Application and Installation Notes
The BlueCool S13 230V is a global refit configuration for living spaces up to 550 cubic feet. Confirm the vessel’s 230V supply, 15 A circuit breaker, and minimum generator capacity of 3.0 kW before installation. The 12.2 x 15.7 x 13.4-inch unit requires suitable clearance, five-inch ducting, half-inch condensate drainage, five-eighth-inch seawater connections, and a 250 GPH water circuit.
Who This Unit Is Not Ideal For
This model is not suitable for 115V-only vessels or spaces that require more than the stated 13,000 BTU/h capacity. It may also be unnecessary for buyers who only need cooling. Final sizing should reflect cabin volume, insulation, windows, climate, and actual heat load.

How much does Webasto S13 weigh?
Webasto S13 weighs exactly 57.3 lbs net weight. This high-efficiency premium self-contained marine air conditioner delivers 13,000 BTU of cooling and heating output, allowing yacht owners to optimize mid-sized cabin environmental parameters efficiently without loading excessive equipment mass down on structural composite hull frames.
What duct size does this unit need?
Webasto S13 requires a 5 inch duct ring size. This dedicated diameter specification allows your extra-quiet 360-degree rotatable centrifugal blower assembly to distribute large volume air smoothly, eliminating static pressure restrictions inside narrow bulkheads and maintaining uniform thermal reduction throughout boat living quarters.
Where should you install Webasto S13?
Webasto S13 is perfect for mid-sized master staterooms and aft cabins. Marine technicians typically install this 13,000 BTU unit under settees or inside deep cockpit lockers on motor yachts up to thirty-eight feet, where its high-efficiency hermetic rotary compressor keeps mechanical vibration sound signatures minimized.
