What is the farthest I can run the exhaust/cooling ducts? Can I block one duct on CP units?
Varies, depends on models (See Specifications: Click the following link to view the specifications- http://www.movincool.com/downloads/overview_specs.pdf). Length specified is total length in and out of unit. For condenser plenum, 10’ inlet and 10’ outlet = 20 total feet. Each 90 deg bend = approx 8’-10’ of duct. Blocking one duct is not recommended. Too much static pressure can build up and the unit will shut down.
