INTRODUCTION
This manual provides factory prescribed procedures for the correct service
and repair of the Aqua Lung or Apeks products described in this manual. It is
not intended to be used as an instructional manual for untrained personnel.
The procedures outlined within this manual are to be performed only by
personnel who have received Factory Authorized training through an
Aqua Lung or Apeks Service & Repair Seminar. If you do not completely
understand all of the procedures outlined in this manual, contact Aqua Lung
to speak directly with a Technical Advisor before proceeding any further.
GENERAL GUIDELINES
1. In order to correctly perform the procedures outlined in this manual, it
is important to follow each step exactly in the order given. Read over the
entire manual to become familiar with all procedures before attempting to
disassemble the product in this manual, and to learn which specialty tools
and replacement parts will be required. Keep the manual open beside you
for reference while performing each procedure. Do not rely on memory.
2. All service and repair should be carried out in a work area
specically set up and equipped for the task. Adequate lighting, cleanliness,
and easy access to all required tools are essential for an efcient repair facilit y.
3. As the product is disassembled, reusable components should be seg-
regated and not allowed to intermix with nonreusable parts or parts from
other units. Delicate parts, which contain critical sealing surfaces, must
be protected and isolated from other parts to prevent damage during the
cleaning procedure.
4. Use only genuine Aqua Lung or Apeks parts for the service of this product.
DO NOT attempt to substitute an original part with another manufacturer’s,
regardless of any similarity in shape or size.
5. Do not attempt to reuse mandatory replacement parts under any circum-
stances, regardless of the amount of use the product has received since it
was manufactured or last serviced.
6. When reassembling, it is important to follow every torque
specication prescribed in this manual, using a calibrated torque wrench.
Most parts are made of either marine brass or plastic, and can be perma-
nently damaged by undue stress.
7. In order to make the product compatible with nitrox up to 40%
O2 (EAN40), the product must be properly cleaned, lubricated
and assembled using genuine Aqua Lung or Apeks replace-
ment parts. In addition, assembly must be carried out in a clean
environment using powderless, latex gloves or equivalent. For more detailed
information, be sure to read Procedure A: Cleaning and Lubricating.
GENERAL CONVENTIONS
Unless otherwise instructed, the following terminology and techniques
are assumed:
1. When instructed to remove, unscrew, or loosen a threaded part, turn
the part counter-clockwise.
2. When instructed to install, screw in, or tighten a threaded part, turn
the part clockwise.
3. When instructed to remove an o-ring, use the pinch method
(see illustration below) if possible, or use a brass or plastic o-ring removal
tool. Avoid using hardened steel picks, as they may damage the o-ring
sealing surface. All o-rings that are removed are discarded and replaced
with brand new o-rings.
4. The following acronyms are used throughout the manual: MP is Medium
Pressure; HP is High Pressure; LP is Low Pressure.
5. Numbers in parentheses reference the key numbers on the
exploded parts schematics. For example, in the statement,
“...remove the o-ring (7) from the crown (8)...”, the number 7 is
the key number to the crown o-ring.

23Install a new gasket (2) into the air cell manifold.
2Turn the collar (1) over and hold next to the manfold
of the air cell. Take note of the
12-sided placement notches on
the manifold and inside the col-
lar. These must align together
while tightening down the collar.
3Place the collar (1) over the manifold of the air cell.
Gently turn the collar to engage
the threads, taking care not to
cross-thread. Line up the ina-
tor assembly in the desired posi-
tion while tightening the collar by
hand until snug.
4Install a MP inator hose to a properly adjusted rst stage. At-
tach the rst stage to a cylinder lled to 3000 psi (206 bar). At-
tach the hose to the quick disconnect tting on the inator.
5Slowly open the cylinder valve and pressurize the
regulator, listen for any leaks.
There should be no leaking of
gas. If leakage occurs, deter-
mine the source and de-pres-
surize. Refer to Table 1: Trou-
bleshooting Guide.
CAUTION:Before pressurizing the rst stage, it is important
to have a properly adjusted second stage attached to the rst
stage. This will provide a safety relief valve if the MP exceeds
145 psi (10 bar). Failure to relieve increasing MP may result in
damage to the MP hose.
FINAL TESTING
1While holding the upper elbow (4) secure, rmly grasp the in- ator and pull it in a straight line directly away from the elbow.
Check both of the attachment points of the ribbed hose (12). Check
the ribbed hose for signs of damage or decay, if found you will need
to replace the ribbed hose before proceeding.
10

