MRF modification
Do not make any modifications (design modifications, extensions) to the MRF
without the prior consent of the manufacturer.
Immediately replace any unit components which are not in perfect condition.
Use only original spare parts (OEM).
Unpacking MRF
When receiving and unpacking the unit check it for damage in transit. Report any
damage to the forwarding agent immediately.
The connectors/ports are closed off so that no contamination can enter the unit
while it is in transit.
Dispose of the packaging material as appropriate for your area.
Storing the MRF
Store the filter in a clean, dry place.
Drain the filter housing completely before putting it into storage.
Check the external corrosion protection (paint coat) for damage, apply a new coat or
touch up the existing one as needed.
Wet the cleaned filter interior and all sealing surfaces such as the flange with a
suitable corrosion inhibitor, e.g. ANTICORIT 3 by Fuchs-DEA.
Storage temperature: +5°C to +30°C
Humidity: up to 50% relative humidity

MRFD4 Checking the Scope of Delivery
Checking the Scope of Delivery
Upon receiving the MRF check it for any damage in transit. Do not put the MRF into
operation unless it is in perfect condition. Report any damages in transit to the
transport company or the responsible agent immediately. Do not put the unit into
operation.

HYDAC FILTER SYSTEMS GMBH en Page 13 / 36
BeWa MRFD4 3342322a us 2010-05-20.doc 2010-05-20
Technical Description
The MultiRheo Filter MRF is a stationary filtration unit used for full-flow and bypass
filtration of low-viscosity fluids for the separation of particles of 100 ... 1 µm
(absolute).
The MultiRheo Filter is part of a filter series for the use of Flexmicron filter elements.
Restrictions pertaining to use
CAUTION
Impermissible operating media
The filter will be damaged.
►The unit is only to be used with mineral oils or mineral oil-based raffinates or
for cooling lubricants.

MRFD4 Calculating the pressure differential of the filter housing / filter element
Calculating the pressure differential of the filter housing / filter
element
The total pressure of the filters at a specific flow rate is comprised of the housing
and the filter element . The pressure loss of the housing can be determined
using the following pressure loss curve. The pressure loss of the filter elements is
computed on the basis of the R factors.
pp
Housing : Pressure loss curve, housing
p
Differential pressure (bar)
Flow rate (l/min)
The upper housing curve holds for mineral oil with a density of 0.86 kg/dm³ and a
kinematics viscosity of 30 mm²/s. The lower housing curve holds for water at 20°C.
For turbulent flow, the differential pressure will change proportionally to the density;
for laminar flow, it will change proportionally to the density and viscosity. The flow
velocity should not exceed 3 m/s at the filter inlet for oil and 4 m/s for water.

HYDAC FILTER SYSTEMS GMBH en Page 20 / 36
BeWa MRFD4 3342322a us 2010-05-20.doc 2010-05-20
Setting up / fastening MRF
Place the MultiRheo Filter on a flat horizontal surface that has a sufficient load-
carrying capacity and resilience.
Make sure to leave sufficient room, at least 1 m, over the filter housing to change
the filter element.
Fasten the filter with 6 suitable floor anchors.
Hydraulic connection of the MRF
Connect the MRF hydraulically using a flexible hose connection or pipeline.
Make sure that no vibrations and/or stress from other machinery and equipment are
carried over to filter housing.
Use expansion joints if necessary.
