4.2.2 Use a 3/16” Allen wrench to remove all port plugs from the body. Discard the port plug O-rings. (10,
18)
4.2.3 Grip the Body (9) of the ReZort regulator in a smooth and/or soft jawed vise with the Yoke (17) or DIN
Wheel (21) upwards. (See Photo 1 on next page)
4.2.4 Use a 10” adjustable wrench to grip the Yoke Nut (16). Turn the Yoke Nut counterclockwise until it
becomes loose. Remove the Body from the vise and loosen the Yoke Nut the rest of the way by hand.
4.2.5 If the ReZort is a DIN style unit, use a 1/4” Allen Wrench to loosen the DIN Bolt (20).

4.2.6 Remove the Filter (15) and O-ring (14) from the Yoke or DIN Bolt.
4.2.7 Install the ReZort again into the vise with the Cap end up (See Photo 2). Remove the Cap (2) from
the Body (9).Remove any Spacer(s) (8), the Spring (7) and the Piston (4) from the Cap. Remove and discard the O-rings (3, 5) from the piston. Whenever possible, try to remove the O-rings by pinching them with
the fingers and rolling them out of the groove.
! WARNING ! If a sharp pick is used to remove the O-rings, it should be made from soft brass,
not steel. ANY scratches left in the groove when removing O-rings will cause leaks (bubbling out of the Cap
ambient pressure ports) and the piston will have to be replaced to stop these leaks.
7
4.2.8 Remove the Seat (6) from the Piston (4) by
pushing it out with a 1/16” drill bit. Place one end of
the drill bit on a flat hard surface. Lower the large end
of the Piston over the drill bit until the flat end of the
drill bit rests against the back side of the Seat. Push
the Piston firmly down straight on the drill bit, until the
seat is pushed out of the piston. Discard the old Seat.
See Photo # 3.

4.3 Cleaning and Inspection of the 1st Stage
4.3.1 Clean all metal parts of the first stage in an ultrasonic cleaner or cleaning solution. See Section 6.3
for recommendations on cleaning solutions. Remove the O-rings before cleaning any metal parts since
the soft O-ring material will absorb cleaning energy from the ultrasonic cleaner reducing its effectiveness.
If major visible corrosion or deposits exist on parts, use a bristle brush, wooden, or plastic stick to rub the
deposits off. Allowing acidic cleaning solutions to do all of the work if deposits are severe, will result in
damage to internal chrome plating which will make parts even more susceptible to future corrosion.
4.3.2 Remove the regulator parts from the cleaning solution. Rinse with clean fresh water, then blow
internal passageways dry with clean, dry compressed air.
4.3.3 Inspect all O-ring grooves for scratches or wear. If the regulator was leaking air because of scratches or wear, replace the parts. If some corrosion deposits persist, carefully wipe them away with a plastic
scrubbing cloth or plastic or wooden dowel. Blow any resulting dust out of the regulator parts.
4.3.4 Closely examine the sealing cone (orifice) in the Body (9) where the Seat (6) of the Piston (4) seals.
Minor scatches can sometimes be buffed out with a wooden or a buffing stick of suitable size.
4.4 PRELIMINARY ASSEMBLY OF THE FIRST STAGE
4.4.1 To determine the identity of each O-ring in the Service Kit, remove them from the bag and use
the O-ring Identification Chart on the front page of this manual. Lay each O-ring over its corresponding
picture on the page and read the description. Before installing new O-rings into the regulator, lightly lubricate the O-rings with LTI Christo-Lube 111® (for enriched air regulators), or Dow-Corning 111® silicone
grease. The most effective way to lubricate the kit O-rings is to put them in a small plastic bag with a pea
sized amount of grease. Rub the O-rings and grease together in the bag until all the O-rings are coated
evenly. Try not to wipe the lubrication off the O-rings when assembling them onto other parts.
4.4 PRELIMINARY ASSEMBLY OF THE FIRST STAGE
4.4.1 To determine the identity of each O-ring in the Service Kit, remove them from the bag and use
the O-ring Identification Chart on the front page of this manual. Lay each O-ring over its corresponding
picture on the page and read the description. Before installing new O-rings into the regulator, lightly lubricate the O-rings (except the Filter O-ring (14) with LTI Christo-Lube 111® (for enriched air regulators),
or Dow-Corning 111® silicone grease. The most effective way to lubricate the kit O-rings is to put them in
a small plastic bag with a pea sized amount of grease. Rub the O-rings and grease together in the bag
until all the O-rings are coated evenly. Try not to wipe the lubrication off the O-rings when assembling
them onto other parts.
