Installation
1
General attention points
·
Use the equipment in an environment with a stable ambient pressure and temperature.
·
Place the assembly on an even, level surface with a rigid and stable underground.
·
The construction or surface to which the equipment is mounted should be able to support the dimensions and
weight of the entire assembly.
·
Preferably install the ES-FLOW™ in a horizontal pipe segment or a segment where the flow direction is upward.
·
Where applicable, use the provided mounting holes to fixate the equipment. Consult the according dimensional
drawing(s) for the exact sizes and locations of the mounting points.

Fluid connections
a. Install the control valve downstream from the flow controller. Observe
the flow arrow on the measuring tube of the ES-FLOW™.
b. When coupling the instrumentation, follow the installation instructions
in the related manuals (see page 2).
c. At each Tri-Clamp connection, make sure to put a gasket between the
coupling flanges.
d. Follow the instructions of the manufacturer of the Tri-Clamp clamps.
·
Do not apply fluid pressure until all required fluid connections and electrical connections have been made.
·
Check the fluid system for leaks before applying pressure, especially when using hazardous media (e.g. toxic or
flammable).
3
Pneumatic connections
a. Screw the push fitting into the control valve body.
b. Connect the pressure regulator and the control valve using the flexible tube.
c. Connect the pilot valve to the pneumatic gas supply following the installation instructions in the manual of the
pilot valve (see page 2).
·
The tube between the pressure regulator and the control valve should be as short as possible.
·
Make sure that the pneumatic pressure meets the specifications of the tube, control valve and pilot valve.
·
For the required actuation pressure of the control valve, check the according manual (see page 2).
4
Electrical connections
·
Use the supplied actuation cable to connect the flow controller with the pilot valve.
·
Connect the ES-FLOW™ electrically as described in the according manual (see page 2).
Always isolate electrical power before connecting or disconnecting equipment.
Maintenance
In order to keep the equipment in optimal shape, it needs regular preventive maintenance. Especially the control valve
contains some mechanical parts that are subject to wear and tear.
Follow the service and maintenance instructions in the according manuals (see page 2).
Before loosening fluid connections or disassembling/reassembling any parts of the system (electrical or fluid related),
make sure that:
·
the fluid system is brought to atmospheric pressure.
·
the equipment is isolated from the electrical power source.
