within 6 feet of the unit and at least two other discharges need to be at
least the 4” round supply vents. More is better! Unit Dimensions:
L-19.75" W-13" H-13.75". Running Amperage:
Cool = 9.4 amps, Electric Heat = 17.5 amps, Reverse Cycle = 11.4 amps (Add
approximately one amp for the standard seawater pumps. Startup amperage is calculated by running amperage multiplied by 1.8).
