Operation

 The pumps should only be used under normal operating pa-
rameters / conditions which are described in section 4 – tech-

 Ensure that the pumps are being used correctly (see section
2.1).
 Improper use of the pump must be avoided (see section 2.2).
 Observe the safety notes (see chapter 3).
 The pumps are components which have to be integrated into a

Danger of burning
The motor heats up
 Don't touch the motor
CAUTION
 Don't let the motor come in contact with flamma-
ble materials
Excessive pressures and the dangers thus caused can be
prevented by using a bypass system with a pressure relief
valve between the pressure and suction side of the pump. For
further information please contact a KNF specialist (Telephone
number: see front page).
 If the pump stops running release the pressure in the system to
that atmospheric conditions are created.
For pumps with a thermal switch:
Physical injury and damage to the pump due to
automatic start.
If in the case of excessive temperatures the thermal
switch will stop the motor. Once cooled down the
WARNING
motor will automatically start operation again.
 Ensure that no dangerous situation can thereby
arise.
Switching the pump on and off
The motor speed and thus the flow rate can be adjusted / con-
