IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important safety instructions that should be followed during the installation and maintenance of the Liebert Challenger 3000. Read this manual thoroughly before attempting to install or operate this unit.

Only qualified personnel should move, install or service this equipment.

Adhere to all warnings, cautions and installation, operating and safety instructions on the unit and in this manual. Follow all operating and user instructions.

! WARNING

Arc flash and electric shock hazard. Disconnect all local and remote electric power supplies and wear protective equipment per NFPA 70E before working within the electrical enclosure. Failure to comply can cause injury or death.

Customer must provide earth ground to unit per NEC, CEC and local codes as applicable.

Before proceeding with installation, read all instructions, verify that all the parts are included and check the nameplate to be sure the voltage matches available utility power.

The Liebert iCOM® microprocessor does not isolate power from the unit, even in the “Unit Off” mode. Some internal components require and receive power even during the “Unit Off” mode of Liebert iCOM control.

The factory-supplied optional disconnect switch is inside the unit. The line side of this switch contains live high-voltage.

The only way to ensure that there is NO voltage inside the unit is to install and open a remote disconnect switch and check the internal power with a voltmeter. Refer to unit electrical schematic.

Follow all local codes.

! WARNING

Risk of explosive discharge from high-pressure refrigerant. Can cause injury or death. This unit contains fluids and/or gases under high pressure.

Relieve pressure before working with piping.

! WARNING

Risk of refrigerant system rupture or explosion from overpressurization. Can cause equipment damage, injury or death.

Local building or plumbing codes may require that a fusible plug or other type of pressure relief device be installed in the system.

For systems requiring EU CE compliance (50Hz), the system installer must provide and install a discharge pressure relief valve rated for a maximum of 500psig (34bar) in the high side refrigerant circuit. 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.”

NOTE

The Liebert indoor cooling unit has a factory-installed high-pressure safety switch in the high side refrigerant circuit. A pressure relief valve is provided with Liebert Lee-Temp™condensers. Consult local building codes to determine whether the Liebert Fan Speed Control and VFD condensers will require field-provided pressure relief devices. A fusible plug kit for Liebert FSC and VFD condensers is available for field installation.
