WARNING
There is a risk of burns or freezing upon coming into contact with the
pump/system.
Depending on the pump and system operating conditions (fluid temperature), the
entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• Allow the system and pump to cool to room temperature!
• Always wear protective clothing, protective gloves and protective goggles when
working.
DANGER
Danger of personal injury and property damage due to extremely hot or
extremely cold pressurised fluid!
Depending on the temperature of the fluid, when the venting device is opened com-
pletely,
extremely hot
or
extremely cold
fluid may escape in liquid or vapour form.
Fluid may shoot out at high pressure depending on the system pressure.
• Always exercise caution when opening the venting device.
Fill and vent the system correctly.
1.
To do this, loosen the air vent valves and vent the pump.
2.
After venting the pump, tighten the air vent valves again so that no more water
can escape.
NOTICE
• Always keep to the minimum pressure!

Check direction of rotation
ƒ
To avoid cavitation noises and damage, a minimum inlet pressure must be guaran-
teed at the suction port of the pump. The minimum inlet pressure depends on the
operating situation and the pump’s duty point. Accordingly, the minimum pressure
must be determined.
ƒ
The main parameters for defining the minimum inlet pressure are the NPSH value
of the pump at its duty point and the vapour pressure of the fluid. The NPSH value
can be found in the technical documentation of the respective pump type.
1.
By briefly switching on, check whether the direction of rotation agrees with the ar-
row on the fan cover. If the direction of rotation is incorrect, proceed as follows:
ƒ
For direct starting: Swap two phases on the motor terminal board (e.g. L1 for L2).
ƒ
For Y-Δ starting:
Swap the thread start and thread end of two windings on the motor terminal board
(e.g. V1 for V2 and W1 for W2).
9.3
Activation
ƒ
The unit may only be switched on when the shut-off device on the discharge side
is closed! Only after full speed has been reached may the shut-off device be slowly
opened and be adjusted to the duty point.
The unit must run smoothly and free of vibration.
The mechanical seal ensures that a seal will not leak and requires no special setting.
Should there be a small leakage at the beginning, it will stop when the initial inlet phase
of the gasket is over.
