RS 193-5525 User manual

Please note: The portable filtration unit is supplied without
an element fitted. A choice of replacement
elements are available as separate items. See
section on element servicing for fitting
instructions.

Operation
A. Remove all shipping plugs from the hoses and fittings.
B. Ensure that a suitable element is fitted and that the element
housing cover is fitted with its ‘O’ ring and that the cover is
correctly screwed into place.
Excessive force is not required.
C. Ensure that the hoses are correctly fitted to the filter unit
(see Figure 1).
The inlet, or suction hose should be fitted to the port
nearest to the motor, marked with arrow
The outlet hose should be fitted to the port furthest from the
motor, marked with arrow
D. Connect the wand assemblies if required.
E. Place the inlet hose/wand assembly into the fluid to be
filtered and/or transferred. Place the outlet hose/wand
assembly into a suitable fluid discharge container.
F. Connect the filter unit to the appropriate power supply and
switch on the filter unit utilising the on/off switch at the rear
of the unit (Figure 1).
G. If, during operation the 1.7 bar differential visual indicator
(element condition monitor) Figure 1, moves into the red
area, switch off the unit and change the element. (See
element servicing section).
Please note: That if the filter unit is being used to pump fluid to
a height of more than 2 metres, the indicator may
move into the red area immediately. This is
caused by the extra pressure generated and
does not necessarily indicate that the element
needs changing.
H. Upon completion of the operation, switch the filter unit off
and disconnect from the power supply.
I. Withdraw the hoses from their respective fluid containers
and drain them into a waste fluid vessel. To ensure ‘No-
mess’ transportation, the inlet and outlet hose assemblies
can be screwed together by removing the wand assembly.
Element servicing
A. Switch off the filter unit and isolate from the power supply.
B. Rotate the element housing cover anti-clockwise and
remove.
C. Remove the dirty/contaminated element from the housing
and dispose of. (Elements are non-cleanable). Ensure
element housing is clean.
D. Place the new element in the housing, fitting the ‘O’ ring
seal into the lower location hole.
E. Inspect the housing cover ‘O’ ring and replace if necessary.
F. Replace the housing cover and hand-tighten.
Note: It is recommended the filter unit is cleaned and flushed
between uses.

Troubleshooting guide
Symptom Problem Solution
Does not start ON/OFF switch Turn switch on, replace if defective.
No electrical power Plug in the filter unit, check for tripped circuit breakers, check for
blown fuses.
Rectifier Replace if defective.
Motor overheated (77°C) Allow motor to cool, thermal overload will automatically reset.
Defective motor Replace motor.
Does not start or erratic Worn motor brushes Replace motor brushes.
motor noise
Intermittent start/stop High viscosity fluids High viscosity fluids can cause the motor to overheat and cycle
operation intermittently.
Worn motor brushes Replace motor brushes.
Defective motor Replace motor.
Hot motor Pumping under heavy load It is normal, under a heavy pumping load, for the motor to reach
71°C.
Defective motor Replace motor if the motor shell temperature reaches greater
than 77°C.
No flow or erratic Filter housing not filled with oil Allow the filter unit to run for a few seconds.
pump noise Suction leak Check tightness of inlet fittings and hoses. Check gaskets are in
place and are not damaged. Check for kinks or restrictions in the
inlet hose.
No suction Blocked strainer Clean or replace the inlet strainer as required.
Reduced oil flow High viscosity fluids High viscosity fluids can cause reduced flow, which is normal.
Element dirty Replace or clean element.
Relief valve sticks or lodged open Clean relief valve or replace if defective.
Partially obstructed inlet or Clear the hose obstruction.
outlet hose
Suction leak Check tightness of inlet fittings and hose.
Worn gears Replace gear set.

Obstructed outlet Clear outlet obstruction.
Defective indicator Replace indicator.

seem to move Defective indicator Replace indicator.
Hoses discolour or Fluid compatibility Certain fluids, over time, will cause the hoses to discolour. This
become rigid does not impair their, performance. But, some fluids will cause the
hoses to become brittle, requiring replacement.
Oil formation under Defective shaft seal Replace the motor shaft seal.