4.4.2 Install the new Filter (15) and unlubricated O-ring (14) into the Yoke Bolt (16) or DIN Bolt (20),
depending on which inlet style your ReZort has.
4.4.3 Install the Yoke Bolt into the Yoke (17) or the DIN Bolt into the DIN Wheel (21).
4.4.4 With the Body held in a smooth jawed vise, tighten the Yoke Bolt with a 10” adjustable wrench, or
the DIN Bolt with a 1/4” Allen Wrench. Both styles are tightened to 20-25 ft/lb (27-34 Nm).
4.4.5 Use the fingertip to spread a film of grease on the inside of the Cap (2) where the large O-ring (3)
slides.
Installing the Seat (6) into the Piston (4)
Photo 5
4.4.6 Place the piston Seat (6) on a clean flat surface and press the Piston (4) stem straight over the seat
until the new seat is installed into the end of the Piston. See Photo 5.
4.4.7 Install the pre-lubricated (see 4.4.1) O-rings (3, 5) onto the piston. Carefully guide the large end of
the Piston into the Cap until it bottoms. Use a gentle rocking motion of necessary to move the Piston into
the Cap, but do not cock it at too severe an angle since this may cause the Piston to gouge the sealing
surface of the Cap.
9
4.4.8 Hold the Body (9) so that the Cap threaded end is facing up. Use the same number of Shims (8)
that were installed in the Spring Cavity when you took the ReZort apart. If there was one Shim, it goes on
the Body side of the Spring (7). If there were two Shims, install one at each end of the Spring.
4.4.9 Install the Spring (7) on top of the Shim.
4.4.10 Lubricate the threads on the Cap (2) with grease. Bring the Cap with its Piston (4) installed, over the
Spring and Shim sitting in the cavity of the body and screw them together as far as you can by hand.
4.4.11 Use a wrench to snug the Cap (2) onto the body with 1-5 ft/lbs (1.4- 7 Nm) of torque.
4.5 SET-UP AND TESTING THE FIRST STAGE
Note: The ReZort regulator is an unbalanced piston 1st stage. Intermediate pressure will begin in the
higher end of the range with high tank pressures and drop as the tank pressure decreases with use. For
this reason, the ReZort’s intermediate pressure must be tested and set at the highest inlet (cylinder) pressure that the regulator is going to see during use. This is usually 3000-3500 psi (207-241 bar).
4.5.1 Install the normal hoses, fittings and all but one LP Port Plug into the ports of the 1st stage.
4.5.2 In the remaining open port, install an intermediate pressure gauge. Make sure at least one of the
ports has a functioning 2nd stage installed or that the intermediate pressure gauge has an Over-Pressure
Relief Valve. Attach the ReZort to a Valve on a full Scuba Cylinder
4.5.3 Turn the Tank Valve on SLOWLY turning the valve’s handwheel counter-clockwise while listening for
any unusual air leaks. If any are heard, turn the air off immediately and determine the source of the leak.
If no leaks are found, watch the intermediate pressure gauge reading rise as you continue turning the air
on slowly. It should stop before 160 psig (11 bar).
4.5.4 If the pressure gauge continues to rise above 160 psig (11 bar), turn the air supply off immediately
and inspect the regulator to determine the cause.
4.5.5 Position the intermediate pressure gauge so the dial can be seen. See Photo 6.
Checking the Intermediate Pressure with a Gauge
Photo 6
11
4.5.6 Depress the 2nd stage purge cover fully, then release it several times to clear particles from the
regulator, and to work the internal parts into place. To prevent uncontrolled free flows after pushing the
purge cover, keep the venturi control lever on the second stage in the “-” (negative position).
4.5.7 The pressure range for Zeagle ReZort Regulators at 3000 psi inlet pressure is 130-150 psi ( 9-10
bar). Add Shims (8) in either side of the spring (7) to raise the intermediate pressure. Remove Shims to
lower the pressure. The pressure increase per shim is not linear due to the rate of the spring, so no specific increase per spring can be given. Generally, only add a shim if the intermediate pressure (when the
cylinder pressure is 3000 psi) is below the 130-150 (9-10 bar) range. Adding just one shim under these
conditions will not push the intermediate pressure above the maximum 150 pressure. Do not aim for a
specific pressure within the range, just add or remove shims to get the pressure within the range. The
optimal intermediate pressure for Zeagle ReZort regulators is 140 psi (9.7 bar), but any setting between
130 and 150 psi (9-10 bar) at 3000 psi (207 bar) inlet pressure will provide good stable performance.
