Vertiv Liebert CRV Plus, User Manual

Page: 6 / 98

The CRV+ unit isolation switch is inside the unit. The line side of this switch contains live high voltage.
In order to ensure there is no voltage inside the unit, install and open a remote isolation switch.
The unit contains fluids and gases under high pressure. Therefore, the pressure should be relieved
before working with the piping.
Various components such as compressors, refrigerant discharge lines, and humidifiers are extremely hot
during the unit operation. Therefore, allow sufficient time for the unit to cool down before working with
the unit cabinet. Handle the unit with extreme caution and wear safety equipment such as protective
gloves, safety shoes, and arm protection while working with the hot compressors, discharge lines, and
reheats.
There is a risk of leaking water that can cause damage to the equipment as well as the building. There
should be an effective water drain connection and facilities. Installation should be precise.
Implementation of the application and service practices should be suitable and fault-free. Not complying
with these norms will result in water leakage from the unit. Water leakage can result in massive damage
and loss of critical equipment in the hosting ecosystem. Therefore, care should be taken to ensure that
the unit must not be located directly above any equipment that could sustain damage due to water and
excessive moisture. Using a leak detection system for unit and system supply lines are recommended by
Vertiv Co.
