3.4.4 Connecting the hoses
The scope of delivery contains two tubings with fittings (intake tubing, drain tubing) for the
connection between the flow-through holder and the flow intake and flow drain. The intake
tubing has a shut-off clamp and the drain tubing has a backpressure valve. Connect the hoses
according to the following drawing:
The hose for the connection between the sampling point and the device as well as the hose for
the flow drain do not belong to the scope of delivery. For this purpose use hoses with the
following specifications:
• Inner diameter: 4.75 mm / 3/16".
• Outer diameter: 8 mm / 5/16".
• Flexible and opaque hose material to prevent algae growth if direct sunlight can reach the
hose.
CAUTION!
Do not connect the sensor interconnect cable with the upper part of the device now and regard
the installation order in the chapter "Electrical connections"! The reason is that you will have to
do the internal wiring at first and the connection of the sensor interconnect cable afterwards, the
reverse order could damage the device!