4.5.8 After reaching the proper pressure setting, push the purge cover on the second stage again several
times and watch how the intermediate pressure reading responds. When the purge cover on the second
stage is depressed, the intermediate pressure reading will drop. When the purge cover is released the
pressure should return immediately to the proper lock-up pressure and stay there.
4.5.9 Let the regulator sit with the tank valve turned on for several minutes. The intermediate pressure
reading may rise about 3 psi in the first three seconds after lock-up, but after that it should not rise more
than another 4 psi (.3 bar) in five minutes. If it rises more than 4 psi refer to the Trouble-shooting Section
6.1 of this manual.
Note: Never set the output pressure of the first stage above 150 psig (10 bar).
5.0 ENVOY SECOND STAGE SERVICE PROCEDURES
The ReZort regulator comes equiped with a Zeagle Envoy 2nd stage. Procedures covered in this manual
section apply to the ENVOY second stage. To access the exploded view of this model open the back
cover of this manual. This second stage is used as a primary unit, gray or black purge cover and 30” hose
(model assembly number 320-3115) and as an advanced octopus unit, yellow purge cover and 36” hose
(model assembly number 320-3110). See the picture on the front page of this manual section to identify
this model type. The serial number for this model always starts with “J”. The number can be seen by
curling back the mouthpiece and looking at the end of the mouth-tube.

5.2
DISASSEMBLY OF THE SECOND STAGE
! WARNING ! NEVER tighten the hose fitting to the first stage with more than 40 in. lbs. (4.5 Nm)
of torque. The inlet hose fitting can be weakened by over tightening.
To view the complete parts list of the second stage, open the back cover of this manual.
5.2.1 Use the 6” and 8” adjustable wrenches to loosen the hose nut from the valve tube (21). Remove the
hose assembly (30) from the second stage. Inspect the hose assembly for any cuts or cracks, especially on
the hose at the metal ferrules. Remove and discard the O-rings from each end of the hose. Clean, rinse, and
blow-dry the interior bores of the hoses. Replace the hose assembly if any cuts or cracks are found.
5.2.2 Remove the mouthpiece (12) by cutting the mouthpiece tie (11) with side cutting pliers. Discard the old
mouthpiece tie. Examine the condition of the mouthpiece. Pay particular attention to the area on top just
behind where the old tie tightened. This is a prime area for small holes to develop. If the mouthpiece is in
good condition, it can be reused.
5.2.3 Remove the exhaust tee (13) from the case by pulling it back and off the top edge of the retaining flange
on the housing. Note: The exhaust tee can be removed more easily if hot water from a tap is run over and
through it for about 1 minute.
5.2.4 Before removing the exhaust valve (14) from the housing (10), bend the valve over as far as it will go
from the top, bottom, left, and right sides. If it fails to snap back quickly, and does not lie perfectly flat against
the housing exhaust grid, the valve should be replaced. If it does snap back satisfactorily, remove it by pulling
it out with your fingers. Inspect the sealing edges. If they appear smooth, and the locking tab on the nipple
is good, the valve can be reused.
5.2.5 Unscrew the cover ring (1) from the housing (10).
5.2.6 Remove the diaphragm cover (3) and the diaphragm (4) from the housing (10).
If the cover is difficult to remove you can try several methods to loosen it;
- Heat the 2nd stage body surrounding the Ring by running hot water from a tap over it. When the plasric is
hot, it will expand and loosen the threads.
- Rubber pads are available to use in the hand to loosen tight jar lids. These pads will allow you to get a
better grip on the Cover Ring (1)
- Zeagle sells a Cover Ring Removal/Purge Cover Aligning Tool.The part number is 347-1005 See photo 7.

One side of the 347-1005 tool is used to engage the notches on the Cover Ring (1). Once the notches are
engaged by the tool, it is easy to turn the Cover Ring off of the Housing by turning the tool counter -clockwise.
See photo 8. Later versions of the 347-1005 tool are made from black plastic.
Photo 8
5.2.7 For future reference, look at the lever (19) at this time. Notice how the pivot end of the lever is held into
the valve tube (21) by two plastic flanges on the housing. Note this positioning for re-assembly.
5.2.8 Hold the diaphragm up to a light source. Gently stretch the diaphragm and look for tears or pinholes.
If any are found, replace the diaphragm.
5.2.9 Loosen and remove the nut (7) from the valve tube (21)
5.2.10 Remove the plastic bushing (8) from the valve tube.
5.2.11 Remove and discard the O-ring (9) from the valve tube.
5.2.12 Use a 1/4” Allen Wrench to turn the black plastic spring adjust plug (29) fully counter clockwise until
it comes to its stop. Do not use an unreasonable force to do this. Stop turning the plug as soon as a resistance is felt.
