avantages
Protects the inside of the electrical box from dusts and sand.
In general this option is recommended for installations in
polluted environments
Improves aesthetics, protection against intrusion to the unit
interior, coil and piping protection against impacts.
Improves aesthetics, coil and piping protection against
impacts.
