NOTICE
Risk of improper lubrication. May cause equipment damage.
Liebert XDCs refrigerant R-407C circuits with refrigerant charges over 55lb. (24.9kg) require
additional oil. See Figure 4.13 below for the amount required for various charge levels.
Once the system has been fully charged with refrigerant, use a hand pump to add the
additional oil at the suction side of the system while the system is running.
The amount of oil added by field service must be recorded on a tag attached at the tandem,
(the amount added along with the date it was added). This will be documented on a tag
located at the tandem compressor and marked “Oil Added Field Service Record.” Refer to the
Liebert XDC user manual, SL-16673, available at www.VertivCo.com.
