Ebara Self Priming Jet Pumps JEU
Preparation for Use (continued)
Electrical Connection (continued)
• For connection to the power mains, use a cable complying with IEC
standards with a suitable section (bearing in mind the installed
power, as on page 4) and a suitable length; remember also the
mains voltage and polarity (page 4).
• The power cable must be connected to the terminals as illustrated in
the wiring diagram.
• The mains must have an efficient ground system complying with the
electrical standards in force in the users country; the installer is
responsible for checking this.
Single Phase Version
The pump must preferably be fed by means of an electric panel with a switch
and fuses. The electric panel must be prepared by a trained electrician.
Three Phase Version
The three phase version does not have an internal motor protector, therefore
the protection against overload must be supplied by the user. The pump must
be fed by means of an electric panel with switch, fuses and a thermal switch set
at the current absorbed by the pump. The electric panel must be prepared by a
trained electrician.
Filling the Pump
WARNING
– THIS OPERATION MUST BE PERFORMED WITH THE ELECTRIC
BASE OF THE MOTOR COMPLETELY CLOSED.
a)Unscrew the hexagonal cap located on the top of the pump body, in
front of the delivery union.
b)Using a funnel, fill the pump body with water until it overflows.
c) Screw the hexagonal cap back on until it is firmly locked, to prevent
air infiltration.
Adjusting and Registering
Check that there are no leaks in the system.
Ensure that the pump does not vibrate abnormally during operation, is not too
noisy, and does not have large variations in pressure and electric absorption. If
any of these are found, refer to page 11.
