4 | Transporting/storing the filter unit HYDAC FILTER SYSTEMS GMBH


4 Transporting/storing the filter unitFully empty the filter unit before transporting it or putting it intostorage. Remove the used filter element and dispose of it in anenvironmentally friendly manner. Clean the inside of the filterhousing.

NOTICEImproper clamping of the filter unit

The filter unit will be damaged.

u Clamp the filter unit while transporting only via the filterhousing.

Transport the filter unit only in standing position.

Fig. 11: Transporting the OF5 S/N

Store the filter unit in a standing position in clean and dryrooms. The conditions required for storage are given in chapterTechnical Data.

HYDAC FILTER SYSTEMS GMBH Setting up / assembly / integration of the filter unit | 5


5 Setting up / assembly / integration of the filter unitObserve the following notices for mounting the filter unit.

– Place the filter unit horizontally on a stable, even and hori-zontal surface.

– Press the brakes on the rollers, if available.

– Make sure that there is sufficient space above the filterhousing to replace the filter elements.

– Observe the maximum permissible ambient temperatureand constant supply of cooling air to avoid overheating.

– Make sure that there is sufficient space above the filterhousing to replace the filter elements.

– Install the shut-off valves in the flow pipe and return pipeduring assembly under the fluid level.

– Fasten the filter unit to the ground with four screws.

5 | Setting up / assembly / integration of the filter unit HYDAC FILTER SYSTEMS GMBH


5.1 Avoiding siphoningIf there is a height difference (ΔH) between the suction sideand pressure side container/system, the lower line can developa suction effect and trigger the siphoning effect between thecommunicating containers/systems. This siphoning effect alsooccurs when fluid is pumped in a pre-pressurized reservoir.

Fig. 12: Avoiding siphoning

NOTICESiphoning effect

Reservoir overflowing/leaking = oil spill

u Remove the ends of the hoses from the reservoir after op-eration or shut the shut-off device in the suction line.

After the filter unit is switched off, the height difference/primarypressure can cause flow to occur both in the feed direction andagainst the feed direction and the fluid can leak uncontrollably.



5.2 Measure or display dynamic pressure / differentialpressureIf pressure is measured in a hydraulic system, the type of mea-surement such as dynamic pressure or differential pressure as well as the measurement point is critical, as shown in thefollowing diagram.

Fig. 13: Measure or display dynamic pressure / differential pressure

∑p = Total of the pressures∆p1 = Differential pressure p1 = Back-pressure∆p2 = Differential pressure p2 = Back-pressure∆p3 = Differential pressure p3 = Back-pressure∆p4 = Differential pressure p4 = Back-pressure

In the example, the back pressure at the first measurementpoint shows the total of the subsequent pressures in the hy-draulic system.



5.3 Avoiding the mixing of oils - Emptying the filter unitIf you want to use the same oil for operation as in the previousoperation, it is not serious if the oils are mixed.

If you do not know which oil was previously filtered with the fil-ter unit, replace the filter element and empty the filter unit com-pletely in order to prevent mixing with the residual oil in the fil-ter unit.

If different oils are mixed, the oil properties can change as fol-lows:

– Higher risk of cavitation

– More seal wear

– Modified anti-wear properties

– Poorer filtration

– Reduced filter element service lives

– Modified friction characteristics

– Modified response to water

– More deposits due to additive reactions

– More system contamination due to dissolved deposits

– Modified water/air uptake and output properties

– Greater tendency to foam



5.4 Making the electrical connectionsDepending on the version, the filter unit has different drive mo-tors (different voltage / output / number of phases, etc.). Followthe instructions in the next section to electrically connect the fil-ter unit.

5.5 Electrically connecting the electric motorCheck the connection voltage as well as the frequency of theelectric motor and balance it with the available mains supply.You will find the electric data on the name plate of the electricmotor. Install a motor protection switch matched to the nominalcurrent of the electric motor.

