The water lines will be permanently capped to prevent future leaks. • Disconnect and remove the twinned furnaces for system AHU-4 and discard off -site. • Modify the existing return air base for AHU-4 as required to accommodate the new furnaces. • Furnish and install two (2) Carrier 96% efficient, 60k BTU furnaces for system AHU-4 and set on the original return air plenum base. o Carrier Furnace M#: 59SC6A060M17-16 • Furnish and install two (2) Carrier twinned, cased vertical coils with thermal expansion valves (TXV's) and set on top of the new and existing furnaces. o Carrier Coil M#: CAVTCOIL408A00 • Furnish and install two (2) Carrier 7.5 Ton, 460V/30, single circuit condensers with two -stage compressors and set on the wood supports on the roof. o New wood supports furnished and installed by Slatile.
