4 Product-specific information
• The measuring instrument being dropped or any other comparable
mechanical stress may cause breakage of the pipe pieces in the refrigerant
hoses. The valve positioners may also suffer damage, causing further
damage inside the measuring instrument that is not necessarily visible
externally. Therefore, always replace the refrigerant hoses with new ones
after the measuring instrument is dropped or after any comparable
mechanical stress. For your own safety, you should return the measuring
instrument to the Testo Customer Service for technical inspection.
• Electrostatic charging may destroy the instrument. Integrate all the
components (system, manifold's valve block, refrigerant bottle, etc.) into the
potential bonding (earthing). Please see the safety instructions for the
system and the refrigerant used.
• Refrigerant gases can harm the environment. Please note the applicable
environmental regulations.
