General Instructions About The Installation Of Backwater Valves - Kessel Pumpfix F Comfort Nstructions For Assembly, Operation And Maintenance

The KESSEL backwater pumping station
2.1 Use
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 sy-
stem must be protected from damage on-
site.
A rat protection flap is available as an opti-
on and prevents damage caused by gna-
wing to a large extent (Standard only).
Pre-condition for trouble-free operation is
Important:
• Sufficient gradient in the draining pipes
(note: there is a gradient of 9 mm bet-
ween 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 wastewa-
ter 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

connection (chapter 4) and subsequent in-

out directly. Please connect the electric sy-
stem components (pump, probes, motor
and control unit, depending on the variant)
when you put the KESSEL backwater pum-
ping 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 ope-
ration.

2.4 General instructions about the in-
stallation 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) - be-
cause if the backwater valve is closed, the
wastewater from above can no longer be
drained into the sewage pipe but will - ac-
cording to the principle of communicating
pipes - escape from the drainage points fur-
thest below the backwater level first (usual-
ly basement rooms) and thus flood the ba-
sement.
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 stre-
et level inside the downpipe without flooding
the basement.
Rainwater must never be discharged via
backwater valves.
