4.2.6 TOUCHING HOT SURFACES
De-energize the unit electrically.
Disconnect the pneumatic supply line.
Relieve the pressure from the unit.
Ensure that the flash point of the cleaning agent is at least 5 K above the ambient
temperature.
To clean, use cloths and brushes moistened with solvent. Never use hard objects or
spray on cleaning agents with a gun.
An explosive gas/air mixture forms in closed containers.
When cleaning units with solvents, never spray into a closed container.
Ground the container.
When preparing or working with paint and when cleaning the unit, follow the working
instructions of the manufacturer of the paints, solvents and cleaning agents being
used.
Take the speci ed protective measures, in particular wear safety goggles, protective

Several liquids have a high expansion coe cient. In some cases its volume can rise with
consequent damage to hoses, ttings and cause uid leakage.
When the pump sucks liquid from a closed container, ensure that air or suitable gas can
enter the container to avoid a vacuum being generated in the container itself. So that a
negative pressure is avoided. The vacuum could implode the container (squeeze) and can
break. The container would leak and the liquid ow out.
The pressure ratio is 1:1. Therefore the pressure generated by the pump is equal to the
input air pressure.
