Rights of alteration
The manufacturer reserves the right to make technical alterations to systems or components. This
operating and maintenance manual refers to the product indicated on the title page.
“S2” operat-
ing mode
(short-term
operation)
The period of service at the rated load is short in comparison to the subse-
quent pause. The maximum operating period is indicated in minutes, for
example, S2-15. The operating equipment can operate during this time
uninterruptedly at the rated load without exceeding the maximum permissi-
ble temperature. The pauses must continue until the machine temperature
no longer exceeds that of the coolant by more than 2K .
“Siphoning
operation”
Siphoning operation is similar to dry running. The product operates at full
speed, but only small amounts of liquid are pumped.
Siphoning operation is
only possible with certain types; see the “Product description” chapter.
Dry-run pro-
tection
The dry-run protection is designed to automatically shut down the product
if the water level falls below the minimum water coverage value of the
product. This is made possible by installing a float switch.
Level control
The level control is designed to switch the product on or off depending on
the filling level. This is made possible by installing a float switch.
