GENERAL DESCRIPTION
The Velcon that you have received consists of the vessel,
filter elements, and accessory equipment to meet your
specific requirements. Descriptive literature covering the
accessories is included near the back of this manual.
A Velcon is specifically designed to remove solid
contaminants from the product being filtered. The product
enters from the inlet nozzle, rising vertically behind a baffle
until it reaches the region above the top of the highest
elements. The elements are arranged in vertical stacks
rising up from a flat division plate. The fluid enters the
outside of each element and flows toward the center of the
element. The flow then goes downward to the outlet.
Velcon are manufactured to meet a variety of different end
uses and specifications. The finest workmanship has gone
into the building of this Velcon. It is of no value, however, if
elements are improperly installed or the unit is improperly
operated. We urge you to read the manual carefully and
follow the instructions given.
NOTE Velcon has qualified the FO-6xxA3 pleated
media filter cartridges to EI Specification 1590,
“Specifications and Qualification Procedures for
Aviation Fuel Microfilters.”
INSTALLATION OF VESSEL
1. Identify the Filter inlet and outlet by the markings
provided on the vessel piping. The Filter must be
installed in the correct direction of ow to perform
properly and to avoid damage to the system.
2. INLET and OUTLET PIPING should be carefully
aligned to avoid stressing the Filter connections
during installation. Installation of shut-off valves on
either side of the Filter is recommended so that it
can be independently drained for cartridge change
or inspection.
CAUTION
STEPS 3 AND 4 SHOULD BE
PERFORMED BEFORE REMOV-
ING HINGE OR PIVOT MOUNTED
COVER TO ENSURE STABILITY OF
THE FILTER.
3. Bolt the lter to a stable base.
4. Carefully install correct gaskets on the inlet and
outlet connections and connect to the inlet and
outlet piping.
5. Connect any accessories that are not already
installed. See Accessory Parts List and literature
as required.
6. Cartridges are normally packed separately.
Open the vessel cover and install cartridges as
explained on page 8 and as per enclosed element
stack drawing. Tighten nuts on tie rods until the
rubber washers begin to curl. Do not over-torque.
sequence.
7. Be sure the cover gasket is in place and properly
aligned. Replace cover and secure tightly.
NOTE FILTERS MUST BE PROVIDED WITH
PRESSURE RELIEF VALVES IF THE
SYSTEM HAS POSITIVE DISPLACEMENT
PUMPS UPSTREAM OR AUTOMATIC
SHUT-OFF VALVES DOWNSTREAM OF
THE VESSEL.
START UP PROCEDURE
If the Velcon Filter has the accessories listed below, they
should be placed in the following positions:
1. Manual drain valves closed.
2. Manual air eliminator valve open.
3. The valves in the inlet and outlet piping should be
closed.
4. The pressure gauge valve to OFF position. For
Filters equipped with selector valves, this is done
by turning the handle outward so that the arrow
points toward the vessel.
For information on operation of accessories, turn to
Accessory Instructions in the back of the manual.
After the valves have been positioned as outlined, the unit
is ready to be filled.
The following operating instructions can be used for initial
start-up and for subsequent start-ups after installation of
replacement elements or servicing of the unit.
1. Start the system pump.
2. Slightly open the inlet valve, allowing the Filter to
slowly ll with uid. (Take about 10 – 15 minutes
to ll the vessel to eliminate the possibility of an
internal re.)
3. If the unit is equipped with a manual air eliminator
valve, leave the valve cracked open until the uid
ows from the opening; then close quickly.
4. If equipped with an automatic air eliminator, the
unit is lled when the air eliminator stops owing
air. When the Velcon Filter is lled with uid, slowly
open the valve on the inlet line, then slowly open

the valve on the outlet line.
5. When the unit is in operation, open the pressure
gauge, take a differential pressure reading and
record the reading. If there is no pressure differen-
tial, the system should be shut down and the Filter
inspected for broken seals or possibly elements left
out. See Differential Pressure Readings on Page 5
OPERATING INFORMATION
Below are the Velcon recommendations for operating
procedures. Your Company Maintenance and/or Quality
Control procedures may provide alternate instructions on
these matters.
1. FILTER CARTRIDGES should be changed in accor-
dance with one of the following (whichever comes
rst):
A. When the differential pressure reaches the level
specied on the cover page of this manual.
