Type 8006, 8702
Danger from the outflow of operating fluid
Respect the prevailing regulations on accident prevention and
safety relating to the operating fluids used.
various dangerous situations
To avoid injury take care:
• to prevent unintentionally switching on the power supply.
• to ensure that installation and maintenance work is carried out
by qualified, authorized personnel in possession of the
appropriate tools,
• to keep the device away from any highly flammable materials or
fluids and avoid any contact with bare hands,
• to guarantee a defined or controlled restarting of the process,
after an interruption to the power supply or medium supply,
• to use the device only if in perfect working order and in compliance
with the instructions provided in the instruction manual,
• to observe best industry practice for the installation and use of
these devices,
• not to use MFM / MFC types 8006, 8702 / 8626, 8712 for
controlling and/or measuring the flow-rate of fluids which contain
particles (particle size > 25 µm),
• not to operate the device without the stainless steel mesh filter
disc installed at the factory,
• not to operate the device in a mounting position which deviates
from the calibration conditions,
• not to operate the device with higher pressures than the
specified tightness pressure (MFC) respectively calibration
pressure (MFM),
• not to subject the device to mechanical loads (e.g. by placing
objects on top of it or by using it as a step).
• not to make any external modifications to the device. Do not
paint or varnish any part of the device. Do not feed any other
fluids into the system other than the designated operating
fluid indicated on the device name plate. Exception: agent for
cleaning and decontaminating the device (see also section
„9.2.1“). In doing so, observe the compatibility of the materials
used for the device. You will find a chemical compatibility chart

note
elements / components sensitive to electrostatic discharges
• This device contains electronic components sensitive to
electrostatic discharges. They may be damaged if they are
touched by an electrostatically charged person or object. During
electrostatic discharge, they will become defective immediately
or will fail when energized.
• To minimize or even avoid all damage due to an electrostatic
discharge, take all the precautions described in the standards
EN 61340-5-1 and 5-2.
• Also ensure that you do not touch any of the live electrical
components.
