Page 4: Modes Of Operation
1.1 Modes of operation Automatic mode In Automatic mode, the diaphragm pump carries rainwater from the tank into the home and onto respective applications (e.g. toilets etc.). If the tank is empty, this is then detected by the float switch in the tank which instructs the electronic 3/2‐way motorised ball valve to change to the mains water mode. The suction line is then blocked and the required mains water is taken from the built‐in supplemental supply ... -

Page 16: Components Of The Supplemental Supply Container
5.3 Components of the supplemental supply container The floating valve keeps the water level constant in the supplemental supply container. The maximum water level should be approx. 2 cm below the overflow rim when the floating valve is closed (backside of the container). The water level can be adjusted by twisting the black lifting body. 1. Lid The floating valve incorporates a protective sieve. ... -
Page 17: Components Of The Pressure Line Set
5.5 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 primary 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 pressure control / maintenance of the primary pressure: 1.) Disconnect the mains power to the RM Eco. 2.) Close the pressure shut‐off valve. 3.) Open the vent cock for draining the system pressure to 0 bar. 4.) Check the air pressure in the expansion tank with an air pump (with pressure gauge). You can use a bicycle pump or car tyre pump. ... -

Page 19: Connection To The Mains Water Line
In order to avoid vibrations, the RM Eco must be fixed with all four screws. 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 container connection and carefully tighten with a 30 inch fixed spanner. Screw the gland screw on the other end of the flexible pipe into the stopcock mounted in the main water line. ... -
Page 20: Installation On The Intake Side
4. Protective conduit pipe 5. Floating intake 6.3.1 Installation of a protective conduit pipe The intake line must be installed in a (e.g. DN100) protective conduit pipe in order to ensure all intake lines and pipes can be accessed freely at any time. In order to avoid water accumulating in the conduit, it must be installed with > 1 % slope back towards the tank. In general, all lines carried in the protective pipe should pass through a wall bush (for example INTEWA MD100 Article number: 61 00 50), at the house. Through this bush, the intake pipe and the float switch cable are routed and sealed by a pressed rubber plate. This prevents water from outside entering the basement/garage/utility room. The wall bush must be mounted as per instructions so that the intake line is never squeezed (contraction of cross section!). ... -
Page 21: Layout Of The Intake Line
6.3.2 Layout of the intake line Only an internally reinforced flexible (resistant against vacuum) hose can be used as the intake line. This means we can use a floating intake in the tank. The internal diameter of the intake line must be at least Ø 13 mm. The INTEWA intake hose (HORIZON ½", Article No. 61 00 16) is designed for this requirement. In order to avoid potential leaks at connection points, it is strongly recommended that the intake hose (from the intake filter in the tank all the way to the RM Eco unit) should be one piece – containing no joins. Warning instructions: The internal diameter of the intake hose must be at least D=13 mm in order to obtain full volume flow. No water filter may be used in the intake line, since the gaskets are not designed for underpressure. The underpressure for intakes ... -
Page 22: Intake Line Connection
6.3.3 Intake line connection The intake line is routed through the wall into the house, and connected to the RM Eco without tension. The gland screw is to be tightened to the RM Eco connector only by hand. As the intake hose should not exert any force on the coupling to the unit, the pipe should be securely fastened to the wall with separate pipe clamps. 6.3.4 Installation of the floating intake For best water quality, we recommend the intake line in the tank is installed as a floating intake. The accessory product SAUGSAGF ½" (Article No. 21 01 33) meets this requirement. The rainwater is drawn from just below the water surface where the water is the cleanest. The integrated non‐... - Page 23 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 gasket. 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. ...

Page 24: Connecting The Emergency Overflow
6.5 Connecting the emergency overflow The RM Eco 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 ... -
