LSC Ludwig Structural Consulting September 19, 2024 Mr. Karl Christensen Legacy One Heating 4403 Russell Rd., Suite 110 Mukilteo, WA 98275 karl@legacyoneheating.net Subject: Rooftop Mechanical Unit Anchorage 23805 Highway 99, Edmonds, WA 98026 Dear Karl: Ludwig Structural Consulting (LSC) has performed an analysis of the wind and seismic forces and determined anchorage connection requirements for the proposed rooftop 5-ton Trane 4WCC4060 rooftop mechanical unit at 23805 Highway 99. Wind and seismic forces were determined using ASCE 7-16 and design parameters determined from the ASCE design hazards website. LSC has determined that the following minimum connections are required to 1) secure the mechanical unit to the curb adapter, and 2) secure the curb adapter to the existing curb. LSC understands that the curb adapter, existing curb, and mechanical unit housing are built with minimum 16-gauge metal. Required anchorage of the mechanical unit to the curb adapter shall meet the following requirements: Connection straps, including hold-down brackets, shall be 16-gauge minimum. A minimum of (4) connection straps shall be used. Connection straps shall be located within 4-inches of the mechanical unit corners. Connection straps shall be secured to the mechanical unit with a minimum of (2) #10 or larger sheet metal screws at each strap. Connection straps shall be secured to the curb adapter with a minimum of (2) #10 or larger sheet metal screws at each strap. Required anchorage of the curb adapter to the existing curb shall meet the following requirements: 1. A minimum of (3) #10 or larger sheet metal screws are required on each side to anchor the curb adapter to the existing curb. Ludwig Structural Consulting, L L C 4701 SW Admiral Way • Suite 325 • Seattle, WA 98116 ( 2 0 6 ) 4 0 2 - 4 2 9 0 2. Locate one screw within 2-inches of each corner. Remaining screws shall be evenly spaced along each edge. An installation of the mechanical unit and adapter curb in accordance with the requirements noted above will be able to withstand code -required wind and seismic forces.

All units shall be factory assembled, piped, internally wired and fully charged with refrigerant. Units shall be certified to UL Standard 1995. All units shall be factory run tested to check cooling operation, fan and blower rotation and control or TXV sequence. Units shall be designed to operate at ambient temperatures between 1151F and 55°F in cooling as manufactured. Cooling performance shall be rated in accordance with AHRI standards. Unit Casing All components shall be mounted in a weather - resistant steel cabinet with an enamel finish. Access panels shall be provided for unit controls and indoor coil and fans. Indoor air section compartment shall be completely insulated with fireproof, permanent, odorless fiber material. Knockouts shall be provided for utility and control connections. Drain connections shall be provided to accommodate indoor water runoff. Compressor The compressor shall be hermetically sealed, high efficiency scroll compressors. Internal overcurrent and over temperature protection, internal pressure relief shall be standard. Other features include centrifugal oil pump, low vibration and noise. Refrigeration System All units shall have refrigerant control. Service pressure tap ports and a refrigerant line filter shall be standard. Evaporator Coil Internally enhanced 3/8" OD seamless copper tubing mechanically bonded to aluminum fins, factory pressure and leak tested at 480 — 650 psig. All units have TXV to control refrigerant flow. Condenser Coil The Spine Fin TM condenser coil shall be continuously wrapped, corrosion resistant all aluminum with minimum brazed joints. This coil is 3/8" OD seamless aluminum tubing glued to a continuous aluminum fin Coils are lab tested to withstand 2.000 pounds of pressure per square inch. The outdoor coil provides low airflow resistance and efficient heat transfer. The coil is protected on all four sides by louvered panels. Indoor Air Fan Constant Torgue, forward -curved, centrifugal wheel in a Composite Vortica ® Blower housing. Motor shall have thermal overload protection and permanently lubricated motor bearings. Motor/blower assembly isolated from unit with rubber mounts. Outdoor Fan One direct -drive, statically and dynamically balanced propeller fan shall be used in a draw -through vertical discharge configuration. Permanently lubricated weather proof motor shall have built-in thermal overload protection. System Controls System controls include condenser fan, evaporator fan and compressor contactors. Accessories Roof Curb The roof curb shall be designed to mate with the unit and provide support and complete weathertight installation when properly installed. Adhesive back polyurethane sealing strips shall be provided to ensure an airtight seal between supply and return openings of the curb and unit. The roof curb design allows field fabricated ductwork to be connected directly to the curb. Curb ships knocked down for field assembly, and includes factory installed wood nailer strips. Electric Heaters Each heater assembly shall include power supply fusing if over 48 amps, automatic resetting limit switches and heat limiters for thermal protection. Heaters shall be provided with polarized plugs for quick connection to unit low voltage wiring. Electric heat modules shall be UL listed. Single Source Power Entry This accessory when used with electric heat accessory shall allow single source power connection to unit and heater combination. Single source power entry kits shall have specific matching heater(s). Kit shall include high voltage terminal blocks, fuse blocks and fuses, cut -to -length interconnecting wiring, and junction box (if required) to provide power sources with fuse protection as required for both the unit and accessory heater. Kit components shall install within the heater cabinet in the heater access section. Single source branch power circuit shall be protected and wired in accordance with local codes. 4WCC4060E-SUB-1 A -EN 11 Mechanical Specifications Fully Modulating Economizer This accessory shall be field installed and be composed of the following items: 0-100 % fresh air damper, damper drive motor, fixed dry bulb enthalpy control, and low voltage pigtails for electrical connections. Solid state enthalpy or differential enthalpy control is optional. Economizer operations shall be controlled by the preset position of the enthalpy control. A barometric relief damper shall be standard with the economizer and provide a pressure operated damper that shall be gravity closing and prohibit entrance of outside air on equipment "off" cycle. Economizer requires BAYRLAY004A relay kit to interface the economizer to the heat pump. Manual Outside Air Dampers Rain hood and screen shall be field installed. Suitable for up to 25% outside air. Start Kit Extra compressor starting capacity for single phase equipment. Control Options Standard Indoor Thermostats Two stage heating/cooling or one stage heating/ cooling thermostats shall be available in either manual or automatic changeover. Programmable Electronic Night Setting Thermostat Programmable electronic thermostat shall provide heating setback and cooling setup with 7—day programming capability. 1H/1C or 21-1/2C models available. 12 4WCC4060E-SUB-1A-EN About Trane and American Standard Heating and Air Conditioning Trane and American Standard create comfortable, energy efficient indoor environments for residential applications.
