Specifications - TESTO 523 Instruction Manual

Warning!
Danger of injury exists if highly pressurized hot, cold and/or toxic
refrigerants escape. For this reason, always wear protective glasses
and protective gloves when carrying out measurements and other
work on the refrigeration system.
If the measuring instrument falls down or is exposed to any other
comparable mechanical strain, the end connections of the refrigerant
hoses can break off. The valve knobs can also be damaged, which
can lead to further damage in the interior of the instrument, which is
not visible externally. For this reason, replace the refrigerant hoses
after any fall or comparable mechanical strain with new, undamaged
refrigerant hoses. For your own safety, send the instrument to Testo
customer service for technical testing.
Protecting the environment
Refrigerant gases can damage the environment. Observe the relevant
environmental protection regulations.
Dispose of faulty rechargeable batteries/empty batteries at the proper
collection points.
Send the product back to Testo at the end of its life. We will ensure that it is
disposed of in an environmentally friendly manner.
