1. Introduction and scope of application
Congratulations on purchasing your SEPAMAT E (Short name, SMT E).
The SMT E is designed as a separation unit, for use with small volume flows.
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 users. 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 user connection point can be a maximum of 10 m above the SMT E.

5.2 Components of diaphragm pump
5.2.1 Diaphragm pump
5.2.2 Fan
The fan cools the pump by a uniform air flow. If no continuous
operation is provided, the fan can be disconnected electronically.
This saves about 6W power. Nevertheless, if the pump is
operating continuously (without fan) with high back pressure and
the pump is getting too hot, the internal pump temperature sensor
will stop the pump. After cooling down the pump starts
automatically again.

1 2
6 cm
The floating valve keeps the water level
constant in the separation chamber. 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 6 cm.
Note: If an overflow occurs due to
continuous dripping from the valve, the
valve must be decalcified (see section 9).
The floating valve incorporates a
protective sieve.
5.4 Components of the pressure line set
The pressure line set contains an expansion tank, which is necessary to ensure the silent operation
of the system. A pre-pressure of 2.0 bar is preloaded at manufacture. The expansion tank ensures
that the vibration created by the operation of the pump is not transmitted through the piping system.
Procedure for pre-pressure inspection / preparation:
1.) Disconnect the mains power to the SMT E.
2.) Close the pressure shut-off valve.
3.) Open the vent cock to drain till the system pressure is 0 bar.

4.) Check the air pressure through the air valve with an air pump
and gauge (i.e. a bicycle or car tire pump).
If the pressure is too low, use the air pump to increase it
back to the necessary 2.0 bar.
5.) Reconnect the mains power to start the unit again and drain
the water, via the vent cock, until bubble free water gushes
out.
6.) Close the vent cock and open the pressure shut-off valve.
The system is now ready to use.
6. Installation instructions
The foam pieces between the chamber and pump are for
transport safety and must be removed before installation and
start up!

6.1 Wall mounting
The SMT E is mounted on the wall using the mounting material provided. The lid, bottom and
lateral distances indicated should be adhered to when mounting to provide clear maintenance
access.
275 mm
340 mm
>200 mm
>400 mm

>450 mm
The SMT E is fixed horizontally with of Ø8 mm raw plugs
and screws. An additional hole is also drilled 260 mm top
and right of the upper mounting holes for connection of the
expansion tank mounting bracket.
In order to avoid vibrations, the SMT E must be fixed with
all four screws.

SEPAMAT F_Manual_Vers.1.4f_en
12
6.2 Connection to the mains water line
The connection to the mains water line is done with the provided flexible hose with stopcock.
Note:
The flexible hose must not be mounted with tension, since the internal float valve is pressed against
the inner wall from here.
All provided flexible hoses have gland screws with flat seals. The rubber seals must be present.
Additional sealing material must not be used at gland nuts!
Screw the gland screw into the chamber connection and
carefully tighten with a 30 mm fixed wrench.
Screw the gland screw on the other end of the flexible
pipe into the stopcock mounted in the main water line.

SEPAMAT F_Manual_Vers.1.4f_en
13
6.3 Installation of the pressure line set
The pressure line set (see section 3) establishes the connection between the pump and pressure
line system.
The expansion tank is fixed to the wall with the pipe
clamps provided. The vent cock is equipped with a
gasket ring so that it can be screwed directly into the
T-piece without additional gaskets.
The pressure shut-off valve, incorporating the
pressure gauge, is then connected into the line by
screwing the flat sealing gland screw into the
expansion tank T-piece.
The flexible hose connects the pump pressure line to
the other side of the expansion tank T-piece. These
line connections are made with flat sealing gland
screws.
The expansion vessel pressure must be checked (see
section 5.4).

SEPAMAT F_Manual_Vers.1.4f_en

6.4 Connecting the emergency overflow
The SMT E has an emergency overflow line (DN 50) which must be connected to the waste
drainage system of the building. The drainage line must be of a size to accommodate a maximum
volume flow rate of 20 l/min.
The position of the backwater level must be taken into consideration while connecting to a drainage
system, in order to prevent backflow of drainage water from the open sewer line (design according
to the DIN EN 1717) entering the SMT E.
The position of the backwater level determines the type of line:
a) Backwater level above the emergency overflow
drainage height of the supplemental supply
container:
Connection of the emergency overflow must be
done by a lifting system.
b) Backwater level below the emergency overflow
drainage height of the supplemental supply
container:
Connection of the emergency overflow to a
ventilated channel line (DN 50) is done via a
siphon.

Mains water valve:
If the mains water valve continuously drips,
then this must be decalcified. Therefore,
remove the entire valve from the tank and
place it in a decalcifying solution (citric acid) so
that the inlet and outlet are fully submerged.
Move the floating arm several times so that the
decalcifying solution penetrates the valve
diaphragm chamber as well (24 hours
exposure time). If the dripping continues after
maintenance, then the valve must be replaced.
