Installation4.Installation4.1.2 Requirements for the place ofinstallation4.1GeneralThe room where the unit is installed mustbe dry and frost free!ATTENTIONUnauthorised persons must not have access to the filter!(see chapter “Safety informationdangers due to non-compliance”)andATTENTIONThe unit may only be installed by skilled personnel.(see chapter “Safety informationdangers due to non-compliance”)The chapter on “Intended use” must alwaysbe observed!–The ambient temperature must notexceed 30 C (86 F)! At highertemperatures or direct sun radiation thematerial can be damaged and the filterhood can even break.–In order to be able to safely dischargethe wastewater in operation and in caseof any defects that occur in the system,precise compliance with the details given in the “Installation” chapter is necessary! If the wastewater (backwashing)cannot be safely and completely discharged, the house and installations canbe damaged by water.–A shut-off valve must be installed upstream of the filter! This enables the water supply to the filter to be interruptedduring installation, servicing/maintenance, repairs and in case of malfunctions. Floods and serious water damageto house installations can therefore beavoided.4.1.1 Transport / storage–The automatic backwash protective filtershall be protected towards heavy impacts.The unit can be installed in all standarddrinking water pipes.–It is not permitted to install the automaticbackwash protective filter upstream ofthe water meter!–A power outlet above the filter with constant electricity supply within a distanceof max. 1.5 m (60 inch) is required for themains adapter of the automatic filter.The pipes must be able to safely support thefilter.Otherwise mechanical damage or fractures/bursts can occur in the pipes. This can resultin major water damage. People close to thefilter are exposed to a health risk due to thelarge quantities of water released. Therefore, if necessary, the pipes must be additionally fixed or supported.For convenient operation and maintenanceit is absolutely necessary to ensure the given spacings (see chapter “Dischargingbackwash water”).A space of at least 100 mm (4 inch) shouldbe maintained above and below the filter.These distances are necessary to be able toproperly carry out the backwashing (seechapter “Backwashing”).10JUDO PROFIMATand

Installation4.1.3 Installed positionIn this case, people close to the filter are exposed to a health risk due to the large quantities of water.ATTENTION(see chapter “Safety informationdangers due to non-compliance”)andAlways install the filter in a vertical position( 5 )!Failure to observe this can cause uncontrolled backwashing water to escape andcan result in water damage.Therefore, during installation, ensure that nolarge forces act on the pipe, built-in rotaryflange and filter.4.1.5 Installing the automaticbackwash protective filterJPF-A ¾" - 2"III4.1.4 Mounting the built-in rotaryflangesJPF-A ¾" - 2"Install using the supplied built-in rotaryflange. The built-in rotary flange is used as aconnecting element between the pipe andthe filter.It is suitable for both horizontal and verticalpipes.The built-in rotary flange must be installed in the direction of flow. This ismarked by a cast in arrow.(see fig. 5)Failure to comply with this means the filtercannot work.Fig. 4:The built-in rotary flange for the filter issupplied with bayonet drill holes. The necessary seals and screws for this filter havealready been mounted.Do not unscrew the screws!–Insert the four flange screws in thebayonet drill holes on the built-in rotaryflange (see fig. 4 I).–Turn the filter in a clockwise direction asfar as it will go (see fig. 4 II).–Tighten the four flange screws.ATTENTION(see chapter “Safety informationdangers due to non-compliance”)Built-in rotary flange with bayonet fixtureandThe flange surface of the built-in rotaryflange must be in a horizontal position! Thebuilt-in rotary flange must be fitted so thatmechanical stresses cannot occur! Otherwise mechanical damage can result in thebuilt-in rotary flange. Otherwise mechanicaldamage can result, the pipe may burst or thebuilt-in rotary flange can break. This can result in major water damage.Select the torque (approx. 4 Nm)so that the gasket closes and thefilter is not damaged or strained!ATTENTION(see chapter “Safety informationdangers due to non-compliance”)JUDO PROFIMATand11