5.2.13 Depress the lever (19) fully onto the valve tube. Grasp the tab of the venturi control lever (16). While
pulling on the venturi control lever, push the valve tube assembly out of the housing (10).
5.2.14 Remove the venturi control lever (16) from the valve tube assembly. Remove and discard the O-ring
(15) from the venturi control lever.
5.2.15 Use a 1/4” Allen wrench to turn the spring adjust plug (29) clockwise 1/4” turn. The pin (20) will fall
out of the valve tube or can now be easily removed.
5.2.16 Turn the spring adjust plug (29) counter clockwise to remove it from the valve tube. Remove and
discard the O-ring (28).
5.2.17 The balancing chamber (26), spring (25) and piston (23) are removed at this time. They will often fall
out if the valve tube is tipped on its end. If the piston will not fall out, the lever (19) can be moved through its
full arc. If the piston still does not come out a 5/32” (4-5 mm) Allen wrench can be inserted through the male
threaded end of the valve tube, through the seat (18) to gently push the piston out.
5.2.18 Remove and discard the O-ring (27) from the outside of the valve tube (21).
14
5.2.19 The lever (19) should not be removed from the valve tube unnecessarily. However, it can be removed
from the valve body by carefully springing out one of the feet and pivoting it over the valve tube body. Do not
over-bend the lever legs. Straighten the legs if they are bent outward from parallel.
5.2.20 Remove and discard the seating seal (22) from the piston (23).
5.2.21 Remove and discard the very small O-ring (24) from the piston. This can be done by pinching a section of the O-ring out of the groove with the fingernails. Then flip the O-ring off the end of the piston stem.
DO NOT USE SHARP METAL PICKS! Metal tools will damage the O-ring groove, which will cause a small
continuous second stage leak.
5.2.22 Use a 3/16” Allen wrench or the Zeagle 2nd Stage, Inline Adjusting Tool - 3/16” Hex (p/n 347-0002) to
turn the seat (18) counterclockwise enough turns to fully disengage the threads from the valve tube (21).
5.2.23 After the threads are disengaged, remove the seat (18) from the valve tube (21) by pulling and turning
counterclockwise at the same time. The seat will usually come out on the end of the Allen wrench. If it will
not come out, it can be pushed out with a soft wooden dowel however, care must be taken not to damage
the seat if it is pushed out.
5.2.24 Remove and discard the O-ring (17) from the seat.
5.3 CLEANING AND INSPECTION OF THE 2nd STAGE
5.3.1 Rinse all plastic and silicone parts in fresh warm soapy water solution. Rinse with clean warm water
and then blow the parts dry with compressed air to remove any sand and dust particles.
! WARNING !
DO NOT use vinegar or other acid solutions on the plastic parts since this will cause the plastic to become
brittle!
5.3.2 If necessary because of deposits or corrosion, clean all metal parts of the second stage in an ultrasonic
cleaner or cleaning solution. See Section 6.3 for recommendations on cleaning solutions.
5.3.3 Inspect the housing (10) for any cracks or nicks. Look particularly closely at the area where the exhaust
valve (14) seals and where the bushing (8) clamps. Replace the housing if any cracks are found.
5.3.4 Inspect the sealing surface on the seat (18) (where the seating seal (22) seals) for any nicks or scratches. Replace the seat (18) if any serious defects are found at the sealing area, or if the threads appear worn
out.
5.3.5 Blow all dust and debris out of the orifice with clean compressed air.
5.3.6 Inspect the exhaust valve (14). Look carefully at the base of the barbed nipple where it comes out of
the middle of the valve. Look for any tearing at this point. Replace the valve if any tears are found. Replace
the valve if nicks or tears are found at the sealing edges of the valve.
5.3.7 During an Annual Overhaul, all parts included in the Annual Service Kit are replaced no matter what
the condition of those parts. Carefully examine all other parts of the second stage for signs of deterioration.
Replace those parts too where necessary
15
5.4 PRELIMINARY ASSEMBLY OF THE SECOND STAGE
5.4.1 Ensure that all parts are clean. To determine the identity of each O-ring in the Second Stage Service
Kit, remove them from the bag and use the O-ring Identification Chart on the back page of this section. Lay
each O-ring over its corresponding picture on the page and read the description.
Before installing new O-rings into the regulator, lightly lubricate the O-rings with Dow-Corning 111® Silicone
Grease or LTI Christo-Lube 111® (EXCEPT O-ring (9) that goes over the valve tube (21) male threaded
end).
