About this file
This is a technical drawing set for HVAC repairs at the Snoqualmie Visitor Center & Office, located at the North Bend compound within the Mt. Baker-Snoqualmie National Forest in Washington State. The project is under the jurisdiction of the United States Department of Agriculture Forest Service, Pacific Northwest Region (R06), Snoqualmie Ranger District.
The primary work involves replacing two COM14908 compressors in a Trane TTA120E30RAA air conditioning unit serving Building 2031 at the North Bend compound. The condenser unit operates at 208V, 3-phase, 60Hz on R-410A refrigerant. Each compressor has specifications including 4 horsepower, 4.25-ton refrigeration capacity, 3500 RPM, 13.6 amperes, and requires POE (polyester) oil. The HVAC system currently operates with one compressor functional. Indoor units are located in the building attic, with a gas furnace positioned in the utility room. The drawings include site maps identifying the North Bend compound layout, a detailed HVAC arrangement plan view of Building 2031 showing ductwork distribution to multiple offices and common areas, and photographs of the existing condenser unit. The contractor is required to verify compressor part numbers before ordering replacements. The drawing set was prepared as of April 17, 2026, by K. Timm, Forest Engineer.
