If damage is detected, or if shipment is incomplete, file a claim immediately with the shipping company. Step 2 — Rig and Place the Unit RIGGING On each end of the cooler, a steel loop is provided for the preferred method of lifting the unit. Use spreader bars to keep cables away from the compressor enclosure and control box. If unit is to be moved by fork truck, use the following methods: 1. From the front or rear, lift under the cooler rails. Unit can be either on or off the skid. 2. When moving from the ends, leave the unit on the skid. Lift from under the skid. If unit is to be dragged or rolled into final position, leave it on the skid; apply force only to the skid, not the unit. When rolling, use a minimum of 3 rollers. PLACEMENT When the unit is in final position, remove the skid, level the unit with a spirit level and bolt to the floor or pad. These units are not suitable for unprotected outdoor use. Carrier recommends that these units be located in the basement or on the ground floor. However, if it is necessary to locate the unit on an upper floor, be sure the structure has been designed to support the weight. If necessary, add structural support to the floor. Also, be sure the surface for installation is level. Refer to Fig. 1 for space requirements and Table 1 for weight distribution. Only electrical power connections and water con-, nections for condensers and cooler are required for installation. Step 3 — Check Compressor Mounting and Connections — As shipped, compressor is held down by special self-locking bolts and plain lock washers.
