These units leave the factory compliant with low leak requirements of less than 2% cabinet leakage rate at 0.5 inches W.C. and 1.4% cabinet leakage rate at 0.5 inches W.C. when tested in accordance with ASHRAE 193 standard.  \nAll models are designed for maximum flexibility and can be used for upflow, horizontal left or right, and downflow applications (accessory kit required for downflow) .  \nWAPL models are available for system sizes 1−1/2 through 4 tons (18,000 − 48,000 BTUH) nominal cooling capacity. All models use an ECM integral electronically commutated motor for efficiency and use a piston metering device. WAHL and WAXL models are available for system sizes 1−1/2 through 5 tons (18,000 − 60,000 BTUH) nominal cooling capacity. All models use an ECM integral electronically communtated motor for efficiency and have a factory installed and appropriately sized hard shut−off TXV metering device are for R−410A refrigerant ONLY.
