To ensure flawless usage of our devices, the following points must be observed during
assembly and installation:
4.1
Mechanical assembly
Take the appropriate measures to prevent freezing of the medium. Should the device later be
subjected to an ambient temperature <4°C, no operation with pure water may be performed.
Frost damage may be caused by water remaining in the device.
Note the permitted installation positions from the product information.
The device may never serve as a fixed point.
The connector flanges/threads must be compatible.
A filter should be provided for heavily spoiled media.
Take note of the stated operating pressure as well as the permissible temperature range.
Thermal expansion of the pipework must be balanced out by compensators.
The device can be aligned horizontally or vertically.
The direction of flow is indicated on the device by an arrow. The arrow points in the direction of
flow. With the HV device the flow in both directions is possible.
When tightening the screw joint the connection must be locked so that no torque is transferred to
the body.
This equipment is designed for low-viscosity media. Highly viscous medium delays the
start of rotor/turbine.
5.1
Activation
Before activation note the limit values stated in the product information, such as for pressure
stage, temperature range or maximum permitted flow.
If present, the transport lock must be removed.
When operating with protective covers, remove them immediately before assembly.
Rinse the pipe system before assembly to remove any spoiling.
Observe the direction of flow. This is indicated on the device with an arrow and must run parallel
to the pipe axis after assembly.
Properly tighten the device during assembly.
Endurance must be assessed with aggressive media.
To avoid heavy pressure surges we recommend that you fill and ventilate the system before
activation. Pressure surges may not exceed the value of PN/PS.
Ensure that assembly is conducted properly.
