Appendix B: Disassembling the DSE for Transport
The Liebert® DSE has a modular frame construction that allows separating the unit into three sections.
Each of these sections is more easily maneuvered through tight spaces or placed in small elevators.
A qualified service technician with the required tools and recommended assistance can disassemble an
air-cooled unit in about four hours, assuming refrigerant evacuation is not required.
This procedure requires four or more people for lifting the filter and electric-box assembly.
WARNING! Risk of over-pressurization of the refrigeration system. Can cause explosive
discharge of high-pressure refrigerant, loss of refrigerant, environmental pollution, equipment
damage, injury, or death. This unit contains fluids and gases under high pressure. Use extreme
caution when charging the refrigerant system. Do not pressurize the system higher than the
design pressure marked on the unit's nameplate. For systems requiring EU CE compliance
(50Hz), the system installer must provide and install a pressure relief valve in the high side
refrigerant circuit that is rated same as the refrigerant high side “Max Allowable Pressure”
rating that is marked on the unit serial tag. Do not install a shutoff valve between the
compressor and the field installed relief valve. The pressure relief valve must be CE-certified to
the EU Pressure Equipment Directive by an EU “Notified Body.”
WARNING! Risk of top-heavy unit falling over. Improper handling can cause equipment
damage, injury or death. Read all of the following instructions and verify that all lifting and
moving equipment is rated for the weight of the unit before attempting to move, lift, remove
packaging from or prepare the unit for installation.
CAUTION: Risk of contact with sharp edges and exposed fasteners. Can cause injury. Wear
appropriate, OSHA-approved personal protective equipment (PPE) when installing the
component.
CAUTION: Risk of handling heavy unit and component parts. Can cause injury and equipment
damage. Use OSHA-recommended safe lifting techniques and/or lifting equipment rated for the
weight of the unit.
