Craftsmanship/Quality

• The slim-design cabinet allows for installation in even the tightest areas, making it perfect for space-constrained environments such as zero lot line homes.
• Built for durability and reliability, the EL18KSLV is made with a heavy-duty steel cabinet to ensure that your unit resists the elements for years to come.
• Braze-free installation flexibility – our 2025 compliant systems can accommodate braze-free fittings, giving you greater flexibility when installing.

Safety/Reliability

• Our 2025 compliant systems feature a Refrigerant Detection System (RDS) mandated by the new safety code created for A2L, or mildly flammable refrigerants. The RDS is required for systems with over four pounds of refrigerant and consists of two components: the sensor, which detects leaks, and the control board, which interrupts unit operation and activates the indoor blower to disperse leaks, ensuring safe operation.

This product uses R-454B refrigerant, which meets the 2025 EPA regulations for lower global warming potential (GWP) refrigerants.
