DANGER
Excessive surface temperature
Explosion hazard!
Risk of burns!
▷ Observe the permissible temperature classes. (ðSection2.9.2,Page11)
CAUTION
Lack of heating medium
Damage to the pump!
▷ Provide sufficient quantities of a suitable heating medium.
CAUTION
Time for warming up the pump too short
Damage to the pump!
▷ Check that the pump is sufficiently warmed up throughout.
CAUTION
Impermissibly high temperature of the heating medium
Fluid or heating medium could escape!
▷ Observe the application limits of the heating media.
