Assembly
1) Install hoses to inlet and outlet
filters by threading the hose end
with the straight thread “o”-ring seal
fitting into the filter flange.
2) Connect the PVC tube wands to
the swivel fitting on the hose end.
Whenever servicing the PVC tube
wand
do not overtorque the metal
fittings going into the PVC coupling.
Overtorque will result in cracking
the coupling. Generally, 1/4 turn
beyond handtight is sufficient.
Operating Instructions
1) Insert the inlet wand assembly
into the supply fluid receptacle
(drum/reservoir). The “RF". filter is
the inlet filter.
2) Insert the outlet wand assembly
into the clean fluid receptacle
(drum/reservoir). The “CF” fIlter
is the outlet filter.
Caution:
Do not kink the hose assemblies,
this may result in excessive
vacuum or pressure at the pump.
3) Verify that the ON/OFF switch is
OFF and plug the cord into a 115V
10A grounded outlet (3 wire).
4) Turn switch to ON position and
check outlet wand for oil flow.
Allow 30 to 60 seconds for filters to
fill with oil. If repeated attempts to
obtain oil flow fail, check pump inlet
fittings for tightness, remove inlet
filter access cover and verify the
cover sealing “o”-ring is in place.
For very viscous fluids it may be
necessary to pour 1 or 2 quarts of
fluid into the “RF” inlet filter housing
to prime pump initially.
5) The condition of the filter ele-
ment should be monitored by
observing the cleanliness indicator
on the discharge filter. When the
Indicator is in the CHANGE posi-
tion, both inlet and outlet filter
elements MUST be replaced to
prevent fluid from going into
bypass in the filters.
6) The inlet filter Is provided with
a 3PSI bypass spring, and
prevents the pump from cavitat-
ing If the element is not
changed. The outlet filter is
provided with a 25PSl bypass
spring to prevent excessive
pressure which may be harmful
to personnel or to the filter cart.
Warning:
The filter bypass spring acts as a
relief valve for the pump. Do not
restrict the discharge hose with
a shut-off valve which will defeat
the function of the bypass valve,
causing excessive pressure,
which may be harmful to person-
nel or to the filter cart.
7) The cleanliness indicator
works on differential pressure
and will indicate the condition of
the element (CLEAN, CHANGE,
or BYPASS).
NOTE:
The filter cart must be in
operation for the indicator
to read properly.
Maintenance
Instructions
1) Turn switch to OFF position and
unplug cord from electrical outlet.
2) Remove tube wands from oil to
prevent siphoning.
3) Loosen hex head screws on
filter cover. Turn cover to clear
screws, remove cover.
4) Pull flow diverter assembly from
the filter head. Filter element will
follow the diverter.
a) Replace the cellulose,
synthetic or Microglass II
elements. Verify replacement.
b) Wire mesh elements can be
cleaned. Ultrasonic cleaners
provide best results.
5) Install element on flow diverter
and reinstall in filter housing. Make
sure diverter “o"-rings seat
properly into the head.
6) Check to be sure that the notch
on the flow diverter lines up with
the notch in the head.
7) Inspect the cover “o"-ring and
replace if necessary.
8) Replace cover and tighten hex
head screws until they are snug.
Do not over-torque these screws.
Do not interchange the inlet filter
cover with the outlet filter cover.
(The inlet filter has a “RF” prefix,
the outlet filter has a "CF" prefix).
