The RATIONAL 44.02.221s is a drain hose designed for use with steam generator assemblies in RATIONAL commercial cooking equipment. This component carries condensate and wastewater away from the steam generator, protecting the unit from standing water and maintaining proper drainage during cooking cycles. It is a direct-replacement part sourced from RATIONAL's accessories and service parts line. Licensed commercial appliance technicians and authorized service agents typically handle installation of this component during scheduled maintenance or steam generator service calls.
This drain hose is intended for use in commercial kitchen environments where RATIONAL combi-oven or steam-injection equipment is installed. It fits within the internal drainage system of the steam generator assembly and is typically replaced when signs of cracking, blockage, or leakage are found during inspection. This part is referenced by alternate identifier 4402221S.
Designed as an OEM-style replacement drain hose for RATIONAL commercial steam generator assemblies. Consult the equipment service manual or a RATIONAL authorized service agent to confirm fitment for a specific unit model before ordering.
Installation should be performed by a qualified commercial appliance technician familiar with RATIONAL equipment. Before servicing, power down the unit completely and allow all steam and heat to fully dissipate. Ensure the water supply is shut off and the steam generator has cooled before disconnecting any hoses or drainage components. Follow the manufacturer's service documentation and all applicable local codes throughout the procedure.
