Figure 12 - Evaporator Pressure Drop - Daikin EWYD-BZ Series Installation, Maintenance & Operation Manual

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 release the refrigerant inside the refrigerating circuit in the event of certain malfunctions.
This unit is designed for installation outdoors. However, check that there is sufficient air circulation through 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 into the atmosphere.
The safety valves must be so connected to discharge outdoors. The installer is responsible for connecting the safety
valves to the discharge piping and for establishing their size.
