Application and Installation Notes
The BlueCool S13 115V is designed for medium staterooms or small salons up to 550 cubic feet. Installation planning should verify the 115V supply, 25 A breaker, and minimum 3.5 kW generator guidance.

Who This Unit Is Not Ideal For
This system is not appropriate for boats with 230V-only power or spaces requiring substantially more than 13,000 BTU/h. It may also be excessive for very small cabins. Final sizing should account for insulation, glazing, solar exposure, ventilation, and local climate.

Webasto S13 115V Marine AC FAQ
What are the electrical requirements for S13?
Webasto S13 operates safely on a 115V power supply. This single-phase domestic network installation draws minimal running current, allowing long-distance coastal cruisers to distribute climate loads smoothly over standard American shore lines or small diesel generator panels without throwing primary distribution breakers during high-load summer periods.
What airflow volume does this system deliver?
Webasto S13 generates an airflow volume of 324 CFM. The integrated rotatable high-velocity centrifugal blower fan operates dynamically to flush hot humidity profiles from cramped living spaces while keeping system resonance decibels extremely low against lightweight composite structural hull partitions and marine plywood cabin walls.
Which vessels fit the Webasto S13?
Webasto S13 is designed for mid-sized cabins and crew quarters. It provides optimal cooling coverage for sailboats and motor yachts ranging from thirty to thirty-eight feet, delivering efficient climate regulation underneath bunk spaces or within designated cockpit lockers without taking up crucial living space.
