Refrigerating circuit safety valves
Each system comes with safety valves that are installed on each circuit, both on the evaporator and on the condenser.
The purpose of the valves is to discharge the refrigerant inside the refrigerating circuit in the event of any malfunction.
This unit is designed for installation outdoors. However, check that there is sufficient air circulation around the machine.
If the machine is installed in closed or partly covered areas, possible damage from inhalation of refrigerant gases must
be avoided. Avoid releasing the refrigerant in the environment.
The safety valves must be connected externally. The installer is responsible for connecting the safety valves to the
discharge piping and for establishing their size.
