The contractor must hold appropriate California State Licensing Board (CSLB) licenses (C20 or C43 and C61/D34) and must comply with Title 24 building, mechanical, electrical, fire, and seismic codes. • Install two 21‑inch sliding‑track exhaust fans, associated ductwork, and a 5 hp VFD‑controlled blower. • Provide all electrical connections, safety disconnects, and UL‑listed control panels, ensuring compliance with OSHA and state fire‑code requirements. • Deliver complete design documentation, obtain required permits, and provide manufacturer‑certified commissioning and a one‑year warranty.
