CellarPro Outdoor Wall Cap for 6-Inch Ducting (P/N 30373). The outdoor wall cap provides rain protection, features a built-in bird screen, and is designed to cap 6″ ducting. This wall cap is compatible with the following CellarPro models and airflows:

• 1800QTL / QT / XT / XTS cooling unit hot-side exhaust or return air
• 1800H hot-side exhaust or return air
• 2000VS hot-side exhaust or return air

Restricted space, long duct runs, multiple duct bends, high temperature conditions and/or other airflow restrictions may cause the cap to be too restrictive for the cooling unit.

Please note: If the cap will be used for the return airflow:

• It should not be placed in direct sun, because the temperature of the return air may become too warm
• If outdoor temperatures drop below 40F, make sure that you add compressor heater #1727 to your order
• If outdoor temperatures drop below 20F, make sure that you add fan cycling switch #6972 to your order

Please note: Our units were not designed for, and our warranty does not cover damage from, marine exposure (within 5 miles of the ocean). In these environments, you will need an applied coating, such as Insitu®, to protect against corrosion that is common in coastal regions.
