Anleitung Zusammenfassung
If a plenum return is used on a vertical unit, the return should be ducted through the roof deck to comply with applicable fire codes. Step 6 — Rig and Place Unit Keep unit upright and do not drop. Spreader bars are not required if top crating is left on unit. Rollers may be used to move unit across a roof. Level by using unit frame as a reference. See Table 1 and Fig. 7 for additional information. Lifting holes are provided in base rails as shown in Fig. 7. Refer to rigging instructions on unit. CAUTION! UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage. All panels must be in place when rigging. Unit is not designed for handling by fork truck. Before setting the unit onto the curb, recheck gasketing on curb. 581J C06005 UNIT MAX WEIGHT DIMENSIONS A B C LB KG IN MM IN MM IN MM 581J*07 1200 545 88.0 2235 44.0 1120 41.5 1055 581J*08 1420 645 88.0 2235 44.0 1120 49.5 1255 581J*09 1420 645 88.0 2235 44.0 1120 49.5 1255 581J*12 1665 757 88.0 2235 32.0 815 49.5 1255 NOTES: 1. SPREADER BARS REQUIRED — Top damage will occur if spreader bars are not used. 2. Dimensions in ( ) are in millimeters. 3. Hook rigging shackles through holes in base rail, as shown in detail “A.” Holes in base rails are centered around the unit center of gravity. Use wooden top to prevent rigging straps from damaging unit. Fig. 7 - --Rigging Details 11 12 Positioning on Curb— Position unit on roof curb so that the following clearances are maintained: 1/4 in. (6.4 mm) clearance between the roof curb and the base rail inside the front and back, 0.0 in. clearance between the roof curb and the base rail inside on the duct end of the unit. This will result in the distance between the roof curb and the base rail inside on the condenser end of the unit being approximately equal to Fig. 4 and Fig. 5, section C--C. Although unit is weatherproof, guard against water from higher level runoff and overhangs. Flue vent discharge must have a minimum horizontal clearance of 4 ft (1220 mm) from electric and gas meters, gas regulators, and gas relief equipment. Minimum distance between unit and other electrically live parts is 48 inches (1220 mm). Flue gas can deteriorate building materials. Orient unit such that flue gas will not affect building materials. Locate mechanical draft system flue assembly at least 48 in. (1220 mm) from an adjacent building or combustible material. NOTE: Installation of accessory flue discharge deflector kit will reduce the minimum clearance to combustible material to 18 in. (460 mm). After unit is in position, remove rigging skids and shipping materials. Step 7 — Convert to Horizontal and Connect Ductwork (when required) Unit is shipped in the vertical duct configuration. Unit without factory--installed economizer or return air smoke detector option may be field--converted to horizontal ducted configuration. To convert to horizontal configuration, remove screws from side duct opening covers and remove covers. Using the same screws, install covers on vertical duct openings with the insulation--side down. Seals around duct openings must be tight. See Fig. 8. C06108 Fig. 8 -- Horizontal Conversion Panels Field--supplied flanges should be attached to horizontal duct openings and all ductwork should be secured to the flanges. Insulate and weatherproof all external ductwork, joints, and roof or building openings with counter flashing and mastic in accordance with applicable codes. Do not cover or obscure visibility to the unit’s informative data plate when insulating horizontal ductwork. Step 8 — Install Outside Air Hood Economizer and Two Position Damper Hood Package Removal and Setup -- Factory Option 1. The hood is shipped in knock--down form and must be field assembled. The indoor coil access panel is used as the hood top while the hood sides, divider and filter are packaged together, attached to a metal support tray using plastic stretch wrap, and shipped in the return air compartment behind the indoor coil access panel. The hood assembly’s metal tray is attached to the basepan and also attached to the damper using two plastic tie-- wraps. 2. To gain access to the hood, remove the filter access panel. (See Fig. 9.) FILTER ACCESS PANEL INDOOR COIL ACCESS PANEL C10146 Fig. 9 -- Typical Access Panel Locations 3. Locate the (2) screws holding the metal tray to the basepan and remove. Locate and cut the (2) plastic tie--wraps securing the assembly to the damper. (See Fig. 10) Be careful to not damage any wiring or cut tie--wraps securing any wiring.
