R22 Capacities are approximately the same as R407C capacities + 5%. Consult Liebert Applications Engineers for specific details.
1
At the following standard conditions: 24°C db; 50% R.H. (17°C wb) - condensing temperature: 49° C.
Power Supply Voltage 400/3/50, 50Pa ESP (External Static Pressure)
2
Max available ESP at quoted airflow
3
Measured in front of the unit at 1m height, 2 m distance, in the free field, fan and compressor run ning, 50Pa ESP.
4
Valve pressure drop + coil pressure drop.
5
Valve pressure drop + condenser pressure drop.
Note: Quoted capacities are gross capacities, for nett capacities, deduct fan motor kW. EER is based on i ndoor unit only. Unit air flow is quoted for standard
configuration, with a clean EU4 filter.