5.4.2 Install the exhaust valve (14) into the case by inserting the nipple into the square hole from the outside
of the case. Reach inside the case and pull the nipple firmly with the fingers until you hear or feel it “click”
into place. Inspect the exhaust valve to see that it is properly seated. Take care not to get any lubricating
grease on the exhaust valve during this procedure.
5.4.3 Install a new O-ring (27) onto the outside of the valve tube (21).
5.4.4 If the lever (19) was removed, carefully re-fit it into the valve tube (21). To orient the
lever properly, hold the valve tube with the external threads to the left. Turn the valve tube until you can see
the hole where the air exits the valve tube (indicated by the arrow in photo). The lever is inserted so that
it hangs down and curves leans to the right. See Photo 9. Work the lever into the valve tube one foot at a
time so the lever legs are spread outwards as little as possible.
Photo 9
5.4.5 Insert the new seating seal (22) into the white piston (23).
5.4.6 Install the lubricated small O-ring (24) onto the piston tip.
5.4.7 Install the spring (25) onto the piston and the balance cylinder (26) onto the piston to make the shuttle
valve assembly.
5.4.8 Insert the shuttle valve assembly you have just assembled, into the valve tube (21) at the end with the
raised collar (opposite the external threaded end). See Photo 10.
16
Photo 10
5.4.9 When the shuttle assembly is inserted into the valve tube, it is important that the “L” shaped foot
on the piston section engages properly with the lever tabs that extend through the holes in the valve
tube. In Photo # 10, the “J” shaped foot has been highlighted with black marker so you can see the
“J” clearly. The piston is normally all white.
5.4.10 Insert the shuttle valve assembly as shown in Photo # 10. Push the assembly all of the way
into the valve tube. The first thing that might hang up on the tabs of the lever is the black seating
seal. Wiggle the lever to get this past the tabs. When the “J” shaped feet get to the lever tabs they
will lift the lever inwards as you push the assembly in.
5.4.11 Install a new well lubricated O-ring (28) onto the spring adjuster plug (29).
5.4.12 Insert the spring adjuster plug into the valve tube over the shuttle valve assembly you just
installed.
5.4.13 Turn the spring adjuster plug clock-wise until the O-ring and flange have passed the hole where
the pin (20) is installed.
5.4.14 Install the pin (20) into the valve tube (21).
5.4.15 Back the spring adjuster plug out counter-clockwise until it tightens against the pin (20), holding it in place.
5.4.16 Install the new O-ring (15) onto the venturi control lever (16).
5.4.17 While holding the tabs in place in the valve tube with two fingers, depress the lever (19) and
the slide the venturi control lever (16) into place on the valve tube (21).
5.4.18 Install the valve tube assembly into the housing (10). After assembly, make sure that the pivot
end of the lever is held into the valve tube (21) by two plastic flanges on the housing just as they did
when you took the housing apart (see step 5.2.7).
17
5.4.19 Install the O-ring (9) over the external threaded end of the valve tube (21).
5.4.20 Install the bushing (8) (flat side facing the body) over the external threaded end of the valve tube.
5.4.21 Install the nut (7) over the external threaded end of the valve tube. Tighten the nut snuggly 1-2 ft/lb
(2-3 Nm) with a wrench.
5.4.22 Install the new lubricated O-ring (17) onto the seat (18).
5.4.23 Use the 3/16” Allen wrench or the 2nd Stage, Inline Adjusting Tool - 3/16” Hex (p/n 347-0002) to install
the seat into the valve tube.
5.4.24 Tighten the seat (18) clockwise with the Allen wrench. It is important that the final adjustment leaves
the lever with about 1/8” (3.2 mm) free movement at the end, to allow for the natural wear of the seating seal
(22) during the use of the regulator. Adjust the seat (18) in, while moving the end of the lever up and down
with the tip of your finger. When the seat is too far out (counter-clockwise) you will feel a firm springiness
with no free movement. When the seat is too far in (clockwise) you will feel a great deal of looseness at the
end of the lever. You want the seat (18) to be positioned so that you feel the 1/8” (3.2 mm) free play when
you move the tip of of the lever with your finger. See photo 9.
Inline Adjusting Tool Method:
Install the Zeagle Inline Adjusting tool p/n 347-0002 between the hose and the 2nd stage body. Turn the
plastic spring adjuster plug (29) on the regulator all of the way out (counter clockwise). Use the inline tool
to just begin to thread the seat (18) into the valve tube. CAREFULLY turn the tank air on just barely enough
to let airflow through the regulator. You will hear a hiss of air coming from the second stage. Turn the
seat clockwise (toward the seal). As soon as the seat makes contact with the seal, the air will stop flowing
through the second stage. Adjust the seat further so that there is no hissing noise and the lever has 1/8”
(3.2 mm) free play when you move the tip of of the lever with your finger. See photo 11.
