1. Introduction and scope of application
Congratulations on purchasing your SEPAMAT F-SC (SMT-F-SC).
The SMT-F-SC is designed as a separation unit, for use in single-family homes, apartment
buildings, offices and industry.
The DVGW certified, fully automatic and ready-to-connect separation unit fulfills the separation of
drinking water from category 5 liquids according to DIN EN 1717.
The integrated pump supplies water on-demand from the separation chamber to the consumers.
The water level in the separation chamber is controlled by a floating valve. The drinking water
supply and emergency overflow are connected to the separation chamber.
The highest consumer connection point above the SMT F-SC20 can be a maximum of 20 m and
with SMT F-SC 40 a maximum of 30 m.
The application range can be enlarged and the units connected in parallel series with up to three
SEPAMAT F-SC. The installation control system is communicated through wireless Bluetooth.

Speed control
In both modes (automatic/maintenance), the speed of the centrifugal pump is controlled by a
frequency converter corresponding to a set pressure level. The pressure is monitored via a built-in
analog pressure sensor. The current is monitored with the basic controller. This ensures 100% that
the pump never dry runs. All operating parameters such as time-delay, idle and load power
consumption and response time for the dry-running are specified by the controller.
Bluetooth connection
Two or three units of SEPAMAT F-SC can communicate with each other wireless via the integrated
Bluetooth and can be conveniently combined into a fully redundant, multiple pumping system. The
consecutive combination, cyclic switching of the pumps, connection with peak load and the
Master/Slave exchange is done automatically in case of the failure of device.

2. Safety instructions
The live components have to be installed only by a qualified electrician. In
case of failure of the electronic device, the product has to be repaired by a
qualified electrician before being operated again. There is a risk of electric
shock!
The outlet circuit used for the device has to be secured through a protected
circuit breaker (16 A in most countries). If unavailable, an FI switch with
maximum operating current of 30 mA has to be connected.
These installation and operating guidelines have to be read carefully before
installing the product. The instructions mentioned have to be strictly followed.
Modifications to the product are not permitted, otherwise the warranty
becomes void.
The following points have to be strictly observed during installation and operation:
•Check the product before installation for any visible defects. If defects are present, then the
product must not be installed. Damaged products can be dangerous.
•Installations at the mains water pipeline system can only be performed by a qualified
installation company.
•A floor drain has to be provided near the installation site, which can collect inadvertent water
discharges (i.e. pump defects, pipe breakages, etc.) and prevent water damage inside the
building.
•The mason work behind the water-handling unit must be protected from water damage (i.e.
with water-resistant coating).
•Make sure that the existing emergency overflows are connected and adequately sized.
•Remove the mains electrical plug if you will be away for more than 24 hours.
•Close the mains water line at the inlet of the device if you will be away for more than 24
hours.
•All products must be regularly inspected to maintain proper condition. The minimum
inspection interval is mentioned in the maintenance section.
•Electrical devices may be hazardous for children. Therefore children always have to be kept
away from the product. Do not let children play with the product.
•Do not install the water-handling units in locations where the temperature may drop below
0°C.
•Do not install any electrical products in flood-prone areas.
•The operator is responsible for adherence to the safety and installation guidelines.

5. Overview of components
The SMT-F-SC has a modular design. Each component can be separately exchanged.
5.1 Components of the pump controller
The pump controller (see section 4.1) monitors
the pressure in pressure line system and
maintains it at a constant level by speed
controller. The controller reduces power
consumption especially with small flow rates and
increases the service life of the pump.

5.1.2 Cable connection plan
In the event of a damaged cable or faulty pressure sensor, it is necessary to open the housing of
the pump control. To do this, the mains plug must be disconnected and you have to wait for at least
2 minutes until all LEDs turn off (internal capacitors are discharged). You may open the case only
after this. To do this, you have to demount the complete pump control from the angle holders. Then
the rear screws of the heatsink can be opened.

5.1.3 Self-initialization
Each SMT-F-SC pump is factory set for the initial pump control!
The below described self-initialization must be performed only when a program RESET was
conducted or if a new pump or a new pump control was installed.
In this automatic initialization, the characteristic current values are analysed at different operating
parameters, which form the basis of the speed controller.
1.)Make sure the pump is automatically primed with water (see section 7.1) when it first begins
operation.
2.)Open the air vent and let water flow out until there is no more air in the system. Then close the
pressure shutoff valve (pressure increases).
3.) In case the pressure of the system is > 3 bar, the stopcock must be opened again to reduce the
pressure to < 3 bar.
4.)Press
START
to start the self-initialization. After about two minutes (total pressure range of the
pump is analysed) the initialization is finished. The segmented LED indicator lights up one time,
from 0 all the way to 10 bar and the pump stops (LED Minimum Flow lights up).
5.)The self-initialization is now finished and the start-up procedure can follow (see section 7.2).
Changing the predefined discharge pressure of 3 bar is possible, if necessary, in 0.5 bar steps
by pressing the
+
or button (the pressure setting has been saved once the
segmented LED no longer blinks).
Command Button combination
RESET
(to restore factory
settings)
&
STOP
press simultaneously for 5 seconds (total
segmented LED indicator blinks once).
Pull the mains plug and wait until all the LEDs are off.
SELF-INITIALIZATION
Plugin the mains plug.
Press
START
to start the self-initialization.
Checking the pump start and stop
At the end of the self-initialization, test the start and stop of the pump system by turning on one or
more fixtures. When the pump stops, the yellow LED Minimum Flow will flash. When the fixtures
are opened, the pump must independently start again.
Checking the dry-running protection
In cases of water shortage, the pump must stop after 40 secs and the red LED Dry Working turn
on. This check is best performed by shutting the mains water supply valve and opening a fixture.

5.4 Components of separation chamber
The floating valve keeps the water level
constant in the separation tank. The
maximum water level should be approx. 2-
3 cm below the overflow rim when the
floating valves closed (backside of the
container).
The correct distance of the float (5) to the
horizontal lever is factory set at 8.5 cm.
Note: If an overflow occurs due to continuous
dripping from the valve, the valve must be
decalcified (see Maintenance).
The floating valve incorporates a protective
sieve.
