General - Kessel Staufix FKA Standard Installation And Operating Manual

2.1 Application
The KESSEL Staufix® SWA backwater
valve, designated as a DIN EN 13564
Type 3 backwater valve, is designed to be
installed in wastewater drainage pipes
with or without raw sewage (WC connec-
tion). The backwater valve prevents wa-
stewater from backing up the drainage
pipe during backwater / flooding. The FKA
should be kept in good operating conditi-
on and should be accessible at all times.
During normal operating conditions, the
motorized backwater flap as all as the ma-
nually lockable backwater flap are in the
open position. The system is equipped
with an optical probe that is automatically
closed when backwater is detected. When
the backwater occurrence is over, the mo-
torized flap opens itself automatically. The
system is also equipped with a second
backwater flap that can be manually clo-
sed and locked using the manual closure
and locking lever.
In addition, the manually operated back-
water flap offers a 'neutral' position (the
unit is shipped with the flap in the 'neutral'
position). During the construction phase,
the installed Staufix® FKA offers backwa-
ter protection with the manually operated
flap which is in the free hanging position –
this protection is offered even before the
system is connected to electrical power.
DIN EN 12056 and DIN EN 13564 should
be followed which regulated the drainage
of building and use of backwater valves..
2.2 Contents of Delivery
The Staufix® FKA delivery consists of a
body / housing with cover including the
emergency closure lever (closure lever
not included with a Controlfix®), and in-
stallation and operating manual (Article
Number 010-842), a see-thru test funnel
as well as an Electrical package (separa-
te box containing the electrical parts of the
system). Please carefully store this addi-
tional accessories before they are instal-
led to the system.
The electrical package consists of:
1.The optical probe as well as the motor
which operates the motorized backwa-
ter flap.
2.A control unit (230 V, 50 Hz, Protection
Class IP 54) with back up battery feature
(twin 9-volt batteries) – this offers an ad-
ditional 2 hours of operation in the case
of a power outage. Also included is the
installation and operational manual for
the control unit (art.- nr.010-845).

2.3 Pre-installation tips
During the building's construction phase
only the body of the system will be instal-
led and connected to the building's drai-
nage pipe (as discussed in Section 3).
Normally at this time power is not availa-
ble in the building meaning the Staufix®
FKA's motor is not in service (see chapter
4) and commissioning (see chapter 5)
cannot yet take place.
The electrical components of the system
(motor, optical probe and control unit)
should not be connected until the system
is commissioned (after the major con-
struction phase of the building is comple-
te). It is important that the electrical com-
ponents of the Staufix® FKA (contained in
the electrical package) be properly stored
(safe and dry) until they are ready for in-
stallation.
During the time period after the instal-
lation of the Staufix® FKA body and
before the Staufix® FKA is connected
to the building's power source, the fol-
lowing Staufix® FKA settings or positi-
ons are possible:
A)Locked position (Illustr. 1 – manually ope-
rated backwater flap is in the closed and
locked position). The red closure lever
should be pushed down into the locked po-
sition. This provided a full lockage or closu-
re of the building's wastewater pipe. In this
position no drainage fixtures connected to
the Staufix® FKA can be drainage as the
backwater flap is in the closed (locked) po-
sition. With the position the building is fully
protected against backwater flooding.
B)Fully open position (Illustration 2 – back-
water flap is in the fully open position). The
red closure lever should be in the open po-
sition. The backwater valve currently proved
no backwater protection to the building and
any wastewater from the building can free-
ly flow through the backwater valve. In this
position none of the fixtures connected to the
Staufix® FKA are protected from backwater!
C)Construction phase position (Illustr. 3 –
backwater flap is in the vertical free han-
ding position). The red manual closure
lever is in the 'open' position and the emer-
gency closure device should be in the 'neu-
tral' position. In this 'neutral' setting the ma-
nually operated backwater flap is in the
vertical (free hanging) position and acts as
a single flap backwater protection valve for
the building. The motorized backwater flap
is not in service and provides no protection.
In this position, drainage fixtures connec-
ted to the Staufix® FKA can be drained
19
and at the same time are protected against
backwater.
Before the Staufix® FKA is fully opera-
ble, we recommend the following set-
tings:
- If it is certain that no drainage fixtures
connected to the Staufix® FKA will be
used during the building phase, both the
operational and the emergency backwa-
ter flaps should be in the closed position
(see paragraph A above). If the drainage
fixtures connected to the Staufix® FKA
need to be in service during the building
phase, both the operational and the
emergency backwater flaps should be in
the temporary open (see paragraph C
above).
- It should be noted that the backwater
flap will be prevent backwater (be water-
tight) only if the wastewater contains no
debris or raw sewage.
