terfering signals might occur.
Non-sinus shaped supply voltage from a varia-
ble frequency drive might result in elevated
motor temperatures.

7 Operation

WARNING
Risk of injury by uncontrolled start-up of the
pump or absence of emergency shutt of
switch!
– Unwanted pump start-up or missing shut off
switches can cause severe injury through
ejected parts from the pump discharge or
from cutting or pulling body parts into the
pump suction.
– Reassure that pump is disconnected from
power source and cannot be switched on.
– It is the responsibility of the machine opera-
tor to decide whether or not an additional
emergency switch must be installed.
Liquid level
According to the drawing 3, the maximum liquid
level must stay about 30 mm below the mounting
flange.
The pump begins to prime once the liquid level
(coolants) reaches the agitator.
The pump suction is at the bottom of the immersed
pump body.
The pump draws the fluid level down to the level of
the agitator.
The bottom of the agitator must be located 100 mm
above the tank bottom (see drawing 3) in order to
prevent unwanted objects, such as broken tools or
indexing plates from entering the pump suction.
This distance is critical and must be maintained at
all times.
