This manual contains important safety instructions that should be followed during the installation
and maintenance of the Liebert CRV. Read this manual thoroughly before attempting to carry out
any operations on the Liebert CRV, including installation and operation. Retain this manual for the
entire service life of the Liebert CRV.
Only properly trained and 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.
Any operation that requires opening doors or equipment panels must be carried out only by properly
trained and qualified personnel.
Each machine is equipped with an electric insulation device that allows the operator to work safely.
Switch Off the machine with this electric insulation device before beginning any maintenance
operation to eliminate remaining risks (electric shocks, burns, automatic restarting, moving parts
and remote control).
The panel key supplied with the unit must be kept by the person responsible for maintenance. To
identify the unit by model and serial number in order to obtain assistance or spare parts, locate the
identification label on the outside of the unit.
A warning label on the front and back panels reminds users that:
• the Liebert CRV restarts automatically
• the main switch must be opened before opening the internal compartments for any operation.

WARNING
Risk of high temperatures, extreme cold and high-speed rotating fan blades. Can cause
equipment damage, injury and death.
Disconnect all local and remote electrical power supplies, confirm that all fan blades have
stopped rotating and allow the component temperatures to become safe for human contact
before opening doors and/or removing protective covers and working within.
If the doors are opened immediately after the Liebert CRV has been switched Off:
• some components, such as electrical heaters, compressor, outlet area and outlet piping, may
remain at high temperature about 212°F (100°C);
• some components, such as the evaporator, may remain at low temperature;
• fan blades may continue to rotate by inertia.
These residual risks are highlighted by warning labels on the Liebert CRV.

WARNING
Risk of explosive discharge from high-pressure refrigerant. Can cause injury and death.
This unit contains fluids and gases under high pressure. Relieve pressure before working with
piping.
!
WARNING
Risk of hair, clothing and jewelry entanglement with high speed rotating fan blades. Can
cause equipment damage, serious injury or death.
Keep hair, jewelry and loose clothing secured and away from rotating fan blades during
