Safety instructions
When the pump is switched off, internal parts (monitoring, frequency
converter) contain capacitors charged with over 60 VDC and remain
energized.
Electrical shock may result in severe injury.
Wait 1 minute after switching off before opening the pump.
Lock out / tag out water and N
2
supplies.
The end user needs to provide a dedicated source of water and nitrogen
equipped with manual valves that can be locked out within 10 feet of the
tool.
Other located hazardous energies.
Nitrogen purge and water cooling circuit are pressurized hazardous
energies. Release pressure before servicing:
for the N
2
purge, disconnect the gas line quick connector and turn off the
pressure regulator by turning the knob counter-clockwise;
for the water cooling circuit, disconnect the input connector and leave the
output connected. Wait 1 minute before disconnecting the output.
Operating conditions may generate temperatures justifying particular
attention on the part of the user (external surfaces > 70°C on exhaust
connections).
Contact may cause burns.
Wait 30 min before servicing and always use gloves. The protective
gloves should be used in accordance to the protective gloves supplier’s
instructions.
General (continued)
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 Lower Explosive Limit detection in the secondary
exhaust (capable of detecting at 25% of the Lower Explosive Limit) that will
stop chemical supply to the pump when gas is detected at 25% of Lower
Explosive Limit for that flammable material.
To connect this detection, the customer can use the EMO connector, pins 2
and 3
