4. Maintenance

The SF -LeakPointer is designed to require a minimal amount of field maintenance. Periodic
6
replacement of the unit's sensor and batteries are the only maintenance needs:

LOW BATTERY CONDITION: When the batteries reach approximately 10% of capacity, the
rightmost LED of the tachometer indicator (above the LO BAT symbol) will energize. The other
seven LEDs will continue to function as indicators of the leak's relative size.

CHANGING THE CCD SENSOR: The CCD sensor assembly consists of metal and plastic
components. Do not attempt to remove one component from the other. Do not use solvents or
cleaning solutions for cleaning the sensor. It should be replaced when air vents become clogged.
Eventually, the sensor will need to be replaced. This condition is usually indicated by abnormal or
erratic performance. With the unit OFF, the old sensor can be removed by screwing off and the
new one can be screwed on afterwards. DILO recommends that you always have a spare sensor
available for replacement in the field.
Only authorized personnel should carry out maintenance works in accordance with
maintenance instructions and regulations for the prevention of accidents.
Warning
In case of non compliance this could result in considerable damage to the equipment.
