If loss of cooling water creates a significant risk, then the water flow
must be monitored externally by the process equipment.
When the EMO is activated, some internal electrical parts are energized
and water cooling line and N
2
purge line are always supplied.
Risk of electrical shock in case of contact.
Before any intervention, disconnect main electrical cable, water inlet and
outlet quick connectors and N
2
purge connector.
Lock out/tag out (LO/TO) water and N
2
supplies.
The end user needs to provide a dedicated source of water and Nitrogen
equipped with a manual valves that can be locked out within 10 feet of
the tool.
The products are designed to avoid subjecting users to heat hazards.
However, specific operating conditions may exist that require extra
caution from users due to the high temperatures (outer surfaces > 70 °C
on the exhaust pipe),
Wear protective gloves and leave the pump to cool before working on
the product.
The user and /or OEM are ultimately responsible for operating the
equipment in a safe manner. The manufacturer has no control over the
types of gases exposed to this pump. This is the user and/or the OEM’s
responsibility to follow the necessary safety requirements.
Frequently process gases are toxic, flammable, corrosive, explosive and/
or otherwise reactive.
Toxic gases can cause serious injury or death. Operators and users must
take the appropriate safety recommendations to prevent injury. Consult
the responsible department for instructions and safety information.
Hazardous gases through the pump can cause serious injury or death.
It’s mandatory by regulations to connect the pump’s exhaust to a facility
hazardous gas exhaust system which incorporates appropriate filters,
scrubbers, etc. This system must meet all air and water regulations.
Check that pump is correctly connected to the equipment ( B 60).
