✓ The valve actuators are closed.
1. Connect the refrigerant hoses for low-pressure side (blue) and
high-pressure side (red) to the measuring instrument.
2. Connect the refrigerant hoses to the system.
WARNING
The measuring instrument dropping down or any other comparable
mechanical load can cause breakage of the pipe pieces in the
refrigerant hoses. The valve actuators may also suffer damage,
which in turn could result in further damage inside the measuring
instrument, which may not be detectable from outside.
> For your own safety you should return the measuring
instrument to the Testo Service for technical inspection.
> You should therefore always replace the refrigerant hoses with
new ones after the measuring instrument has dropped down or
after any comparable mechanical loading.
