Rooftop Mounted Fan Coil Unit HVAC Guide Specifications Size Range: 800 to 8000 Nominal CFM MagicAire Model Number: BR Part 1 — General 1.01 SYSTEM DESCRIPTION Roof or pad mounted, 2-pipe or 4-pipe, belt-driven fan coil unit, suitable for outdoor installation. External parts are to be made with polyurethane based powder coated galvanealed, while internal parts are to be built from heavy gauge galvanized steel casing model fan coil unit for ducted installation, with full access to internal components. 1.02 QUALITY ASSURANCE Each coil shall be factory tested for leakage at minimum of 400 psig air pressure with coil submerged in water. Insulation and adhesive shall meet NFPA-90A requirements for flame spread and smoke generation. 1.03 DELIVERY, STORAGE AND HANDLING Unit shall be handled and stored in accordance with the manufacturer’s instructions. Part 2 — Products 2.01 EQUIPMENT A. General: Factory-assembled, horizontal, draw-thru type rooftop fan coil unit suitable for rooftop or pad mounted outdoor installation. Unit shall be complete with water, DX or steam coil(s); fan(s); motor; belt drive; drain pan; and filters. B. Casing: Construction shall be heavy gauge galvanealed steel, painted with baked on polyurethane based powder coating, colored beige, lined with Tuf-Skin II®, dual density, one-in. thick fiberglass thermal/acoustical insulation. Removable side panels shall be provided for access to the fan/motor and filter assemblies. Internal pipe chase shall be available for coil piping. Condensate line shall be run to outside cabinet. A galvanized steel drain pan shall extend under the full length and width of the coil(s) with a 3/4-in FPT connection. (Optional) 1” double wall construction shall consist of 1” Tuf-Skin II® insulation with 22-ga galvanized steel liner with no fiberglass insulation exposed to the air stream on side and bottom panels. Access panels shall have heavy-duty hinges for improved access. Stainless steel double sloped drain pan is required for double wall option. Roof top panel shall have 2-layers of insulation with 22-ga sheet metal liner. (Optional) Stainless steel drain pan for standard construction. C. Fans: Belt-driven, double-width fan wheels shall have forward-curved blades and be statically and dynamically balanced. Fan drive shall consist of variable-pitch motor pulley, fixed-pitch fan pulley and V-belt. Fans and scrolls shall be of galvanized steel. D. Coils: Unit shall be equipped with a standard capacity (4)-row CW/HW or DX coil for installation in a 2-pipe system. Additional coils shall be provided for installation in a 4-pipe system. Coils shall have 3/8-in. (sizes 08-20) and 1/2-in. (sizes 30-80) copper tubes with aluminum fins bonded to the tubes by mechanical expansion. Coil(s) shall have a working pressure of 400 psig at 200 F. Each coil shall have sweat connections for copper tubes. Water coil(s) shall have manual air vent(s).
E. Coil Options: a. Unit shall be equipped with a high-capacity coil for installation in a 2-pipe system. b. For installation in a 4-pipe CW/HW system, unit shall be equipped with either a 4-row cooling/2-row hot water heating coils or a 4/4, 6/2 (max 8-rows) coils as required. c. Unit shall be equipped with either a standard capacity DX (direct expansion) cooling coil or a high capacity (single or split face) DX cooling coil as required. d. For installation in a 4-pipe system the unit shall be equipped with either a 3 or 4-row DX cooling/2-row heating coil or a 3 or 4/4, 6/2 (max 8-rows) coils as required. (Note: Hot water coil re-heat installations require a heating coil low limit on units with DX cooling). e. Provide (High) (Low) capacity steam distributing coil F. Operating Characteristics: A single-circuit coil unit installed in a 2-pipe CW/HW system shall be capable of providing heating or cooling. DX coils are suitable for R-22, R410A cooling only or R-22 heat pump operation. A two coil unit installed in a 4-pipe system shall be capable of providing sequenced heating and cooling as determined by the controls provided by others. G. Motor(s): Fan motors shall be open, drip-proof, single-speed, 60 Hz, 1750 rpm single or 3-phase, suitable for continuous duty at 104-deg F (40 C) in 115, 208, 230, or 277 volts (60 Hz). Three-phase motors are available in 208, 230, or 460 volts (60 Hz). Single-phase motors shall be provided with resilient mount. Three-phase 575 volt motors are by others. G. Filters: a. 2” throwaway filter(s) shall be installed in the unit. b. (Optional) 2” pleated filter(s), MERV-7, shall be installed as indicated on the equipment schedule. I. Insulation: a. Standard 1-in thick, 1.5-lbs/ft3 Tufskin II®. b. (Optional) Units shall be equipped with 1-in. thick, 1.5-lbs/ft3, Exact-O-Kote® insulation with an immobilized EPA registered, anti-microbial agent to protect the coating from microbial growth. c. (Optional) 7/8” closed cell insulation d. (Optional) 1” double wall construction shall consist of 1” Tufskin® insulation with 22-gauge galvanized steel liner with no fiberglass insulation exposed to the airstreams. Optional Accessories: a. Economizers shall include weatherhood and low leak damper assemblies constructed of steel channel frames with 18 gauge galvanized steel blades, die formed stiffeners and full blade stop. Stainless steel side seals and vinyl blade seals to reduce leakage shall be standard. All hardware shall be zinc plated with brass pivot points and bronze oilite bearings. Shafts shall be corrosion resistant steel. Includes motor, enthalpy control, mixed air sensor and transformer relay for 208/230/1. Economizers ship separate for field assembly to unit. b. Manual fixed outdoor air dampers for 0-35% or 0-100% outdoor air. c. Motorized fixed outdoor air damper 0-100% d. 14-in high roof curb for field assembly. e. (Optional) 16-in high or custom height roof curb.
