Hydraulic Installation

IMPORTANT
• Observe the maximum operating parameters for the whole in-line probe
housing (e.g. pressure, temperature, flow)! Take into account the lowest
maximum operating parameters of the in-line probe housing components and
sensors (please refer to the individual operating manuals)! Please also note the
temperature dependence of the maximum pressure!
• Assemble the in-line probe housing in such a way that the modules cannot
drain off and fill with air, even when the water is stationary!
• There must be stop valves in the in-flow and out-flow of the module block!
• When assembling the in-line probe housing, take steps to prevent positive
suction pressure from building up inside it!
• When installing the in-line probe housing in a free flow system, lay the out-flow
cable in an ascending S-shape.
• Install a filter in the supply cable of the in-line probe housing if the water is
contaminated (take into account any depletion caused by the filter).
• If the in-line probe housing is installed in a fixed pipe, the power supply must
be switched off before the module block is fitted.
Connect the in-flow cable to the ball valve connector set
Connect the out-flow cable to the connector set on the out-flow side.
