CAUTION
Increased wear due to dry running
Damage to the pump set!
▷ Never operate the pump set without liquid fill.
▷ Never close the shut-off element in the suction line and/or supply line during
pump operation.
1. Vent the pump and suction line and prime both with the fluid to be handled.
Connection 6D can be used for venting (see drawing of auxiliary connections).
For vertical installation with the motor on top use connection 5B (if any) for
venting (see drawing of auxiliary connections).
2. Fully open the shut-off element in the suction line.
3. Fully open all auxiliary feed lines (barrier fluid, flushing liquid, etc.), if any.
4. Open the shut-off valve (3), if any, in the vacuum balance line (2) and close the
vacuum-tight shut-off valve (6), if any. (ðSection5.3.3,Page24)
WARNING
Hot water escaping under pressure when the vent plug is opened
Risk of electric shock!
Risk of scalding!
▷ Protect the electric components against escaping fluid.
▷ Wear protective clothing (e.g. gloves).
NOTE
For design-inherent reasons some unfilled volume in the hydraulic system cannot be
excluded after the pump has been primed for commissioning/start-up. However,
once the motor is started up the pumping effect will immediately fill this volume
with the fluid handled.
6.1.5 Start-up
DANGER
Non-compliance with the permissible pressure and temperature limits if the pump
is operated with the suction and/or discharge line closed.
Explosion hazard!
Hot or toxic fluids escaping!
▷ Never operate the pump with the shut-off elements in the suction line and/or
discharge line closed.
▷ Only start up the pump set with the discharge-side shut-off element slightly or
fully open.
DANGER
Excessive temperatures due to dry running or excessive gas content in the fluid
handled
Explosion hazard!
Damage to the pump set!
▷ Never operate the pump set without liquid fill.
▷ Prime the pump as per operating instructions.
