If installing an extensionsection make sure to grease its rubbergasket. If more than one extension sectionis needed, be sure that the valve is notinstalled so deep that access to the valve forinspection, maintenance or use is hindered.Illus. 3Illus. 4Illus. 5Illus. 2Everything for drainage 4

2. Installation2.3 Installations subject to groundwaterThere are certain circumstances where theupward force of groundwater can penetratethrough slab installed fixtures and causemoisture problems. The KESSEL Staufix ®SWA provides protection against the upwardforce of groundwater by including thewater barrier (North American Option -5 /European Product Number 83019 (rubberbarrier) and Product Number 83018(flange)) during installation. This barrier issimply placed between the body of theStaufix ® SWA and the flange which is thenbolted tight by the included bolts as shownin Illus. 6.2.4 Installation in an exposed /suspended pipeNorth American Product Numbers 65053,65054 and 65056 / European ProductNumbers 73100.10, 73125.10 and73150.10.The Staufix ® SWA valve designed to beinstalled in an exposed / suspended pipecomes ready to be installed in a properlysloped drainage pipe. This valve is equippedwith a see-thru, easily removable protectivecover.2.5 UpgradabilityAll of the KESSEL Staufix ® SWAs areupgradable to either the KESSEL Staufix ®FKA electronic backwater valve with opticalprobe, motorized flap and control unit or thePumpfix ® F electronic backwater valve withoptical probe, intregrated sewage pump andcontrol unit. In preparation for a futureupgrading, when installing a Staufix ® SWA aDN 50 or 1.5 inch DWV Sched 40 PVC pipeshould be run under the floor from the backwatervalve to a nearby power source so thatfuture electrical connections can easily bemade. An example of this preparation can beseen in Illus. 1 and Illus. 5.ATTENTION:Make sure that no cables or otherobjects impair the movement of the manualclosure lever or interfere with the operation,inspection or maintenance of the valve.Illus. 6Illus. 7FlangeFlangeRubber barrierRubber barrier5Everything for drainage

3. Inspection / 4. Maintenance3. InspectionThe Staufix ® SWA should be inspectedmonthly by the owner or a professional toinsure that it is in proper operationalcondition. The manual closure lever shouldbe closed and opened several times toinsure that it functions properly. Pleasemake sure that upon completion of themonthly inspection that the manual closurelever is in the ‘FLAP OPEN (FREEHANGING)’ (vertical) position.4. MaintenanceThe Staufix ® SWA should be maintainedevery six months by a professional. Pleasemake sure that no fixtures are drainedthrough the Staufix ® SWA during thisinspection. The procedure for maintainingthe valve is in Sections 4.1 and 4.2 of thisInstallation and User’s manual (As seen inIllustrations 11 thru 14).4.1 Dissassembly, Cleaning and Reassembly.Illustration 11a) Close the manual closure lever.b) Loosen and remove the six bolts.c) Remove the cover.Illustration 12a) Remove both free hanging flaps alongwith their housings.b) Clean all parts (try not to remove any ofthe gasket and seal grease).c) Check all seals and sealing areas andreplace with KESSEL replacement partsif necessary.d) Check the complete Staufix ® SWA inaccordance with this manual.7Everything for drainage

4. MaintenanceIllustration 13a) Grease rubber gaskets and sealing areasif necessary.b) Replace flaps and housings in theirappropriate slots.c) Replace the cover. Retighten the six boltsin a crosswise pattern to a torque of 6 lbfft(8Nm).d) Return the manual closure lever to the‘FLAP OPEN (FREE HANGING)’(vertical) position4.2 Staufix ® SWA water tightness testfor double flap backwater valvesClose the flap by placing the manualclosure lever in the ’FLAP LOCKEDCLOSED’ position. Remove the red plasticcap (#1 in Illustration 14) with a largescrewdriver and screw in the suppliedsee-thru test funnel by hand. Pour waterinto the funnel until the water has reachedthe 100 mm mark on the funnel. Over thenext 10 minutes keep an eye on the waterlevel and refill to the 100 mm mark when necessarywhile keeping track of how much additionalwater has been added. If after the 10minutes less than 500 cubic centimeters (0.5liters, approx 0.5 quarts) of water wasneeded to keep the level at the 100 mmmark, the Staufix ® SWA has passed the watertightness test. This is a performance teststandard used by the German Industry Norm.After the test, remove the calibration funnelby hand and replace and tighten the redplastic cap with a large screwdriver. Returnthe manual closure lever to the ‘FLAPOPEN (FREE HANGING)’ (vertical)position.Illustration 14Red capFunnelEverything for drainage 8

5. UpgradingThe KESSEL Staufix ® SWA can be easilyupgraded to the Staufix ® FKA electronicbackwater valve with optical probe, motorizedflap closure and control unit (EuropeanOrder #80081 for 3 inch pipe or Order#80080 for 4 and 6 inch pipe) ( NorthAmerican Option -9, please specify pipesize) or to the Pumpfix ® F electronicbackwater valve with optical probe,integrated sewage pump and control unit(European Order #28079 for 3 inch pipe,Order #28080 for 4 inch pipe or Order#28081 for 6 inch pipe) (North AmericanOption -8, please specify pipe size). It isimportant that when installing the Staufix ®SWA that a 1.5 inch Schedule 40 DWV (DN50) pipe is connected from the Staufix ®SWA to a location where a control unit couldbe located so that the electrical cables of anew electronic valve can be easily connected(as seen in Illustration 1 on page 3).Upgrading the Staufix ® SWA is done bysimply removing the cover and backwaterflaps of the Staufix ® SWA and replacing itwith either a Staufix ® FKA or Pumpfix ® Fupgrade cover. Cables for the optical probeand motor or pump are then run through thepre-installed 1.5 inch Sched 40 DWV PVC(DN 50) pipe or directly to the control unitwhich is to be mounted on a nearby wallwith the included mounting hardware.9Everything for drainage
