Anleitung Zusammenfassung
! CAUTION PROPERTY DAMAGE HAZARD Failure to follow this caution may result in property damage R-410A systems operate at higher pressures than R-22 systems. When working with R-410A systems, use only service equipment and replacement components specifically rated or approved for R-410A service. Check local codes for regulations concerning zoning, noise, platforms, and other issues. Locate unit away from fresh air intakes, vents, or bedroom windows. Noise may carry into the openings and disturb people inside. Locate unit in a well drained area, or support unit high enough so that water runoff will not enter the unit. Locate unit away from areas where heat, lint, or exhaust fumes will be discharged onto unit (as from dryer vents). CLEARANCES Locate unit away from recessed or confined areas where recirculation of discharge air may occur (refer to CLEARANCES section of this document). Roof-top installation is acceptable providing the roof will support the unit and provisions are made for water drainage and noise/vibration dampening. NOTE: Roof mounted units exposed to wind may require wind baffles. Consult the manufacturer for additional information. Nominal minimum clearances are 48 inches above unit for discharge air and 18 inches on each side of the coil for intake air. Clearance on any one side of the coil (normally between unit and structure) may be reduced to 6 inches. Nominal minimum clearances are based on a solid parallel object such as a wall or roof overhang. The clearance may be reduced for a single object with small surface area, such as the end of a wall, outside corner of a wall, fence section, post, etc. As a general rule, the minimum clearance from the unit should equal the width of the object. For example, a 6 inch fence post should be a minimum of 6 inches from the unit. Do not install unit under roof overhangs unless gutters are present. A minimum vertical clearance of 48 inches is required to the overhang. Inside corner locations on single story structures require evaluation. Large overhanging soffits may cause air recirculation in a corner area even though recommended minimum clearances are maintained. As a guide, locate the unit far enough out so that half of the discharge grille is out from under the soffit. When placing two or more units side-by-side, provide a minimum of 18 inches between units. Provide minimum service clearance of 24 inches from control box corner and side service panel.

A. GROUND LEVEL INSTALLATION The unit must be level and supported above grade by beams, platform, or a pad. Platform or pad can be of open or solid construction but should be of permanent materials such as concrete, bricks, blocks, steel, or pressure- treated timbers approved for ground contact. Soil conditions must be considered so that the platform or pad does not shift or settle and leave the unit partially supported. Minimum pad dimensions are shown in Figure 2. If beams or an open platform are used for support, it is recommended that the soil be treated or area be graveled to reduce the growth of grasses and weeds. To minimize vibration or noise transmission, it is recommended that supports not be in contact with the building structure. However, slabs on grade constructions with an extended pad are normally acceptable. ! CAUTION PROPERTY DAMAGE HAZARD Failure to follow this caution may result in property damage. Top surface of platform must be above estimated snowfall level to prevent snow blocking coil and to allow water melt to drain from unit. B. ROOF TOP INSTALLATION This type of installation is not recommended on wood frame structures where low noise levels are required. Supporting structure or platform for the unit must be level. If installation is on a flat roof, locate unit minimum 6 inches above roof level. Place the unit over one or more load bearing walls. If there are several units, mount them on platforms that are self-supporting and span several load bearing walls. These suggestions are to minimize noise and vibration transmission through the structure. If the structure is a home or apartment, avoid locating the unit over bedrooms or study. NOTE: When unit is to be installed on a bonded guaranteed roof, a release must be obtained from the building owner to free the installer from all liabilities. C. FASTENING UNIT DOWN If conditions or local codes require the unit be attached in place, remove the knockouts in the base pan and install tie do...
