OPERATING MANUAL
VERSION 03/2013 ORDER NUMBER DOC 2310799
4.3 USE IN AREAS SUBJECT TO EXPLOSION HAZARDS
The pneumatic pump may be used in areas subject to explosion hazards. The following
safety regulations must be observed and followed.
4.3.1 SAFETY REGULATIONS
Safe handling of WAGNER spray devices
Mechanical sparks can form if the device comes into contact with metal.
In an explosive atmosphere:
Do not knock or push the unit against steel or rusty iron.
Do not drop the device.
Only use tools that are made of a permitted material.
Ignition temperature of the pumped material
Check that the ignition temperature of the pumped material is higher than the max.
allowable surface temperature.
Medium supporting atomizing
To atomize the material, use only weakly oxidizing gases, e.g. air.
Surface spraying, electrostatics
Do not spray device parts using electrostatic equipment.
Cleaning
If there are deposits on the surfaces, the device may form electrostatic charges. Flames or
sparks can form during discharge.
Remove deposits from the surfaces to maintain conductivity.
Only use a damp cloth to clean the device.
4.3.2 OPERATION WITHOUT FLUID
Avoid running the pump so that it sucks in air (without uid inside). The air, combined with
the vapor of ammable uids, can generate internal areas with an explosion hazard.
Periodically check that the pump is working smoothly, paying special attention to the
presence of air in the pumped uid, which may be caused by damaged packings.
Avoid operating the pump with damaged packings.
Ensure that the separating agent container is lled with su cient separating agent.
