Page 5: Important Safety Guidelines
The only way to ensure that there is NO voltage inside the unit is to install and open a remote disconnect switch. Refer to unit electrical schematic. Follow all local codes. Vertiv | Liebert® MC™ Installer/User Guide |... - Page 6 Fan motors, transformers, piping and other components may become extremely hot during normal operation. Wear thermally insulated gloves and appropriate protective clothing and allow time for components to cool when working within the cabinet or electric control enclosure. Vertiv | Liebert® MC™ Installer/User Guide |...
- Page 7 Care must be exercised to avoid damage to the compressor. Vertiv™ recommends connecting a sight glass between the charging hose and the compressor suction service valve. This will permit adjusting the cylinder hand valve so that liquid can leave the cylinder while allowing vapor to enter the compressor.

Page 78: Equipment Application Guidelines
Pump-down must be disabled on the indoor unit when using the Liebert MC condenser, due to the reduced volume in the condenser coil. Vertiv™ recommends adding a discharge line check valve and crankcase heater when connecting the Liebert MC condenser to Liebert indoor units built before 2012. The check valve and crankcase heater are needed for compressor protection. -
Page 79: Liebert Mc Condenser Charging With Liebert Dse™ Receivers
Care must be exercised to avoid damage to the compressor. Vertiv™ recommends connecting a sight glass between the charging hose and the compressor suction service valve.
