VERSION 12/2018
4.2.5 CLEANING AND FLUSHING
Hazard due to cleaning and flushing!
Explosion hazard and damage to the device.
Preference should be given to non-ignitable cleaning and flushing agents.
When carrying out cleaning work with flammable cleaning agents, make sure that all
equipment and resources (e.g., collection tank, funnel, transport cart) are conductive
or static dissipative and grounded.
Observe the specifications of the lacquer manufacturer.
Ensure that the flash point of the cleaning agent is at least 15 K above the ambient
temperature or that cleaning is undertaken at a cleaning station with technical ventilation.
Never use chloride or halogenated solvents (such as trichloroethane and methylene
chloride) with devices containing aluminium or galvanized/zinc-plated parts. They may
react chemically thus producing an explosion danger.
Take measures for workplace safety (see Chapter 4.1.2).
When commissioning or emptying the device, please note that:
– depending upon the coating product used,
– depending on the flushing agent (solvent) used.
an explosive mixture may temporarily exist inside the lines and components of equipment.
Only electrically conductive tanks may be used for cleaning and flushing agents.
The tanks must be grounded.
An explosive gas/air mixture forms in closed tanks.
Never spray into a closed tank when using solvents for flushing.
External Cleaning
When cleaning the exterior of the device or its parts, also observe the following:
Relieve the pressure from the device.
De-energize the device electrically.
Disconnect the pneumatic supply line.
Use only moistened cloths and brushes. Never use abrasive agents or hard objects,
and never spray cleaning agents with a spray gun. Cleaning the device must not
damage it in any way.
Ensure that no electric component is cleaned with or immersed into solvent.
