F. Place the
BODY (29)
into a padded vise and apply a modified 1” crows foot wrench or modified 1” yoke nut socket attached
to a calibrated torque wrench and torque the retainer assembly
to 23‐25 ft‐lbs (17‐18.4 N‐m)
(Fig. 25)
.
Fig. 25
CAUTION:
Insure
that
the
1”
modified
crows
foot
wrench
or
1”
modified
yoke
nut
socket
is
engaged
securely
over
the
DVT
Yoke
Retainer
to
prevent
marring
or
damage
to
the
part.
CAUTION: Tighten the vise only as needed to hold the first stage secure; DO NOT over tighten. Doing so will result in
deformation of the parts, rendering them unusable.
11. Lubricate and install all O‐RINGS onto all Hoses and
PORT PLUGS N/S
. Install all LP Hoses and
PORT PLUGS N/S
into the
BODY (21)
, and the HP Hose or
PORT PLUG N/S
into the
BODY (21)
, tightening clockwise with a 5/32" hex key socket
to a
torque of 35‐40 in/lbs (3.95‐4.5 N‐m)
.
CAUTION: Be certain not to install any low pressure Hose into the High Pressure Port via an Adaptor.
FINAL ADJUSTMENT AND TESTING
1.
Connect
a
recently
calibrated
Low
Pressure
Test
Gauge
to
a
low
pressure
Hose,
and
connect
the
First
Stage
with
Second
Stage
and
Low
Pressure
Test
Gauge
to
a
pure
breathing
gas
source
of
3000 PSI
(207 bar)
. Slowly open the supply valve to
pressurize the Regulator, and purge the Second Stage several times.
2. Adjust the intermediate pressure, if necessary, to read
140‐145 PSI
(9.7‐10 bar)
by adding and/or substituting
SHIMS (22)
to increase or decrease the pressure.
NOTE: Ensure that the intermediate pressure holds stable at 140‐145 PSI, and does not creep or
fluctuate after the Second Stage has been purged several times. If creeping is detected, refer to the
Troubleshooting Section on page 3 to determine possible cause and treatment.
