About the AA8145

Where the AA8145 fits

Mounting and drainage accessories are what keep equipment level, dry and serviceable for its whole life. The AA8145 is a small part of the job that prevents the expensive callbacks: rusted cabinets, overflowing pans and vibration noise.

A correctly set and drained installation is quieter, lasts longer and passes inspection the first time. Pads keep condensers level so the compressor oil returns properly; pans and switches stop the ceiling stain that turns a small drain clog into a drywall repair.

Background reading: the U.S. Department of Energy guide to duct losses.

What to check before you order

• Dimensions against the equipment footprint.
• Drain connection size and slope to the drain line.
• Load rating for the equipment weight.

Installation and service notes

Set pads and stands level on compacted ground or a proper base, keep drain pans sloped to the outlet, and install float switches so they trip before water reaches the pan rim. Vibration isolation pads go under the equipment feet, not under the pad.
