Standard Features: Refrigeration System The refrigeration system is designed with front air breathing for flexible installation. R290 models come with a full-length air duct system. The unit is pre-wired and ready to plug in, operating at 115V/60Hz/1Ph with a NEMA 5-15P plug. It features a large capacity, corrosion-resistant condenser and evaporator coils. The defrost cycle is time-initiated and temperature-terminated, with a defrost heater included. Pressure relief devices allow easy access to the cabinet interior when reopening doors. The self-maintaining, energy-efficient condensate drain pan requires no external drains or electric heaters. R404A models use PSC evaporator fan motors, while R290 models use electronically commutated (ECM) fan motors. The high-performance condenser fan motors ensure efficient compressor ventilation. R290 models also have auto-reverse condenser fan motors for condenser coil cleaning. For full maintenance instructions, refer to the owner's manual. The bottom-mounted, self-contained, and retractable condensing unit uses environmentally friendly R404A refrigerant with zero Ozone Depletion Potential (ODP) and EPA compliant R290 refrigerant with zero ODP and three Global Warming Potential (GWP). The R290 condensing units are replaceable and require no on-site brazing. Alternative refrigerant options are available upon request. Cabinet Construction The cabinet is constructed with a galvanized steel bottom and rear. It is equipped with four 5" swivel casters, with locks on the front set for stability.
