• Do not modify the equipment without approval from an Ex-approved Xylem
representative.
• Only use original Xylem spare parts that are provided by an Ex-approved Xylem
representative.
• The thermal contacts that are fitted to the stator windings must be connected correctly to
a separate motor control circuit and in use. The thermal contacts shall be connected to a
monitoring device, which disconnects the power supply immediately upon activation. This
action prevents the rise of temperatures above the temperature value for the approval
classification.
• The width of flameproof joints is more than the values specified in the tables of the EN/
IEC 60079-1 standard. For information contact the manufacturer.
• The gap of flameproof joints is less than the values specified in Table 2 of the EN/
IEC 60079-1 standard. For information contact the manufacturer.
• It is NOT allowed to repair the flameproof joints.

The screws used for the assembly of the various parts of explosion-proof enclosures must
be of quality higher than or equal to A4–80.
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 representative.
When you install or maintain explosion proof products, always comply with the directive and
applicable standards (for example, IEC/EN 60079–14).
Minimum permitted liquid level
See the dimensional drawings of the product for the minimum permitted liquid level
according to the approval for explosion proof products. If the information is missing on the
dimensional drawing, the product must be fully submerged. 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. Examples of condition-monitoring
devices include, but are not limited to, the following:
• Level indicators
• Temperature detectors in addition to the stator thermal detectors
Any thermal detectors or thermal protection devices delivered with the pump must be
installed and in use at all times.
The site owner is responsible for selection, installation, and proper maintenance of functional
monitoring equipment for motor protection.
