3 GUIDE SPECIFICATIONS Magic Aire Fan Coil Unit HVAC Guide Specifications Size Range: 200 to 1200 Nominal CFM Magic Aire Model CE Part 1 General 1.01 SYSTEM DESCRIPTION Horizontal, 2-pipe or 4-pipe, room fan coil unit with painted finish cabinet for exposed installation or ducting QUALITY ASSURANCE Unit shall be tested in accordance with ARI Standard 440 and base unit ETL certified. Each coil shall be factory tested for leakage at 450 psig air pressure with coil submerged in water. Insulation and adhesive shall meet NFPA-90A requirements for flame spread and smoke generation. All equipment wiring shall comply with NEC requirements DELIVERY, STORAGE AND HANDLING Each unit shall be individually packaged from point of manufacture. Unit shall be handled and stored in accordance with the manufacturer s instructions. Part 2 Product 2.01 EQUIPMENT General: Factory-assembled, horizontal, blow-thru type fan coil for exposed ceiling or ducted installations. Unit shall be complete with water coil(s), fan(s), motor(s), drain pan, and all required wiring, piping, controls and special features. A. Base Unit: 1. Casing to consist of heavy gauge galvanized steel insulated with 1/2 fiberglass Tufskin insulation. Units shall pass 500 hour salt spray test as described in ASTM B Cabinet shall include a removable bottom access panel with stamped return-air grille or ducted return air, filter rack and 1-in. fiberglass throwaway filter. The panel shall be fastened with slotted head, positive-locking quarter-turn fasteners. The cabinet shall be coated with a Polar Ice baked finish. 3. The drain pan shall be constructed of galvanized steel extending the entire length and width of the coil(s) and shall be pitched for drainage. The drain connection shall be ¾ FPT. B. Fans: Direct-driven, double-width fan wheels with forward curved blades shall be statically and dynamically balanced. The housing shall be constructed of heavy gauge galvanized steel with die-formed inlet cones. Fan wheels shall be constructed of galvanized steel. C. Coils: 1. Standard base unit shall be equipped with a 3-row, 4-row or 5-row coil for installation in a 2 or 4-pipe system. Hydronic coil options include split heating/cooling coils in combinations not exceeding 5 rows. 2. Factory installed electric resistance heating coils in may be 1.5 to kw depending on unit size and voltage. 3. All coils shall have 3/8-in. copper tubes and aluminum fins. Coil fins are mechanically bonded to tube joints. The copper tubes comply with the ASTM B-75. The fin thickness is in and tube thickness is 0.0-in. All coils are tested with air under water. 4. Unit with electric heat shall have electric resistance heaters mounted on the entering air side of the water coil. Heaters shall include high limit cutout with auto reset and contactor. 5. When fan motor and electric heater are selected at the same voltage and connected to a single power source, a junction box and fuse shall be factory furnished and installed to protect the motor and control circuit. D. Controls and Safeties: Unit shall be furnished with an optional 3-speed, 4-position fan switch on a wall plate for field mounting. The fan motor(s) shall be equipped with integral automatic temperature reset for motor protection. E. Operating Characteristics: 1. A unit with single hydronic coil installed in a 2-pipe system shall be capable of providing heating or cooling as determined by the operating mode of the central water supply system. 2. A unit with two hydronic coils installed in a 4-pipe system shall be capable of providing heating and cooling, controlled as determined by field-provided and installed valves and controls. 3. Electrical Requirements: The unit power supply shall be single phase, 60 Hz. The standard unit is 120 volt, but 208/240V and 277V options are available. F. Motor(s): Fan motors shall be 3-speed; permanent split capacitor type, with sleeve type bearings and factory-sealed oil reservoirs to ensure lubrication. Page 3
