Disassembling the Liebert DS for Transport

19.Cut the insulation and pull it back from the piping.

20.Cut the refrigerant piping with a tubing cutter; if there is no Schrader fitting, let the nitrogen bleed out before cutting all the way through the pipe.

NOTE

Emerson does not recommend unsweating refrigerant connections.

21.Unsweat or cut all copper water pipes that interconnect unit sections.

22.Immediately cap and seal all piping that has been cut, including the suction and liquid lines, as well as the fluid piping on GLYCOOL and dual-cool units.

6.2.1Remove the Compressor Assembly

1.Secure the compressor wire harness to the compressor assembly.

2.Remove the 10 thread-cutting bolts holding the compressor section assembly to the filter and electric box assembly and the blower and coil assembly.

There are five bolts in the front, four in the back and one on the top at the middle of the unit.

a.Begin removing bolts at the bottom of the unit and progress toward the top. Use this method for the front and back bolts.

b.Stabilize the compressor section before removing the top, middle bolt.

NOTICE

The compressor section is top-heavy and has a small base. It must remain upright. Do not lay the compressor section on its side during or after removing it from the Liebert DS. Do not remove shipping blocks from semi-hermetic compressors until the Liebert DS is fully reassembled and ready for installation.

NOTE

Emerson recommends using piano jacks when moving this section.

6.2.2Remove the Filter and Electric Box Assembly

1.Using a stepladder to reach the top of the Liebert DS, remove the filter support plate; it is attached to the filter and electric box assembly with two screws, one on each end.

2.Remove tags from the Schrader fittings on top of the coil headers. Retain the tags for replacement during reassembly.

3.Remove 16 screws, (8) on each side, from the evaporator top cover plate to coil assembly. Coil top blocker will remain with top section for rigidity.

4.Remove coil access plates from the left side of the Liebert DS.

5.Remove the four thread-cutting bolts securing the filter and electric box assembly to the blower and coil assembly. There are two on the left and two on the right.

6.Separate the unit sections with caution.

NOTICE

Risk of improper handling.

•The filter and electric box section should be moved forward and set on the floor.

•Make sure to lift the coil plate over the Schrader fittings on the headers. Emerson recommends using four people to remove this section. Special care is required when moving this section because the legs are not designed to withstand strong shocks.

•The blower and coil assembly must remain upright. The coil is not secured to the blower and coil assembly.

•Secure the coil to the bottom section with straps or a similar method before moving the section.

7.Move each section of the Liebert DS to the installation location.
