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.
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 circuit
breaker protected (16 A in several 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 followed strictly.
Modifications to the product are not permitted, otherwise the warranty
becomes void.
The following points have to be strictly observed during the 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 fresh water pipeline system have to be only performed by a qualified
installation firm.
•A floor drain has to be provided near the installation site, which can collect inadvertent water
discharge (such as with pump defect, pipe breakage etc.) and prevent water damage inside
the building. The brickwork behind the water-carrying system must be protected from water
(such as with water-resistant paint).
•The wall material behind the water-handling system should be protected against water
damage (ie. water-tight coating).
•Make sure that the existing emergency overflows are connected and adequately sized.
•Remove the mains plug if you will be away for more than 24 hours.
•Lock the fresh 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 manual.
•Electric 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-carrying products in locations where the temperature may drop
below 0 °C.
•Do not install any electric products in flood-prone areas.
•The operator is responsible for adherence of the safety and installation guidelines.

4.2 Standards, directives, tests
The SMT E meets the DIN 1989-4 “Components for Control and Supplemental Supply“ standard for
rainwater harvesting systems. The DVGW mark of approval confirms the presence of the
mandatory “air gap“ (as per DIN EN1717) for secure separation of processed water from the mains
water line, which is integrated into the SMT E.

Mains water supplemental supply device, Type AB as per DIN EN 1717
The power is supplied via a TÜV GS-certified switching power supply. All components of the SMT E
are run on 24 V DC low voltage technology.
The above mentioned device corresponds with the basic safety and health requirements of the EC
directives for machines. Any modification of the device not coordinated by INTEWA will void the
warranty.
This equipment specifically fulfills the requirements of the following EU directives:
EC directives for machines (89/392/EWG) in accordance with 91/368/EWG
EC Low voltage directives (73/23/EWG)
EG Directives for electromagnetic compatibility (89/336/EWG) in accordance
with 93/31/EWG
The conformity of the equipment with the above mentioned directives is confirmed by the CE
symbol.
Applied harmonized EU standards:
EN 60335-1: 1194/A1/A11/A12/A13/A14, EN 60335-2-41: 1996

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.

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.
