P2.x ATEX
4.1.1 Outdoor installation
The sample gas pumps were not specifically designed for outdoor setup. The operating and environmental conditions are cru-
cial for the required types of protection and any additional measures required, such as:
– adequate protection from the weather
– Adjusting the maintenance intervals (e.g. cleaning and replacing wear parts)
Use suitable measures and regular inspections to prevent damage to the equipment from e.g.:
– Corrosion
– Sunlight (temperature peaks and damage from
UV rays)
– Moisture from condensation (e.g. due to rapid temperature changes or downtimes)
– Icing
– Insects and microbes
– other animals, e.g. martens, etc.
Please remember that all technical operating parameters of the equipment must also be met with outdoor installation. Specific-
ally:
– Maximum or minimum operating temperatures
– Degree of protection
4.2 Installation
