Protective Weather Cap
For outdoor vertical installations of the Inline 400, the protective weather cap should be used for maximum protection of the unit. It is not recommended that the Inline 400 be installed horizontally for outdoor applications where the unit would be directly subjected to inclement weather. Horizontal installations will continue to be approved for INDOOR use only. The installation of the enclosed protective weather cap is simple. After the Inline 400 unit has been installed, attach the protective cover over the top of the unit using the affixed Velcro button. The clear protective cover allows for viewing of the unit’s operation lights, but does not allow access to the user interface button. In order to access the user interface button, the cover must be removed. After the required button activation is completed, the protective weather cover must be reassembled to the unit. Please reference the owner’s manual for complete installation instructions.

The New Outdoor Rated Inline 400 comes with a standard 1.25-inch male NPT thread connection fittings. These new connections allow for hassle free installations that are quick, strong, and leak free.
