About this file
This document is a two-page architectural plan for Building 9310, detailing demolition and new work for an HVAC system upgrade. The demolition plan involves removing existing ceiling boxes, exposed Romex wiring, 12 incandescent fixtures, and switches, while preserving the existing ½" plywood backing and exterior fire light. The building's interior walls and ceiling will be partially sprayed with open-cell foam insulation.
The new work plan specifies installing a mini-split system with specific Friedrich model components: a 24,000 BTUH, 208/230V inverter (FPHMR24A3A) and an air handler (FPHFW24A3B), mounted at 7'-6" above finished floor. Additional improvements include six 8' weatherproof LED fixtures with new EMT conduit conductors, a double-gang cast box with two 20A switches, and an exterior NEMA 3R disconnect with a GFIC. The inverter will be mounted on an exterior metal rack at 2'-0" above grade, with line sets routed externally and covered with a mill-finished aluminum cover. The work will be powered from the existing 100 AMP main panel.
