1 INTRODUCTION
1.1 Sc op e a nd de finition s
This manual provides installation, operation and maintenance instructions for
the Edwards FL20K Foreline Trap. You mllst use the FL20K as described in this
manual.
Read this manua l before you install and operate the FL20K Important safety
information is highlighted
as WARNING and CAUTION ins t ruc tions; you
must obey these instructions. The use of WARNINGS and CAUTIONS is
defined below.
WARNI NG
Warnings are given where fail ure to observe the instruction could result in
injury
or death to people.
CAUTION
Cautions are given where failure to observe the instructi on could result in
damage to equip ment, associated equipment and process.
The units
used throughout this manual conform to the 51 internat ional system
of un its of measurement.
1.2 Ge n era l desc ription
The FL20K has been developed for use in clean pumping systems to prevent the
back-
migration of rotary pump oil vapou r into the systems; we particularly
recommend that you use an FL20K with two-stage r otary pumps.
The component partsoftheFL20K are illustrated inFi gure 1. The FL20K consists
of a metal basket (4) located within a cast alumin i um body (3), the metal basket
is secured in place by a knur l ed nut (1), lid (6) and spring (5).
FL20K Foreline Trap

A
sorbent is contained in the metalbasket to absorb any oil which back-migrates
from the
pump. The sorbent material u se d is activated alumina which has
exceptional
trapping properties for oil vapour. It has a l ong life (up to six
months) before
it becomes satu rat ed and has to be renewed.

3.1 U np ack a nd inspect
Remove all packing materials and check the FL20K. If the FL20K is damaged,
notify your supplier and carrier in writing within three days; state the Item
Number of the FL20K together with your order number and your supplier's
invoice number. Retain all packaging materials for inspection. Do not use the
FL20K if it is damaged.
Check that your package contains the items shown in Table L If an yone of these
items is missing, notify your supplier in writing within three days.

We recommend that you mount the FL20K horizontally, as sh own in Figure 1-
[f necessary, however, you can mount the FL20K in any orientation, as the
sorbent is secure ly retained in the basket. The mass of the FL20K will be
adequate ly supported by the pipeline connecti ons and you can connect either
port to the rotary vacuum pump. However, we recommend that you mount the
FL20K as close to the vacuum system and as far from the rotary pump as
possible, to
maximise the useful life of the sorbent. When you mount the FL20K,
ensure that you leave adequate clearance to enable the sorbent basket to be
removed.
Use standard KF coupling components (that is, NW clamping rings, centring
rings and '0' rings) to connect the FL20K to the pump and the vacuum system.

WARNING
Activated alumina is a desiccant and will absorb materials from your
process system. You must take suitable precautions to protect people from
the harmful effects of any noxious materials released if you bake the spent
alumina to reactivate it. Avoid inhalation of its dust, eye contact and
unnecessary skin contact.
CAUTION
Do not overfill the basket with sorbent. If you do, crushed sorbent could be
sucked into the rotary pump and damage the pump .
1. Refer to Figure 1; unscrew and remove the nut 0) and the lid (6).
2. Remove the basket (4) and spring (5) from the trap body (3).
3. Refer to Figure 3. Remove the wing nut (9) and end cap (1) from the basket
(3). Remove the washer (10), compression spring (8) and perforated end
disk (7).
4. Fill the basket wit h sorbant; when full, the end disk (7) should align with the
marker (6) on the spind l e:
• Fill the basket with alum i na balls so that the top of the sorbent charge is
approximately level with the marker (6).
• Tap the basket gently to settle the sorbent, then add more al umina balls
if necessary.
S. Place the perforated end disk (7) on top of the alumina ba ll s and slide the
spring (8) over the spindle (4) so that it rests on the end disk (7). Ensure that
both end disks (5, 7) have their smooth side in contact with the balls.
6. Refit t he washer (10) and end cap (1) over the spindle.
7. Refit thesecond washer (10) and wing nut (9) over the spindle (4) and tighten
the
wing nut (9). To ease tighteningof thewi ng nut, pus h the lid down gent l y.

4 OPERATION
WARNING
Activated alumina is a desiccant and will absorb materials from your
process system. You must take sui table precautions to protect people from
the harmful effects of any noxious materials released if you attempt to
reactivate spent al umina by baking. Avoid inhalation of its dust, eye
contact and unnecessary skin contact.
Take note of the following information:
• In common with other types of sorbent, activated al umina absorbs
moisture. This wi ll not affect its oil vapour trapping properties but may
tend to prolong rough
pumping on successive pumping cycles. Regular
regeneration by baking the trap or renewa l of th e sorbe nt will be
necessary for rapid pump-down.
• If the FL20K has been open to atmosphere for a l ong period of time, it
may be necessary to carry out prolonged pumping with a gas-ballasted
rotary
pump to remove absorbed moisture. Alternatively, remove the
basket from the FL20K
and bake it at 250°C to 300 °c for two hours.
• Use a valved by-pass line to minimise vapour absorp ti on during
pump-down .

WARNING
Activated
alumina is a desiccant and will absorb materials from your
process system. You must take suitable precautions to protect people from
the
harmfu l effects of any noxious materials released if you attemp t to
reacti
vate spent alumina by baking. Avoid inhalation of its dust, eye
contact
and unnecessary skin contact.
During normal use, the sarbent material nearest to the por t connected to the
rotary pump will become brown in colour. When the discolouration reaches the
sorbent layer furthest from the port, you must change the sorbent charge. The
time taken for this to occur depends on the frequency of use and the location of
the trap in re lation to the rotary pump. A typical charge life is six months,
although
we recommend that you change the charge every three months as a
routine maintenance
procedure
1. Refer to Figure 1. Unscrew and remove the nut (1) and the lid (6).
2. Remove the basket (4) and spring (5) from the trap body (3).
3. Refer to Figure 3. Remove the wing nut (9) and end cap (1) from the
basket
(3). Remove the washer (10), compression spring (8) and perforated
end disk (7).
4. If the trap body interior appears oily or dirty, wash it out with iso-propyl or
ethy l alcohol and then dry it thoroughly.
5. Fill the basket (3) with sorbent: refer to steps 4 to 9 ofSection 3.3.
