The filter section holds pre-filters of (3) 16x20 and (3) 20x20 plus main filters of (3) 16x20 and (3) 20x20. The chilled water coil (28MCV828FAA059BLNA) and hot water coil (28MHV228HAA059BLNA) are each rated 300 PSIG maximum operating pressure at 200 degrees F. The supply fan section uses two 5 HP, 1800 RPM motors rated 460V/3-phase/60 Hz, FLA/MCA/MOCP 6.6/8.3/10 each, with a maximum continuous draw of 15.4 amps. Controls and electrical visible in the photos include an ABB HVAC variable frequency drive with keypad mounted on the unit casing, a fan-mounted disconnect switch, an Eaton 30A/600V heavy duty safety switch fed from panel 3DPH2 (circuits 1, 3, 5), and a junction/control enclosure.
