•
The instrument being dropped or any other comparable mechanical stress
may result in breakage of the pipe sections 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, return the instrument to 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
equipotential 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.
•
Use with A2L refrigerants
Testo measuring instruments (as of July 2020) can be used in compliance
with the prescribed laws, standards, directives and safety regulations for
refrigeration systems and refrigerants as well as regulations of the
manufacturers of refrigerants of safety group A2L as per ISO 817.
Regional standardization and interpretation must always be observed.
For example, DIN EN 378-Part 1-4 applies to the scope of the EN standards.
During maintenance work, the employer must ensure that a hazardous
explosive atmosphere is prevented (see also TRBS1112, TRBS2152 VDMA
24020-3).
A hazardous and potentially explosive atmosphere must be anticipated
during maintenance and repair work on refrigeration systems with flammable
refrigerants (e.g. those in category A2L and A3).
Maintenance, repairs, removal of refrigerants and commissioning of systems
may only be carried out by qualified personnel.
