1. Voltage too low will not complete the stroke of alternating current (AC) and the solenoid will
burn out the coil.

valves will be unable to complete their stroke and burn out. Make certain the electrical
signal is interlocked so that this condition cannot exist.
3. Incorrect voltage or frequency will prevent operation or burn out coil.
4. Foreign matter in valve.
5. Oil too hot.
PUMP
1. Excessive noise caused by vacuum leak in suction line.
2. Misalignment of drive mechanism will cause high noise level in operation.
