-
tioning units with remote air-cooled condensers (HCR - MCC)
HCR and MCC condensers are especially designed to be coupled with
the Liebert CRV (A type) air conditioning units power supplied at 50Hz
(CE market), within a standard range of external air temperature from
-20 °C to +46 °C.
The HCR and MCC family comes with a factory-installed stepless fan
speed controller especially designed and setted for usage with R410A
refrigerant and digital scroll refrigerant circuit.

The table shows the recommended combinations of the Air cooled Condensers (50Hz - CE mark) with the air conditioners Liebert CRV (50Hz - CE mark), according to the indicated max external
air temperature.
Connecting a too large capacity condenser (50% higher than the nominal capacity indicated in Tab. 7a) to the CRV unit can cause malfunctioning and incorrect condenser regulation at low ambient
temperature (e.g. in cold season).
The above indications are approximate and must be checked on the basis of other specific operating conditions.
For operating conditions other than those indicated in the table, refer to the New Hirating calculation software and to the air condenser service manual.
