2. General


2.1 Areas of applicationThe Staufix® FKA is designed to be installedin a downward sloped, continous rundrainage pipe. In this application the Staufix®

FKA will provide through drainage duringnormal conditions and protection againstbackwater during times of backwater.

2.2 Staufix® FKA descriptionThe Staufix® FKAelectronic backwater valveconsists of:

© a body with motorized and manuallyoperated backwater flaps

© a motor (IP68, limited submersibility) tooperate the motorized flap

© an optical probe (IP 68, limitedsubmersibility)

© a splash proof control unit (120V - 60Hzor 230V - 50 Hz) with back up batteries(two 9 volts) for operation of the Staufix®

FKA for up to 10 hours after powerfailures

© Installation and User’s Manual© Funnel for watertight test

2.3 When to install the Staufix® FKAIf the Staufix® FKA is being installed duringthe construction phase only the body of thevalve and cover should be installed (themotor, optical probe and control unit shouldnot be installed or connnected) (Chapter 3).During this time make sure to store theelectrical components in a clean and dryplace. When the construction phase is overthe motor and optical probe should be

installed in the cover of the valve, the controlunit mounted on a nearby wall and allnecessary electrical connections made. Thiswill help prevent damage to the mechanicaland electrical equipment of the Staufix® FKAduring the construction phase.

During the construction phase the twoclosure levers of the Staufix® FKA can bemanually set in three different positions toprovide different protection options before allthe electrical connections to the Staufix®

FKA are made. The red manual closurelever and the motorized backwater flap levercan be both set in the ‘FLAP LOCKED CLO-SED’ position which will completely shutboth backwater flaps and not allow flow ineither direction. The red manual closure

2. General

lever can also be set in the ‘FLAP OPEN( F R E EHANGING)’ position (lever is vertical) andthe motorized backwater lever in the ‘FLAPOPEN (OUT OF FLOW)’ position whichallows plumbing fixtures to be drainedthrough the valve and also providesprotection against backwater because themanual backwater flap is in a closed but freehanging position. The red manual closurelever and the motorized backwater flap levercan also both be set in the ‘FLAP OPEN(OUT OF FLOW)’ position by releasing theflexible tab in the middle of the red manualclosure lever from the tab stop and pullingthe lever all the way back until it goes nofurther (beyond vertical). At this setting themanual backwater flap is completely openand will allow plumbing fixtures to be drained

through the valve.2.4 UpgradabilityThe KESSEL Staufix® FKA can be easily up-graded to the KESSEL Pumpfix® Felectronic backwater valve with opticalprobe, intregrated sewage pump and controlunit (North American Option -8, pleasespecify pipe size / European Order Number28079 for 3 inch pipe, Order Number 28080for 4 inch pipe or Order Number 28081 for 6inch pipe).


3. Installation

Please note:The drainage pipe to which the Staufix® FKAis connected is installed at the slope requi-red by the local governing code. It is recom-mended that all plumbing fixtures above thebackwater level be connected downstreamof the Staufix® FKA since these fixtures donot need to be protected against backwater.Only fixtures below the backwater levelshould be plumbed through the Staufix®

FKA.

8. Additional Functions

8.1 Self Diagnosis System (SDS)The Staufix® FKA control unit is equippedwith SDS. This system automatically teststhe motor and the motorized flap once everyweek. During this test the motorized flap willclose once, check to see that it can make acomplete water tight seal and then re-open.If faults or an obstruction in the valve isdetected during this test, the problems willbe indicated on the control unit and can becorrected by following the instructions inChapter 7.

8.2 Sleep modeThe Staufix® FKA can operate on batterybackup power for approximately 10 hoursafter which it will automatically go into sleepmode. This is a backwater protectionprecaution when outlet power is no longeravailable and battery power is low. When theStaufix® FKA goes into sleep mode it willshut the motorized flap until power is restoredto the unit. During this time there will be noaudible or visual warnings unless thesystem is equipped with the signalling devicewith auxiliary connection in which case thissystem will still receive a signal. Whenpower is returned to the Staufix® FKA it willreturn to normal operation.

8.3 Battery life and replacementWhile the Staufix® FKA is connected to asuitable power supply, the unit continuouslychecks the condition of the two batteries. Ifat time of initialization the batteries holdunder 12.5 Volts total power, the Staufix®

FKA will not initialize itself. In this case,unplug the Staufix® FKA control unit from itspower source, check and replace thebatteries if necessary and then reconnectthe control unit to its power source. Theestimated life of new batteries is four years.Batteries certified for use with the KESSELStaufix® FKA are Duracell 9 Volt Type MN1604/6LR61 (Requirement - 2).

10.3 Operational Check(According to DIN 19578)(Please see Illustration 18)

Close the motorized flap (#7) using the‘CLOSED / TEST FLAP’ button and alsoclose the manual flap by hand using themanual flap closure lever (#6). Remove the1/2 inch plug (#1) from the cover of theStaufix® FKAwith a large screwdriver and byhand screw on the funnel (#2) with itsextension if available (#3, not included).Now pour water into the funnel until a levelof 100 cm (1 meter) is reached. Over thenext ten minutes observe the water level inthe funnel and refill if necessary keepingtrack of how much water is needed to keepthe water level constant. If after ten minutesthe amount of water needed to keep thewater level constant at 100 cm is less than500 cubic centimeters (1/2 liter, approx 1/2quart), the backwater valve is considered tobe water tight. This is a performance test

used by the German Industry Norm. Afterthe test, remove the calibration funnel andextension tube by hand and with a largescrewdriver firmly replace the plastic plug.Re-open the manual closure lever by handto the ‘open’ (vertical) position and re-openthe motorized flap by pressing the ‘CLOSED/ TEST FLAP’ button on the control unit.

10.4 Testing the optical probe(Please see Illustration 19)Unscrew the two screws on the optical probe andremove the optical probe. Immerse the lens of theoptical probe in a glass of water. The motorized flapshould begin to close as well as the visual andaudible alarms sounding once the motorized flap isfully closed. As soon as the optical probe is removedfrom the water, the motorized flap should re-openand the visual and audible alarms should stop. If theoptical lens is dirty it should be cleaned with a cleansoft cloth or tissue. When finished, re-insert theoptical probe and tighten the two screws.
