Conshelf XIV Service Manual
INTRODUCTION
This manual provides factory prescribed procedures for the
correct service and repair of the Aqua Lung Conshel XIV
regulator. 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 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.

SCHEDULED SERVICE
If the regulator is subjected to less than 50 dives per year, it is
permissible to overhaul it every other year with an inspection
procedure being performed on the "off" years. For example:
Year #1: Inspection; Year #2: Overhaul; Year #3: Inspection
Year #4: Overhaul, and so on.
Both Inspections and Overhauls need to be documented in
the Annual Service & Inspection Record in the back of the
Owner's Manual to keep the Limited Lifetime Warranty in ef-
fect.
If a regulator is subjected to more than 50 dives per year, it
should receive the complete overhaul.
An Official Inspection consists of:
1.
A pressurized immersion test of the entire unit to check
for air leakage.
2.
Checking for stable intermediate pressure that is within
the acceptable range.
3.
Checking for opening effort that is within the acceptable
range.
4.
A visual inspection of the filter for debris or discoloration.
5.
A visual inspection of the exhaust valve to see that it
is in good shape and that it's resting against a clean
surface.
6.
A visual inspection of the mouthpiece looking for tears
or holes.
7.
Pulling back hose protectors and checking that the
hoses are secure in the hose crimps.
If a regulator fails item #1,2,3 or 4 the entire regulator should
be overhauled. If a regulator fails 4,5,6 or 7 it will be up to
the technician's discretion whether or not a full overhaul is
required.
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 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 an efficient repair facility.
3.
The regulator body will need to be secured in a vise
when removing the spring retainer (28). NEVER SE-
CURE THE REGULATOR BODY DIRECTLY IN A VISE.
Instead, install a vise mounting tool (PN 100395) into
the high pressure port, then secure the vise mounting
tool in the vise. If you do not have a vise mounting tool,
use an EXPIRED CO
sure adapter (³₈" female to ⁷₁₆" male). Never screw a
CO
directly into a low pressure port in case the neck of
2
the CO
cartridge breaks off, leaving the threads stuck
2
in the regulator.
3.
As the regulator is disassembled, reusable components
should be segregated and not allowed to intermix with
nonreusable parts or parts from other units. Delicate
parts, including inlet fittings and crowns 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 parts provided in the over-
haul parts kit. DO NOT attempt to substitute an Aqua
Lung part with another manufacturer's, regardless of any
similarity in shape or size.
