1. Safety instructions 

tentially explosive areas. 

The system contains electric charges and 

controls rotating mechanical system components. 

Non-compliance with the operating 

instructions may result in considerable 

damage to property, personal injuries 

or even fatal accidents. 

The system must be disconnected 

from the mains or made currentless 

before any work is carried 

out on it. 

It must be ensured that the electric cables 

as well as all other electrical system 

equipment are in a faultless condition. In 

case of damage, the system may on no 

account be put into operation or must be 

stopped immediately. 

The system must be inspected and serviced 

according to DIN 1986 to maintain its 

operational ability. 

We recommend that you conclude a servicing 

contract with your installation company. 

2 

No repairs or maintenance work may be 

carried out during a backwater situation or 

if a backwater situation is imminent. The 

backwater flaps and the locking lever always 

have to be able to be moved freely. 

Note: 

No system components may be installed 

in protection zone 0 or 1 in accordance 

with DIN VDE 0100 701. In the case of 

flush-to-floor showers, zone 1 is defined 

as with a radius of 1.20 m (projected area 

on the floor) around the water intake point. 

Deviating local regulations must be taken 

into account. 

The regulations set out by the directives 

VDE 0100, VDE 01107, IEC or by the local 

power supply industry must be heeded. 

The control unit must not be installed in 

rooms where there is an explosion hazard. 

For the operation of this system, 

these instructions and instructions no. 

010-846 must be used together!

2.1 Use 

The KESSEL backwater pumping station 

Pumpfix ® F has been designed for through 

wastewater pipes that have soiled water 

pipes as well as toilets and urinals connected 

to them. This guarantees the safe draining 

of draining spots below the backwater 

level even during backwater. The pump only 

works during backwater and pumps the soiled 

water into the sewage channel against 

the backwater. During backwater-free operation, 

the soiled water is discharged into 

the sewage channel through the natural 

gradient. 

Pumpfix ® does not provide protection 

against rats! If there is a rat hazard, the system 

must be protected from damage onsite. 

A rat protection flap is available as an option 

and prevents damage caused by gnawing 

to a large extent (Standard only). 

Important: 

Pre-condition for trouble-free operation is 

• Sufficient gradient in the draining pipes 

(note: there is a gradient of 9 mm between 

feed and drain with Pumpfix® F) 

• A high share oSufficient gradient in the 

draining pipes (note: there is a gradient 

of 9 mm between feed and drain with 

Pumpfix® F) 

• A high share of water in the wastewater 

to optimise the self-cleaning effect 

• Correct routing and ventilation of the 

feed pipe in accordance with DIN EN 

12056 / DIN 1986-100 

• Use with greasy wastewater only possible 

with increased maintenance and 

cleaning efforts 

• Rain surfaces up to max. 20 m 2

2. General 

2.2 Scope of supply 

The scope of supply of the KESSEL backwater 

pumping station Pumpfix ® F is 

made up of the drain body with pump and 

backwater valve and the electric packages. 

The electric packages are made up of: 

Standard 

1. The optical probe 

2. A control unit (mains connection 230 V, 

50 Hz, protective rating IP 54) with battery 

back-up (2 x 9V) for alarm message 

in the event of a power failure. 

3. An installation and operating manual 

Comfort 

1. Two optical probes and the drive motor 

2. One control unit with display (mains 

connection 230 V, 50 Hz, protective rating 

IP54) with battery back-up (2 x 9V) for 

alarm message in the event of a power 

supply. 

3. An installation and operating manual 

2.3 Installation procedure 

During the construction phase only the drain 

body is installed and connected in accordance 

with chapter 3. Usually, the power 

connection (chapter 4) and subsequent initial 

operation (chapter 5) cannot be carried 

out directly. Please connect the electric system 

components (pump, probes, motor 

and control unit, depending on the variant) 

when you put the KESSEL backwater pumping 

station Pumpfix® F into operation. Until 

this point, the enclosed electric package 

and the control unit must be kept stored in a 

clean and dry place. Only remove the plug 

end plates when the system is put into operation. 

Care must be taken that the system is always 

sealed with an upper cover section 

and cover or protective hood when set up as 

Right!

Caution: The pump is secured by a transportation 

safety tape that has to be removed 

before initial operation. 

2.4 General instructions about the installation 

of backwater valves 

According to DIN EN 12056 backwater valves 

may not be used to protect all the draining 

points of a building - including those 

above the backwater level (street level) - because 

if the backwater valve is closed, the 

wastewater from above can no longer be 

drained into the sewage pipe but will - according 

to the principle of communicating 

pipes - escape from the drainage points furthest 

below the backwater level first (usually 

basement rooms) and thus flood the basement. 

Only draining points below the backwater 

level may be protected against backwater. 

All draining points above the backwater 

level must be discharged into the sewage 

pipe with free gradient past the backwater 

valve. 

Consequence: separate pipe routing. 

Domestic wastewater above the backwater 

level can thus rise up to a maximum of street 

level inside the downpipe without flooding 

the basement. 

Rainwater must never be discharged via 

backwater valves. 

Installation of a backwater valve in the wrong place 

Wrong! 

