When the main switch is set to “0“, the part supply between the power
plug and the main switch remains energized.
Risk of electrical shock in case of contact.
Disconnect the main electrical cable before servicing.
Hazardous voltage enclosed.
Voltage or current hazard sufficient to cause shock.
Disconnect and lockout power before servicing.
Any intervention must be done by trained personnel only.
Lock out/tag out (LO/TO) device.
In order to properly secure the pump for installation and/or maintenance,
it is required to lock out/tag out the pump properly in accordance with
OSHA requirement 29 CFR.1910.147.
For P and H pumps only.
If loss of purge flow creates a significant risk, then the purge flow must
be monitored externally and a response to loss of purge flow must be
provided by the process equipment and interlocked if necessary.
If pyrophoric materials above the LEL are sent to the pump then nitrogen
should be supplied at a rate to ensure that concentration is diluted to be
below the LEL, in addition an interlock should be provided to ensure that
gas flow to the pump is stopped when nitrogen is lost.
If loss of cooling water creates a significant risk, then the water flow must
be monitored externally by the process equipment.
If any corrosive, reactive, flammable, pyrophoric, oxidizing processes
can be sent to the pump, then an exhaust monitor should be used in the
secondary exhaust to ensure that gas flow to the pump is stopped when
secondary exhaust is lost.
In addition an interlock should be provided to ensure that gas flow to the
pump is stopped when nitrogen is lost.
If flammable materials are sent to the pump, the customer will need to
provide a hardware based LEL detection in the secondary exhaust (capable
of detecting at 25% of the LEL) that will stop chemical supply to the pump
when gas is detected at 25% of LEL for that flammable material.
