Electrical Connections 

AMICO Circulator doesn't need an external motor protection.  
Check if voltage and frequency are consistent with values in the pump 
plate. 
The circulator is working when the control-panel-light turns on. 
If the power cord is damaged, it must be replaced. 
Protection fuse: 1A. 

 

 

Electrical Connection

 

Electric Cable  
Max diameter 10mm 
Min diameter 5mm

 

Insert  the  cables 
in  the  correct  or-
der 

Cable is 

0,75mm

 

WARNING! 

AMICO  Circulator must be connected to the ground wire. 
The pump must be connected to an external power switch. 
The min. clearance between the electrodes should be 3mm. 

14 

The pump is equipped with the function S3, self purging function. After 
the start of this setting, the air in the pipes (cause of noise and malfunc-
tions) wears off after a few minutes. 
 

10. Relations between pump setting and performance 

Such reports shall be expressed in the diagram below. 

Expulsion of air 

It means running 

for 5 minutes 

Do not start the pump without pumping liquid. 
Do not start the pump before expelling the air in the pipes.
