INSTALLATION & MAINTENANCE MANUAL
Recommended Routine or Periodic Maintenance for all
FP
Model Fuel Purifiers
I.
The liquid purged from the purifier is a hazardous
waste and must be disposed of in accordance with
all state and local ordinances.
II.
Although there may be operational instances
where it is desirable, from a safety standpoint, we
recommend the engine be stopped and the
ignition or pump be turned off before purging the
purifier.
III.
It is NOT necessary to drain the entire unit, except
under
“V” below.
A.
Only contamination should be removed.
B.
Purging is complete when clean fuel is
observed draining from the purifier.
IV.
The purging procedures explained in “VI” below,
are recommended to be performed every 100 to
150 operating hours. Purifiers operating in harsh
environmental conditions, i.e., high humidity, dust,
etc., or those cleaning seriously contaminated
fuel, or operating in fuel cleaning or polishing
operations will require more frequent purging.
V.
We recommend draining the purifier and removal
of the top fill plug and drain valve after every 2,000
hours of operation. When the top and bottom
plugs are removed, the purifier can be blown out
with high-pressure air from the top down. This will
remove any solids that may be retained in the
baffles or lower portions of the purifier.
VI.
Purging
A.
Purifier operating on the pressure side of
the fuel system:
1.
Open drain valve located at the bottom
of the purifier. Purge or drain
contaminants until clean fuel is
observed.
2.
Close drain valve. Pressurize fuel
system.
3.
Press air purge valve located on the top
of the unit. Hold valve down until all air
has been evacuated and fuel squirts
from the valve.
4.
Purifier is ready to resume operation.
B.
Purifier operating on the suction side of the
fuel system:
1.
If unit is equipped with a check valve
located at the intake coupling:
a.
Open drain valve located at the
bottom of the purifier. Purge or drain
contaminants until clean fuel is
observed.
b.
Close drain valve.
c.
Remove fill plug at the top of purifier
and top off fuel level in unit.
d.
Purifier is ready to resume operation.
2.
If unit is equipped with a fuel shut-off valve:
a.
Shut off fuel flow to purifier.
b.
Using a bottle, a jar, or a similar
container, open the drain valve
(located at the bottom of the purifier).
Purge or drain contaminants until
clean fuel is observed. We suggest
you open and close the drain valve
several times in a rapid succession to
ensure all contaminants have been
removed and the drain is sealed.
c.
Remove fill plug at top of purifier and
top off fuel level in unit.
d.
Purifier is ready to resume operation.
3.
If no shut-off or check valve is provided:
a.
Using a bottle, a jar, or a similar
container, open the drain valve
(located at the bottom of the purifier).
Purge or drain contaminants until
clean fuel is observed. We suggest
you open and close the drain valve
several times in a rapid succession to
ensure all contaminants have been
removed and the drain is sealed.
b.
Remove fill plug at top of purifier and
top off fuel level in unit.
c.
Purifier is ready to resume operation.
d.
Restart system, run for a minute or so,
shut down and repeat Step “B” above
to ensure the purifier has remained
full.
NOTE: In some installations, especially if the
purifier is located on the suction or vacuum side
of the fuel system, fuel may drain back into the
tank whenever the top fill plug is opened. If a
check valve or shut off valve cannot be
installed at the “IN” port of the purifier, it may
be helpful to install the incoming line so that a
loop extends above the level of the top of the
purifier (so that the fuel line creates a reverse
“P” trap). Where possible, pinching off the fuel
line prior to opening the top fill plug will also
help to ensure the fuel does not drain back into
the tank.
