Particulate and gaseous contamination specications
The following table denes the limitations that help avoid any equipment damage or failure from particulates and gaseous contamination. If
the levels of particulates or gaseous pollution exceed the specied limitations and result in equipment damage or failure, you may need to
rectify the environmental conditions. Re-mediation of environmental conditions is the responsibility of the customer.
