WARNING
Dropping this instrument or any other comparable mechanical
shock can damage the refrigerant pipes and hoses. The valve
actuators may also suffer damage, which in turn could result in
further damage inside the instrument and may not be detectable
from outside.
> For your own safety you should return the manifold to the
Testo Service Department for technical inspection.
> You should therefore always replace the refrigerant hoses with
new ones after an accidental drop has occurred or after any
visible wear and tear.
