2. General
5
2.1 Areas of application
The Pumpfix
®
F is designed to be installed
in a downward sloped, vented, continous
run drainage pipe. In this application the
Pumpfix
®
F will provide through drainage
duringnormal conditions, protectionagainst
backwater during times of backwater and
thedrainage of connectedplumbingfixtures
even during times of backwater. When a
fixture plumbed into the
Pumpfix
®
F is
drained during times of backwater, the
Pumpfix
®
F will intake the wastewater,
macerate any solids with its cutting pump
and pump out the waste against the
pressure of the backwater.
Important:
A requirement for trouble free operation is
thatthe Pumpfix
®
F isinstalled in apipewith
proper slope and ventilation.
2.2 Contents of delivery
The Pumpfix
®
F package includes the valve
itself (with pump and backwater flap) and a
control unit. Included with the splash proof
control unit (230V - 50 Hz) is the optical
probe and Installation and Userʼs Manual.
2.3 When to install the Pumpfix®F
If the Pumpfix
®
F is being installed during
theconstruction phase ofabuildingonly the
body of the valve with cover and pump
should be installed (the optical probe and
control unit should not be connnected)
(Chapter 3). During this time make sure to
store the electrical components in a clean
anddry place. Whentheheavyconstruction
phase of the building is complete the optical
probe should be installed in the cover of the
valve, the control unit mounted on a nearby
wall and all necessary electrical
connections made. This will help prevent
damage to the mechanical and electrical
equipment of the Pumpfix
®
F during the
construction phase.
3. Installation
Please take caution that:
The drainage pipe to which the Pumpfix
®
F
is connected is laid at the slope required by
the local governing code and that the inlet
pipe to the
Pumpfix
®
F is properly vented. It
is recommended that all plumbing fixtures
above the backwater level be connected
downstream of the
Pumpfix
®
F since these
fixtures do not need to be protected against
backwater. Only fixturesbelowthe backwater
level should be plumbed through the
Pumpfix
®
F .

®
F body is completely adju-
stable. This access chamber can be raised
or lowered to meet floor heights, tilted late-
rally to meet grades in the floor and rotated
to match floor patterns.
3.2 Deep installation in a concrete
slab / floor
For deep installation depths use the
extensionsection (Product Number83070).
If installing an extension section make sure
to grease the rubber gasket. If more than
oneextension section isneeded,makesure
notto install the
Pumpfix
®
F sodeep that ac-
cess to the valve for inspection and mainte-
nance is hindered.
3.3 Installation subject to groundwater
There are certain circumstances where the
upward force of groundwater can penetrate
through slab installed fixtures and cause
moisture problems. The KESSEL
Pumpfix
®
F provides protection against the upward
force of groundwater by including the water
barrier ( Product Number 83019 (Rubber
barrier) and Number 83018 (Flange)).This
rubber barrier
is simply placed between the
bodyof the Pumpfix
®
F andthe flange which
is then bolted tight with the included bolts
as shown in Illustration 6.
3.4 Installation in an exposed /
suspended pipe
The Pumpfix
®
F backwater valve, designed
to be installed in an exposed / suspended
pipe, comes equipped with a see-thru,

6. Operation
6.1 Principle Functions
1. Normal operation 2. Backwater operation
3. Wastewater disposal during
backwater
As backwater occurs, the free hanging flap
is forced closed due to the pressure of the
backwater and provides a complete seal
against the back-up of wastewater into all of
the
Pumpfix
®
F protected areas.
During times of backwater the Pumpfix
®
F pro-
tects a building against the back-up of waste-
water while at the same time disposing of its
waste. This is possible because of an optical
sensor and integrated sewage pump located
withinthe
Pumpfix
®
F .Asa buildingʼsplumbing
fixtures are drained during times of backwater
the wastewater level rises inside the piping sy-
stemand the
Pumpfix
®
F .Thisis sensed by the
opticalprobe which activatesthecuttingpump.
The pump intakes the wastewater, macerates
the solids and pumps against the pressure of
thebackwater.Theintegratedfree hanging flap
preventsthe greywater orsewagefromflowing
back into the building.
During normal conditions the Pumpfix
®
F
functions as a standard backwater valve as
shown in the ʻNormal Operationʼ illustration
above. The force of the free flowing waste-
waterpushes the freehangingflapopen and
allows the waste water to pass unhindered
to a public sewer line or a private sewage
system.

