Icp N5H5S42CKAAA Heat Pump Condenser 3.5 Ton 14.3 Seer R454B

Product Description

The INTERNATIONAL COMFORT PRODUCTS N5H5S42CKAAA is a 3.5-ton single-stage heat pump condensing unit rated at 14.3 SEER and designed for split-system residential cooling and heating applications. Operating on 208/230-volt, single-phase power, it uses R454B refrigerant, a non-ozone-depleting refrigerant with low global warming potential. The unit is built around a scroll compressor and features an internal pressure relief valve and internal thermal overload protection for added reliability. Heavy-gauge sheet metal construction and a dense wire coil guard provide durable weather resistance in outdoor installations. Licensed HVAC technicians install and commission this unit.

The N5H5S42CKAAA is suited for residential split-system applications where a 3.5-ton cooling and heating load is required. It delivers 42,000 BTU/h in both cooling and heating modes and is rated across a SEER2 range of 13.8 to 17.0 and an EER2 range of 11.2 to 14.5, depending on the matched indoor system configuration. The unit supports programmable or standard thermostat controls and is compatible with indoor air quality accessories. It is intended for standard outdoor pad or platform installations where single-phase utility power is available.
