Copeland 998-0574-03 Fan Motor Mounting Kit

The Copeland 998-0574-03 Fan Motor Mounting Kit is the OEM bracket assembly Copeland specifies for mounting an auxiliary vertical head-cooling fan on 4D and 4R model semi-hermetic Copelametic and Discus compressors, including the 4D1 and 4R1 body variants. Air-cooled Discus and Copelametic compressors depend on direct fan discharge across the compressor head for proper cooling — Copeland's own Application Engineering Bulletin AE4-1135 documents that compressors mounted outside a condenser's fan discharge stream, or running at low evaporating temperatures with elevated return-gas temperatures, require this auxiliary vertical fan to avoid overheating and premature failure. The kit includes the mounting bracket, studs, spacers, connectors, and conduit needed to install the fan assembly on top of the compressor head; it does not include the fan motor itself, which ships separately as one of Copeland's 998-0550 series assemblies (998-0550-00 for 230V, 998-0550-01 for 440/380V, or 998-0550-02 for 115V single-phase power).

Per the same bulletin, adding this vertical fan assembly increases the compressor's overall height by roughly 9.5 inches on 4D/4R bodies — a clearance detail worth checking before ordering if the compressor sits in a tight condensing-unit enclosure. This mounting kit is a direct OEM fit specific to the 4D and 4R body family; it is not interchangeable with the mounting kits Copeland specifies for other body sizes, such as 998-0574-04 (6D-6R) or 998-0574-11 (2D).

Key Benefits

• Exact 4D/4R Fit: Machined and specified by Copeland for 4D1-4R1 model compressors — not a universal mounting solution.
• Complete Hardware Set: Bracket, studs, spacers, connectors, and conduit in one kit — no separate hardware sourcing needed.
• Solves a Real Cooling Problem: Provides the direct fan-discharge airflow Copeland's AE4-1135 bulletin requires for compressors that can't rely on condenser fan discharge alone.
• OEM Manufacturing: Built to Copeland's original tolerances so the fan sits correctly and airflow reaches the head as engineered.

Common Questions

• What compressor does this fit? Copeland 4D and 4R model semi-hermetic compressors, including 4D1-4R1 variants.
• Does this kit include the fan motor? No — this is the mounting hardware only. The fan motor and blade assembly ship separately as a 998-0550 series part matched to your voltage.
• Will this fan mount add height to my compressor? Yes — Copeland's bulletin lists roughly 9.5 inches of added clearance on 4D/4R bodies once the fan is installed.
