OPERATING MANUAL
Several liquids have a high expansion coeffi cient. In some cases their volume can rise with
consequent damage to pipes, fi ttings, etc. and cause fl uid leakage.
When the pump sucks liquid from a closed tank, ensure that air or a suitable gas can
enter the tank. Thus a negative pressure is avoided. The vacuum could implode the tank
(squeeze) and can cause it to break. The tank would leak and the liquid would fl ow out.
The pressure created by the pump is a multiplication of the inlet air pressure.
4.2.4
CLEANING AND FLUSHING
Relieve the pressure from the device.
De-energize the device electrically.
Preference should be given to non-fl ammable cleaning and fl ushing agents.
When carrying out cleaning work with fl ammable 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 specifi cations of the lacquer manufacturer.
Ensure that the fl ash 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.
Take measures for workplace safety (see Chapter 4.1.3).
When commissioning or emptying the device, please note that an explosive mixture
may temporarily exist inside the lines and components of equipment:
- depending on the coating product used,
- depending on the fl ushing agent (solvent) used,
explosive mixture inside the lines and items of equipment.
Only electrically conductive tanks may be used for cleaning and fl ushing 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 fl ushing.
External cleaning
When cleaning the exterior of the device or its parts, also observe the following:
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 gun. Cleaning the device must not damage it in any
way.
Ensure that no electric component is cleaned with or immersed into solvent.
Which cleaning agent is used to clean the spray gun depends on which parts of the
spray gun have to be cleaned and which product has to be removed. When cleaning the
spray gun, only use non-polar cleaning agents to prevent conductive residues on the
surface of the spray gun. Should it however, be necessary to use a polar cleaning agent,
all residues of this cleaning agent have to be removed by using a non-conductive and
non-polar cleaning agent, once the cleaning is fi nished.
