DANGER! Risk of fatal injury!
Failure to install safety devices of the electronic module and the
motor can cause electrical shock or contact with rotating parts,
potentially resulting in life-threatening injuries.
• Before commissioning as well as after maintenance work, all safety
devices such as module covers and fan cover that were removed
must be reinstalled.
• Keep a safe distance during commissioning.
• Never connect the pump without the electronic module.
Before commissioning, the pump and electronic module must be at
the ambient temperature.
• Prime and vent the unit correctly.
CAUTION! Risk of property damage!
Running dry will destroy the mechanical seal.
• Make sure that the pump does not run dry.
• To avoid cavitation noises and damage, a minimum inlet pressure
must be guaranteed at the suction port of the pump. This minimum
inlet pressure depends on the operation situation and the duty point
of the pump, and must be defined accordingly.
• The main parameters for defining the minimum inlet pressure are the
NPSH of the pump at its duty point and the vapour pressure of the
fluid.

• Vent the pumps by loosening the air vent valves (Fig. 43, Item 1). Any
dry running would destroy the mechanical seal of the pump. The dif-
ferential pressure sensor must not be vented (risk of destruction).
WARNING! Danger due to extremely hot or extremely cold pressur-
ised fluid!
Depending on the temperature of the fluid and the system pres-
sure, when the venting screw is opened completely, extremely hot
or extremely cold fluid in liquid or vapour form may escape or shoot
out at high pressure.
• Always exercise caution when opening the venting screw.
• Protect the module box from any water escaping when venting.
WARNING! Danger of burns or freezing to the pump when body