DANGERDangerous electrical voltage warning

Danger of fatal injury

u All electrical jobs must be carried out by specialists withthe respective knowledge for the job.

u Pull the power plug and ensure the unit is deenergized.

Star connection

Delta connection

Check the direction of rotation on the electric motor in manualoperation. An arrow on the pump shows the correct direction ofrotation. If it is necessary to modify the direction of rotation,then exchange the two phases in the terminal box of the elec-tric motor.



5.6 Connecting the electric clogging indicator (optional)If the filter housing/filter unit has been fitted with an optionalelectric clogging indicator, connect it to your control center inaccordance with the switching logic.

2 Clogging indicators - technical data [} 67]

5.7 Connecting the suction/pressure portTake into account the pressure loss when connecting suction/pressure hoses. The suction / pressure hoses from the filterunit Accessories list are matched to the filter unit.

The pressure loss in a hydraulic line depends upon:

– Flow

– Kinematic viscosity

– Pipe dimensions

– Fluid density

The pressure loss can be estimated as follows for mineral oil-based hydraulic oils:

Fig. 15: Pressure loss formula

Δp Pressure differential [bar]L Line length [m]d Internal pipe diameter [mm]Q Flow [l/min]ν Kinematic viscosity [mm²/s]D Density [kg/dm³]

The mineral oil-based hydraulic oil has a density of ≈ 0.9 kg/dm³.



This formula applies to straight pipe runs. Particularly with re-gard to the suction side connection, note that additional con-nectors and pipe bends increase the pressure differential.

Observe the following points for hydraulic connection:

– Keep the height difference between the pump and the oillevel in the reservoir as small as possible.

– Use a suction hose that is suitable for a vacuum of ≥-0.5 bar.

– Avoid constrictions in the connected hoses. This reducesthe power and increases the risk of cavitation.

– Note that the nominal size of the connected hose/pipingmust correspond to the cross-section of the connectionthread.

– Make sure that the connection hoses/piping (suction side/pressure side) do not cause any tension or vibrations to becarried over to the filter unit. Use hoses or expansion jointsif necessary.



5.8 Inserting the filter elementThe filter unit has no filter element installed upon delivery fromthe factory. Before commissioning check whether a filter ele-ment is present in the filter housing.Install a filter element if it is not already installed. For details,see Changing the filter element [} 55].

5.9 CommissioningObserve and check the following points for commissioning:

ü Install the new filter element in the filter bowl. For de-tails, see Changing the filter element.

ü Check that the power supply cable is undamaged. Re-place damaged cables immediately.

ü Connect the filter unit with the power supply

ü Check that the suction and pressure hoses are undam-aged. Replace damaged hoses immediately.

ü Check the ambient and fluid temperature.

ü Prior to each use, match the oil type in the filter unit tothe oil type to be pumped. If you are not sure what sortof oil is in the filter unit, or if you would like to pump a dif-ferent type of oil than was most recently pumped, emptythe filter unit completely and replace the filter element.



1. Switch the filter unit on and monitor the suction perfor-mance.

ð If the filter unit is not pumping any fluid after a maxi-mum of 5 minutes of operation, then switch it off andfill the motor pump group with fluid through the suctionhose. Subsequently switch the filter unit on again.

O The filter unit is ready for operation.

HYDAC FILTER SYSTEMS GMBH Operation | 6


6 OperationDifferent operating modes are available depending on the ver-sion (see the model code) of the filter unit.

The filter unit is equipped with a clogging indicator (differentialpressure gauge or dynamic pressure indicator) in the filter bowlcover to monitor the service life of the filter element.

Visually check the optical clogging indicator daily. See chapter"Observing the optical clogging indicator (optional) [} 54]"

The optional visual/electrical clogging indicator signals the re-quired filter element change with an electrical switch which no-tifies the remote control room or another sensor.

When the contamination display has responded, exchange thefilter element. Refer to chapter "" for detailed information onchanging the filter element.
