Dangerous substances
For dangerous media such as e.g. Oxygen, Acetylene, flammable or toxic substances as
well as refrigeration systems, compressors, etc. must comply with the relevant regulations
beyond the general rules.
Qualified Personnel
The DOZ03, DOZ05 and DOZ07 devices may only be installed by trained, qualified
personnel who are able to mount the devices correctly. Qualified personnel are persons,
who are familiar with assembling, installation, placing in service and operating these
devices and who are suitably trained and qualified.
Inward Monitoring
Please check directly after delivery the device for any transport damages and deficiencies.
Additional with reference to the accompanying delivery note the number of parts must be
checked.
Claims for replacement or goods which relate to transport damage can only be considered
valid if the delivery company is notified without delay.
Requirements for use in hazardous areas:
Reed switch: Connection to intrinsically safe electric circuit (simple electrical equip-
ments must be operated intrinsically safe with a suitable barrier according to
EN 60079-11).
Equipotential bonding has to be ensured upon the pipe system.
Meters with plastic housing: do not clean the meters with a dry cloth as this would
cause electrostatic charge.
The fluid conductivity must be higher than 1000 pico/Siemens/meter to avoid
electrostatic charges.
Explosion and fire hazards
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous
condition and result in an explosion or fire and cause serious injury.
Be sure the fluid system is properly grounded. See your pump instruction manual
for details.
If there is static sparking or if you feel an electric shock while using the meter, stop
dispensing immediately. Identify and correct the problem before continuing.
Provide fresh air ventilation. This will avoid the build-up of fumes from the fluid
being dispensed.
Do not smoke while dispensing flammable fluids.
Keep the dispensing area free of debris including solvents, rags and spilled
gasoline.
