Installation instructions
The standard model of the pump is only approved for in-
stallation in dry rooms in a non-aggressive atmosphere,
at temperatures b2°C and +40°C and at permit-
ted humidity until approx. 90%.
Protect the pump against any sources of heat and against
the direct irradiation of sun and ultraviolet light
For dimensions of the pump connections and fixing holes,
see Fig. 04/05, Table. 02/03
CAUTION !
When the R/RS 204.1 is installed next to a pump of series
C/CS 204.1 or C/CS 409.2 a minimum distance of 100 mm
between the pumps (motor housings) has to be kept!
Install the pump in such a way that there is no vibration
and no tension and that it is aligned precisely.
Install the pump at the optimum possible operating height.
Mount the pump in such a way that the valves are verti-
cal.
Ensure that there is sufficient space around the pump
body and the suction and pressure valve so that these
parts may be easily dismantled, if required.
Mount the pump in such a way that electronics, operating
panel and electric connections are easy accessible.
Design the nominal diameters of the downstream pipes
and of the connections built into the system to be the
same size or larger than the nominal inlet and outlet di-
ameters of the pump.
To check the pressure ratios in the pipe system, we rec-
ommend to provide for connections for pressure gauges
(e.g. manometers) near the suction and pressure sockets.
Drain cocks are to be provided.
Prior to connecting the pipes, remove the plastic caps on
the suction and pressure sockets of the pump. (see
Fig.15).
Check that the fixing screws for the pump body are tightly
fitted and, if necessary, retighten.
With RS pumps or pumps with manual venting, connect a
hose for reflow of the pumped medium.
CAUTION !
The pump is designed for operation in non-hazardous ar-
eas!

Connect pipes to the pump in such a way that there are
no forces acting on the pump, such as e.g. misalignment,
weight or stress of the pipe.
Keep the suction lines as short as possible.
Use pressure- and medium-resistant hoses / pipes.
All pipes and containers connected to the pump must
comply with the regulations and must be cleaned, ten-
sion-free and intact.
CAUTION !
If toxic, crystallizing or corrosive liquids are conveyed the
pipe system is to be equipped with facilities for emptying,
cleaning and rinsing with an appropriate medium, if nec-
essary.
CAUTION !
Mount the solenoid diaphragm pump in such a way that
leaking medium cannot cause any damage.
