the Trane CNT04959 is engineered for a direct-fit installation into TCD rooftop units and other light commercial applications

it requires a specific run capacitor (typically rated for these 1 HP specs) to start and run efficiently

Optimized for seamless integration with Nordyne

Does it require a vent protector for outdoor use

it maintains performance standards across a broad ambient temperature range from -20 to 150°F

Sporlan 901229P Regulator 321894-708 the Trane CNT04959 is engineeredThe Sporlan 901229P, specifically the ORIT 10 series, is a direct acting evaporator pressure regulator (EPR) engineered to provide precise control over evaporator temperatures by maintaining a minimum set pressure. Designed with a robust brass body and 1 1 8" ODF extended copper connections, this commercial refrigeration EPR prevents the evaporator pressure from dropping below the designated 30 to 100 PSI range, effectively protecting against coil
