Guidelines for compliance
Compliance is fulfilled only when you operate the unit within its intended use. Do not
change the conditions of the service without the approval of an Ex-approved Xylem

ATEX-approved products must be fully submerged according to the ATEX approval. Level-
sensing equipment must be installed if the product can be operated at less than the
minimum submersion depth.
Monitoring equipment
For additional safety, use condition-monitoring devices. Condition-monitoring devices
include but are not limited to the following:
• Level indicators
• Temperature detectors
Environmental safety
