DESICCANT DRYER
Care must be taken to change or regen-
erate the dryer desiccant material once
it appears pink in color. The following
steps are to be taken when recharging
the dryer:
1. Shut off air supply and bleed system.
2. Unscrew bowl ring and remove bowl
assembly.
3. Remove used desiccant.
4. Unscrew lead-in bullet from
threaded rod.
5. Remove exhaust tube, exhaust
element and gasket.
6. Inspect and clean inside of
exhaust tube if necessary and then
reassemble the main assembly.
7. Remove sight retainer and sight
O-ring.
8. Discard used desiccant within
the sight body.
9. Fill sight body with new or
regenerated desiccant.
10. Secure sight and O-ring by hand-
tightening sight dome retainer.
11. Fill bowl with new or regenerated
desiccant to 1/2" from top bowl
flange. Replace bowl assembly
and hand-tighten bowl ring.
Do not remove sight
retainer while bowl
is under pressure.
Store replacement desiccant in a dry
area making certain that the jar is
tightly sealed with a shelf life noted.
NOTE: To prevent excessive pressure
drop, it is recommended that the
exhaust element be replaced whenever
the desiccant is replaced or recharged.
FILTER/REGULATOR
FILTER
Filtration of dirt and foreign particles,
and the separation of moisture is auto-
matic with airflow. There are no moving
parts and no adjustments are neces-
sary. Accumulated sludge and moisture
should be drained off. Sediment should
not be permitted to fill above the lower
baffle.
Wash filter element at intervals with
naphtha to maintain filtering effi-
ciency. To clean element, depressurize
system, unscrew polycarbonate bowl,
and unscrew element from head. Dry
filter element thoroughly before reas-
sembling. Clean filter bowl(s) only with
soapy water. Inspect O-ring, replacing if
damaged or distorted. Reassemble with
care to avoid stripping threads on bowl.
After a metal bowl with sight is tight-
ened, it may be rotated up to 180°
for proper viewing.
REGULATOR
The regulator will accurately control
secondary pressure between 2 and
125 PSI. The self-bleed venting feature
permits use on dead-end applications.

After the regulator is installed, back
off pressure adjusting knob before the
air is turned on. Turn on the air supply
and regulate the adjusting knob until
pressure gauge shows the desired
pressure. To lock adjusting knob, push
down until knob snaps into locking
groove. To make regulator tamper-
resistant, remove adjusting knob from
unit. Regulator may be readjusted
by replacing knob.
IMPORTANT: Use care to avoid screwing
fittings too far into body of units as
it may close internal ports. Normally
finger tight plus one turn will seal.
TAMPER-RESISTANT OPTION
The tamper-resistant cap has been
provided in the plastic bag to ensure
that the reduced pressure cannot
be tampered with. To make the unit
"tamper-resistant", proceed as follows:
Turn the adjustment knob until the
desired reduced pressure is reached.
Remove the adjustment knob by pulling
upward. Install the tamper-resistant
cap in its place.
NOTE: To make permanently tamper-
resistant, LOCTITE the cap into place.
By permanently
loctiting the tamper-
resistant cap into place, the pressure
adjustment cannot be changed.
