Note: All values are accurate to +/- 5% and based on full speed with standard filters.
Note: Reduce airflow and cooling capacity specifications by 7% for cooling units run at low input voltage (380 V).
Note: Any CW flow rate of 0.19 l/s - 0.32 l/s (3.0 GPM - 5.0 GPM) may cause an increased error in flow rate and power calculation. A fluid flow fault may result. Any flow rate under 0.19 l/s (3.0 GPM) may also display as 0 in the flow rate and power calculation. Note: For sustained operation, a maximimum flow rate of 2.2 l/s (34 GPM) is recommended. This may be exceeded by 25% for peak conditions.
* To convert feet of water to PSIG, use the following formula: ft H2O ÷ 2.307 = PSIG.
