If your pump is not working on both speeds (if dual speed pump) or if your accessories (i.e. blower) are not working:
∙ Replace the problematic fuse linked to your pump or your accessory (i.e. blower) with a new one.
∙ Verify the fuse replacement rectifies the problem.

Pump 1 fuse (F1)
Pump 2 fuse (F2)
If replacing the fuse has no effect, or if the pump only works on one speed, measure the tension of the corresponding
connector:
∙ Activate your pump on the problematic speed or the accessory (i.e. blower).
∙ Referring to your control systems connexion diagram, measure the tension between the pump or blower output and its return.
You should measure:
120 V for a 120 V pump or accessory
240 V for a 240 V pump or accessory
If the tension is compliant, verify the cables and connectors and replace if necessary. If need be, replace the pump or the
accessory.
If the tension is not compliant, replace the control system.

Measuring tension on in.yj:
Example: your pump 1 high speed (240V) is not working.
Referring to the connexion diagram you may see that the pump 1 output is connected on K7-P (Pump 1 high speed) and the
return should be on one of the TAB of line 2 (P14, P15, P16 or P37) for a 240V pump and on one of the Neutral TAB (P18, P19,
P20, P21 or P35) for a 120V pump.
Measure the tension between the K7-P and your return (Line 2 or Neutral),
you should measure:
120 V for a 120 V pump or accessory
240 V for a 240 V pump or accessory
Measuring tension on in.ye and in.yt:
Example: your pump 1 high speed (240V) is not working.
Referring to the connexion diagram you may see that the pump 1 output is linked to the A3 connector (pump 1 output).
Measure the tension between pin 1 (pump 1 high speed output) and pin 3 (return),
you should measure:
120 V for a 120 V pump or accessory
240 V for a 240 V pump or accessory