Backwater 

level

Please note: 

DIN EN 12056 must always be heeded when 

routing the base pipes. Downpipes must always 

be introduced downstream from the 

Pumpfix® F (about 1m). In addition, a stilling 

section must be observed upstream and downstream 

of the FKA (at least 1 m). During installation 

of the backwater valve, care must be 

taken that there is a sufficient gap to the wall 

for maintenance work to be carried out. The 

KG pipe must not be connected directly to the 

drain body but only to the muff. 

Caution: During installation pay attention 

to the direction of flow arrows on the product. 

3.1 Kessel backwater pumping station 

Pumpfix ® F for installation in the 

ground plate 

DThe drain body of the KESSEL-Pumpfix® F 

must be aligned horizontally (see Fig. 1). 

For connection of the electric cables of probe 

and pump, a cable conduit (at least DN 50, 

Kessel recommends 2 x 45° bends) must be 

provided. A second probe cable and motor 

connection cable must be connected for the 

Komfort variant. For this, a cable conduit (at 

least DN 70, Kessel recommends 2 x 45° 

bends) must be planned. To do this, lay the 

cable conduit to at least finished flooring height 

(see Fig. 2) and insert in the cable duct in the 

adapter of the KESSEL Pumpfix® F (cable 

conduit should protrude about 2 cm into the interior 

- tightness (Fig. 5). Changes of direction 

must be laid with bends of max. 45°. To guarantee 

proper aerating and venting of the pump 

chamber, the cable conduit must not be sealed 

airtight. Insert the enclosed profile lip seal into 

the adapter groove and grease this. Then 

mount the upper cover section (see Fig. 3). 

Thanks to the telescopic design of the upper 

cover section, the KESSEL-Pumpfix® F can be 

adapted exactly to the prevailing installation 

depth. Ground slopes of up to 5° can be compensated. 

The upper cover section can also be 

turned to align the cover to the tile pattern, for 

example (see Fig. 4). The seal must be 

checked for a good fit after adjustment. 

CAUTION: 

The upper cover section must be shortened 

to the necessary size to achieve minimum 

installation depth. If necessary, 

recesses must be cut out of the upper 

cover section near the cable conduit and 

the ventilation pipe. Maximum groundwater 

resistance is 2 m. Following final 

alignment of the upper cover section, a 

recess may have to be introduced near 

the cable duct to enable the cable to be 

pulled out again during later inspections 

(see Fig. 5). 

The lip seal must be fitted in the cover plate. 

Care must be taken that the sealing lip and 

3. Installation 

centring lug are facing upwards during installation. 

The centring lug must be placed in the 

recess (see Fig. 6). 

During installation, make sure that the function 

of units in the chamber is not impaired by construction 

material. 

Installation of covers with a choice of finishes 

(tile height max. 15 mm). 

With the covers with a choice of finishes, tiles 

or natural stone can be inserted in the cover on 

site, so that they can be matched to the roomʼs 

flooring. Products e.g. from PCI, Schomburg, 

Deitermann are suitable for tile laying. To 

achieve straightforward processing and adhesion, 

we recommend the following procedure: 

Tile laying: 

a) aPrime the cover plate e.g. with PCI primer 

303. Following the respective flash-off time, 

lay the tiles with silicone. This type of laying 

is particularly suitable for thinner tiles since 

the base can be filled up to the required 

height. 

b) Laying the tiles e.g. using PCI Silcoferm S 

(self-adhesive silicone). This allows a thin 

adhesive bed to be used, particularly good 

for thicker tiles. 

Laying natural stone: 

(marble, granite, agglo-marble): 

a) Prime the cover plate e.g. with PCI primer 

303. Lay the natural stone panels using e.g. 

PCI-Carralit.. 

b) Laying the natural stone panels using e.g. 

PCI-Carraferm (special silicone for natural 

stone). Areas of application analogue to 

“Laying tiles”. 

3.2 Recessed installation in the ground 

plate 

(order no. 83071). Chapter 3.4 must be heeded 

for installation in water load. 

Depending on the installation depth, one or 

max. two extension pieces can be used between 

the upper cover section and the adapter. 

The respective seals must be greased accordingly. 

Please note that with recessed installation you 

still have to be able to reach down to the drain 

body for maintenance purposes. 

3.3. Ventilation connection 

Pumpfix® F is fitted as standard with a ventilation 

valve with activated carbon filter. Alternatively, 

ventilation according 

to standard 

can be connected. For 

this, the ventilation 

valve can be removed 

and connected directly 

to a ventilation pipe 

(to the roof).

3.4 Installation in an exposed wastewater 

pipe 

The version for free-standing set-up is delivered 

with a protective hood to prevent damage to 

the components following commissioning. Fig. 

7 shows the cable ducts – 1 or 2 (depending on 

the variant). 

3.5 Installation in water load 

(Seal set art. no. 83023 

Fig. 7 

If the valve is to be installed in water load, 

the flange serves as the necessary sealing 

level for a white or black tub (see Figure). 

For this purpose, seal sheeting is clamped 

between the plastic counterflange and the 

compression seal flange integrated on the 

drain body, and screwed together using the 

enclosed screws. 

The sheeting used on site can be used as 

seal sheeting. For installation in a waterproof 

white tub, KESSEL also has matching 

seal sheeting available made of natural rubber 

NK/SBR, where the bore holes for the 

screws have already been cut out (see Fig. 

8). 

If it is necessary to perforate the waterproof 

concrete tub to connect feed pipes, cable 

conduits etc., these holes must also be set 

up waterproof. Maximum groundwater resistance 

is 2 m.