For Filters equipped with differential pressure
gauges, see paragraph 2 below.
B. When the ow rate is reduced to an unaccept-
able level because the cartridges are plugged
with contaminant.
C. Whenever efuent product is unacceptably
contaminated.
2. DIFFERENTIAL PRESSURE READINGS Differential
pressure is the difference between the pressure
upstream and downstream of the Filter. Differential
pressure increases when contaminant is ltered by
the lter cartridges and causes ow restriction.
Readings should be taken when the system
is owing at maximum capacity. If the Filter is
equipped with a direct reading differential pressure
gauge, the reading shown on the gauge is the dif-
ferential pressure across the Filter.
If the Filter is equipped with a pressure gauge and
a selector valve, use the following procedure for
determining differential pressure:
A. Turn the handle one way and record the pres-
sure reading.
B. Turn the handle the other way (90° or 180°,
depending on the type of valve) and record the
pressure reading.
C. Subtract the lower reading from the higher
reading to determine differential pressure. (The
higher reading is inlet pressure.)
If the lter/separator is equipped with a pressure
gauge and a selector valve, use the following
procedure for determining differential pressure:
A. Turn the handle one way and record the
pressure reading.
B. Turn the handle the other way (90° or 180°,
depending on the type of valve) and record the
pressure reading.
C. Subtract the lower reading from the higher
reading to determine differential pressure. The
higher reading is inlet pressure.
Differential pressure readings should be taken at
least once during every operating week and more
frequently in high throughput installations or when
the differential is increasing rapidly. Records of
the differential pressure and throughput should be
maintained to determine when cartridges should
be changed.
A sudden drop in pressure differential is an indica-
tion of a possible problem. Check rst to be sure
that readings were taken at equivalent ow rates.
If so, shut the system down, open the Filter, and
inspect for the following:
A. Collapsed or ruptured cartridges caused by
severe pressure differential or shocks in excess
of design limits.
B. Ruptured seals. Check to see that all O-ring
seals and gaskets seals are in place and have
the same alignment as when the elements and
parts were installed.
C. Broken end plates. Inspect all of the end plates
of the elements.
D. If any of the above are observed, check the
system for possible hydraulic shock condi-
tions. If the system is not provided with ad-
equate surge controls, the sudden start-up of a
high-pressure pump can create extremely high
shock
CARTRIDGE CHANGE OR INSPECTION PROCEDURE
A. Shut off the pump.
B. Close the inlet and outlet pipe valves.
C. Open the drain valves and remove the product
from the Filter.
D. Open the manual air eliminator valve. This will
permit the unit to drain faster.

F. Completely drain lter chamber.
G. Remove spent cartridges for cartridge change.
H. Wipe off or wash down any foreign matter from
the vessel interior.
I. Install the cartridges in accordance with in-
structions on page 8.
J. Tighten nuts on tie rods until the rubber wash-
ers begin to curl. Do not over-torque.
K. Check the cover gasket for alignment, re-
place the cover and secure tightly. The Filter
is now ready for the start-up procedure.SUMP

Installation Instruction for Open-End Filter Cartridges
1. Turn off pump. Close inlet and outlet valves and
open drain valve. Open the air eliminator or manual
bleed valve and drain the vessel.
2. Open vessel after making sure the vessel is com-
pletely drained.
3. Jack-up head and swing aside. Remove the spider
(if installed). Remove nuts and washers, endcaps,
old cartridges, and center plates, if any.
4. Wipe vessel clean whenever possible or ush.
5. Place cartridge over the center rod making sure
the cartridge is centered over the guide bar or
mounting adapter attached to the deck plate. The
cartridge must be seated at against the adapter
or deck plate.
6. For vessels with stacked cartridges, place the rst
tier of lter cartridges in position at all bulkhead
ports (per step 6). Insert center plate onto center
rod and insert into each cartridge. Next, install the
second tier of cartridges over the center plates.
There must always be a center plate between
every two stacked cartridges. Be sure the circular
guide on both sides of the center plate projects
into each cartridge.
7. When all cartridges are loaded, insert sealing cap
over center rod.
8. Install rubber washer, at washer, lock washer, and
nut in that order, onto each center rod. Tighten to 4
to 5 foot pounds of torque. (DO NOT TOUCH THE
OUTER FILTER MEDIA.)
