All parts should be carefully inspected to determine if any damage was incurred in shipment. Any shortage and/or claims for damage should be immediately reported to the delivering carrier, followed by filing a claim for shortages and/or damages. When uncrating, care should be taken to prevent damage. Heavy equipment should be left on its shipping base until it has been moved to the final location. Rigging and Moving Units The exact method of handling and setting the unit depends on available equipment, size of unit, final location and other variables. It is the judgement of the riggers and movers to determine the specific method of handling each unit. All units are shipped on heavy skids and enclosed in open crating. Generally, it is advisable to bring the unit as close to its final location as possible before removing crating. Units are provided with lifting ears near the four corners. Under no circumstances should the coil headers or return bends be used for moving these units. NOTE FOR ALL MODELS: Spreader bars must be used (contractor-supplied). Safety slings should be used when making lift. Installation Requirements NOTE: Installation and maintenance to be performed only by qualified personnel who are familiar with local codes and regulations and are experienced with this type of equipment. CAUTION: Sharp edges and coil surfaces are a potential injury hazard. Avoid contact with them. WARNING: This equipment may contain a substance that harms public health and the environment by destroying ozone in the upper atmosphere. Venting of certain refrigerants to the atmosphere may be illegal in your location. Refrigerant recovery devices should be used when installing or servicing this product. Consult your local codes for requirements in your location. WARNING: Refrigerant can be harmful if it is inhaled. Refrigerant must be used and recovered responsibly. Failure to follow this warning may result in personal injury or death. Unit Location Units are designed for outdoor application and may be mounted on a roof or concrete slab (ground-level installation). Concrete slabs used for unit mounting should be installed level and be properly supported to prevent settling. A one-piece concrete slab with footings extending below the frost line is recommended. Roof-mounted units should be installed level on steel channels or an I-beam frame to support the unit above the roof. Use of vibration pads or isolators is recommended. The roof must be strong enough to support the weight of the unit. Figure 1: Suggested Rigging © 2007 Heatcraft Refrigeration Products LLC Remote Air-Cooled Condenser Remote Air-Cooled Condenser Installation and Operations Manual, August 2007 The condenser should be located no closer than four feet from any wall or other obstruction to provide sufficient clearance for air entrance. Do not attach ductwork to the coil inlet or fan outlet. Care should be taken to avoid air recirculation conditions that can be caused by sight screening, walls, etc. Keep unit fan discharge away from any building air intakes. Space and Location Requirements The most important aspect in selecting a location for air-cooled equipment is a supply of ambient air to the condenser and the adequate removal of heated air from the condenser area. If the requirement for adequate air circulation is not adhered to, higher head pressures will result, creating poor operation and possible failure of equipment. Units must not be located in the vicinity of steam, hot air or fume exhausts. Walls or Obstructions The unit should be located so that air may circulate freely and not be recirculated. For proper air flow and access, all sides of the unit should be a minimum of the width of the unit away from any wall or obstruction. It is preferable for this distance be increased whenever possible. Care should be taken to see that ample room is left for maintenance through access doors and panels. Overhead obstructions are not p...
