CHAPTER 4

ELECTRICAL CONNECTION

WARNING
Ensure tension and frequency of electropump (read plate) and power supply are same.
DANGER - ELECTRIC SHOCK RISK
Installer must make sure that electric current network has ground wire conforming to current laws.
DANGER - ELECTRIC SHOCK RISK
Make sure that electric current network is provided with a high-sensitivity circuit breaker
∆=30 mA (DIN VDE 0100T739).
The single phase motors are protected from overloads by a thermal device installed in the winding. The protection for the three phase
motor must be installed by the user. The following must be used as a conductor for the connection:
Outdoor → cable H07RN-F
•
• In inside areas → cable H05RN-F or
H07RN-F
CHAPTER 5
STARTING THE UNIT (SEE FIG. 5)
WARNING
Use the electropump for the applications listed on the nameplate. Before using the pump, read Application chapter for a
proper use.
WARNING
Do not operate the pump dry, since lack of water could cause it to overheat. In this case, the water inside the system gets
very hot, so there is a risk of scalding. Take off the plug and let the system cool down.
WARNING
Do not run the electropump with a completely closed delivery.
Before starting the electropump fill the suction pipe and the electropump body with water by using the filling cap, making sure
that there are no leaks, close the cap and start the electropump (4). Check that it rotates counter-clockwise when looking at the
electropump from the side of the motor fan. On the three phase electropumps it is possible to invert the rotation by changing the order
of two phases. If the electropump is not used for long periods of time repeat the filling operations before starting it up.
CHAPTER 6
MAINTENANCE AND TROUBLE SHOOTING
DANGER - ELECTRIC SHOCK RISK
Before doing any operation, make sure machine is disconnected from electric power supply.
• Under normal conditions
MULTINOX VE+ electropumps do not
need any type of maintenance
• In order to avoid possible failures,
it is advisable to periodically check
the pressure supplied and current
absorption
• For connecting single phase motors
see Fig. 1
• For connecting three phase motors
see Fig. 2
• A decrease in pressure is a symptom
of wear. An increase in current
absorption is a sign of abnormal
mechanical friction in the pump
and/or motor
• If the electropump is not going to be
used for long periods of time
(e.g. an entire season) it should be
• For connecting double voltage single
phase motors see Fig. 3
emptied completely, rinsed with clean
water and put in a dry place
• If the pump is used for applications
with drinking water for human
consumption and it is not used for a
long period, repeat the procedures
listed in Installation chapter.
