HYDAC FILTER SYSTEMS GMBH Setting up / assembly / integration of the filter unit | 5 5 Setting up / assembly / integration of the filter unit Observe the following notices for mounting the filter unit. – Place the filter unit horizontally on a stable, even and hori- zontal surface.
5 | Setting up / assembly / integration of the filter unit HYDAC FILTER SYSTEMS GMBH 5.1 Avoiding siphoning If there is a height difference (ΔH) between the suction side and pressure side container/system, the lower line can develop a suction effect and trigger the siphoning effect between the communicating containers/systems.
HYDAC FILTER SYSTEMS GMBH Setting up / assembly / integration of the filter unit | 5 5.2 Measure or display dynamic pressure / differential pressure If pressure is measured in a hydraulic system, the type of mea- surement such as dynamic pressure or differential pressure as well as the measurement point is critical, as shown in the following diagram.
5 | Setting up / assembly / integration of the filter unit HYDAC FILTER SYSTEMS GMBH 5.3 Avoiding the mixing of oils - Emptying the filter unit If you want to use the same oil for operation as in the previous operation, it is not serious if the oils are mixed.
HYDAC FILTER SYSTEMS GMBH Setting up / assembly / integration of the filter unit | 5 5.4 Making the electrical connections Depending on the version, the filter unit has different drive mo- tors (different voltage / output / number of phases, etc.). Follow the instructions in the next section to electrically connect the fil- ter unit.
