4 Tons
LG's KUSXB481A / KNSLB481A heat pump system has an output of 4 tons, generally enough to heat and cool a medium to large house in ideal climates. This system is capable of cooling in outdoor temperatures as high as 118°F and heating down to -4°F. Supplemental heat kits are available if backup electric heat is necessary for your area.
High Efficiency Inverter Technology
LG's heat pump condensers are built with an advanced inverter R1 scroll compressor. This innovative technology eliminates the harsh "on-off" cycling seen on standard systems, creating a highly efficient heat pump system capable of withstanding colder outdoor temperatures. Through this compressor, the heat pump is capable of modulating its own speed to match the real-time thermal load of your home, maintaining steady temperatures and reducing wear on mechanical components.
Warranty
This system includes a 5-year parts warranty and 5-year compressor warranty from the date of purchase. Register within 60 days of residential installation to upgrade to a 10-year parts and 10-year compressor warranty for the original homeowner, starting from the installation date.

Santa Fe Ultra70 Whole-Home Ventilating Dehumidifier, 70-pint | R454BOVERVIEW
The Santa Fe Ultra70 was the first compact whole house ventilating dehumidifier built for tight, low-clearance installs. It removes up to 70 pints of moisture per day and covers homes up to 1,800 square feet, which makes it a strong match for smaller houses, condos, and apartments.
Ducted into your HVAC system, the Ultra70 controls humidity everywhere at once instead of one room at a time. That means no musty basement smell, no clammy upstairs bedrooms, and no conditions that let mold and wood rot get started.
The cabinet measures 12" W x 12" H x 28" L and converts between horizontal and vertical airflow discharge, so it works in mechanical rooms, closets, attics, basements, and crawl spaces alike. Now running R454B refrigerant, it exceeds Department of Energy efficiency standards and is built at Santa Fe's headquarters in Madison, Wisconsin.
Key Features:
- 70 Pints Per Day – Whole-home moisture control for spaces up to 1,800 sq. ft.
- Optional Fresh Air Ventilation – Duct outdoor air in to dilute indoor pollutants
- MERV-13 Filtration – Standard filter captures fine airborne particles
- Convertible Discharge – Rotate the panel for horizontal or vertical airflow
- Compact 12" x 12" x 28" Cabinet – Fits where standard units can't
- R454B Refrigerant – Exceeds DOE efficiency standards
- 115V / 5.4 Amps – Plugs into a standard grounded outlet
- Made in Madison, Wisconsin – Heavy-duty steel construction
Customized Installation and Operation
The Ultra70 gives you three ways to install it. Tie it into your existing HVAC system with a dedicated 8" return and a supply connection with backdraft damper. Run it on its own separate ductwork. Or set it freestanding in a basement or crawl space when ducting isn't practical.
Both the return air inlet and supply air outlet use 8" duct collars. The back panel comes configured for horizontal flow through and rotates for vertical flow through with a T20 torx bit, which is what lets the same unit work in an attic, a closet, or under a floor.
Fresh air ventilation is optional and simple to add. A "T" into the inlet duct brings outdoor air into the system to dilute pollutants and maintain normal oxygen levels indoors, and the volume is adjustable with a range of dampers and controls.
- HVAC Integration – Dedicated return plus ducted supply to the air handler
- Dedicated Ducting – Runs on its own duct system independent of HVAC
- Freestanding Operation – Works standalone in basements and crawl spaces
- Optional Outdoor Air – Ventilation duct T's into the inlet, regulated by dampers and controls
- Continuous Drain – Gravity drainage, no manual emptying
Warranty Information
Santa Fe warrants the Ultra70 Dehumidifier to be free from defects in materials and workmanship. The unit includes a 5-year limited warranty, with extended coverage on select components. Warranty coverage may vary based on installation, application, and registration requirements. Refer to the manufacturer’s documentation for complete warranty details.
Premium Materials & Construction
Dehumidifiers live in the roughest parts of a house. The Ultra70 is built from heavy-duty steel with components chosen to hold up to damp air, dust, and temperature swings over years of runtime.
Inside, a high-efficiency refrigeration coil, compressor, and fan work together to pull more moisture using about 15% less energy than comparably sized units. The R454B refrigerant charge lowers the environmental impact compared to earlier models while keeping performance where it needs to be.
The MERV-13 filter comes standard and pulls fine particles out of the airstream as the unit works. Vacuum it regularly and swap it every six months. The unit operates between 49°F and 95°F, plugs into a standard 115V grounded outlet at 5.4 amps, and ships with a 9 ft. cord.