Note: Depress the lever (19) while moving the seat with the wrench. This prevents premature indentation
and wear of the seal (22).
Photo 11
5.4.25 Install the exhaust tee (13) onto the case by hooking the tee over the flat part of the flange and then
working it over the rest of the flange. This operation is made much easier if the tee is immersed for one
minute in hot tap water to soften it temporarily.
18
5.5 SET- UP OF THE SECOND STAGE
For the following adjustments, the cover and diaphragm must be removed.
5.5.1 Turn the spring adjust knob plug (29) out counter-clockwise all the way. IF the regulator is to be used
as an Octopus unit, then turn the adjust knob plug (29) back in clockwise one turn.
5.5.2 Install the new O-rings (31,33) onto the hose assembly (30). Install the hose between a serviced first
stage and the second stage, tighten snugly. Use two wrenches to tighten the second stage hose connection.
Note: Attach the second stage to the overhauled and properly adjusted first stage that it is going to be used
with, mounted on an air tank filled to the maximum pressure the regulator is going to be used with. Install an
intermediate pressure gauge into one of the low-pressure ports.
5.5.3 Carefully turn the air on. After adjusting the second stage as outlined in assembly step 5.4.24 in this
manual, the lever (19) should be should be slightly loose against the “L” shaped foot of the shuttle valve
assembly. See Photo # 9. There should be about 1/8” (3.2 mm) of free play at the end of the lever. There
should be no air leaking from the second stage with proper intermediate pressure applied to the hose. If
there is air leaking from anywhere on the second stage, correct the problem before going further. The best
test to check for the slightest leaks is to immerse the second stage (with no cover or diaphragm installed)
under pressure in water and look for bubbles indicating a leak. Correct the problem if leaks are found. See
Troubleshooting section 6.1 for help.
5.5.4 Work the lever up and down a few times while the regulator is pressurized. Each time the lever is
released, no air hissing should be heard.
5.6 FINAL ASSEMBLY OF THE SECOND STAGE
5.6.1 Install the diaphragm (4) into the housing (10) so that it sits evenly on the ledge.
5.6.2 Install the diaphragm cover (3) over the diaphragm. The diaphragm cover (3) is the best tool to align the
diaphragm into the body. Push the cover firmly over the diaphragm so the diaphragm is seated properly.
5.6.3 Install the purge dome (2) into the cover ring (1).
5.6.4 Screw the purge dome and cover ring into housing. Adjust the purge dome in the cover ring so that
the Zeagle logo sits properly when the cover ring is tightened firmly hand tight. If the Zeagle “Z” logo is not
straight, it can be easily aligned using one side of the Cover Ring Removal/Alignment Tool p/n 347-1005.
5.6.5 Install the mouthpiece (12). Be sure to position the mouthpiece so that the overbite where the top teeth
fit, is on the top.
5.6.6 Install the new mouthpiece tie (11) from the service kit. Position the tie lock on the side of the mouthpiece. Tighten the tie securely and cut off the excess.
! WARNING !
NEVER tighten the hose with more than 40 in. lbs. (4.5 Nm) of torque. The inlet hose fitting can be
weakened by over tightening.
19
5.7 TESTING OF THE SECOND STAGE
A. INHALATION EFFORT:
5.7.1 With air pressure applied, turn the spring adjust plug (29) fully counter-clockwise. Move the
venturi lever to the “+” position. Depress and release the purge dome. A large continuous free-flow
should result. Move the venturi lever towards the “-“ position. With no other intervention, by the time
you get the lever 2/3 of the way to the “-“ position the free-flowing should stop. This test shows the
regulator is performing as it should. It is not necessary, but you can perform further inhalation tests.
5.7.2 If you have no instrumentation, breathe on the regulator to test the breathing effort. With the
adjusting knob turned fully clockwise, and the venturi lever in the full “-“ (pre-dive) position, the regulator will be relatively hard to inhale on but the purge dome must still purge when depressed.
5.7.3 With the spring adjust plug turned fully counter-clockwise, then one full turn in (clockwise), and
the venturi lever in the full “+“ (dive) position the regulator will be easy to inhale on. It is important to
note that although the breathing efforts are very different in these two positions, the ultimate air delivery capacity of the regulator is essentially the same in either position.
5.7.4 If a water column or water manometer is used to check inhalation effort, it should not exceed 2”
(50 mm) w. c. at cracking with the adjuster knob in the minimum effort position.
