Copyright ©2000 Aqua Lung America, Inc.
Introduction
This manual provides factory prescribed proce-
dures for the service and repair of the Cousteau/
SEA first stage regulator. It is not intended to be
used as an instructional manual for untrained person-
nel. The procedures outlined within this manual are
to be performed only by personnel who have re-
ceived factory authorized training through an Aqua
Lung Service & Repair Seminar.
If you do not completely understand all of the
procedures outlined in this manual, contact Aqua

before proceeding any further.
Warnings, Cautions, & Notes
Pay special attention to information provided in
warnings, cautions, and notes that are accompanied
by one of these symbols:
A WARNING indicates a procedure or situation
that may result in serious injury or death if
instructions are not followed correctly.
A CAUTION indicates any situation or tech-
nique that will result in potential damage to the
product, or render the product unsafe if in-
structions are not followed correctly.
A NOTE is used to emphasize important

Scheduled Service
Regulators should be given the same care and
maintenance as life support equipment. It is there-
fore important to perform scheduled overhaul service
for the Cousteau/ SEA, complete with second stages,
according to the procedures outlined in this manual;
at least once a year with normal or infrequent use.
NOTE: A unit that receives heavy or frequent
use, such as in rental, instruction, or commer-
cial applications, should be serviced at least
twice each year - or more often - depending on
the conditions of use and the manner in which
it is maintained. (Refer to the care and mainte-
nance procedures outlined in the Regulator
Owner’s Manual.)
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 or
service the Cousteau/ SEA first stage, 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 specifically set up and equipped for
the task. Adequate lighting, cleanliness, and
easy access to all required tools are essential for
maintaining a professional repair facility.
3.
Before beginning any disassembly, it is impor-
tant to first perform the Initial Inspection proce-
dure, and refer to Table 1 - Troubleshooting to
determine the possible cause of any symptoms
which may be present.
4.
As each individual regulator is disassembled,
reusable components should be segregated to
prevent them from mixing with non-reusable
parts or parts from other regulators. Delicate
parts, and those which contain critical sealing
surfaces, must be protected and isolated from
other parts to prevent damage during the clean-
ing procedure.
5.
Use only genuine Aqua Lung parts purchased
directly from Aqua Lung when servicing any
Aqua Lung product. Substitution with another
manufacturer’s parts constitutes an after-market
modification of the product, and renders the
original warranty null and void.
6.
Do not attempt to reuse mandatory replacement
parts under any circumstances, regardless of the
amount of use the product has received since it
was manufactured or last serviced.
7.
When reassembling, it is important to follow
every torque specification prescribed in this
manual, using a quality torque wrench. Most
parts are made of either marine brass or plastic,
and can be permanently damaged by undue
stress caused by overtightening.
