Scope Of Supply; Installation Procedure - Kessel Pumpfix F Comfort Anleitung Für Einbau, Bedienung Und Wartung

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 connec-
ted to them. This guarantees the safe drai-
ning of draining spots below the backwater
level even during backwater. The pump only
works during backwater and pumps the soi-
led water into the sewage channel against
the backwater. During backwater-free ope-
ration, 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 on-site.
Important:
Pre-condition for trouble-free operation is
• Sufficient gradient in the draining pipes
(note: there is a drop of 9 mm between
inlet and outlet of the Pumpfix F)
• A sufficient amount of 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 pos-
sible with increased maintenance and
cleaning efforts
• Rain surfaces up to max. 20 m

2.2 Scope of supply

The scope of supply of the KESSEL back-
water pumping station Pumpfix F is made
up of the drain body with pump and back-
water valve and the electric packages.
The electric packages are made up of:
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 accor-
dance with chapter 3. Usually, the power
connection (chapter 4) and subsequent in-
itial operation (chapter 5) cannot be carried
out directly. Please connect the electric sy-
stem components (pump, probes, motor
and control unit) when you put the KESSEL
backwater pumping station Pumpfix F into
operation. Until this point, the enclosed el-
ectric package and the control unit must be
kept stored in a clean and dry place.
Care must be taken that the system is al-
ways sealed with an upper cover section
and cover or protective hood when set up
2 as a free-standing device in order to prevent
soiling of the system.
Caution: The pump is secured by a trans-
portation safety tape that has to be removed
before initial operation.

2.4 General instructions about the instal-
lation of backwater valves
According to DIN EN 12056 backwater val-
ves may not be used to protect all the drai-
ning 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 fur-
thest below the backwater level first (usually
basement rooms) and thus flood the base-
ment.
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.
