- 3 -Important Note: To assure sufficient air supply and circulation to thecondensing unit, a minimum clearance of 12" above the grill and 3" on eachside and back of the cabinet must be provided (see figure 1). If necessary,special venting or air supply ducts must be installed by the installer for this purpose.Do not at any time obstruct the grill area in front of the cabinet in any way, andnever place or store anything on top of the cabinet machine compartment. Theserules are essential for maximum cooling capacity and long life of refrigeration parts.FIGURE 1MINIMUM CLEARANCE DIMENSIONSFLOOR LOADSThe floor at the final location site must be level, free of vibration and strong enoughto support the total combined weights of your new model plus the maximumproduct load which might be placed into it. A fully loaded reach-in or roll-in modelmay reach 2,000 - 3,000 pounds. To estimate the possible product load weight,assume that each cubic foot of storage space weighs approximately 35 pounds.Multiply 35 pounds by the amount of cubic feet in the cabinet and obtain theproduct load weight. For example, a 20 cubic foot refrigerator can holdapproximately 700 pounds of product (35 x 20) and assuming the refrigerator itselfweighs 300 pounds, the total combined weight of cabinet and product isapproximately 1000 pounds. Therefore, the floor in this example must be capable ofsupporting up to 1000 pounds.
