INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
1. Installation
Install the pump to the base and ensure that no load is transferred
to the pump from the pipework. Use suitable spacers between the
pump and the base when necessary. Follow the instructions of the
manufacturer of motor and make sure that cooling air is provided
for the motor.
Adjust pipework on the suction and pressure side so that the anges
t easily together. Make sure that xing of bolts will not cause any
load to the pump body. Connect the cable to the control panel as
shown in the electrical diagram. Check direction of rotation to be
clockwice by shortly starting the pump.
! NOTE: Do not run the pump dry for more than just a few seconds, because longer dry running will damage the
