Resumen del manual
Units are air cooled, designed for outdoor installation, and may be connected into existing duct system. Required connections include air ducts, condensate drain, and high- and low-voltage wiring. A field-supplied filter box must be installed in return air duct. When optional electric heaters are being installed, see instructions beginning on page 8 of this publication for procedures. TRANSPORTATION DAMAGE File claim with shipping company if shipment is damaged or incomplete. Move unit to installation site in upright position. Important—Read Before Installing 1. Check all local codes and ordinances that could affect installation of equipment. 2. Be sure power supply available (voltage, hertz, and phase) corresponds to that specified on unit rating plate. 3. Check electrical service provided by utility for building to be sure service capacity is sufficient to handle load imposed by unit. 4. Refer to dimensional drawing for locations of electrical, condensate drain, and duct connections before setting unit in place. Installation consists of the following steps: I. Locating and Mounting Unit II. Connecting Ductwork III. Connecting Condensate Drain IV. Electrical Connections V. Startup and Adjustment VI. Maintenance VII. Instructions to Owner i. LOCATING AND MOUNTING UNIT Place unit on a solid, level, concrete pad. Pad should be minimum of 3 inches high, extend about 6 inches from both sides and front of unit, and must not extend more than 1 inch from back (duct side) of unit. Insert sheet of tar-base construction felt paper between unit and pad. Unit does not need to be secured to pad because there are no refrigerant lines extending outside of unit that could be damaged. Be sure grass and shrubs do not interfere with condenser airstream. If necessary, extend gravel apron around pad. Place duct side against building structure so ductwork cannot be seen from outside. When installing unit, allow sufficient space for condenser airflow clearance, wiring, and servicing unit. See Figure 2. Position unit so water from roof will not pour directly on top of unit. Do not locate unit under eaves. Recommended minimum service clearance: 18 inches all sides except duct side 0 inches bottom 36 inches top Cancels: 39559D47 39559DP61 6/1/74 Figure 1—Model 559B II. CONNECTING DUCTWORK Flanges are provided on unit for duct connections. See Figure 2 for unit connection sizes and locations. Use weathertight connectors between ductwork and unit to prevent transmission of vibration. Ductwork should be selected and sized according to Part 2 of Bryant Air Distribution Manual. All ductwork in unconditioned space should be insulated and weatherproof if used outdoors.

When electric heaters are installed, use an asbestos (or similar heat-resistant material) connector between ductwork and unit supply duct connection. When flexible duct is used, friction loss in straight runs is approximately double amount found in Bryant Air Distribution Manual, Part 2, for air duct design. It is recommended that rigid elbows should be used for bends. If rigid elbows are not used, ratio of centerline bend, radius to duct diameter (R/D) should be at least 1.5 for minimum friction loss. If rectangular ducts are used over unit round connections, unit entering pressure loss must be considered when designing system. \\ llii imi ill ill Imli--. in .in.i shown in It is also recommended that abrupt duct expansions and contractions be avoided. NOTE: Mobile home duct kits (which include a return air filter box, filter, floor grille, flexible duct sections, and installation hardware) are available for mobile home installation. See your Bryant Distributor. Mobile Home Duct Design Design duct system to have friction loss of between 0.25 in. wc and 0.70 in. wc for proper unit operation. Insulated flexible ductwork (1-ft inside diameter) of weatherproof type is recommended. Do not reduce duct inside diameter below 1 ft. Combined length of supply and return ducts should not exceed 20 ft, with minimum supply duct length DIMENSIONS IN INCHES SEE PICTORIAL VIEW SIZE C D E F G H J 024 17-5/8 12 12 10-1/4 14-1/2 8-5/8 25-5/16 030 17-5/8 12 12 10-1/4 14-1/2 8-5/8 25-5/16 036 19-5/8 14 14 11-1/4 16-1/2 8-5/8 25-5/16 042 27-5/8 14 14 12-1/4 24-1/2 9-5/8 24-5/16 048 27-5/8 14 14 12-1/4 24-1/2 9-5/8 24-5/16 A72339 LOW-VOLT CONN (2) KNOCKOUTS Figure 2 — Dimensional Drawing DETAIL B (SUPPLY ASSEMBLY) DETAIL A (RETURN ASSEMBLY) (7) RETURN AIR FLOOR GRILLE @ 20x25 xl DISPOSABLE FILTER (?)
