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 RM Favorit is compatible with the following combinations:
Toilet / Urinal:
You can connect several toilets and urinals.
Washing machine:
You can connect several washing machines.
Garden / Cleaning:
You can connect all types of garden hoses and sprinklers as well as cleaning
devices, in line with the maximum pump flow rate of RM Favorit 20 or
RM Favorit 40 units.
Note:
A drip irrigation system may require a special layout in combination with an
expansion vessel.
Note:
The sizing of the system, with respect to the required maximum volume flow, is governed in Germany by
regulation DIN 1988-3.

1.1 Modes of operation
Automatic mode
In Automatic mode, the pump carries rainwater from the tank into the home and onto respective
applications (e.g. toilets etc.). If the tank is empty, this is detected by the float switch in the tank, which
instructs the electronic 3/2-way ball valve to change to the mains water mode. The rainwater intake line is
then blocked and the required mains water is sourced from the built-in supplemental supply container
inside the RM Favorit. After it rains, and the tank is topped-up with rainwater again, the float switch
detects this and the electronic 3/2-way ball valve switches back to the rainwater intake setting.
Maintenance mode
In Maintenance mode, the electronic ball valve stays permanently switched to mains water mode, and the
house is continuously supplied with mains water from the supplemental supply container inside the
RM Favorit.
In both working modes, the pump is switched on and off by means of the built-in pressure switch. The
anti-dry running protection of the pump, and the stagnation protection of the supplemental water supply
(the regular refreshing of water in the supplemental supply) are automatically controlled by the unit‘s
built-in pump-controller.

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.
The user is responsible for compliance with safety and installation regulations. Only the original provided
packaging is to be used for transportation of the equipment.
The emergency overflow of RM Favorit must always be connected.
Installation of the mains water line must only be carried out by an authorized installation company.
The RM Favorit internal housing for live electrical components shall only be opened by a
qualified electrician.
The electrical circuit used to power this device must be protected by a 16A circuit breaker. Likewise, an
ELCB (earth-leakage circuit breaker), with a maximum operating current of 30 mA, is to be used.
The operator is responsible for the compliance with safety regulations and for following these installation
guidelines.

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 performance curve of the intake line
indicates the dependence of intake length on the intake level. The determined value is above the
represented intake line in the diagram. If the intake point is below the intake performance line, then a
charging pump (optional accessory RMF-LP) is used to ensure the intake process proceeds reliably and
with sufficient safety.
Note: The charging pump boosts the water intake pressure, so that an intake level of up to 3 m high can
be attained. This means that, the performance curve moves 3 m parallel towards down.
Sample dimensions:
Example A:
Length of suction pipe: = 12 m
Intake level: = 2.40 m (Height difference between deepest intake level and pump)
o.k. because it’s above the performance curve
Example B:
Length of suction pipe: = 18 m
Intake level: = 3.20 m (Height difference between deepest intake level and pump)
not o.k. because it’s below the performance curve
RMF-LP (Article No: 22 00 76) charging pump is required, in order to boost intake pressure to meet
the requirements)

4.3 Standards, Directives, tests
The RM Favorit meets the DIN 1989-4 “Components for Control and Supplemental Supply“ standards 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 RM Favorit.
