The set-up location of the degassing equipment must guarantee that the operation, servicing, testing, maintenance, assembly and disassembly
can be performed regularly, without obstruction and safely. The surface forming the installation area for the equipment must ensure stability
and support. Bear in mind that the maximum possible forces comprise the deadweight including the water fill.
If stability cannot be guaranteed, there is a danger that the unit will tip over, or move under load and, as a consequence, cause injury to persons
and malfunctions.
The ambient atmosphere must be free of electrically-conductive gases, high concentrations of dust and aggressive vapours.
There is the risk of explosion if any combustible gases are present.
Depending on the process, the water temperature can rise to 90 °C on the unit; in case of improper operation, it can exceed 90 °C.
There is thus a danger of injury to persons through burns and / or scalding.
Flooded equipment must not be operated. If electrical equipment short circuits, persons or other beings in the water will be electrocuted.
Furthermore, there is a danger of malfunction and partial or irreparable damage to individual components due to
water saturation and corrosion.
4.8
Noise reduction
Ensure that the noise emissions in the installation are minimised by using state-of-the-art technology (e.g. by means of sound-absorbent pipe
fittings).
4.9
EMERGENCY-STOP / EMERGENCY-OFF
The Emergency Stop function required under the terms of European Directive 2006/42/EC is provided by the respective main switch on the
control unit.
If further safety chains with Emergency Shut-Down devices are required by the configuration or nature of operations of the heat generator,
these are to be installed on site.
4.10 Personal protective equipment (PPE)
PPE must be used when carrying out potentially dangerous work and other activities (e.g. welding), in order to prevent or minimise the risk of
personal injury if other measures cannot be taken. These must comply with the requirements specified by the main contractor or operator of
the operations room or the site in question.
If no requirements are specified, to operate the automat no PPE is required. Minimum requirements are well-fitting clothing and sturdy, closed
and slip-proof footwear.
Other services require the protective clothing and equipment necessary for the activity in question (e.g. transport and assembly: rugged,
close-fitting work clothing, foot protectors [safety shoes with toe caps], head protection [safety helmet], hand protectors [protective gloves];
maintenance, repair and overhaul: rugged, close-fitting work clothing, foot protectors, hand protectors, eye / face protector [safety goggles]).
4.11 Exceeding permitted pressure / temperature levels
The object of the degassing system is to ensure that the equipment cannot exceed the permissible operating overpressure or permissible
medium temperature (heating medium). Excess pressure and temperature may lead to component overload, irreparable damage to
components, loss of function and, as a result, to severe personal injury and damage to property. Regular checks / inspections of these
safeguards must be carried out.
4.12 System water
Non-flammable types of water without solids or fibrous components that do not present a danger to operational readiness with their
constituents, and will not damage water-conducting components of the degassing equipment (e.g. pressurised components, pumps and motor
position valves) or have undue influence on its working. Components conducting process water are pipelines, hoses to the vessel, device and
system connections, and their casings, sensors, pumps and vessels. Operation with improper media can lead to impaired function, damage to
components and, as a consequence, to serious personal injury and damage.
The operating medium must meet the requirements of VDI 2035! Desalinated water must have a conductivity between 10 and 100 µs/cm with a
pH value that does not exceed the allowable limits according to VDI 2035 depending on the material used.
4.13 Safeguards
The equipment supplied is equipped with the required safety devices. To test their effectiveness or restore the set-up conditions, the equipment
must first be taken out of service. Taking the system out of service implies that power should be cut and hydraulic connections blocked, to
prevent accidental or unintentional re-connection.
4.13.1 Mechanical hazards
The fan-wheel casing on the pump protects operators from personal injury from moving parts. Before commissioning, check that it is fit for
purpose and fixed in place.
4.13.2 Electrical hazards
The protection class of the electrically operated components prevents injury to persons through potentially fatal electrocution.
The protection class is at least IP42 (4: Protected against access with a wire; 2: Protection against dripping water if the casing is angled up to
15°.) The control unit cover, the cover of the pump feed, the motor ball valve connection, the threaded cable glands and the valve connector
plugs must be inspected for effectiveness prior to commissioning. Check that the ground connections are tight. The installed pressure sensors,
the pressure switch and the temperature sensor are operated with protective low voltage.
Avoid welding work on additional equipment that is electrically connected to the Vacumat Eco. Stray welding currents or an improper earth
connection could lead to the danger of fire and the destruction of parts of the unit (e.g. the control unit).