Note: These Zeagle regulators have been designed and built to perform with the “Best of the Best”
in underwater breathing effort. They also have design features that were influenced by the desire to
make the regulator stable. The regulator is VERY easy breathing underwater, and yet resists going
into free-flow by just being bumped on the surface.
If the technician wants to lower the cracking effort to the lower end of the range, refer to the trouble
shooting section of this manual (6.1)
5.7.5 Move the venturi adjusting lever (16) through its full range of movement while inhaling on the
regulator. You should feel an easier inhalation effort in the “+” position than the “-“ position.
B.
EXHALATION EFFORT:
5.7.6 If you do not use instruments to check the exhalation effort, the flow should feel smooth and
unrestricted.
5.7.7 If you use a water column, it should not exceed 1/2” w.c. (13 mm) at one atmosphere.
5.7.8 Brand new exhaust valves will sometimes adhere slightly to the case, causing a slight increase
in exhalation effort. This condition will disappear with use.
20
C.
LEAK TEST:
5.7.9 Disconnect the air supply. Purge the regulator of all positive air pressure.
5.7.10 Slowly immerse the second stage in a pan of water with the mouthpiece pointing straight
up.
5.7.11 Immerse the regulator until the water is 1/4” to 1/8”(.64 to .32 cm) from the lip of the
mouthpiece.
5.7.12 Hold the regulator in this position for one minute and then slowly raise it out of the
water.
5.7.13 Tip the regulator mouthpiece downward and watch the inside of the mouthpiece tube. If
any water escapes from the mouthpiece tube, check for the source of the leakage.
D.
INTERMEDIATE PRESSURE AIR LEAKS:
5.7.14 Attach the regulator first stage to a tank short enough to totally submerge the first and
second stage in your filling station cooling water. Adjust the breathing effort adjustment plug to
the minimum breathing effort position.
5.7.15 With the tank valve still turned off, flood the second stage completely with water, and
then position it mouthpiece up.
5.7.16 Turn the tank air valve on slowly and then watch for any leaks in the first or second
stage. If leaks are seen coming from the second stage, repeat the test with the cover assembly
removed. You will be able to see more clearly exactly where the leak is coming from.
5.7.17 Repair any leaks.
6.0 HELPFUL HINTS

on high end of
range
The spring (25) can be conditioned to a lower thrust. This is done by squeezing it down (with a vise or fingers) to near solid height (.350”) where the
space between the coils is the same as the thickness of the spring wire. Do
not squeeze the spring coils completely closed as this will result in too low a
cracking effort.
Note: This will lower the cracking effort in air, but will have little or no effect on
the underwater performance. It is usually not necessary and should only be
done if the customer understands that a low cracking effort makes a regulator more prone to hissing and will probably need more frequent adjusting. If
the spring is over squeezed during this conditioning, so that the coils touch
each other, the 2nd stage may hiss when the adjust plug (29) is turned all
of the way out. Turning the plug in (clockwise) slightly will stop the hissing if
this is the case. If the hissing does not stop, the seat (18) needs adjusting,
or the seal (22) needs replacing.
B. CREEPING INTERMEDIATE PRESSURE:
POSSIBLE CAUSE

6.2 PARTS CLEANING RECOMMENDATIONS
6.2.1 Regulators that see heavy use, particularly those used in salt water, often require extra
effort to remove dirt and corrosion from the parts of the regulator. Some suggested cleaning
solutions are listed at the end of this section, and there are probably many others being used
successfully. The following are a few general suggestions we can make.
6.2.2 Don’t expect your cleaning solution to do all the work in a matter of seconds. If the solution cleans extremely rapidly, it is probably too strong and is etching the finish on the parts.
Use a wooden or plastic stick or a soft bristle brush to help get rid of the thickest deposits. Take
special care not to damage orifice sealing areas.
6.2.3 Soft parts absorb ultrasonic energy. Remove all O-rings and seals from metal parts before
cleaning them. If possible, do not clean plastic parts with the metal parts, or at least understand
that every plastic part you put into the ultrasonic cleaner is slowing down the ultrasonic cleaning
process for the rest of the parts.
6.3 COMMONLY USED CLEANING SOLUTIONS
SOLUTION
Hot Soapy water
Vinegar and water (equal part solution)
(weaker solution in Ultrasonic Cleaner)
Simple Green ® and Water
Cleaning solutions recommended by ultrasonic cleaner manufacturers
6.4
COMMENTS
Preferable. Good for plastic, silicone and
plated metal parts.
Ingredients easily available. Approx. 15 min.
cleaning time. May damage chrome finish.
Never use on plastic parts. Vinegar dissolves
the plastics in most polymers making them
brittle and more prone to breakage.