InstallationThe section of the profiled flange gasketmust point towards the built-in rotary flange.Failure to observe this can lead to leaks andwater escaping. This can in turn cause waterdamage to the house and its installations(see fig. 5).4.2Discharging backwash waterATTENTION(see chapter “Safety informationdangers due to non-compliance”)andAn adequately dimensioned wastewaterconnection (e.g. floor drain) must beavailable for the backwashing water.The dimensioning depends on conditions onsite (e.g. wastewater pipe gradient, numberof pipe bends, length of the wastewaterpipe, etc.). The dimensioning must at leastallow all the wastewater to be discharged atthe same time.Profiled flange gasketFig. 5:Built-in rotary flangeEnsure that the wastewater connection functions before plugging the power supply unit intothe socket.JPF-A 2½" - 4"Installation of filters of the nominal size 2½"to 4" should be accomplished perpendicularly only if there is no possibility for horizontal installation. During operation in a perpendicular conduit, the coarse particles deposited in the sludge collector cannot be asoptimally flushed as while operating horizontally.The filters of nominal sizes 2½" to 4" have aflange connection according to DIN 2633.If it is not possible to provide a wastewaterconnection directly beneath the automaticbackwash protective filter, the flushing watercan be fed several metres to the next wastewater connection, either through a hose or apipe to be fitted to the flushing water valve.This pipe must have the same dimension asthe flushing water valve.In all options, a free discharge must be ensured.4.2.1 Instructions for safe useTo ensure a long life cycle of the filter andsieve insert it is necessary that the backwashing stream at pressures higher than30 psi (200 kPa) is throttled by means of aflush-cock. Thus the screen cloth is prevented from being damaged by too effectedcleaning-up streams. At the same time theflushing water consumption is reduced andpossible flow noises are avoided.12JUDO PROFIMAT

Operation5.3Differential pressure controlMode of operation:The impurities filtered off and caught on thefilter cloth cause an increased differentialpressure between the inlet and the outlet ofthe filter at an adequate flow rate. The differential pressure switch registers the differential pressure prevailing on the filter. If the differential pressure reaches the set value, thebackwashing procedure will be automatically initiated.Setting of differential pressure:The selector shaft of the differential pressure switch is set at the adjusting screw. Thevalue can be adjusted with a screwdriver between 0.9 psi (6.2 kPa) and 9 psi (62 kPa),see scale.If the value is set too high, dirt may accumulate with low flow rate. During times of higherwater removal the differential pressure willincrease to an extent that damages at thescreen may occur.The differential pressure switch is directlyflanged to the filter via intermediate flange.Caution!Scale unit in bar (1 bar 14.5 psi / 100 kPa)cable for electric circuitadjusting screw for differentialpressure adjustmentconnection inletpressureconnection outletpressureFig. 9:16Differential pressure switchJUDO PROFIMAT

Operation5.5Functional descriptionThe automatic backwash protective filter removes all coarse- and fine-grained impurities. These impurities may cause pitting corrosion as aeration elements in cold waterpipes and warm water supply systems, leading to malfunction of fittings, control unitsand sensitive devices.In the automatic backwash protective filter,the water flows outside-inside through acylindric screen insert. Impurities can beseen through the filter hood. If the filter iscontaminated, it will be cleaned without interruption of operation.18JUDO PROFIMAT

Operation5.6Backwashing5.6.1 Backwashing intervalThe filter must be backwashed ( cleaned)at the specified cycles in order to remove thefiltered dirt from the fine filter screen.All filter sizes are backwashed withtreated water. The treated watersupply within the domestic installation is maintained throughout thebackwashing performance. Duringthe backwashing any wastewatercan't get into the pure water side.Unauthorized persons must not operate thefilter! Persons who operate the filter mustobserve the operating instructions. Failureto observe these instructions can result indamage to property and personal injuries.ATTENTION(see chapter “Safety informationdangers due to non-compliance”)andThe cleaning-off is effected by means of thepoint-rotation method:The smaller the mesh size of the screen insert the more frequently backwashing has tobe effected!Spiralled rotation of suction trunks aroundthe sieve cloth of the fine filter. These progress upwards with each turn till the entiresieve cloth will have been sucked off once.Experience shows that increased dirt is deposited during the initial running period. Ifso, the unit has to be flushed more oftenthan usual.At the same time, the flushing valve at thebottom of the filter opens and the backwashwater can exit. During this time, pure waterstreams inside-outside passing through thesieve surface into the suction trunks, carrying away the adhering particles.Failure to flush in good time can cause damage to the screen. Larger quantities of filtered particles can deform the screen and asan extreme incident cause the tearing of thesieve. As a result a filter function is not anylonger ensured. In addition, larger quantitiesof dirt can cause mechanical impairmentconcerning the backwashing function.After reaching the upper limit-stop, the flushing valve is closed again and the sieve clothof the fine filter is sucked off a second timeby the suction trunks. Repeat this performance till reaching the lower limit-stop. During this step, the suction trunks do not onlyclean the sieve cloth of the fine filter but alsothe transparent filter hood by means of arubber lip on its exterior (see fig. 10).The degree of pollution as wellas the cleaning off operation canbe watched from outside.20JUDO PROFIMAT
