2. Symbols and marks used
Warning

user if the instructions are not followed.
Caution
Indicates possible damage to the visual level indicator if the instructions are not

Safety information
For equipment intended for use in potentially explosive atmospheres in accordance
with the European directive 2014/34/EU (ATEX) or IECEx.
This information is applicable in addition to all other information.
3. Safety information and warnings
The manufacturer accepts no liability for damage caused as a result of failure to comply with the safety
information and warnings.

Risk of burning! Working on hot visual level indicators may result in physical injuries and burns.
The surfaces of the standpipes and the process connections may become hot. Allow the tank to
cool to the ambient temperature before working on the visual level indicator. Wear suitable
protective equipment (gloves, face guard, possibly breathing apparatus). Keep a sufficient
distance away while the machine is in operation.

Visual level indicators run at excessive pressure carry pressure-related risks. Depressurise the
tank before working on the visual level indicator and observe the information in the European
Pressure Equipment Directive 2014/68/EU.

When opening the visual level indicator, bear in mind that the fluids and gases it contains could
be hazardous to health. It is imperative that you comply with the safety data sheets for the
process liquids and gases used.

The visual level indicator may stop working due to the float gauge being blocked, and this may go
unnoticed. If you are unsure about the fluid level shown, the visual level indicator should be
tested using a different method (see “Troubleshooting”)

If you suspect that there is a malfunction or determine that there is one, this must be rectified.

Only use the visual level indicator if you have read and understood this manual in full.

This manual must also be accessible for later users.

Keep magnetic and magnetisable parts (magnets, structural steel, iron wire or iron clips, etc.)
away from the visual level indicator. The same applies for strong electromagnetic fields
(transformers, welding equipment, etc.). Both can interfere with the magnetic force of the
magnets inside the visual level indicator and lead to the gauge and any attached accessories
(switch, transducer) malfunctioning and dropping out.

Replace damaged or faulty components with original replacement parts.

Solvents may dull or crack any plastic parts used. Clean the indication rail with soapy water or a
plastic cleaner.

The visual level indicator must not be installed under mechanical tension.

The visual level indicator must not be used to mechanically reinforce the tank or the system.
