12 Maintenance and Repair
This instrument does not contain any user-serviceable parts. The following notes are provided as a guide to general equipment
care.
WARNING!
Do not disassemble this unit unless advised by GF. Return the unit to an approved service agent or place of purchase for further
advice.
1. Ensure the unit is switched off and disconnected from the mains, then wipe the exterior of the instrument with a clean, damp
cloth or paper towel. The use of a solvent may damage the surface.
2. The instrument contains a rechargeable battery, dispose safely and in accordance with the local regulations in force in the coun-
try of operation.
3. Ensure all cables and connectors are kept clean and free from grease or contaminants. Connectors may be cleaned with a gen-
eral purpose cleaner if necessary.
4. Avoid the use of excessive grease/ultrasonic couplant on the sensors as this may impair the performance of the equipment. Ex-
cessive grease/couplant can be removed from the sensors and guide rails using an absorbent paper towel and a general purpose
solvent cleaner.
5. We recommend that the ultrasonic couplant is replaced on the sensors every 6 months, especially on pipes where the applica-
tion is too hot to touch. If the signal level drops below 30% this is also an indication that the sensors need re-greasing.
6. Regularly check all cables/parts for damage. Replacement parts are available from GF.
7. Ensure the person who services your instrument is qualified to do so. If in doubt, return the instrument to GF with a detailed
report on the nature of any problem.
8. Ensure that suitable precautions are taken when using any materials to clean the instrument/sensors.
9. The instrument and sensors should be calibrated at least once every 12 months. Contact GF or your local GF partner for details.
10. When returning product to GF make sure it is clean and please notify GF if the instrument has been in contact with any hazard-
ous substances.
11. If the instrument was supplied with dust or dirt caps make sure they are re-fitted when the instrument is not in use.
