Before every race, replace the battery in the electrical control. If the battery is dead, the system will not 
activate.  
Before every race, make sure that the needle on the bottle gauge is in the green zone. When the bottle gauge 
needle is outside the green zone, the extinguishing system is drained and must be charged. 
 

When the  control  box  lever  switch  is  in the  OFF  position, the  extinguishing  system is  disabled.  Check  that  the 
switch is in the ON position before using the vehicle. 
When the switch is set to ON the green LED 

④ 

on the cockpit panel will turn ON. 

 

 

Before connecting the control unit to the bottle, use a multimeter to check that: 

•

 

whit the lever switch on the control unit in the OFF position, when either of  the activation buttons is 
pressed the potential difference between the ends of the wires is about 7 - 8V  

•

 

with  the  lever  switch  on the  control  unit  in  the  ON  position,  when  either  of  the  activation  buttons  is 
pressed the potential difference between the ends of the wires is about 9V when neither of the activation 
buttons are pressed the potential difference between the ends of the wires is 0V.  

 
(PLEASE NOTE: after pushing either of the activation buttons, potential built up in the system needs to be dis-
charged before it gets back to zero. This can easily be achieved by touching the connectors). 
Before connecting the cable to the valve, switch the control unit to OFF mode. 
With the control unit switch in the OFF position, connect the bottle's explosive capsule.