6.2 Custom Pump Settings
The Pumpfix
®
F is delivered pre program-
med so that it can be installed and used
effectively without setting any of the custom
pump settings. The pre programmed setting
will handle all drainage and backwater
scenarios. However, customized pump
settings can be programmed if adjusting the
settings of the
Pumpfix
®
F can increase
performance and longevity.
Programming the Pumpfix®F
For programming the Pumpfix
®
F use the
LED numbers as identified below
LED 1 : ʻPOWERʼ LED
LED 2 : ʻALARMʼ LED
LED 3 : ʻPROBE SUBMERGEDʼ LED
LED 4 : ʻPUMPING / TEST PUMPʼLED
Setting the pumping times.
The Pumpfix
®
F can be programmed to
adjust how long the pump runs. This is done
by keeping both the ʻALARMʼ and ʻPUM-
PING / TEST PUMPʼ buttons pressed for a
few seconds until the continuous alarm tone
sounds. After releasing the ʻALARMʼ and
ʻPUMPING / TEST PUMPʼ buttons the
currentpump time settingcanbedetermined
by the blinking LEDs (please see table
below). The length of pumping time can now
be programmed. To change the pumping
times press the ʻALARMʼ button. Each time
the ʻALARMʼ button is pressed, 5 seconds
will be added to the pumping time. The
newly enterred times can be determined by
one or two blinking LEDs and checking with
the table below. When the desired pumping
time has been enterred press the ʻPUM-
PING / TESTPUMPʼ button to save the new
setting. The new pumping time changes will
be confirmed by a two toned audible signal.
If within 20 seconds the changes are not
saved by pressing the ʻPUMPING / TEST
PUMPʼbutton, the Pumpfix
®
F will automatically
save the previous pumping time (this will be
confirmed by a single tone audible signal).

6. Operation
Setting the ʻPump start delayʼ times.
The Pumpfix
®
F can be programmed to
delay starting the pump after the optical sen-
sor
has sensed wastewater. The advantage
of this is that the wastewater will have a
chance to build up in the pipe so that the
Pumpfix
®
F can pump out the entire volume
with one activation rather than turning on
and off several times. To change the ʻPump
start delayʼ times keep both the ʻALARMʼ
andʻPUMPING /TESTPUMPʼbuttonspres-
sed for a few seconds until the continuous
audiblealarm sounds. Release theʻALARM
and ʻPUMPING / TEST PUMPʼ buttons.
Now again press both the ʻALARMʼ and
ʻPUMPING / TEST PUMPʼ buttons for a few
seconds until the continous audible alarm
sounds again and the ʻPOWERʼand ʻALAR-
Mʼ LEDs light. After releasing the ʻALARMʼ
and ʻPUMPING / TEST PUMPʼ
buttons the current pump start delay time
setting can be determined by the blinking
LEDs (please see table below). To change
the pump start delay times press the ʻALAR-
Mʼ button. Each time the ʻALARMʼ
button is pressed, additional time will be
added to the pump start delay time. The
enterredtimes can bedeterminedbylooking
at the blinking LEDs and checking with the

delay time has been enterred press the
ʻPUMPING/TESTPUMPʼbutton to savethe
new setting. The new ʻPump start delayʼ
times will be confirmed by a two toned
audible signal. If within 20 seconds the
changes are not saved by pressing the
ʻPUMPING / TEST PUMPʼ button, the
Pumpfix
®
F will automatically save the
previous ʻPump start delayʼ (this will be
confirmed by a single tone audible signal).
The Pumpfix®F isdelivered pre-programmed
with a pump start delay time of 1 second.
Setting to either ʻFinish Controlledʼ or ʻStart
Controlledʼ modes.
The Pumpfix
®
F can be programmed to
operate in either ʻFinish Controlledʼ or ʻStart
Controlledʼ modes. In the Finish Controlled
pump setting mode, the optical probe
senses the build-up of wastewater in the
drainage pipe and activates the

8. Additional functions
8.1 Self Diagnosis System (SDS)
As part of the SDS Control unit, the
Pumpfix
®
F automatically tests its pumping
system once per month. As part of this self
test,the pump willrunfortwo seconds. Ifthe
Pumpfix
®
F detects any problems with its
operation during this monthly test, it will
display the problem on the control unit as
described in Chapter 7. This is an important
reason that the
Pumpfix
®
F always be
unplugged before maintaining or inspecting
the unit. With the Pumpfix
®
F unplugged
there is no risk of unintended activation of
the pump.
8.2 Battery life and replacement
While the Pumpfix
®
F is connected to a
suitable power supply, the unit continuous-
ly checks the condition of the two batteries.
If at time of initialization the batteries hold
under 12.5 Volts total power, the
Pumpfix
®
F will not initialize itself. In this case, unplug
the
Pumpfix
®
F control unit from its power
source, check and replace the batteries if
necessary and then reconnect the control
unit to its power source. The estimated life
of new batteries is four years. Batteries
certified for use with the KESSEL
Pumpfix
®
F are Duracell 9 Volt Type MN 1604/6LR61
(Requirement - 2). If discarding batteries,
please do so properly.
8.3 Battery function
The purpose of the batteries is to notify the
user of a power failure by LED and audible
alarm notification. Although during a power
failure the Pumpfix®F will continue to provi-
de
protection against backwater due to its
free hanging backwater flap, the pump of
the Pumpfix
®
F will not operate.
Please note: The auxiliary device is
certified for up to 42 Volts / 0.5 A.