Simple Green® is a readily available
degreaser. Read the product label for mixing
ratios with water.
The preferred choice. Check with the manufacturer for strengths and recommended uses
for their cleaners. Choose soap solutions
over acidic ones.
HANDLING TIPS
How your customers treat their regulators will directly influence the unit’s function and durability.
Following are a few tips that you can pass on to your customers to help assure the durability of
their Zeagle Scuba Regulator.
A. PRE-DIVE CHECKS:
6.4.1 Check the hoses and hose connections for cuts, abrasions or other signs of damage
before mounting the regulator on the tank valve. Slide the hose protectors back to inspect the
areas of the hose normally covered. Be sure all hose connections are tight.
24
6.4.2 Just before mounting the regulator on the valve, always turn the valve on briefly to blow
any trapped water out of the valve. There is often salty water trapped in the outlet side of the
valve. This entrapped salt water being blown through the interior of the regulator is the number
one source of internal corrosion and problems with Scuba regulators.
6.4.3 Before turning on the tank air valve, check to make sure that the yoke nut or DIN connection is tight and the regulator body is aligned properly, with no kinks in the hoses.
6.4.4 Turn the tank valve on slowly and listen for leaks. If any leaks are found, replace or repair
parts as recommended.
6.4.5 Never lift the tank/BCD assembly by the regulator or hoses.
6.4.6 Surface-test the regulator by breathing lightly through the mouthpiece. Depressing the
purge button above the water’s surface is not an effective or thorough method for testing the
function of the regulator.
B. POST-DIVE CARE:
6.4.7 After the dive, blow all water out of the dust cap with clean dry air or dab the water out with
an absorbent cloth and place the cap securely on the regulator inlet. On multiple tank dives,
use great care to keep salt water out of the regulator inlet when tanks are changed. Neglecting
these simple procedures is another great cause of corrosion and wear in Scuba regulators.
6.4.8 With the dust cap securely in place, rinse the first and second stages in clean fresh water.
DO NOT depress the purge button before or during rinsing since this may introduce water into
the second stage and the low-pressure hose. Shake or blow all excess water from the second
stage and allow the entire regulator to air-dry before storing.
6.4.9 Store regulator in a clean bag or storage box, away from sunlight, excessive heat and
humidity.

7.1
WARRANTY AND MAINTENANCE INFORMATION
PROPER PROCEDURE FOR SERVICE PAPERWORK (USA)
7.1.1 Make sure your service location has an adequate supply of the three part “Zeagle Service
Order / Parts Request” forms. One of these carbon-paper forms is required to get credit for
parts used in any warranty replacement. Contact Zeagle Customer Service for replacement
forms.
7.1.2 When the regulator is received from the customer for servicing, verify that they are the
original retail owner of the regulator and that they have had the regulator serviced annually at
an Authorized Zeagle Dealer. You can use your records for this, or receipts they have. If they
are not the original owner or have not had the regulator serviced annually, the warranty is no
longer in effect.
25
7.1.3 Fill out the Zeagle Service Order / Parts Request form. PRINT CLEARLY! If you use service kits, you only have to use the service kit part number(s) to represent all of the parts in that
kit. Parts other than those in the kits have to be listed individually. The reason for replacing the
part also has to be listed on the form.
7.1.4 Attach all of the old parts that were replaced under warranty in a plastic bag and attach it
to the Zeagle Service Order / Parts Request form.
7.1.5 If a body or housing is replaced, the replacement parts will have different new serial numbers. Note the new serial # in “Description of Part” section of the Zeagle Service Order / Parts
Request form. Write the old number in the Serial # section. The dive store and the customer
should keep records of this serial number change. Use the new numbers in future warranty
claims.
7.1.6 Contact Zeagle Customer Service and ask for an RA (Return Authorization) number for
each group of Zeagle Service Order / Parts Request forms you are going to send in. YOU MUST
GET A RA# BEFORE RETURNING ANY PARTS TO ZEAGLE. Due to high volume and a desire
to move promised items through the service department quickly, boxes arriving without a RA# will
be put at the end of the line and will be opened when all other work on properly RA numbered

SCHEDULED MAINTENANCE
7.2.1 To keep the owner warranty in effect, your customers must have their regulators inspected
and serviced annually (within six weeks before or after the anniversary of the date of purchase)
by an authorized Zeagle Dealer. Failure to do so invalidates the warranty.
7.2.2 Even with infrequent use, the regulator should be serviced annually to ensure proper performance and satisfy warranty requirements.
7.2.3 After calling Zeagle Customer Service at (813) 782-5568 for an RA number, Zeagle Scuba
parts and warranty forms are sent to the following address:
