Before star ng the pump for the first  me , open the central by‐pass valve fully to avoid any over pressure in 
the cell housing.  Once the pump is running, open the inlet and outlet valves slowly un l they are fully open. 
You can then par ally close the central valve in order to send the flow through the cell un l you have a rapid 
an uniform flow. The water must flow at a sufficient speed thought the cell. If the flow is too low scale could 
build on the electrodes. If the installa on is not provided with a dedicated  pump for the chlorinator, adjust 
the flow rate by ac ng on the by‐pass centre valve. 
 
When the cell is being filled the air trapped in the cell housing can prevent the water to flow.  You can tem‐
porarily loose the flow switch in order to evacuate the air inside. Once the cell housing is completely filled, 
don’t forget to re ghten the flow switch. Verify that the arrow marking on the flow switch corresponds to 
the water flow a er re ghtening.

 

 
 

6. ELECTRICAL CONNECTIONS 

 
Power supply cable 
 

The chlorinator must be powered to 230 VAC. Connect the three‐wire power supply cable (marked “230 VAC 
power supply”) to a permanent 230 VAC mains power supply with protec ve earth. The voltage on this cable 
must  be  keep  constant  as  long  as  the  chlorinator  is  in  use.   

DO  NOT  INTERRUPT 

the  power  on  this  cable 

along  the pump working cycles or by means of any other control device. In order to control the chlorinator 
produc on cycles use the 

External Control Cable

. Disconnect the power supply only when you are not going 

to use the chlorinator or in case of fault. 

  

The chlorinator must impera vely  be  connected  to a protec ve earth  through its  power supply cable 
and protected by a 30 mA residual circuit breaker.  

 
  

External Control Cable 
 

The two‐wire cable marked  “

EXTERNAL CONTROL 230VAC

” is used to start and stop the chlorine produc on 

synchronically with the pump working cycles or by means of a control device. When the voltage applied be‐
tween the two wires is 230VAC the chlorinator will produce chlorine. When the voltage between the wires is 
0 VAC the chlorinator will halt the chlorine produc on and enter a pause mode. Therefore, the voltage ap‐
plied to the control cable must be driven by the same means, signal or device that powers or controls the 
pump. 

Make sure that the voltage applied to the External Control Cable is 230VAC ONLY when the pump is 
running and the water flows freely through the cells and to the pool. 

 

6. OPERATION 

 

The SMC50‐75 cell is controlled by means of  a keyboard and a display. In a electroly c cell, chlorine genera‐

on is propor onal to the electrical current flowing through it .The SMC50‐75 will try to maintain a constant 

electrical current in the cell according to the chlorine produc on rate (0—100%) set by the user.  The values  
of current and voltage in the cell are constantly displayed in the main screen. In normal condi ons and at 
100% produc on rate the current value (I1) must be as follows: 
SMC50:   7.0 A   to  8.5 A   

 

 

SMC75:     11.0 A  to 13.5 A
