Danger zone This is an area in which only an authorised operator may work. The danger zone is the area inside the unit which is accessible only with the deliberate removal of protections or parts thereof.

  • Page 85: Electric Parts

    12 - RESIDUAL RISKS If there is a fire the temperature of the refrigerant could reach values that in-crease the pressure to beyond the safety valve with the consequent possible projection of the refrigerant itself or explosion of the circuit parts that remain isolated by the closure of the tap. Do not remain in the vicinity of the safety valve and never leave the refriger-ating system taps closed.
