3.5Preparing a 6-Fan or 8-Fan Condenser for Moving and Installation

3.5.1Removing the Skid and Attaching Slings

The following procedure is one recommended process for removing a Liebert condenser from its ship- ping skid. Other methods may be used, provided that the methods are safe for personnel, the con- denser and equipment.

1.Place a sling through to rigging attachment points as shown in Step 1 in Figure 14.

2.Raise the condenser high enough that the skid can be safely removed.

3.Place protective material under the unit to protect it from scrapes and gouges. Lower the condenser onto the material.

4.Lower the condenser to an angle and distance that will allow attaching the legs to one side of the condenser. The number of legs varies according to the condenser model.

5.Install the legs, provided by Liebert, on the condenser with the mounting bolts, also provided by Liebert. Liebert recommends using a 5/8" socket and ratchet.

6.Turn the condenser so that the legs just installed support one side of the unit as shown in Step 3 in Figure 14.

7.Remove the sling and it attach it to the opposite side of the condenser as shown in Step 4 in Figure 15.

8.Raise the condenser to an angle to safely install legs on the opposite side of the condenser.

9.Lower the condenser so all legs support it.

10.Place slings on both sides of the condenser to lift and move it to the installation location.
