The Manitowoc K00438 is a precision-engineered top air discharge conversion kit specifically designed for 22-inch ice machine models, including the S-322, S-522, and Indigo® series. This kit is a critical accessory for installations where lateral space is at a premium. By redirecting the hot condenser exhaust from the side of the machine to the top, the K00438 prevents heat from being trapped in tight cabinetry or alcoves. This upward airflow design eliminates "heat recirculation," ensuring the machine pulls in cool ambient air from the front, which maintains maximum ice production levels and significantly extends the operational life of the compressor.

  • Model Number: K00438 (Genuine Manitowoc Accessory)
  • Compatibility: Designed for 22" wide S-Series (S-322, S-522) and Indigo® Series heads
  • Function: Diverts hot exhaust air from the side to the top of the unit
  • Space Optimization: Allows for "zero-clearance" side installations in restricted spaces
  • Performance: Maintains factory-rated ice harvest cycles by preventing high head pressure
  • Construction: High-grade commercial materials designed to match the ice machine's finish
  • Kit Includes: Air plenum, top panel assembly, and necessary mounting hardware
Technician's Note: In compact 22-inch installations, heat buildup is the primary cause of service calls. If your machine is tucked between a wall and a reach-in cooler, the K00438 is essential. Without it, the unit will "short-cycle" as the intake air temperature rises, leading to thin ice or no ice at all. When installing, verify that there is at least 12 inches of open space above the machine for the redirected air to dissipate. Also, ensure the condenser fins are cleaned before installing the shroud to ensure the fan motor isn't fighting against existing dust buildup.
