The Manitowoc RC53 is a professional-grade 50-foot refrigerant line set specifically engineered for high-capacity QuietQube® ice machine systems. This line set provides the critical connection between your indoor ice machine head and the outdoor CVDF1400 or CVDF1800 remote condensing units. Designed to support Manitowoc’s "Cool Vapor Defrost" (CVD) technology, the RC53 ensures efficient refrigerant flow and proper oil return, which are vital for the longevity of the compressor. Each line is wrapped in high-density thermal insulation to prevent energy loss and eliminate "sweating" or dripping in ceiling plenums. By enabling remote placement of the condenser, this kit allows you to remove heat and operational noise from your kitchen or dining environment.

  • Model Number: RC53 (Genuine Manitowoc Accessory)
  • Length: 50 Feet (15.24 Meters)
  • Compatibility: Designed exclusively for CVDF1400 and CVDF1800 Remote Condensing Units
  • System Support: Optimized for QuietQube® iF1400C, i-1470C, iF1800C, and i-1870C Series
  • Construction: Premium heavy-gauge copper tubing with industrial-grade insulation
  • Type: Non-precharged (Requires professional field-brazing and evacuation)
  • Application: Facilitates remote condenser mounting to lower indoor HVAC costs and noise
  • Durability: Weather-resistant protective sleeving for long-term outdoor exposure
Technician's Note: The RC53 is a heavy-duty line set required for the high-BTU loads of 1,400lb and 1,800lb systems. Because these lines are not pre-charged, a certified HVAC/R technician must perform the installation, including brazing with a nitrogen purge and pulling a deep vacuum to at least 500 microns. If the installation requires a vertical rise of more than 20 feet, an S-Trap must be installed to prevent oil from logging in the evaporator. Always ensure the insulation joints are sealed with UV-rated tape to prevent moisture from corroding the copper over time.
