DISASSEMBLY PROCEDURES
NOTE: Before performing any disassembly, refer to the exploded
parts drawing, which references all mandatory replacement parts.
These parts should be replaced with new, 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 plastic or brass o-ring removal tool
(PN 944022) 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 with new. DO NOT use a dental pick or any other
steel instrument.
Dry Swivel Turret (DST) First Stage Disassembly
1
Using the appropriate sized open end wrench, remove all the
hoses from the first stage body. Using the o-ring removal tool (PN
944022) remove the o-ring from the male end of the hose and discard.
2
Using a 5mm hex key,
remove a single HP
blanking plug (19).
3
Install vice mounting tool
(PN 100395) into the open
HP port.
WARNING: If using a CO2 cartridge instead of PN 100396,
ensure that it has been discharged prior to use.
CAUTION: If using a CO2 cartridge, thread an HP port
adapter (PN 101785) onto the end. This will prevent the
threads from breaking off in the first stage.
4
Secure the vise mounting
tool and first stage into
a bench vise adapter (PN
100398) or vise.
5
Insert the Apeks pin spanner (PN AT30) into the hole
of the environmental end cap (26). Ensure that the pin
spanner is sitting flush to avoid damage to the end cap. Turn
the environmental end cap counter-clockwise to remove from
the diaphragm clamp (21). Remove and discard the hydrostatic
diaphragm (25).
6
Turn the first stage over
to remove the hydrostatic
transmitter (23) from the
first stage.
7
Use the pin spanner to turn the diaphragm clamp (21) counter-
clockwise to loosen. Remove from vise and continue to
unscrew the diaphragm clamp by hand. The spring (1) and spring
carrier (2) will come out once the diaphragm clamp is removed.
CAUTION: The spring and spring carrier will come out
once the diaphragm clamp is completely removed. Ensure
the first stage is over a workbench when removing the
diaphragm clamp to avoid losing or damaging parts.
