1. Introduction and scope of application Congratulations on purchasing your RAINMASTER Favorit (RM Favorit). The RM Favorit is specially designed for rainwater and greywater harvesting in large single family dwellings, multiple family dwellings and in commercial and industrial applications. The maximum installation height for toilets, washing machines and other applications, above the RM Favorit, is 15 m.
(the regular refreshing of water in the supplemental supply) are automatically controlled by the unit‘s built-in pump-controller. Rainwater module RAINMASTER Favorit Mains water connection Pressure line set with air vent and stopcock...
2. Safety instructions This installation and operating manual is to be read carefully before installing the device. The instructions specified here are to be accurately followed, as failure to do so may lead to rejection of any warranty claim. This also applies to modifications to the RM Favorit. Moreover, any modification of the supplemental supply device or the electronic inside the unit will immediately nullify the warranty.

4.2. Dimensions of the intake line In practice, the self-priming function of the pump depends due to decrease in pressure (pipe friction, suction level) only in a certain range. In this operating range, the pump can evacuate the air out of the suction line (for example, with initial start-up operation).
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 fulfils the requirements of the following EU directives:...
5. Overview of components The RM Favorit has a modular design. Each component can be separately changed. 5.1 Components of the pump-controller The pump-controller (see Chapter 4.1) monitors the pressure and volume flow rate in the pressure line system. The direction of flow is marked by an arrow on the housing.
Wiring of the pump controller 5.2 Components of the basic controller The unit’s basic controller (see chap. 4.1) is located in the terminal box (position [1]) and here all the electronic components of the RM Favorit are connected, along with the motor condenser (position [2]) required for starting the motor.

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 valveis closed (backside of the container). The water level can be adjusted by twisting the black lifting body (5).
6. Installation instructions 6.1 Wall mounting The RM Favorit is mounted on a wall with the supplied wall bracket. The lid and lateral distances indicated should adhered when mounting, provide clear maintenance access. The RM Favorit is fixed horizontally with Ø10 mm raw plugs and screws.
The provided rubber clamping device is to be fit on the back side of the unit in the lower corners. The unevenness of the wall can be balanced by various screwing depths. 6.2 Connection to the mains water line The connection to the mains water supply is done with the provided flexible hose and stopcock. Screw the gland screw into the container connection and carefully tighten with a fixed spanner.
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 internal diameter of the intake line must be at least Ø 26 mm. The INTEWA intake hose (SDS 1“, Art.-Nr. 61 00 25) 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 Favorit unit) should be one piece –...
6.3.3 Intake line connection The intake line is routed through the wall into the house, and connected to the RM Favorit. The gland screw is to be tightened to the RM Favorit connector. 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.
6.4 Installation of the pressure line set The pressure line set (see scope of delivery) establishes the connection between the pump and pressure line system. The pressure line set is connected to the pump controller The flexible hose and the shut-off valve then connect to the pressure line set and the pressure line.

Note: 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 RM Favorit.
6.6 Installation and adjustment of the float switch 1. Float switch cable 2. Wall bush 3. Protective conduit pipe (slope > 1%) 4. Floating intake 5. Counter weight 6. Float switch The float switch cable is housed in the same protective conduit as the intake line, for easy access and protection from damage.
7. Start up and use 7.1 Start-up in mains water mode Check that all lines are connected. Select maintenance mode = Switch position II. Open the mains water line stopcock so that the supplemental supply container is filled with water. Note: In maintenance mode the pump primed with water automatically over the mains water tank.
Open the pressure shut-off valve and release the air from the (house) line (e.g. by pressing the toilet flush several times or open the garden tap.). Close all the consumers. The pump will now automatically switch off when the maximum system pressure is reached. 7.2 Start-up in rainwater mode Note: If the mains water start-up operation is not successful on the...
Open the air vent (hold a bucket of water under the air vent) and start the pump by plugging in the mains power. The motorised ball valve will move into the “rainwater“ intake position. Let the water run from the air vent into the water bucket until there is no more sign of bubbles (a clear stream), meaning that all the air has been removed from the suction line.
7.3.1 Automatic mode (Switching position I ) Automatic mode is the normal operating mode, and is selected by Switch position I. In this mode, the unit automatically switches from rainwater to mains water if the float switch detects the rainwater tank is empty. Two operating modes can be used according to the two positions of the float switch, both of which are indicated by the display of the motorized valve (see chapter 5.4).
8. Trouble shooting in case of problems Description of error Cause Solution The pump is not starting and a.) Air in intake line, as float a.)

The RAINMASTER D 24 is a fill level unit for water tanks up to 3 m water depth. It can be installed everywhere in the house and is a perfect complement for the RAINMASTER Favorit rainwater unit. RMF-LP, Art.-No. 22 00 76 Charging pump for boosting the water intake line pressure from higher intake depths or longer intake lengths.
