▷ Completely prime the pump set with the fluid to be handled to reliably prevent
the formation of a potentially explosive atmosphere.

casing.
▷ Never allow the fluid level to drop below the specified minimum (R3).
▷ For continuous duty (S1) operate the pump set in fully submerged condition.
For IE3 motors observe the minimum fluid levels R3 or R4.
▷ For intermittent periodic operation (S3, 25 %, 10 min), observe the minimum
fluid levels R1 or R2.
Before commissioning/starting up the pump set, make sure that the following
conditions are met:
▪ The pump set has been properly connected to the power supply and is equipped
with all protection devices.
▪ The pump has been filled with the fluid to be handled. The pump has been
vented.
▪ The direction of rotation has been checked.
▪ The lubricants have been checked.
▪ After prolonged shutdown of the pump (set), the activities required for returning
the equipment to service have been carried out. (ð Section 6.4, Page 99)
