3.5 Adjusting the valve solenoid
The fixing screws of valve solenoid are fastened somewhere in the middle of the fixing slots. The
lowest position is not probably the correct one for the solenoid because there is a risk that in some
cases the valve might leak back to the canister during dispensing.
Tools required:
• Cross head screwdriver
Procedure:
1. Loose the solenoid fixing screws (marked with arrow to figure 35) so that the solenoid drops
to the lowest position.
2. Place a small tool under the plunger and push the plunger upwards until the draft bar touches
the outlet of the pump, see figure 35. Also the solenoid coil moves upwards.
3. Tighten the solenoid to this location with screws.
