REV: 04-29-25 LF <br />HVAC OVERHEAD COVER PAINT <br />The overhead HVAC cover shall be painted with a multi-tone onyx black texture finish. <br />A/C CONDENSER LOCATION <br />A roof mounted A/C condenser shall be installed centered on the cab forward of the raised roof <br />against the slope rise. <br />A/C COMPRESSOR <br />The air-conditioning compressor shall be a belt driven, engine mounted compressor. The <br />compressor shall be compatible with R134-a refrigerant. <br />**The chassis manufacturer recommends that the overall climate system performance be <br />based off third-party testing in accordance with the Society of Automotive Engineering <br />standards as a complete system. <br />Individual component level ratings are not an accurate indicator of the performance <br />capability of the completed system. <br />Refrigerant Compressor displacement: 19.1 cubic inches per revolution. <br />UNDER CAB INSULATION <br />The underside of the cab tunnel surrounding the engine shall be lined with multi-layer insulation, <br />engineered for application inside diesel engine compartments. <br />The insulation shall act as a noise barrier, absorbing noise thus keeping the decibel level in the <br />cab well within NFPA recommendations. As an additional benefit, the insulation shall assist in <br />sustaining the desired temperature within the cab interior. <br />The engine tunnel insulation shall measure approximately 0.30 inch thick including a multi-layer <br />foil faced glass cloth and polyester fiber layer. The foil surface acts as protection against heat, <br />moisture and other contaminants. The insulation shall meet or exceed FMVSS 302 flammability <br />test. <br />The insulation shall be cut precisely to fit each section and sealed for additional heat and sound <br />deflection. The insulation shall be held in place by acrylic pressure sensitive adhesive. <br />INTERIOR TRIM FLOOR <br />The floor of the cab shall be covered with a multi-layer mat consisting of 0.25 inch thick sound <br />absorbing closed cell foam with a 0.06 inch thick non-slip vinyl surface with a pebble grain finish. <br />The covering shall be held in place by a pressure sensitive adhesive and a cast aluminum trim <br />piece at each cab door opening. All exposed seams shall be sealed with silicone caulk matching <br />the color of the floor mat to reduce the chance of moisture and debris retention. <br />ATTY/AGR.2025.089/Fire Apparatus Solutions (Purchase of Spartan-LTC 105' TDA) (Page 56 of 150)
