DISaSSEMBLy pROCEDuRE

Note: Before performing any disassembly, refer to the exploded
parts drawing, which references all mandatory replacement parts.
These parts should be replaced and must not be reused under
any circumstances – regardless of the age of the regulator or how
much use it has received since it was last serviced.
CauTION: use only a brass o-ring removal tool (pN 944022)
or plastic (pN 103102) when removing o-rings to prevent
damage to the sealing surface. Even a small scratch across
an o-ring sealing surface could result in leakage. Once an
o-ring sealing surface has been damaged, the part must
be replaced. DO NOT use a dental pick or any other steel
instrument, except where instructed.
Note: The Conshelf XIV Tool Kit (PN 108110) has all the tools re-
quired for maintenance of all the Conshelf XIV configurations. The
Conshelf XIV Tool Kit is described on pg. 33 of this manual.

First Stage Disassembly

1
Using a 9/16" open end wrench, turn the wrench counterclockwise
and remove the MP hose (26) from the first stage body (16). If
installed, remove the HP gauge hose with a 5/8" open end wrench
and, the MP inflator hose with a 9/16" open end wrench. Remove HP
port plug with a 5/32" hex key or any remaining MP port plugs with
a 1/2" open end wrench or socket.
2
Remove the 2nd stage from the regulator by holding the inlet
fitting (11) with a 3/4" open end wrench, use an 11/16" open end
wrench to unscrew the swivel counterclockwise from the regulator
and remove the swivel end of the MP hose from the 2nd stage.
3
Remove and discard the o-rings (25 & 27) from the MP hose.
4
If the HP hose of the pressure gauge requires the use of the HP
adapter (22), remove the adapter by turning it counterclockwise, us-
ing an 11/16" wrench. Remove and discard the adapter o-ring (21).
5
Remove and discard all o-rings of the MP inflator and/or the HP
hose of the pressure gauge.
CauTION: NEVER attempt to secure the first stage body by
direct clamping in a vise. This will result in damage to the
regulator body requiring replacement of this part.
CauTION: Empty CO2 cartridge used for vise mounting should
not be an old rusty cartridge from a Buoyancy Control Device.
A new cartridge should be placed in a CO2 firing mechanism
and discharged.
