The YT Model Multi-Positional Vertical Packaged Unit uses an all-aluminum microchannel air coil. Elastomeric compressor isolation pads separate the Copeland UltraTech 2-stage Scroll compressor from the unit. These pads isolate and dissipate vibration at the source. In addition, internal copper tubing employs an enhanced shock-loop design, which also prevents compressor vibration from transmitting through other internal components, and improves the durability of the internal refrigeration circuit. High-density, closed-cell foam insulation is used throughout the unit to absorb sound. YT vertical packaged models are multi-positional, meaning a single unit can be configured for left- or right-hand return in the upflow position with minimal effort and tools. Improved digital controls can be mounted on the top or side of the unit in either return position. The control box has a status window that allows for visibility of the unit status lights without opening the cover.
