4 Safety provisions
Any work on or with the device may be performed only by qualified personnel who are familiar with the applicable
regulations on operating pressure regulators and/or pressure containers.
If disassembling safety equipment is required for installation, it must be assembled and inspected immediately once
the work has concluded.
Do not exceed the operating pressure. It is specified on the nameplate of each device.
When using the device, the provisions regarding the filling material must be followed.
Natural regulations regarding usage and test intervals must be followed.
5 Material resistance
Since the operator chose the material, the supplier cannot provide any guarantees regarding material resistance. It is
the operator’s responsibility to ensure that the material of the devices, including seals and add-on components (e.g.,
pressure gauges, pilot regulator, etc.) are adequately resistant against the medium.
6 Startup
6.1 Before installation
Before installation, perform a visual inspection on the device to determine any transport damage. The device’s
performance data must be reviewed (max. inlet pressure, secondary pressure, etc.).
The values noted on the nameplate are the values measured in our functional test.
The resistance of the materials has to be checked (see the corresponding chapter of this operating manual).
Newly installed pipelines must be fully rinsed clean to eliminate mechanical residues. It must be ensured that the
pressure regulator is connected at the local equipotential bonding, either through an adequate and permanent
connection to metallic pipes or via a direct connection to local equipotential bonding.
6.2 Installation
Always install the low pressure regulator as close as possible to the process tank or consumer within non-turbulent
flow.
Be mindful of the flow direction! (Marked on the housing with an arrow). Otherwise, there is the risk of damaging
the pressure regulator.
6.3 Assembly position and installation
Take note of the diaphragm installation position! (Horizontal diaphragm or vertical diaphragm). Sealed
devices are set to the desired pressure according to the ordered position If the devices are configured by the user,
then this also must take place in the subsequent installation position.
The preferred mounting position and/or position of the diaphragm is as follows according to device type:
- ZM-R15, 25:
Horizontal diaphragm housing (vertical: alternatively permissible).
Assembly with the spring dome facing down is permissible only upon consultation.
- LPR25:
Vertical diaphragm housing (horizontal: alternatively permissible).
Assembly with the spring dome facing down is permissible only upon consultation