9. Replace the spider as follows (if spider is not in-
cluded proceed to step #10):
Install the flat washer over each cartridge end and
install the spider over the ends of the cartridges.
Affix the spider to the threaded clips on the vessel
walls using the nut and lockwasher.
Adjust the spider clip nuts, so the spider lies flat on
the ends of the cartridges
Install the washer and nut over the ends of the
cartridges, to affix the spider to the cartridge ends.
Snug the nuts. DO NOT TIGHTENYET.
Adjust the ends of each cartridge to create even
separation between the cartridges and between the
cartridge and vessel wall.Cartridges should NOT
be touching each other, nor touching the vessel
wall.The ends of the cartridges can be shifted
within the spider plate holes as follows:
Cartridge
Length Shift Within the Spider Hole
Greater than
33"
Full movement within the spider
hole
30" Less than 5/8" (16 mm)
28" Less than 9/16" (14 mm)
24" Less than 1/2" (12 mm)
22" Less than 1/2" (12 mm)
20" Less than 3/8" (10 mm)
18" Less than 3/8" (10 mm)
16" Less than 1/4" (8 mm)
14" Less than 1/4" (6 mm)
11" Less than 1/4" (5 mm)
9" Less than 3/16" (5 mm)
When the cartridges are spaced properly, tighten
the spider nuts to 5 ft-lbs.
10. Inspect the cover gasket and replace it if neces-
sary. Tighten the cover securely in a cross-pattern
process.
11. Close the drain valve and start the system pump.
12. With the outlet valve closed, slightly open the inlet
valve and allow the vessel to ll SLOWLY with fuel
until the air eliminator closes or uid begins to ow
from the manual air vent. Close the vent valve.
Fully open the inlet valve.
13. Open the outlet valve SLOWLY.
14. When the unit is operating, check the differential
pressure across the cartridges. There should be
indication of positive pressure, normally 1-5 psid.
This insures that all seals have been properly made
during the installation.

Torque Requirements for Vessels with “O-Ring Closure”
Bolted pressure vessel closures operate on the premise that
the joint is clamped closed with a force sufficient to resist
the internal pressure yet still maintain a seal. The clamping
force, or pre-load, is applied by the closure bolts and its
magnitude is controlled by the torque applied. Application
of the correct preload is essential to maintaining a
positive seal and avoiding closure failures from fatigue or
overstressed vessel components.
The short term, and most obvious effect of grossly under-
torqued bolts is insufficient clamping force resulting
in a leaking closure. A more ominous result of under-
torqued bolts in systems which see a great number of
pressure cycles (such as refuelers, loading racks etc.), is
bolt fatigue failure. Repeated applications of stress to the
bolt eventually create a small crack at the surface of the
bolt which continues to grow until the bolt breaks and the
closure fails.
It is a good idea to re-torque the closure bolts after they
have been in use for a month or so to ensure the joint has
not “relaxed” and the preload reduced.
Over-torquing closure bolts will result in breaking or
bending vessel bolt clips or actually breaking the bolt
itself. Table One lists guideline torque values for lubricated
bolts for common sizes used for vessel closures. Always
use lubricated bolts, as this reduces the required torque,
improves torque accuracy, and retards corrosion.
A common cause of inaccurate bolt torque is inappropriate
bolt torquing procedures. Key elements to the procedure
are application of the torque in stages and in a specific
cross-torquing sequence. For most applications, torque
is applied to all bolts to 30% of full torque, then to all bolts
to 60% of full torque, and finally to all bolts to 100% of full
torque. Each torquing cycle is carried out in the applicable
cross-torquing sequence. Torquing sequences vary with
the number of bolts on the cover.
The tightening pattern is as follows: Tighten two bolts
diametrically opposite from each other, then tighten a
second pair of bolts diametrically opposite each other,
approximately 90 degrees away from the first pair, and so
on until all bolts have been tightened.
Using a clock as an example, the sequence would be: 12 - 6,
9 - 3, 11 - 5, 10 - 4, 7 - 1, and 8 - 2.
On large vessels, the cross-torquing process is tedious
but the addition of a second operator applying torque
improves the situation vastly.
Correct closure torquing will result in many years of
trouble-free vessel operation. Occasional inspections
for bolt cracks or clip damage is good practice to detect
possible closure problems before they occur.