6Depress the inator but- ton several times to ensure
that airow is unobstructed, DO
NOT completely ll the air cell.
After releasing the button, listen
carefully to ensure that the air-
ow has completely stopped. If
airow continues, de-pressurize
and refer to Table 1: Trouble-
shooting Guide.
7Orally inate the air cell with several deep exhalations
to conrm air is entering the air
cell. If air is not owing into air
cell refer to Table 1: Trouble-
shooting Guide.
8Hold the inator button de- pressed to fully inate the
air cell until an over-pressure
relief valve opens to release the
excess pressure.
CAUTION:Before performing this test, conrm the aircell has
functioning over-pressure relief valves. Failure to do this could
cause permanent damage to the air cell that will require replace-
ment of the aircell.
NOTE: The WTX inator does not have a built in over-pressure
relief valve.
PSD/BC-1 Inator Only: Pull straight down on the inator to vent
air from the inator exhaust valve.
Conrm both methods will rapidly deate the air cell.
10With the air cell fully inated, listen for any
leaks. Submerge the entire in-
ator assembly in fresh water
and check for any bubbles. If a
leak is found, depressurize and
refer to Table 1: Troubleshoot-
ing Guide.
11 If leaks were not detect- ed, conrm the air cell
is fully inated. Disconnect the
MP inator hose from the quick
disconnect tting. Set a timer
for one hour to ensure there are
no leaks. If air loss occurs, de-
pressurize and refer to Table 1:
Troubleshooting Guide.
THIS CONCLUDES THE SERVICE
OF THE WTX INFLATOR
12If the air cell has begun to deate within one hour, fully in- ate the air cell once again and hold the entire unit com-
pletely submerged in fresh water for at least one minute to deter-
mine the source of the air loss. Carefully observe the inator for
any signs of bubble formation indicating a leak, especially around
the inator button, ribbed hose & manifold connection. If a leak is
found, refer to Table 1: Troubleshooting Guide.
9With the air cell fully inated, Press the oral button briey to vent air.

PROCEDURE A: CLEANING & LUBRICATING
Cleaning Brass and Stainless Steel Parts
1. Preclean in warm, soapy water* using a soft nylon bristle brush.
2. Thoroughly clean parts in an ultrasonic cleaner lled with soapy water. If there are stubborn deposits, household white distilled
vinegar (acetic acid) in an ultrasonic cleaner will work well. DO NOT place plastic, rubber, silicone or anodized aluminum parts
in vinegar.
3. Remove parts from the ultrasonic cleaner and rinse with fresh water. If tap water is extremely “hard,” place the parts in a bath
of distilled water to prevent any mineral residue. Agitate lightly, and allow to soak for 5-10 minutes. Remove and blow dry with
low pressure (25 psi) ltered air, and inspect closely to ensure proper cleaning and like-new condition.
Cleaning Anodized Aluminum, Plastic & Rubber Parts
Anodized aluminum parts and parts made of plastic or rubber, such as box bottoms, box tops, dust caps, etc., may be soaked and
cleaned in a solution of warm water mixed with mild dish soap. Use only a soft nylon toothbrush to scrub away any deposits. Rinse
in fresh water and thoroughly blow dry, using low pressure ltered air.
Cleaning MP Hoses (Air use Only)
Follow Hose Inspection & Cleaning Guidelines for more detailed information
1. Hose ttings: Ultrasonically clean with soapy water; Use soft nylon bristle brush. If corrosion is evident, use a brass bristle brush.
2. Run water through hose if needed
3. Thoroughly rinse with fresh water
4. Blow out hose before installing
Lubrication and Dressing
Wear powderless, latex gloves when handling and lubricating o-rings. Keeping internal parts free from skin oils and other contaminates
is important when running enriched air nitrox through a rst stage. All o-rings should be lubricated with Christo-Lube®M CG -111. D re ss
the o-rings with a very light lm of grease, and remove any visible excess by running the o-ring between thumb and forenger. Avoid
applying excessive amounts of Christo-Lube grease, as this will attract particulate matter that may cause damage to the o-ring.
*Soapy water is dened as “household” grade liquid dishwashing detergent diluted in warm water.
When it comes to issues of nitrox safety and compatibility, the concerns lie primarily with the regulator’s rst stage as it is subjected to
high inlet pressures. High inlet pressures lead to adiabatic compression or heating of the gas. The Aqua Lung or Apeks regulator product
described in this manual, when properly cleaned and assembled, is authorized for use with enriched air nitrox (EAN) that does not ex-
ceed 40% (EAN 40). It is authorized because it has undergone adiabatic compression testing and the authorized service kit components
and lubricants are compatible in elevated oxygen environments. During cleaning, a mild detergent must be used to remove condensed
hydrocarbons (compressor oils) from the inside passageways of the rst stage. For the rst stage to remain EAN40 compatible, only
use hyperltered compressed gas (hydrocarbons < 0.1 mg/m3). Ordinary compressed breathing air (Grade E) usually does not meet
this criterion. Once ordinary breathing air is used, the rst stage is no longer EAN40 compatible until it is cleaned and serviced again.
Although regulator second stage components are not exposed to high pressure EAN, Aqua Lung and Apeks recommend that the same
cleaning procedures be followed for the complete regulator. This prevents the possibility of cross contamination and guarantees the
cleanliness of the entire regulator.
AQUA LUNG AND APEKS REGULATORS AND NITROX
CAUTION: Do not place complete hose length in contact with acid solu-
tions. This could alter their physical properties and cause degradation
and premature breakdown.
CAUTION: Do not place plastic and rubber parts in contact with acid solu-
tions. This could alter their physical properties and cause degradation and
premature breakdown.
