2.4 Specification and Technical Notes
• The system is designed for interior use only. Maximum altitude: 2000 m.
• The relative air humidity shall not surpass 80 % rH at 31 °C or 50 % rH at 50 °C (with a linear
decline).
• Temperature: 10 °C till 50 °C
• Admissible mains voltage fluctuations: Within the range of ± 10 % of rated voltage.
• Transient overvoltage tolerated acc. to IEC 60364-4-443, max. degree of soiling: 2
• Mains cables must feature a protective conductor. In the case of cables not delivered by
Vermes Microdispensing, the guarantee for the microdispensing system is valid only up from
the interface.
• Power outlets must comply with common safety prescriptions.
• During the application, you must guarantee sufficient air circulation. For further details, refer
to Installation chapter paragraph 6.3.1, page 46.
For exact dispensing results, the temperature of the actuator system should stay below 80 °C.
Therefore, you might need cooling. Cooling is achieved by compressed air, free of fine
particles, dust, oil and condensate, quality classes 3, 4, 3 acc. to DIN/ISO 8573-1:2010.
- Solid particles: Quality class 3
max. number of particles/m³: 0.5 – 1 µm: < 90000, 1 – 5 µm: < 1000
- Water content: Quality class 4
max. pressure dew point +3 °C
- Residual oil: Quality class 3
1 mg/m³ max.
2.5 Warnings
• Handle the mains cables correctly: Always seize the cable at the plug. Never touch it with wet
hands.
• Under no circumstances connect a schuko-plug (type F, CEE 7/4) with a socket build for an
unearthed plug (type C, CEE 7/17). The system would not be grounded.
• The cable should never be squeezed or kinked. Never place the instrumentation (or any other
object) on the cable.
• Damaged cables may give rise to fire and danger caused by electricity. Inspect them visually
in regular intervals. You should exchange damaged parts at once.
• In the case of a major disturbance, disconnect the equipment immediately from the mains.
• Spare parts not delivered or recommended by the manufacturer could affect the inherent
safety of the system. The same problem arises, if the customer attempts to process
substances not admitted for the dispensing system.
• Unqualified repair work often causes major damages, sometimes even personal injuries.
Therefore, repair is reserved to our Technical Support and authorized subcontractors.
• Before removing the actuator and sensor cable, the system must be switched OFF.
• For longer interruptions, switch OFF the control unit.
• Before disconnecting the control unit from the mains, switch it OFF.
• Repeatedly switching ON and OFF the equipment may reduce the lifetime of the power unit.
• Before charging the fluid system with an aggressive, reactive or toxic substance, you have to
verify that it is compatible with all of the contacting components inside the system.
• The supply pressure at the cartridge or in the pressure tank of 7 bar resp. 100 bar (according
to the system configuration) should never be exceeded.

• If you use the valve with a heater for the nozzle unit, the temperature in that area can reach
up to 180 °C. Do not touch it during operations and afterwards only once it had enough time
to cool down.
• When cleaning the components in contact with the transported substance, you should place
the device in a safe and stable position, without being subjected to vibrations.
• To clean the actuator, a cloth not fluffy and lightly moistened (e.g. by Isopropanol) is
recommended. During the cleaning procedure, no liquid should penetrate into the actuator
itself (e.g. through the plug).
2.6 Qualifications of Operators and Maintenance Personnel
The microdispensing system together with all attached accessories should only be used by
competent personnel with an adequate qualification. They must know and understand the
content of the manual. We do suppose that the department head is aware of possible dangers,
and correspondingly assigns the tasks to persons able to execute their work in a responsible
manner.
According to DIN VDE 0105 and IEC 364 qualified personnel refers to members of the team with a
sufficient knowledge of relevant norms, directives and rules for prevention of accidents. They
need the qualification and experience necessary, so that they are in a position to realize and to
prevent possible dangers already at an early stage. Knowledge in First Aid and a direct contact to
the local emergency units is required as well.

2.7 Protective Equipment and Safety Clothing
You should always wear suitable protective equipment, whenever handling or dispensing
aggressive, reactive or toxic substances. The same is valid in the presence of a high supply
pressure.
